  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a digital camera 1 according to the present embodiment. The digital camera 1 according to this embodiment includes a camera body 100 and a lens unit 200.

  The camera body 100 includes a controller 111, an image sensor 121, a power switch 131, a release switch 132, a setting switch 133, a touch panel monitor 141, and a memory card adapter 151. The controller 111, the image sensor 121, and the memory card adapter 151 are built in the case 101 of the camera body 100. Further, the power switch 131, the release switch 132, the setting switch 133 and the touch panel monitor 141 are exposed outside the case 101.

  A case 101 of the camera body 100 has a memory card slot 102 built in. The memory card M can be inserted into the memory card slot 102 and connected to the memory card adapter 151. In a state where the memory card M is connected to the memory card adapter 151, the controller 111 can store image data and the like captured by accessing the memory card M in the memory card M.

  An opening 103 for attaching the lens unit 200 is provided in the case 101 of the camera body 100 in the vicinity of the imaging sensor 121. In a state where the lens unit 200 is attached to the opening 103, an image formed by the lens unit 200 is formed on the light receiving surface of the imaging sensor 121. The imaging sensor 121 transmits a video signal corresponding to the image formed on the light receiving surface to the controller 111. The controller 111 processes the video signal sent from the imaging sensor 121 to generate a video signal in a predetermined format, and transmits this to the touch panel monitor 141. The image sensor 121 normally outputs a video signal for one frame periodically (in a state where the release switch 132 is not pressed), for example (every 1/60 seconds), and the controller 111 sequentially receives the received video signal. Processing. For this reason, the image captured by the lens unit 200 is displayed on the touch panel monitor 141 as a moving image. The user of the digital camera 1 can take a picture while confirming the moving image displayed on the touch panel monitor 141.

  As shown in FIG. 1, the power switch 131, the release switch 132, and the setting switch 133 are connected to the controller 111. When each switch is operated, the controller 111 executes each function assigned to each switch. Is configured to do.

  The power switch 131 is a switch for switching between a photographing mode and a standby mode. In the standby mode, the controller 111 stops power supply to the imaging sensor 121, the touch panel monitor 141, the memory card adapter 151, and the motor (described later) of the lens unit 200, and the controller 111 itself operates in the power saving mode. Become. As a result, the power consumption of the digital camera 1 is kept extremely small. When the power switch 131 is pressed in the standby mode, the controller 111 shifts from the power saving mode to the normal mode and restarts the power supply to the motors of the imaging sensor 121, the touch panel monitor 141, the memory card adapter 151, and the lens unit 200 ( Shooting mode).

  When the setting switch 133 is pressed in the shooting mode, a menu screen is displayed on the touch panel monitor 141. A user of the digital camera 1 can perform various settings by operating a menu screen displayed on the touch panel monitor 141. For example, it is possible to select whether to shoot a still image or a moving image.

  When still image shooting is selected in the shooting mode, when the release switch 132 is pressed, the image sensor 121 causes the image formed on the light receiving surface of the image sensor 121 to have a high image quality for one frame. Output as a video signal. Then, the controller 111 displays still image data obtained by processing the high-quality video signal output from the imaging sensor 121 as a still image on the touch panel monitor 141 and causes the memory card M to store the still image data.

  On the other hand, when the shooting mode is selected and the shooting of the moving image is selected, when the release switch 132 is pressed, the controller 111 converts the moving image data obtained by sequentially processing the video signal output from the imaging sensor 121, The image is displayed as a moving image on the touch panel monitor 141 and stored in the memory card M. Note that moving image shooting is ended when the release switch 132 is pressed again or when a preset time has elapsed.

  The lens barrel 201 of the lens unit 200 is provided with a focus position adjustment ring 211, a zoom adjustment ring 212, and an aperture adjustment ring 213. The user of the digital camera 1 can adjust the focal length, zoom, and aperture value by rotating the focus position adjusting ring 211, the zoom adjusting ring 212, and the aperture adjusting ring 213.

  The lens unit 200 includes first, second, and third stepping motors 221, 222, and 223 that drive the focus position adjustment ring 211, the zoom adjustment ring 212, and the aperture adjustment ring 213, respectively. The controller 111 of the camera body 100 can adjust the focal length, zoom, and aperture value by controlling the first, second, and third stepping motors 221, 222, and 223. The focal position adjustment ring 211, the zoom adjustment ring 212, and the aperture adjustment ring 213 incorporate a rotary encoder (not shown), and the controller 111 of the camera body 100 adjusts the focal position from the output of each rotary encoder. The rotation angles of the ring 211, the zoom adjustment ring 212, and the aperture adjustment ring 213, that is, the focal position (focus distance) of the lens unit 200, the zoom and the aperture value can be detected.

  The digital camera 1 of the present embodiment can add image effects such as fade-in / fade-out during moving image shooting (action function). Hereinafter, the action function of the digital camera 1 of the present embodiment will be described. The action function is realized by the camera body controller 111 executing the following processing as a program.

  When the action function is validated or the detailed setting of the action function is performed, the setting switch 133 is operated to display the menu screen on the touch panel monitor 141 and the menu screen is operated.

  FIG. 2 is an action selection screen displayed on the touch panel monitor 141 when shooting a moving image with the action function enabled. As shown in FIG. 2, action selection buttons B11 and B12 on which “preset action” and “custom action” are displayed are displayed on the action selection screen. The “preset action” is a mode for shooting according to a fixed action condition (shooting condition) set in advance in the digital camera 1, and the “custom action” is a mode for shooting according to an action condition set by the user.

  When the action selection button B11 is selected by the touch panel operation, the preset action selection screen shown in FIG. 3 is displayed on the touch panel monitor 141. On the preset action selection screen, as shown in FIG. 3, “Fade In”, “Fade Out”, “Focus In”, “Focus Out”, “Color In”, “Color Out”, “Depth Plus”, “ Preset action buttons B21a, B21b, B22a, B22b, B23a, B23b, B24a and B24b described as “depth minus”, a custom action button B25 described as “custom”, and a completion button B26 are displayed. When one of the preset action buttons B21a to B24b is selected by touch panel operation and then the completion button B29 is operated, the preset action selected on the preset action selection screen is registered. When the release switch 132 is pressed, shooting is performed with the registered preset action. Further, when any one of the preset action buttons B21a to B24b is selected by a touch panel operation and then the custom action button B25 is operated, shooting may be executed after temporarily changing the action condition of the selected preset action. Yes (described later).

  Details of each preset action will be described below. FIG. 4 shows an example of a moving image when the “fade in” preset action is executed. Note that the six images displayed in FIG. 4 are extracted from the moving image obtained by executing the “fade in” preset action, and are shown on the lower side from the state of the image shown on the upper side. It shows that the image is gradually shifted to the image state. As shown in FIG. 4, when the “fade in” preset action is executed, the captured moving image gradually becomes brighter as time passes. Specifically, when the “fade in” preset action is executed, the controller 111 drives the third stepping motor 223 based on the relationship between the aperture value and time set in advance in the digital camera 1. Then, photographing is performed while gradually increasing the aperture of the aperture adjusting ring 213. As another embodiment, the controller 111 performs control while gradually increasing the sensitivity of the imaging sensor 121 to perform shooting while gradually increasing the brightness of the entire image. Alternatively, the controller 111 performs shooting while gradually decreasing the shutter speed based on the relationship between the shutter speed and time set in advance in the digital camera 1 (lengthens the time during which the shutter is open). Alternatively, it is possible to take a picture while gradually increasing the luminance value of the image by image processing by the controller 111. These may be used in combination as appropriate. In contrast to the “fade in” preset action, the “fade out” preset action gradually darkens the brightness of the moving image to be shot. Note that the time during which the “fade-in” process is performed (that is, the time required for the image to shift from the darkest state to the brightest state) is fixed. The same applies to the “fade out” process.

  FIG. 5 shows a moving image when the “focus in” preset action is executed. Note that the six images displayed in FIG. 5 are extracted from the moving image obtained by executing the “focus in” preset action, and are shown on the lower side from the state of the image shown on the upper side. It shows that the image is gradually shifted to the image state. As shown in FIG. 5, when the “focus-in” preset action is executed, the moving image is initially in a state where the subject image (main subject) at a predetermined distance is not in focus (in the shooting screen). Including a state where no focus is found anywhere), and gradually shifts to a state where the main subject is in focus as time passes. The “focus-in” preset action is realized by the controller 111 driving the first stepping motor 221. Specifically, first, the first stepping motor 221 is driven without taking (recording) a moving image, and the state in which the contrast value of the image of the main subject is maximized is determined to be in focus. The position of the focus position adjusting ring 211 at that time is recorded. Next, the focus position adjustment ring 211 is sufficiently moved by the first stepping motor 221 so that the main subject is not in focus, and moving image shooting is started. Then, the first stepping motor 221 is driven so as to gradually approach the recorded position while capturing a moving image. In contrast to the “focus in” preset action, the “focus out” preset action gradually shifts from a state in which the main subject is in focus to a state in which the main subject is not in focus. Note that the time during which the “focus-in” process is performed (that is, the time required to shift from the unfocused state to the focused state) is fixed. The same applies to the “focus out” process.

  The “color in” preset action is an action for gradually shifting from a black and white state to a color image. This action is realized by gradually increasing the saturation of the image from the lowest state (becomes a black and white image) by image processing of the controller 111. The “color-out” preset action gradually shifts from a color image to a black-and-white image, contrary to the “color-in” preset action. Note that the time during which the “color-in” process is performed (that is, the time required to shift from the state with the minimum saturation to the state with the maximum saturation) is fixed. The same applies to the “color out” process.

  FIG. 6 shows a moving image in a state where the “depth plus” preset action is executed. The six images displayed in FIG. 6 are extracted from the moving image obtained by executing the “depth plus” preset action, and are shown on the lower side from the state of the image shown on the upper side. It shows that the image is gradually shifted to the image state. As shown in FIG. 6, when the “depth plus” preset action is executed, the movie to be shot has a shallow depth of field at first, and the depth of field gradually increases as time passes. Transition to a deep state. The “depth plus” preset action drives the third stepping motor 223 to gradually reduce the aperture of the aperture adjustment ring 213 and gradually increase the sensitivity of the image sensor 121 (received by image processing). This is realized by amplifying the received signal. Note that, instead of increasing the sensitivity of the image sensor 121, the same effect can be obtained by gradually increasing the luminance value of the image by image processing, gradually decreasing the shutter speed, or using both in combination. In contrast to the “depth plus” preset action, the “depth minus” preset action gradually shifts from a deep depth of field to a shallow depth of field. Note that the time during which the “depth plus” process is performed (that is, the time required to shift from the shallowest subject depth to the deepest state) is fixed. The same applies to the “depth minus” process.

  When the custom action selection button B12 is selected by a touch panel operation on the action selection screen of FIG. 2, the end point setting screen (1) shown in FIG.

  As shown in FIG. 7, the end point setting screen (1) includes an initial state (BEFORE) when the action is started and a final state (AFTER) when the action is ended (FOCUS), zoom (ZOOM). , Sliders LB and LA for setting the aperture value (Av.), The sensitivity and saturation of the image sensor 121 are displayed. The sliders LB and LA for setting the in-focus distance, the zoom, and the aperture value are designed to imitate the focus position adjustment ring 211, the zoom adjustment ring 212, and the aperture adjustment ring 213 of the lens unit 200. By operating the touch panel on the custom action setting screen (for example, dragging the slider LB or LA displayed on the touch panel monitor 141), the focal length, zoom, and zoom in the initial state (BEFORE) and the final state (AFTER) The aperture value, the sensitivity and saturation of the image sensor 121 can be set. In the end point setting screen (1), the sliders LB and LA are surrounded by frames FB and FA to indicate that both the sliders LB and LA can be edited.

  In addition, a pull-down menu P34 for setting the execution time of the action function is displayed on the end point setting screen (1). The user of the digital camera 1 can operate the pull-down menu P34 to specify the time (seconds) for executing the action.

  Note that the end point setting screen (1) is also called when the preset action selection screen of FIG. 3 is selected by selecting one of the preset action buttons B21a to B24b by touch panel operation and then operating the custom action button B25. It has become. In this case, the display contents of the initial state and final state of the focus distance, zoom, aperture value, sensitivity and saturation of the image sensor 121 are the values in the initial state and final state of each shooting parameter in the selected preset action. Is set.

  The “focus in” processing corresponding to the preset action button B22a in FIG. 3 detects the distance (focusing distance) to the main subject immediately before shooting (autofocus operation), and sets the distance sufficiently away from this focusing distance. The initial state and focus distance setting are the final states. Similarly, the “focus out” process corresponding to the preset action button B22b in FIG. 3 detects the distance to the main subject immediately before shooting, and sets the focus distance setting in the initial state, a distance setting sufficiently away from the focus distance. Is the final state. Therefore, when the custom action button B25 is operated after selecting the preset action buttons B22a and B22b, the distance to the main subject is first detected by the autofocus operation. When the preset action button B22a is selected, the detected distance to the main subject is set to the final state (slider LA), and the initial state (slider LB) has an infinite distance or the shortest shooting distance. Set automatically. On the other hand, when the preset action button B22b is selected, the detected distance to the main subject is set to the initial state (slider LB), and the final state (slider LA) has an infinite distance or the shortest shooting distance. Set automatically. Then, while looking at the optical viewfinder (not shown) of the camera, drag the slider LA in the case of the preset action button B22a and drag the slider LB in the case of the preset action button B22b (or adjust the rotation of the focal position adjustment ring 211). In this way, the value of the final state or the initial state can be adjusted.

  In addition, when one of the preset action buttons B21a to B24b is selected by touch panel operation on the preset action selection screen in FIG. 3 and then the custom action button B25 is operated, the initial value of the time specified in the pull-down menu P34 Is the execution time of the selected preset action.

  Then, by operating the sliders LB and LA and the pull-down menu P34 from this state, the selected preset action and the relative change with time of each shooting parameter (that is, the shape of the graph G described later) are not changed. The values of the initial state and the final state, and the execution time are changed. For example, when a function p (t) indicates a time-dependent change of a shooting parameter in the preset action, a function p ′ (t) indicating a time-dependent change of the shooting parameter changed by operating the sliders LB and LA and the pull-down menu P34. ) Is calculated based on the following Equation 1.

  In the above equation 1, PB is the initial value of the shooting parameter specified by the slider LB, PA is the initial value of the shooting parameter specified by the slider LA, and T is the selected preset action. The execution time T ′ is the action execution time set in the pull-down menu P34.

  As shown in FIG. 7, a manual operation button B31, a screen switching button B32, and a completion button B33 are displayed on the end point setting screen (1).

  When the manual operation button B31 is operated by touch panel operation on the end point setting screen (1) in FIG. 7, the end point setting screen (2) shown in FIG. 8 is displayed on the touch panel monitor 141. The screen configuration of the end point setting screen (2) is substantially the same as that of the end point setting screen (1) in FIG. 7, and shows the focal length, zoom, aperture value, sensitivity and saturation of the image sensor 121 in the initial state and final state. Although the sliders LB and LA are displayed, the manual operation button B31, the screen switching button B32, and the completion button B33 are not displayed, and a stop button B35 is displayed instead. In the end point setting screen (2), the slider LB cannot be operated, and the focal length, zoom, and aperture value of the slider LA cannot be operated. In the endpoint setting screen (2), the focal length, zoom, aperture value, sensitivity and saturation of the image sensor 121 in the initial state (BEFORE) are the values when the manual operation button B31 is operated on the endpoint setting screen (1). The setting value is fixed.

  In the end point setting screen (2), the focus position adjustment ring 211, the zoom adjustment ring 212, the aperture adjustment ring 213, and the slider LA displayed on the touch panel monitor 141 of the lens unit 200 are operated, and the focus when the action is executed. The distance, zoom, aperture value, sensitivity of the image sensor 121, and changes in saturation are recorded. Completion of the recording is performed by operating the stop button B35 displayed on the end point setting screen (2). When the stop button B35 is operated to record the focal length, the zoom, the aperture value, the sensitivity of the image sensor 121, and the change in saturation when the action is executed, the touch panel monitor 141 displays the end point setting screen (1 ) Is displayed again. Note that, in the end point setting screen (2), the frame FB is not displayed and the frame FA is also a slider to clearly show that the initial zoom, aperture value, sensitivity and saturation of the image sensor 121 cannot be set. Only the slider for adjusting the sensitivity and saturation of the image sensor 121 in LA is covered. Note that the values set by operating the slider LB on the end point setting screen (1) in FIG. 7 are used as they are as the initial values of the operation parameters on the end point setting screen (2).

  When the screen switching button B32 is operated on the end point setting screen (1) in FIG. 7, the operation setting screen (1) shown in FIG. 9 or 10 is displayed on the touch panel monitor 141.

  As shown in FIGS. 9 and 10, the operation setting screen (1) has a graph G showing temporal changes in shooting parameters such as focal length, zoom, aperture value, sensitivity and saturation of the image sensor 121 during action execution. Is displayed. This graph G is a graph set on the end point setting screen (1) or (2) or the operation setting screen (2) described later. When the operation setting screen (1) is displayed after the initial value and final value of the focal length, zoom, aperture value, sensitivity and saturation of the image sensor 121 are set on the end point setting screen (1), as shown in FIG. In addition, for each item of the focal length, zoom, aperture value, sensitivity of the image sensor 121, and saturation, a line indicating a change in the value of each item at the time of executing the action is displayed one by one. On the other hand, when the focal length, the zoom, the aperture value, the sensitivity of the image sensor 121 and the variation of the saturation are recorded on the end point setting screen (2) or the operation setting screen (2), as shown in FIG. Two lines showing fluctuations are displayed. One of the lines is recorded on the end point setting screen (2) or the operation setting screen (2), and the other of the lines is an idealized (described later) of the recorded line.

  In the operation setting screen (1) of FIG. 9, a graph G showing the temporal variation of the focal length, zoom, aperture value, sensitivity of the image sensor 121 and saturation set in the end point setting screen (1) is displayed. . As described above, the end point setting screen (1) is used to set the initial value and the final value of the focal length, zoom, aperture value, sensitivity of the image sensor 121, and saturation. In the case where the graph is displayed by operating the custom action selection button B12 on the action selection screen (FIG. 2), the graph G displayed on the operation setting screen (1) is linear from the initial value to the final value. It has changed. On the other hand, when the end point setting screen (1) is called from the preset action selection screen (FIG. 3), the graph G displayed on the operation setting screen (1) is the function calculated by the above equation (1). The graph corresponds to p ′ (t).

  In the operation setting screen (1) of FIG. 9, the operation time of the touch panel monitor 141 is changed to the time when the focal length, zoom, aperture value, sensitivity and saturation of the image sensor 121 start to change from the initial values, and the final value. The time to reach can be set. Specifically, in the graph G displayed on the operation setting screen (1), the finger f is placed in a portion where each value starts to fluctuate from the initial value or reaches the final value (solid line portion in the figure), and the time axis is left as it is. By dragging in the direction, it is possible to move the time for starting the fluctuation from the initial value or the time for reaching the final value (the broken line portion in the figure).

  In the operation setting screen (1) of FIG. 10, the shooting parameters such as the focal length, the zoom, the aperture value, the sensitivity of the image sensor 121, and the saturation recorded on the end point setting screen (2) or the operation setting screen (2) are displayed. A graph G on which a line indicating a change (a chain line portion in the figure) and a line that idealizes the recorded change (a solid line part in the figure) is displayed. In FIG. 10, the recorded value fluctuation is indicated by a one-dot chain line, and the idealized value fluctuation is indicated by a solid line, but in reality, both are solid lines of different colors. Note that “idealization” in the present embodiment is a smoothing process for recorded values, and three types of “value increases linearly”, “value decreases linearly”, and “value does not fluctuate”. The shape is approximated by a combination of lines.

  In the operation setting screen (1) in FIG. 10, the focal length, zoom, aperture value, sensitivity of the image sensor 121, and the saturation at the idealized values are obtained by operating the touch panel monitor 141 similar to the operation setting screen (1) in FIG. The variation of each degree can be adjusted. Specifically, in the idealized value line displayed on the operation setting screen (1), the point where the value is discontinuous (that is, the region where the value does not change and the value linearly changes). The point p is moved in the time axis direction by placing the finger f on the boundary p) (solid line portion in the figure) and dragging in the time axis direction as it is, and the shape of the ideal fluctuation line of the value Can be adjusted.

  Also, as shown in FIGS. 9 and 10, a manual operation button B41, a screen switching button B42, and a completion button B43 are displayed on the operation setting screen (1).

  When the manual operation button B41 is operated by a touch panel operation on the operation setting screen (1) of FIG. 9 or FIG. 10, the operation setting screen (2) shown in FIG. The screen configuration of the operation setting screen (2) is substantially the same as that of the operation setting screen (1) of FIG. 9 or FIG. 10, but the manual operation button B41, the screen switching button B42 and the completion button B43 are not displayed. Instead, a stop button B51 is displayed. Further, sliders L52 and L53 for changing the sensitivity and saturation of the image sensor 121 are displayed on the operation setting screen (2). In the operation setting screen (2), the focal length, zoom, aperture value, sensitivity and saturation of the image sensor 121 in the initial state (BEFORE) are determined by operating the manual operation button B21 on the operation setting screen (1). The setting value at the time is fixed.

  In the operation setting screen (2), when the action is executed by operating the focus position adjustment ring 211, the zoom adjustment ring 212, the aperture adjustment ring 213, and the sliders L52 and L53 displayed on the touch panel monitor 141 of the lens unit 200. The focal length, zoom, aperture value, sensitivity of the image sensor 121 and changes in saturation are recorded. Completion of the recording is performed by operating the stop button B51 displayed on the end point setting screen (2). In addition, as shown in FIG. 10, during recording of the focal length, zoom, aperture value, sensitivity of the image sensor 121, and saturation variation during execution of the action, the variation in the above values is displayed as a graph. When the stop button B51 is operated to complete the recording of the focal length, zoom, aperture value, sensitivity of the image sensor 121, and variation in saturation when the action is executed, the controller 111 performs idealization of the graph and displays on the touch panel monitor 141. The operation setting screen (1) of FIG. 10 is displayed.

  When the screen switching button B42 is operated on the operation setting screen (1) of FIG. 9 or FIG. 10, the end point setting screen (1) shown in FIG.

  Further, when the completion button B33 in the end point setting screen (1) in FIG. 7 or the completion button B43 in FIG. 9 or 10 is operated and then the release switch 132 (FIG. 1) of the camera is pressed, as set. In addition, moving images are shot while the focal length, zoom, aperture value, sensitivity and saturation of the image sensor 121 vary. In addition, when the setting of the above-described value variation is performed on the operation setting screen (2) in FIG. 11, whether the recorded value variation (one-dot chain line portion in FIG. 10) is followed before shooting of the moving image is started, It may be configured to select whether to follow an idealized value fluctuation (solid line portion in FIG. 10).

  The operation flow of the digital camera 1 of the present embodiment described above will be described with reference to a flowchart of a routine executed by the controller 111. FIG. 12 is a flowchart of a preset action selection routine that is executed when the action selection button B11 for executing a preset action is operated on the action selection screen of FIG.

  When this routine starts, step S1 is executed. In step S1, the controller 111 causes the touch panel monitor 141 to display the preset action selection screen shown in FIG. Next, the process proceeds to step S2.

  In step S <b> 2, an input operation on the touch panel monitor 141 from the operator of the digital camera 1 is received.

  If the operation input in step S2 is to operate any of the preset action buttons B21a to B24b (S2: preset action button), the process proceeds to step S3.

  In step S3, the controller 111 incorporates temporal change data of shooting parameters (focal length, zoom, aperture value, sensitivity and saturation of the image sensor 121) corresponding to the operated preset action buttons B21a to B24b (not shown). The data is read from storage (flash memory or the like) and stored in the memory of the controller 111. Next, the process returns to step S2.

  If the operation input in step S2 is to operate the completion button B26 (S2: completion button), the process proceeds to step S4.

  In step S4, the controller 111 checks whether or not the shooting parameter aging data is stored in the memory. If no time-varying data is stored in the memory (S4: NO), it means that the preset action buttons B21a to B24b have not yet been selected, so the process returns to step S2 and the input operation of the touch panel monitor 141 is performed again. Accept. On the other hand, if it is confirmed in step S4 that the temporal change data is stored in the memory of the controller 111 (S4: YES), the process proceeds to step S5.

  In step S5, an instruction to execute a shooting screen calling routine for shooting based on the temporal change data is given, and then this routine ends. When this routine is completed through step S5, the above-described shooting screen is displayed, and by pressing the release switch 132, shooting based on the temporal change data is started. In this embodiment, when photographing of the preset action is completed based on the above-described time-change data, the time-change data stored in the memory of the controller 111 is erased, but the time-change data is retained, It is also possible to configure so that repeated photographing can be performed with the same time-varying data. In that case, for example, a button for ending the shooting of the preset action is displayed in the shooting screen.

  If the operation input in step S2 is to operate the custom action button B25 (S2: custom action button), the process proceeds to step S6. In step S6, the controller 111 checks whether or not the shooting parameter aging data is stored in the memory. If no time-varying data is stored in the memory (S6: NO), it means that the preset action buttons B21a to B24b have not yet been selected, so the process returns to step S2 and the input operation of the touch panel monitor 141 is performed again. Accept. On the other hand, in step S6, when it is confirmed that the temporal change data is stored in the memory of the controller 111 (S6: YES), the process proceeds to step S7.

  In step S7, an instruction to execute the calling routine on the end point setting screen (1) in FIG. 7 is given, and then this routine ends. When this routine is finished through step S7, a custom action setting routine (1) described later is subsequently executed.

  Next, the custom action setting routine (1) will be described. FIG. 13 is a flowchart of the custom action setting routine (1). In this routine, the action selection button B12 for executing the custom action is operated on the action selection screen in FIG. 2, or the preset action selection routine in FIG. 12 is terminated through step S7 (that is, the preset action in FIG. 3). On the selection screen, the custom action button B25 is operated after the preset action selection buttons B21a to B24b are operated) or the custom action setting routine (2) of FIG. 111 is executed.

  When this routine starts, step S11 is executed. In step S <b> 11, the controller 111 displays the end point setting screen (1) in FIG. 7 on the touch panel monitor 141. Next, the process proceeds to step S12.

  In step S <b> 12, the controller 111 confirms whether or not the operation parameter change data is stored in the built-in memory. If the temporal change data is stored (S12: YES), the process proceeds to step S15. If no temporal change data is stored (S12: NO), the process proceeds to step S14.

  In step S14, time-change data is generated. Specifically, based on the initial state and final state values of the operation parameters set in advance and the value of the time when the action is executed, the operation parameters of the initial state as shown by the solid line in FIG. Temporal change data that linearly connects the value and the value of the operation parameter in the final state is generated and stored in the memory of the controller 111. Next, the process proceeds to step S15.

  In step S <b> 15, an input operation on the touch panel monitor 141 from the operator of the digital camera 1 is received.

  If the operation input in step S15 is to operate the slider LB, LA or the pull-down menu P34 (S15: slider or menu), the process proceeds to step S16.

  In step S16, the time-change data stored in the memory of the controller 111 is changed based on the above equation (1). Next, the process returns to step S15.

  If the operation input in step S15 is to operate the manual operation button B31 (S15: manual operation button), the process proceeds to step S18.

In step S18, the initial value of the operation parameter set by the slider LB is overwritten and stored in the memory of the controller 111. Further, the controller 111 instructs the execution of the calling routine on the end point setting screen (2), and then ends this routine. When this routine is finished through step S18, a custom action setting routine (2) described later is subsequently executed.

  If the operation input in step S15 is to operate the completion button B33 (S15: completion button), the process proceeds to step S19.

  In step S19, an instruction to execute a shooting screen calling routine for shooting based on the temporal change data is given, and then this routine ends. When this routine is completed through step S19, the above-described shooting screen is displayed, and by pressing the release switch 132, shooting based on the temporal change data is started. In this embodiment, when the preset action shooting is completed based on the above-described time-change data, the time-change data stored in the memory of the controller 111 is deleted, but the time-change data is retained. In addition, it is possible to configure so that repeated photographing can be performed with the same time-varying data. In that case, for example, a button for ending the shooting of the preset action is displayed in the shooting screen.

  If the operation input in step S15 is the screen switching button B32 (S15, screen switching button), the process proceeds to step S20.

  In step S20, after instructing execution of the calling routine on the operation setting screen (1), this routine is terminated. When this routine is completed through step S20, a custom action setting routine (3) described later is subsequently executed.

  As described above, by executing this routine, it is possible to change the operation parameters in the initial state and the final state and the time required for executing the action.

  Next, the custom action setting routine (2) will be described. FIG. 14 is a flowchart of the custom action setting routine (2). This routine is executed by the controller 111 of the digital camera 1 when the manual operation button B31 is operated on the end point setting screen (1) in FIG.

  When this routine starts, step S31 is executed. In step S31, the controller 111 sets the set values of the focus position adjustment ring 211, zoom adjustment ring 212, and aperture adjustment ring 213 of the lens unit 200 in the memory of the controller 111 in step S18 of the custom action setting routine (1) in FIG. Each ring 211-213 is moved so that it may become a memorized value. Next, the process proceeds to step S33.

  In step S33, the controller 111 causes the touch panel monitor 141 to display the end point setting screen (2) of FIG. Note that the value of the operation parameter set in the slider LB on the end point setting screen (2) is the value of the initial operation parameter stored in the memory of the controller 111 in step S18 of the custom action setting routine (1) in FIG. A value is used. Next, the process proceeds to step S34.

  In step S34, it waits for a fixed time (about 0.1 second). Note that while the standby in step S34 is being performed, changes in operation parameters due to operations of the rings 211 to 213 and the slider LA are sequentially recorded. Next, the process proceeds to step S35.

  In step S35, the temporal change data is updated based on the change value of the operation parameter recorded in step S34. At this time, the display content of the slider LA is also changed to the value of the operation parameter after the change. Next, the process proceeds to step S36.

  In step S36, it is confirmed whether or not the stop button B35 has been operated while step S34 is being executed. If the stop button B35 has been operated (S36: YES), the process proceeds to step S37. On the other hand, if the stop button B35 has not been operated yet (S36: NO), the process returns to step S34.

  As described above, by repeating the loop of steps S34 to S36, the temporal change data (that is, the change of the operation parameter due to the operation of the rings 211 to 213 and the slider LA) is recorded.

  In step S37, an instruction to execute the calling routine on the end point setting screen (1) in FIG. 7 is given, and then this routine ends. When this routine ends, the custom action setting routine (1) is executed again from the first step S11.

  Next, the custom action setting routine (3) will be described. FIG. 15 is a flowchart of the custom action setting routine (3). In this routine, the controller 111 of the digital camera 1 is operated when the screen switching button B32 is operated on the end point setting screen (1) of FIG. 7 or when the end button B51 of the moving image setting screen (2) of FIG. 11 is operated. To be executed by.

  When this routine starts, step S42 is executed. In step S42, the controller 111 causes the touch panel monitor 141 to display the operation setting screen (1) in FIG. 10 or the operation setting screen (2) in FIG. Next, the process proceeds to step S43.

  In step S <b> 43, the controller 111 generates a graph G on which a diagram showing the change over time of the operation parameter is displayed from the time change data stored in the memory, and causes the touch panel monitor 141 to display the graph G. Next, the process proceeds to step S44.

  In step S44, it is determined whether it is necessary to idealize the temporal change data of the operation parameters. That is, if the time-varying data of the operation parameter is input by the manual operation of FIG. 9 or FIG. 10, it is determined that the time-varying data needs to be idealized (S45: YES), and the process proceeds to step S45. . On the other hand, if the time-varying data is obtained without performing the manual operation of FIG. 9 or FIG. 10, it is determined that it is not necessary to idealize the time-varying data (S44: NO), and the process proceeds to step S46.

  In step S45, the controller 111 generates idealized temporal change data from the temporal change data stored in the memory, stores this in the memory, and also shows a diagram showing the temporal change of the idealized operation parameter. Is superimposed and drawn on the graph G. Next, the process proceeds to step S46.

  In step S46, an input operation on touch panel 141 is accepted.

  When the operation accepted in step S46 is a drag operation of the graph G (S46: graph drag), the process proceeds to step S47.

  In step S47, the content of the temporal change data (or idealized temporal change data if there is ideal temporal change data) is changed based on the drag operation. Next, the process proceeds to step S48.

  In step S48, the graph G is redrawn based on the temporal change data changed in step S47. Next, the process returns to step S46, and another input is accepted.

  When the operation accepted in step S46 is an operation of the manual operation button B41 (S46: manual operation button), the process proceeds to step S50.

  In step S50, the controller 111 stores the initial value of the operation parameter of the temporal change data in the memory, and then issues an instruction to execute the calling routine on the operation setting screen (2) in FIG. Exit. When this routine is finished through step S50, a custom action setting routine (4) described later is executed.

  If the operation accepted in step S46 is the operation of the completion button B43 (S46: completion button), the process proceeds to step S51.

  In step S51, an instruction to execute a shooting screen calling routine for shooting based on the temporal change data is given, and then this routine ends. When this routine is completed through step S51, the above-described shooting screen is displayed, and by pressing the release switch 132, shooting based on the temporal change data is started. It should be noted that when the preset action shooting is completed based on the above time-varying data, the time-varying data stored in the memory of the controller 111 is erased, but the time-varying data is retained and the same time-varying data is stored. It is also possible to configure to be able to repeatedly shoot with data. In that case, for example, a button for ending the shooting of the preset action is displayed in the shooting screen.

  When the operation accepted in step S46 is the operation of the screen switching button B42 (S46: screen switching button), the process proceeds to step S52.

  In step S52, an instruction to execute a routine for calling the end point setting screen (1) (custom action setting routine (1)) is given, and then this routine ends. When this routine is completed through step S20, the custom action setting routine (1) shown in FIG. 13 is subsequently executed.

  As described above, by executing this routine, it is possible to adjust the time-varying data of the operation parameter by the drag operation.

  Next, the custom action setting routine (4) will be described. FIG. 16 is a flowchart of the custom action setting routine (4). This routine is executed by the controller 111 of the digital camera 1 when the manual operation button B41 is operated on the end point setting screen (1) of FIG. 9 or FIG.

  When this routine starts, step S61 is executed. In step S61, the controller 111 sets the set values of the focus position adjustment ring 211, the zoom adjustment ring 212, and the aperture adjustment ring 213 of the lens unit 200 in the memory of the controller 111 in step S50 of the custom action setting routine (3) in FIG. Each ring 211-213 is moved so that it may become a memorized value. Next, the process proceeds to step S63.

  In step S63, the controller 111 causes the touch panel monitor 141 to display the operation setting screen (2) of FIG. The initial values of the operation parameters of the graph G and the sliders L52 and L53 on the operation setting screen (2) are the initial operation parameter values stored in the memory of the controller 111 in step S50 of the custom action setting routine (3). A value is used. Next, the process proceeds to step S64.

  In step S64, the system waits for a predetermined time (about 0.1 second). Note that while the standby in step S64 is being performed, changes in operation parameters due to operations of the rings 211 to 213 and the sliders L52 and L53 are sequentially recorded. Next, the process proceeds to step S65.

  In step S65, the temporal change data is updated based on the change value of the operation parameter recorded in step S64. At this time, the display contents of the sliders L52 and L53 and the graph G are also changed to the changed operation parameter values. Next, the process proceeds to step S66.

  In step S66, it is confirmed whether or not the stop button B51 has been operated while step S64 is being executed. If the stop button B51 has been operated (S66: YES), the process proceeds to step S67. On the other hand, if the stop button B51 has not been operated yet (S66: NO), the process returns to step S64.

  As described above, by repeating the loop of steps S64 to S66, the temporal change data (that is, the change of the operation parameter due to the operation of the rings 211 to 213 and the sliders L52 and L53) is recorded.

  In step S66, after instructing execution of the calling routine on the operation setting screen (1) of FIG. 9 or FIG. 10, this routine is terminated. When this routine ends, the custom action setting routine (3) is executed again from the first step S42.

  As described above, the various functions of the digital camera 1 described above are realized by executing the routines of FIGS.

  In the present embodiment, the sensitivity of the image sensor 121 is adjusted on the end point setting screens (1) and (2) and the moving image setting screens (1) and (2). It is not limited to the configuration, and instead of the sensitivity of the image sensor 121, other shooting parameters that change the brightness of the image without changing the aperture value, for example, the brightness value and the shutter speed during image processing can be adjusted. It is good also as a simple structure.
