  As described above, the program / data storage unit 12 stores a program for operating the control unit 11 and image data for displaying an operation auxiliary image selected by the operation image display unit 11c. Other than this, for example, a camera control program, an icon displayed on the screen, image data for a menu screen, and further temporary storage of image data acquired by the imaging unit 20 and adjustment for camera control Various data such as values are stored.

  The display control unit 15 displays a live view display at the time of shooting, a playback image at the time of playback, or a menu image. Also, processing such as superimposing an icon or the like on the live view image is performed according to the instruction. Further, the display control unit 15 superimposes the operation auxiliary image read from the program / data storage unit 12 on the live view image according to an instruction from the operation image display unit 11c. The display unit 16 has a display such as a liquid crystal monitor and an organic EL disposed on the back of the main body, and display control is performed by the display control unit 15.

  The touch panel 13 is integrated with the display unit 16 or disposed on the front surface of the display unit 16, detects that a user's finger or the like is in direct contact with or approaches, and outputs a detection result to the touch detection unit 11a. There are various types of touch panels such as a resistive film method, a capacitance method, a photoelectric sensor method, and any one of them may be adopted. A touch panel employing a photoelectric sensor method will be described later with reference to FIG.

  The operation unit 14 includes various operation buttons such as a button operation unit, a release button, a power switch, or a mode switching button, an operation dial, an operation key, and the like, and is an operation member for the user to set a mode, a parameter, and the like.

  The control unit 11 is connected to a bus 26, and an imaging unit 20, an image processing unit 21, a compression / decompression unit 22, a recording / playback unit 23, an image storage unit 24, and a communication unit 25 are connected to the bus 26. . The imaging unit 20 includes a photographing lens for forming a subject image, an imaging element for converting the subject image into image data, and a processing circuit thereof, a diaphragm and a shutter interposed in the optical path of the photographing lens, and the like. Including. Image data generated by the imaging unit 20 is output to the bus 26.

  The image processing unit 21 performs various image processing such as digital amplification (digital gain adjustment processing) of digital image data, color correction, gamma (γ) correction, contrast correction, live view display image generation, and moving image generation. . The compression / decompression unit 22 is a circuit for compressing still image or moving image image data temporarily stored in the program / data storage unit 12 by a compression method such as JPEG or TIFF, and decompressing the data for display. Note that image compression is not limited to JPEG or TIFF, and other compression methods can be applied.

  The recording / reproducing unit 23 stores the image data compressed in the compression / decompression unit 22 in the image storage unit 24, reads out the image data of the captured image stored in the image storage unit 24, and decompresses the image data in the compression / decompression unit 22. The expanded image data is reproduced and displayed. The image storage unit 24 is a recording medium for image data that can be built in or loaded into the digital camera body. The communication unit 25 transmits or receives image data or the like to an external device.

  Next, the structure of the photoelectric sensor type touch panel 13 integrated with the display unit 16 will be described with reference to FIG. 2A is a schematic diagram of a cross section of the touch panel 13 and the display unit 16 when the user's finger is close to the touch panel 13 and FIG. 2B is a case where the user's finger is in direct contact with the touch panel 13. FIG. In this touch panel, as shown in FIG. 2A, optical sensors 104 are two-dimensionally arranged in the liquid crystal unit 100 at a predetermined interval, and a backlight 102 is provided on the back surface of the liquid crystal unit 100. Yes.

  When the irradiation light 106a from the backlight 102 is not reflected by the user's finger 90, as shown in FIG. Further, when the user's finger 90 is slightly away from and in proximity to the touch panel 13, the irradiation light 106b is reflected by the finger 90 as shown in FIG. 2A, and a part of the reflected light is an optical sensor. 104.

  When the user's finger 81 approaches the touch panel 8b, the irradiation light 106b from the backlight 102 is reflected by the finger 90 and detected by the optical sensor 104 as shown in FIG. The detection result of the optical sensor 104 is sent to the touch detection unit 11a, and the touch position of the finger is detected depending on which optical sensor 104 detects the reflected light from the finger 90, and the time-series change of the touch position is detected. The movement of the finger can be detected based on the above.

  Next, a method for changing shooting conditions such as exposure correction and zooming by changing the operation mode on the touch panel 13 will be described with reference to FIGS. 3 to 5. In the present embodiment, the exposure correction is changed by touching the right side of the screen 50 with one hand, and the focal length is changed (zooming) by touching both sides of the screen 50 and performing a rotation operation. The aperture or shutter speed is changed by touching both sides of the lens and performing a slide operation.

  FIG. 3 shows a case where the user holding the digital camera with one hand changes the exposure correction amount. That is, the camera is set to the shooting mode, and the live view image is displayed on the screen 50 of the display unit 16. In the live view image at this time, the person 52a is located in the center of the room, and the outdoor scenery 52b spreads in the background. In this state, the person 52a in the center is dark and underexposed, while the background 52b is properly exposed.

  In general, exposure correction is often performed so that the person 52a located at the center has proper exposure. Therefore, when the user touches the right side of the screen 50 with one hand, the exposure correction bar 60 is displayed in the shape of a vertically long double arrow at the position on the right side of the screen 50 as shown in FIG. In the present embodiment, the exposure correction is set in advance as a corresponding change condition by a touch operation on the right side of the screen.

  When the touch detection unit 11c that has input the detection signal from the touch panel 13 detects that the touch is made at the right position, the change condition setting unit 11b sets the type of the change condition to “exposure”. When “exposure” is set by the change condition setting unit 11b, the operation image display unit 11c instructs the display of the exposure correction bar 60 as an operation auxiliary image for assisting the user's exposure correction operation, and the program / data Image data of the exposure correction bar 60 is read from the storage unit 12. The read image data of the exposure correction bar 60 is sent to the display control unit 15, and the exposure correction bar 60 is superimposed and displayed on the live view image. The parameter changing unit 11d sets exposure correction in the shooting condition item as a change condition. In the present embodiment, the exposure correction bar 60 is displayed according to the position touched on the screen 50, but is not limited thereto, and may be a fixed position regardless of the touch position, for example.

  As shown in FIG. 3A, when the exposure correction bar 60 is superimposed on the live view image, the user may slide his / her finger along the exposure correction bar 60 in the direction in which exposure correction is desired. The touch detection unit 11a detects the direction of the slide operation and notifies the parameter change unit 11d of the detection result. The parameter changing unit 11d changes the exposure correction value to the plus direction when the direction of the slide operation is upward, and changes the exposure correction value to the minus direction when the direction of the slide operation is downward. It should be noted that “+” or “−” may be displayed on the exposure correction bar 60 in order to display the direction of exposure correction in an easy-to-understand manner.

  Upon receiving the change notification from the parameter changing unit 11d, the parameter control unit 11e corrects the luminance gain of the imaging unit 20. As a result, as shown in FIG. 3B, in the live view image, the person 52a at the center of the screen is brightened and displayed clearly. On the other hand, the background 52b around the screen is overexposed and slightly overexposed. Of course, as the exposure correction, the aperture value and shutter speed of the imaging unit 20 may be changed.

  In the present embodiment, the condition related to the imaging unit 20 is changed by the parameter control unit 11e. However, depending on the type of change condition to be set, the condition of the image processing unit 20 may be changed. Good. The exposure correction amount is determined by the number of slides or the slide position. When determining by the number of slides, for example, when the slide is performed once, it is +0.5 level when it is slid, and when it is slid three times, it is brightened by 1.5 levels. When determining by the position of the slide, for example, the top position is set to +2 steps.

  Next, a case where the user who holds the digital camera with both hands changes the focal length (zooming) will be described with reference to FIG. When the touch detection unit 11a detects that the left and right sides of the screen 50 are touched with both hands and the rotation operation is performed with both fingers, the change condition setting unit 11b sets zooming as the type of the change condition. Next, as shown in FIG. 4A, the operation image display unit 11c displays, on the screen 50, an ellipse figure, ring 61, which makes the left and right touch positions elliptical ellipses as an operation auxiliary image. To do. Even when the left and right sides of the screen 50 are touched, if only one of the left and right fingers is moved, it is determined that the aperture / SS setting will be described later, and the zooming setting is not performed. That is, in a state where both fingers are placed on the screen 50, the operation assisting image is not displayed because there are two options depending on the subsequent finger movement.

  When the user rotates both fingers by touching the ring 61 as an operation auxiliary image, the touch detection unit 11a detects the rotation direction of the rotation operation, and the detected rotation direction is sent to the parameter change unit 11d. Notice. If the rotation direction is clockwise, the parameter changing unit 11d notifies the parameter control unit 11e of an instruction to increase the zoom parameter. On the other hand, when the rotation direction is counterclockwise, the parameter control unit 11e is notified of an instruction to decrease the zoom parameter.

  When the parameter control unit 11e receives an instruction to increase the zoom parameter, the focal length of the optical system of the imaging unit 20 is changed to the long focal side, and the zoom lens is moved in the direction of zooming up (long focal side). When zooming in, the subject is enlarged and displayed as shown in FIG. On the other hand, when an instruction to reduce the zoom parameter is received, the focal length of the optical system of the imaging unit 20 is changed to the short focus side, and the zoom lens is moved in the direction of zooming down (short focus side). Here, the amount of zoom-up or zoom-down is set according to the rotation angle detected by the touch detection unit 11a. For example, the focal length may be changed such that it is doubled when it is rotated +90 degrees and 1/2 times when it is rotated -90 degrees. The ring 61 is displayed not only in a stationary state as described above, but also by displaying a bright spot on the ellipse according to the position of the finger. You may make it the display which rotates up. In this case, when the focal length of the zoom lens reaches the long focal end or the short focal end, it is also possible to notify that the rotation by the finger has become invalid by stopping the movement of the bright spot.

  As a modification of the zoom process, a part of an image within a predetermined range may be trimmed from the entire image by an electronic zoom processing unit in the image processing unit 21 in accordance with an instruction from the parameter control unit 11e. In other words, the photographing zoom condition can be changed by either changing the focal length of the photographing lens, turning on / off the electronic zoom (magnification changing), or a combination thereof.

  In this embodiment, a ring-shaped image is adopted as an operation auxiliary image for zooming operation. This is due to the following reason. In a single-lens reflex camera, conventionally, the zoom operation is performed by rotating the zoom ring of the interchangeable lens, and it is easy to associate zoom with the auxiliary operation image of the ring. Further, since the zoom and the ring are related to each other in the camera, the discriminability can be improved by using a ring-shaped image as an operation auxiliary image for changing the zoom value.

  Next, a case where the user holding the digital camera with both hands changes the aperture value or the shutter speed (SS) will be described with reference to FIG. When the touch detection unit 11a detects that the left and right sides of the screen 50 are touched with both hands and the slide operation is performed with only one of the left and right fingers, the change condition setting unit 11b determines the type of the change condition. / SS (shutter speed) is set.

  In changing the aperture / SS condition, the aperture value is adjusted by the aperture actuator corresponding to the aperture diameter of the mechanical aperture incorporated in the imaging unit 20. The shutter speed is controlled by the timing of the mechanical shutter drive actuator when the image pickup unit 20 has a built-in mechanical shutter, and when the image pickup unit 20 does not have a built-in mechanical shutter, the image sensor 20 is a CCD. And the shutter speed of a CMOS element shutter.

  When the aperture / SS is set by the change condition setting unit 11b, the operation image display unit 11c displays the TV icon 62a on the upper left side of the screen 50 and the AV icon on the lower side as shown in FIG. 62b is displayed as an operation auxiliary image. The TV icon 62a displayed as TV is an icon for changing the shutter speed, and the AV icon 62b displayed as AV is an icon for changing the aperture value. One of the touched icons is selected.

  As shown in FIG. 5A, a slide bar 62c is displayed on the right side of the screen 50 by the operation image display unit 11c. The slide bar 62c has a shape of an arrow that is long in the vertical direction, and is an operation auxiliary image for changing a parameter selected from any one of the aperture / SS. In the present embodiment, the TV icon 62a, the AV icon 62b, and the slide bar 62c are displayed at the touched positions. However, the present invention is not limited to this, and it is of course possible to display it at the left and right determined positions.

  As shown in FIG. 5B, when the touch detection unit 11a detects that the user touches the TV icon 62b with the finger of the left hand and notifies this to the parameter change unit 11d, the parameter change unit 11d Set aperture change as a condition. Next, when the touch detection unit 11a detects that the user has performed a sliding operation with the finger of the right hand along the slide bar 62c and notifies the parameter change unit 11d of this, the parameter change unit 11d For example, F2.8 is set. The set aperture value is displayed on the aperture / SS display section 62d in the screen 50. The aperture value set by the parameter changing unit 11d is notified to the parameter control unit 11e, and the aperture of the imaging unit 20 is changed to F2.8 by an instruction from the parameter control unit 11e.

  As described above, in the present embodiment, the type of condition to be changed can be changed depending on the operation mode on the touch panel 13. For this reason, even if it is a touchscreen of a small screen, selection of the condition type to change becomes easy and it is effective especially for the touchscreen of a portable apparatus. As in the past, it is possible to eliminate the troublesomeness of selecting items on the menu screen of a small display unit.

  Next, the operation of the digital camera according to the first embodiment will be described using the flowcharts shown in FIGS. FIG. 6 shows a camera control flow. When a power supply battery is loaded in the digital camera, this camera control flow starts. First, it is determined whether the power is on (S11). In this step, the operation state of the power switch in the operation unit 14 is detected, and it is determined whether or not the power switch is on.

  If the result of determination in step S11 is that the power supply is not on, that is, if the power supply is off, a standby state is entered (S12). This standby state is a low power consumption mode, in which only the state of a specific operation switch such as a power switch is detected and other controls are stopped. When the standby state is exited, the process returns to step S11.

  If the result of determination in step S <b> 11 is that the power is on, it is next determined whether or not it is a shooting mode (S <b> 13). The shooting mode is a mode in which a shot image can be recorded by observing a subject image, determining a composition, and releasing a shutter. If the result of this determination is that the camera is in shooting mode, a live view image is displayed (S21). Here, the subject image is displayed in live view on the display unit 16 based on the image data acquired by the imaging unit 20.

  Once the live view image is displayed, the change condition is set (S22). In this step, as described with reference to FIGS. 3 to 5, when the user touches the screen 50 and performs a rotation operation or a slide operation by the touch, various shooting conditions such as exposure correction and zooming can be performed. Set the change. A detailed flow of this change condition setting will be described later with reference to FIG.

  Once the change condition has been set, it is next determined whether or not there has been a shooting instruction (S23). In this step, it is determined whether or not the release button in the operation unit 14 has been operated. If the result of this determination is that there is no shooting instruction, processing returns to step S11. On the other hand, if there is a photographing instruction, photographing and recording processing is performed (S24). Here, the image data acquired by the imaging unit 20 is subjected to image processing by the image processing unit 21, further compressed by the compression / decompression unit 22, and then recorded in the image storage unit 24 by the recording / reproducing unit 23.

  Once shooting and recording processing have been carried out, it is next determined whether or not the power is turned off (S25). Here, it is determined whether or not the power switch is turned off. If the result of this determination is that an off operation has not been performed, processing returns to step S11. On the other hand, when a power-off operation is performed, a power-off process is performed and an end state is entered.

  If the result of determination in step S13 is not shooting mode, it is next determined whether or not to play back (S14). Here, the determination is made based on the operation state of the playback button in the operation unit 14. If the result of this determination is reproduction, the image is then reproduced (S16). In the image reproduction, the image data of the photographed image recorded in the image storage unit 24 is read, decompressed by the compression / decompression unit 22, and then displayed on the display unit 16.

  Once image reproduction has been performed, it is next determined whether or not there is an image change instruction (S17). When the user desires to change the image to be viewed, the user is instructed to change the image using the operation member of the operation unit 14, so in this step it is determined whether or not this operation member has been operated. As a result of the determination, if there is no image change instruction, the process proceeds to step S25 described above. On the other hand, if there is an image change instruction, the image is changed according to this instruction (S18). Here, the instructed image is displayed on the display unit 16.

  If the result of determination in step S14 is not playback, image communication is carried out (S15). Here, image data of a captured image recorded in the image storage unit 24 is transmitted to an external device such as a personal computer or received from the external device via the communication unit 25. When the image communication ends, the process proceeds to step S25.

  Next, the change condition setting operation in step S22 will be described using the flowchart shown in FIG. When the change condition setting operation is started, first, it is determined whether or not the touch is at one place on the right (S31). Here, the detection result from the touch panel 13 is input by the touch detection unit 11a, and it is determined whether or not the right portion of the screen 50 of the display unit 16 is touched. If the left and right are touched at one place, it is determined as No here.

  If the result of determination in step S31 is that there is one touch on the right, next, exposure correction change setting is performed (S32). Here, as described with reference to FIG. 3, a change in exposure correction amount is set in accordance with a user input operation. The exposure correction change setting subroutine will be described later with reference to FIG. When the exposure correction change setting is executed, the flow returns to the original flow.

  If the result of determination in step S31 is that the touch is not at one place on the right, it is next determined whether or not the touch is at one place on the left and right (S33). Here, the detection result from the touch panel 13 is input by the touch detection unit 11a, and it is determined whether or not the right one place and the left one place on the screen 50 of the display unit 16 are touched simultaneously. If the result of this determination is that the left and right locations are not touched one by one, the flow returns to the original flow.

  If the result of determination in step S33 is that one touch has been made on the left and right, it is next determined whether or not there is a turning operation on the left and right (S34). If the result of determination in step S33 is Yes, the user is holding the digital camera with both hands. In this step S34, whether or not the screen 50 has been touched so as to be further rotated with the fingers of both hands. Is determined by the touch detection unit 11a.

  If the result of determination in step S34 is that left and right rotation operations have been made, zoom change settings are made (S35). Here, as described with reference to FIG. 4, the focal length setting is changed, that is, zooming is performed in accordance with the user's rotation operation state. The zoom change setting subroutine will be described later with reference to FIG. When the zoom change setting is executed, the flow returns to the original flow.

  If the result of determination in step S34 is that left and right rotation operations have not been performed, it is next determined whether or not slide operation has been performed on either left or right (S36). If the result of determination in step S33 is Yes, the user is holding the digital camera with both hands, and the result of determination in step S34 is that the user has not performed a turning operation with the fingers of both hands. In the step, it is determined by the touch detection unit 11a whether or not the user touches the screen 50 with any of the left and right fingers.

  If the result of determination in step S36 is that a slide operation has not been performed on either the left or right side, the flow returns to the original flow. On the other hand, if the result of determination is that a slide operation has been performed on either the left or right side, then aperture / SS change setting is performed (S37). Here, as described with reference to FIG. 5, with respect to the aperture or shutter speed selected by the user's left hand finger, the setting of the aperture value or shutter speed is changed according to the slide operation state with the right hand finger. . This aperture / SS change setting subroutine will be described later with reference to FIG. When the aperture / SS change setting is executed, the original flow is restored.

  Next, the exposure correction change setting subroutine in step S32 (see FIG. 7) will be described with reference to the flowchart shown in FIG. If the exposure correction change setting flow is entered, first, exposure correction is set as a change condition (S41). Here, exposure correction is set as the change condition by the change condition setting unit 11b.

  Subsequently, an exposure correction bar is displayed at the touch position as an operation auxiliary image (S42). As shown in FIG. 3A, the operation image display unit 11c displays the exposure correction bar 60 on the screen 50 at the touch position of the user. Subsequently, it is determined whether or not a slide operation has been detected in the vicinity of the bar (S43). Here, the touch detection unit 11a detects whether or not the user's finger is touching in the vertical direction in the vicinity of the exposure correction bar 60.

  If the result of determination in step S43 is that no slide operation has been detected, processing returns to step S41. On the other hand, if a slide operation is detected, the exposure correction parameter is changed according to the slide amount (S44). Here, the exposure correction amount is changed by the parameter changing unit 11d in accordance with the slide amount detected by the touch detection unit 11a.

  Once the exposure correction parameter is changed, the parameter control unit 11e then changes the luminance gain of the imaging unit 20 (S45). When the exposure correction amount is changed, the person 52a shown in FIG. 3A becomes brighter and clearly displayed as shown in FIG. 3B. On the other hand, the background 52b around the screen is overexposed and slightly overexposed. In addition to changing the gain of the imaging unit 20, it is of course possible to change the aperture value and shutter speed of the imaging unit 20 as described above. When the gain is changed, the original flow is restored.

  Next, the zoom change setting subroutine in step S35 (see FIG. 7) will be described with reference to the flowchart shown in FIG. In the zoom correction change setting flow, first, zoom correction is set as a change condition (S51). Here, zoom is set as a change condition by the change condition setting unit 11b.

  Subsequently, a ring is displayed at the touch position as an operation auxiliary image (S52). As shown in FIG. 4A, the operation image display unit 11c displays a ring 61 on the screen 50, in which two touch positions by the fingers of both hands of the user are ellipses. Subsequently, it is determined whether or not the rotation is clockwise (S53). Here, the touch detection unit 11a detects whether or not the user's finger is touching clockwise (clockwise) along the ellipse around the ellipse of the ring 61.

  If the result of determination in step S53 is that the rotation is clockwise, then the parameter changing unit 11d performs a change to increase the zoom parameter (S54). On the other hand, if the rotation is not clockwise, that is, if it is counterclockwise, the parameter changing unit 11d changes the zoom parameter (S55).

  If the zoom parameter is changed in step S54 or S55, the focal length of the imaging unit 20 is then changed (S56). Here, the focal length of the optical system of the imaging unit 20 is changed by the parameter control unit 11e in the zoom-up or zoom-down direction set by the parameter change unit 11d. Note that the zoom-up amount or zoom-down amount at this time is set according to the rotation angle detected by the touch detection unit 11a as described above. When the focal length of the imaging unit is changed, the original flow is restored.

  Next, the aperture / SS change setting subroutine in step S37 (see FIG. 7) will be described with reference to the flowchart shown in FIG. In the aperture / SS change setting flow, first, aperture / SS is set as a change condition (S61). Here, the aperture and shutter speed are set as the change conditions by the change condition setting unit 11b.

  Subsequently, the operation auxiliary image is displayed at the left and right positions (S62). As shown in FIG. 5A, the operation image display unit 11c displays the TV icon 62a and the AV icon 62b at the left touch position on the screen 50, and displays the slide bar 62c at the right touch position. Subsequently, it is determined whether AV selection has been performed (S63). Here, it is detected whether or not the vicinity of the AV icon 62b is touched by the touch detection unit 11a.

  If the result of determination in step S63 is AV selection, the change condition setting unit 11b sets the aperture as the change condition (S64). On the other hand, if the result of determination is that AV selection has not been made, that is, if the TV icon 62a has been selected, the change condition setting unit 11b sets SS (shutter speed) as the change condition (S65).

  If the change condition is set in step S64 or S65, it is next determined whether or not a right slide movement is detected (S66). Here, it is determined by the touch detection unit 11 a whether the user's finger is not touching the screen 50 along the slide bar 62. If the result of this determination is that no right slide movement has been detected, processing returns to the original flow.

  On the other hand, if the result of determination in step S66 is that a right slide movement has been detected, then the parameter is changed according to the slide amount (S67). Here, the parameter changing unit 11d changes the aperture value or the shutter speed (SS) according to the slide amount detected by the touch detection unit 11a. Subsequently, the changed parameter is displayed (S68). Here, as described above, the information is displayed on the aperture / SS display unit 62d (see FIG. 5B), so that the user can check the changed aperture value and shutter speed.

  Next, predetermined parameters of the imaging unit are changed (S69). Here, the parameter control unit 11e changes the parameter (control value) of the aperture or shutter speed. Subsequently, the conditions of the imaging unit 20 are changed (S70). Here, the aperture value or shutter speed value of the imaging unit 20 is replaced with a changed value, and control is performed according to the changed value at the time of shutter release. When the conditions of the imaging unit are changed, the original flow is restored.

  As described above, in the first embodiment of the present invention, it is possible to easily set which condition, for example, the exposure correction value, the zoom value, or the like is changed according to the touch state on the touch panel 13. it can. For this reason, even if it is a touchscreen of a small screen, a screen does not become complicated.

  Moreover, in this embodiment, the operation assistance image is displayed according to the changed conditions. Therefore, the user can easily set parameters along the operation assistance image.

  In the present embodiment, when the zoom change setting is performed, this setting is performed when the left and right portions of the screen 50 are touched one by one and the left and right are simultaneously rotated. However, if the left and right are touched one by one, of course, the zoom change setting may be performed when the rotation operation is performed on either one of the left and right at the same time. In this case, the step 34 (see FIG. 7) may determine “Is the left or right turning operation?”.

  Next, a second embodiment of the present invention will be described with reference to FIG. In the first embodiment, even if the fingers of both hands are placed on the screen 50, until the next operation, whether the zoom or the aperture / SS is not determined until the next operation is performed. However, in the second embodiment, whether the zoom or the aperture / SS is selected can be distinguished by the first mode of touch. The configuration of the second embodiment is the same as that of the first embodiment, and the flowchart is the same as that of the first embodiment except that the change condition setting flowchart shown in FIG. 7 is changed to the flowchart shown in FIG. . Therefore, the difference will be mainly described.

  If the change condition setting flow shown in FIG. 11 is entered, it is first determined whether or not the touch is at one place on the right (S71). Here, as in step S31, the touch detection unit 11a determines whether or not one place on the right side of the screen 50 is touched. If the result of this determination is that the touch is at one place on the right, exposure correction change settings are made as in S32 (S72). The flow of this exposure correction change is the same as the flow in the first embodiment shown in FIG. When the exposure correction change setting is executed, the original flow is restored.

  If the result of determination in step S71 is that the touch is not at one place on the right, it is next determined whether or not the touch is at one place on the left (S73). Here, it is determined by the touch detection unit 11a whether or not the left portion of the screen 50 is touched. If the result of this determination is that one place on the left has been touched, then aperture / SS change setting is performed as in step S37 (S74). The flow for changing the aperture / SS is the same as the flow in the first embodiment shown in FIG. When the aperture / SS change setting is executed, the flow returns to the original flow.

  If the result of determination in step S73 is that the touch is not at one place on the left, next, as in step S33, it is determined whether or not the touch is left and right at one place (S75). Here, it is determined whether the touch detection unit 11a is touching the left and right one at a time. If the result of this determination is that the left and right locations are not touched one by one, the flow returns to the original flow. On the other hand, if the result of determination is that one touch has been made on the left and right, zoom change setting is performed as in step S35 (S76). The zoom change flow is the same as the flow in the first embodiment shown in FIG. When the zoom change setting is executed, the flow returns to the original flow.

  As described above, in the second embodiment of the present invention, the change of the zoom and the aperture / SS can be distinguished by the first mode of touch. That is, if the touch is in one place on the left in step S73, the aperture / SS change setting is immediately executed. If the touch is not in one place on the left, it is confirmed that the left and right places are touched simultaneously. The zoom change setting is executed after confirmation. For this reason, it is possible to quickly move to the next operation.

  Next, a third embodiment of the present invention will be described with reference to FIGS. In the first embodiment, the ring 61 is single and the zoom is set as the change condition. In the third embodiment, rings having different diameters are displayed as operation auxiliary images so that different conditions can be changed. The configuration of the third embodiment is the same as that of the first embodiment, and the flowchart is the same as that of the first embodiment, except that the change condition setting flowchart shown in FIG. 7 is changed to the flowchart shown in FIG. . Therefore, the difference will be mainly described.

  Before explaining the flowchart shown in FIG. 13, how to change the conditions will be described with reference to FIG. 12 and an example of ring display in the present embodiment. In FIG. 12A, fingers are placed toward the left and right edges of the screen 50, and the outer ring 63a and the inner ring 63b are displayed on the screen 50 by the operation image display unit 11c. It shows a state of touching so as to rotate along the ring 63a.

  At this time, a finger 90a indicated by a broken line is placed on the left and right sides of the screen 50, and the finger 90a moves in the clockwise direction p along the outer ring 63a. In other words, to the finger 90b indicated by a solid line And when the left and right fingers are at the edge of the screen 50 (both left and right within the range of X1), the change condition is changed by the change condition setting unit 11b. Set to The above-described X1 may be a numerical value that is, for example, about 1/6 of the entire screen width, but may be appropriately changed according to the aspect ratio of the screen.

  The touch detection unit 11a detects the amount of rotation at this time, and is changed so that the zoom parameter is increased by the parameter change unit 11d according to the angle of the rotation operation, and the focal length of the imaging unit 20 is changed by the parameter control unit 11e. Controlled to move to long focus. In addition, when the finger 90a moves while touching so as to rotate counterclockwise along the outer ring 63a, the zoom parameter is changed so as to decrease depending on the angle of the rotation operation at this time. The parameter control unit 11e controls the imaging unit 20 so that the focal length moves to a short focal point.

  FIG. 12B shows a state in which fingers of both hands are placed on the inner peripheral ring 63b of the screen 50 and are touched so as to rotate along the inner peripheral ring 63b. When it is detected that the positions where the left and right fingers are initially placed are inward of the aforementioned X1 and the rotation operation is started, the change condition is set by the change condition setting unit 11b. Set as change operation.

  The touch detection unit 11a detects the rotation direction and the rotation amount at this time, and when the rotation direction is clockwise (clockwise, p direction in the figure), the parameter changing unit 11d performs focusing. The parameter is set to a short distance, and is changed to a short distance value depending on the angle of the rotation operation. When the rotation direction is counterclockwise (counterclockwise, the direction opposite to the p direction in the figure), the parameter changing unit 11d sets the focus parameter to a long distance, and the distance varies depending on the angle of the rotation operation. Changed to distance value.

  The parameter control unit 11e moves the focus lens of the imaging unit 20 to the near distance side or the far distance side according to the short distance and the short distance value set by the parameter changing unit 11d or according to the long distance and the long distance value.

  Next, the change condition setting operation in this embodiment will be described with reference to the flowchart shown in FIG. In the change condition setting in the present embodiment, steps S31 to S34, S36, and S37 are the same in the change condition setting flow shown in FIG. 7 in the first embodiment. Step numbers are given, and detailed explanations are omitted.

  In the change condition setting flow shown in FIG. 13, in step S34, it is determined whether or not the left / right rotation operation has been performed. If the left / right rotation operation has been performed, the zoom / focus is next adjusted. The change condition is set (S81). That is, when the touch detection unit 11a detects that the left and right sides of the screen 50 are touched simultaneously, the change condition setting unit 11b sets zoom / focus as a change condition.

  Subsequently, a double ring display is performed as an operation auxiliary image (S82). Here, the outer ring 63a and the inner ring 63b are displayed on the screen 50 of the display unit 16 by the operation image display unit 11c. Next, it is determined whether or not the first touch position is the outer periphery (S83). Here, the first touch position is detected by the touch detection unit 11a, and it is determined whether or not this position is within the range of X1. If it is within the range of X1, it is determined that it is on the outer periphery.

  If the result of determination in step S83 is that the first touch position is on the outer periphery, zoom is set as a change condition in the change condition setting section 11b (S84). Subsequently, it is determined whether the rotation is clockwise (S85). Here, it determines based on the detection result of the touch detection part 11a. If the result of this determination is clockwise, the parameter changing unit 11d changes the focal length to be longer (S86). On the other hand, if the result of determination in step S85 is not clockwise, that is, if it is counterclockwise, the parameter changing unit 11d changes the focal length to shorten (S87).

  If the focal length is changed in step S86 or S87, the focal length of the imaging unit 20 is then changed (S88). Here, the parameter control unit 11e moves the zoom lens of the imaging unit 20 to the long focus side or the short focus side according to the change result by the parameter change unit 11d. When the focal length of the imaging unit is changed, the original flow is restored.

  If the result of determination in step S83 is that the first touch position is not the outer periphery, that is, if it is the inner periphery, then the focus is set as the change condition in the change condition setting unit 11b (S91). Subsequently, it is determined whether or not the rotation is clockwise (S92). Here, it determines based on the detection result of the touch detection part 11a. If the result of this determination is clockwise, the parameter changing unit 11d changes the focus to the near distance direction (S93). On the other hand, if the result of determination in step S92 is not clockwise, that is, if it is counterclockwise, the parameter changing unit 11d changes the focus in an infinite direction (S94).

  If the focus direction is changed in step S93 or S94, the focus of the imaging unit 20 is then changed (S95). Here, the parameter control unit 11e moves the focus lens of the imaging unit 20 to the short distance side or the long distance side according to the change result by the parameter change unit 11d. When the focus of the imaging unit is changed, the original flow is restored.

  As described above, in the third embodiment of the present invention, since the ring is doubled, two types of conditions can be selectively changed depending on the difference in the diameter of the rotation operation.

  In the present embodiment, the double ring of the outer ring 63a and the inner ring 63b is always displayed regardless of whether the finger is placed near the center or the end of the screen 50. However, only one of the rings may be displayed according to the position where the finger is placed.

  In the present embodiment, the ring is double. However, the ring is not limited to this, and may be triple or more. In the case of triple, a larger number of conditions can be selectively changed.

  Next, a fourth embodiment of the present invention will be described with reference to FIGS. In the third embodiment, a plurality of rings as operation assistance images are displayed concentrically. In the fourth embodiment, the centers of the plurality of rings are shifted and positioned. The configuration of the fourth embodiment is the same as that of the first embodiment, and the flowchart is the same as that of the first embodiment except that the change condition setting flowchart shown in FIG. 7 is changed to the flowchart shown in FIG. . Therefore, the difference will be mainly described.

  Before explaining the flowchart shown in FIG. 16, how to change the conditions will be described with reference to FIG. 14 and an example of ring display in the present embodiment. FIG. 14A is a diagram illustrating a state in which zoom is set as a change condition when both fingers are simultaneously touched on the upper right side of the screen 50. That is, when the touch detection unit 11a detects that both fingers are simultaneously touched on the upper right side (first quadrant) of the screen 50, the change condition setting unit 11b sets zoom as the type of change condition.

  Subsequently, a circle 64a passing through the two touch positions is displayed on the screen 50 by the auxiliary image display unit 11c. In addition, “zoom” is displayed at the center 64ac of the circle 64a as the name of the change condition. As in the other embodiments, when the user's fingers move along the circle 64a while touching, the focal length is changed. Here, when the rotation operation direction is clockwise (clockwise), the zoom is increased. Conversely, when the rotation operation direction is counterclockwise (counterclockwise), the zoom is down.

  FIG. 14B is a diagram illustrating a state in which focus is set as a change condition when both fingers of both hands are simultaneously touched on the lower right side of the screen 50. That is, when the touch detection unit 11a detects that both fingers are simultaneously touched on the lower right side (fourth quadrant) of the screen 50, the change condition setting unit 11b sets the focus as the type of the change condition.

  Subsequently, the auxiliary image display unit 11c displays on the screen 50 a circle 64b that passes through the two touch positions. In addition, “focus” is displayed as the name of the change condition at the center 64bc of the circle 64b. When the user's fingers move along the circle 64b while touching, the focus is changed. Here, when the rotation operation direction is clockwise (clockwise), the distance is short, and conversely when the rotation operation direction is counterclockwise (counterclockwise), the distance is long.

  FIG. 14C shows an example of a screen on which both a zoom circle 64a and a focus circle 64b are displayed. After displaying the zoom circle 64a in FIG. 14 (a), if a certain time (for example, 1 second) elapses without any operation, the circle 64a is erased, but the positions of both fingers are lowered within the certain time. When the rotation operation is performed again, the focus circle 64b is displayed in addition to the zoom circle 64a. It does not matter if the circles intersect.

  The order of selecting zoom and focus may be reversed, and the number of circles displayed may be three or more. For example, the entire screen 50 is divided into four, and an operation auxiliary image is displayed in four areas of upper right (first quadrant), upper left (second quadrant), lower left (third quadrant), and lower right (fourth quadrant). Independent circles may be displayed. A flow shown in FIG. 16 described later is an example of displaying these four circles.

  Next, a method for calculating the diameter and center position of a circle to be displayed from the positions of both fingers touching the screen 50 will be described with reference to FIG. In FIG. 14, the change condition setting unit 11b sets the type of the touched position change condition. This is a circle setting method at this time.

The coordinates of the approximate center of the position 91a touched by the right finger detected by the touch detection unit 11a is (x1, y1), and the coordinates of the approximate center of the position 91b touched by the left finger is (x2, y2). To do. At this time, the touch detection unit 11a calculates the radius R of the circle and the coordinates (x3, y3) of the center 91c of the circle based on the following equations (1) to (3).
R = (((x1-x2) ² + (y1-y2) ² ) ^0.5 ) / 2 (1)
x3 = (x1 + x2) / 2 (2)
y3 = (y1 + y2) / 2 (3)

  Next, the change condition setting operation in this embodiment will be described with reference to the flowchart shown in FIG. If the change condition setting flow is entered, first, a ring display is performed at the two-hand touch position (S101). Here, based on the position where the fingers of both hands touch detected by the touch detection unit 11a, the diameter and center position of the circle are obtained using the above-described equations (1) to (3), and the ring is operated as an auxiliary operation image. Display as.

  Subsequently, it is determined whether or not the center is in the first quadrant (S102). Here, based on the center position of the circle calculated in step S101, it is determined whether it is included in the first quadrant. If the result of this determination is that the center is in the first quadrant, it is next determined whether or not the diameter is greater than half the screen width (S103). Here, the determination is made based on the diameter of the circle calculated in step S101. In the present embodiment, since the screen is divided into four as the determination value, the screen width is half. However, the present invention is not limited to this, and the design value may be changed as appropriate.

  If the result of determination in step S103 is that the diameter is greater than half the screen width, then the zoom change 1 pitch is set to a small value (S104). On the other hand, if the result of determination is not great, then the zoom change 1 pitch is set to a large value (S105). The change 1 pitch in steps S104 and S105 may be set relatively larger than the change 1 pitch in step S105. Here, for example, if the focal length of the imaging unit 20 is 10 × zoom of 10 mm to 100 mm, and the change pitch is small, the rotation is 10 mm / 90 degrees, and the large change is 30 mm / 90 degrees. In this case, the change pitch is set to a small value. On the other hand, if it is desired to make a fine change, the change pitch may be set to a large value.

  If the zoom change 1 pitch is set in step S104 or S105, next, zoom processing is performed (S106). Here, the parameter control unit 11e changes the focal length of the zoom lens of the imaging unit 20 by using the set zoom change 1 pitch in steps S104 and S105. When zoom processing is performed, the original flow is restored.

  If the result of determination in step S102 is that the center is not in the first quadrant, it is determined whether or not the center is in the second quadrant (S107). Here, based on the center position of the circle calculated in step S101, it is determined whether or not it is included in the second quadrant. If the result of this determination is that the center is in the second quadrant, then SS change processing is performed (S108). Here, processing for changing the shutter speed is performed. The shutter speed is changed to the high speed side or changed to the low speed side according to the direction of the displayed rotation operation of the ring. If SS change processing is performed, it will return to the original flow.

  If the result of determination in step S107 is that the center is not in the second quadrant, it is determined whether or not the center is in the third quadrant (S109). Here, based on the center position of the circle calculated in step S101, it is determined whether or not it is included in the third quadrant. If the result of this determination is that the center is in the third quadrant, then aperture change processing is performed (S110). Here, processing for changing the aperture value is performed. The aperture value is changed to the open side or changed to the aperture side according to the direction of the displayed ring rotation operation. When the aperture change process is performed, the original flow is restored.
