As one of the operation units 70, a touch panel 70a (see FIG. 1) capable of detecting contact with the display unit 28 is provided. The touch panel 70a and the display section 28 can be configured integrally. For example, the touch panel 70 a is configured such that the light transmittance does not interfere with the display of the display section 28 and is attached to the upper layer of the display surface of the display section 28 . Then, the input coordinates on the touch panel 70a and the display coordinates on the display screen of the display unit 28 are associated with each other. This makes it possible to provide a GUI (graphical user interface) as if the user could directly operate the screen displayed on the display unit 28 . The system control unit 50 performs the following operations on the touch panel 70a. Alternatively, the state can be detected.
- A finger or pen that has not touched the touch panel 70a newly touches the touch panel 70a. That is, the start of touch (hereinafter referred to as Touch-Down).
- The touch panel 70a is in a state of being touched with a finger or a pen (hereinafter referred to as Touch-On).
- Moving while touching the touch panel 70a with a finger or pen (hereinafter referred to as touch-move).
- The finger or pen that has touched the touch panel 70a has been released. That is, the end of touch (hereinafter referred to as touch-up).
A state in which nothing is touched on the touch panel 70a (hereinafter referred to as Touch-Off).

When touchdown is detected, touchon is also detected at the same time. After touchdown, touchon continues to be detected unless touchup is detected. A touch-move is also detected when a touch-on is detected. Even if touch-on is detected, touch-move is not detected if the touch position does not move. After it is detected that all the fingers and pens that have touched have touched up, the touch is turned off.

The system control unit 50 is notified of these operations/states and the coordinates of the position where the finger or pen touches the touch panel 70a through the internal bus. It is determined whether such an operation (touch operation) has been performed. As for the touch move, the moving direction of the finger or pen moving on the touch panel 70a can also be determined for each vertical component/horizontal component on the touch panel 70a based on the change in the position coordinates. If it is detected that the touch-move has been performed for a predetermined distance or more, it is determined that the slide operation has been performed. An operation of touching a touch panel with a finger and quickly moving it by a certain distance and then releasing it is called a flick. A flick is, in other words, an operation of quickly tracing the touch panel 70a as if flicking it with a finger. It can be determined that a flick has been performed when a touch-move of a predetermined distance or more at a predetermined speed or more is detected, and a touch-up is detected as it is (it can be determined that a flick has occurred following a slide operation).

Further, a touch operation of simultaneously touching a plurality of points (for example, two points) to bring the touch positions closer to each other is called pinch-in, and a touch operation of moving the touch positions away from each other is called pinch-out. Pinch-out and pinch-in are collectively called pinch operation (or simply pinch).

The touch panel 70a may be any one of various types of touch panels such as a resistive film type, a capacitance type, a surface acoustic wave type, an infrared type, an electromagnetic induction type, an image recognition type, an optical sensor type, and the like. good. Depending on the method, there is a method of detecting that there is a touch when there is contact with the touch panel, and a method of detecting that there is a touch when there is an approach of a finger or pen to the touch panel.

When editing is selected, the transition to the video editing screen is made as it is. FIGS. 10A to 10D are diagrams showing examples of moving image editing screens. The displayed shortcut items are changed depending on the presence or absence of the front cut requirement flag and the presence or absence of the rear cut requirement flag. As will be described later with reference to FIG. 10, if there is a front-cut requirement flag, an item for front-cutting is displayed, and if there is a rear-cutting requirement flag, an item for rear-cutting is displayed. be done.

In S617, the system control unit 50 executes the moving image editing process described with reference to FIG.

A series of flow of moving image editing processing will be described with reference to FIG. 11 . FIG. 11 is a flowchart showing an example of starting editing processing of a moving image, editing a moving image depending on the presence or absence of a pre-clipping requirement flag and a post-clipping requirement flag, and writing to a file in this embodiment.

This process is realized by loading the program recorded in the nonvolatile memory 56 into the system memory 52 and executing it by the system control unit 50 . Note that this process is started when the power of the digital camera 100 is turned on and the process proceeds to S617.

In S1101, the system control unit 50 determines whether or not the moving image to be edited has a pre-cut requirement flag. If there is a pre-cut requirement flag, the process proceeds to S1102; otherwise, the process proceeds to S1106.

In S1102, the system control unit 50 determines whether or not the long second condition is satisfied. If the long second condition is satisfied, the process advances to S1103 to display a long second cut-off icon on the edit screen (Fig. 10(c): 1001C). If the long second condition is not satisfied, the process proceeds to S1104.

In S1104, the system control unit 50 determines whether or not the short second condition is satisfied. If the short-second condition is satisfied, the process advances to S1105 to display a short-second cut-off icon on the edit screen (FIGS. 10A and 10D: 1101A, 1101D). If the short second condition is not satisfied, the process proceeds to S1106. Definitions of long seconds and short seconds will be described later.

In S1106, the system control unit 50 determines whether or not the moving image to be edited has a trailing cut requirement flag. If there is a post-cut requirement flag, the process proceeds to S1107; otherwise, the process proceeds to S1111.

In S1107, the system control unit 50 determines whether or not the long second condition is satisfied. If the long second condition is satisfied, the process advances to S1108 to display a long second cut icon on the edit screen (FIGS. 10B, 10C: 1001B, 1002C). If the long second condition is not satisfied, the process proceeds to S1109.

In S1109, the system control unit 50 determines whether or not the short second condition is satisfied. If the condition for short seconds is satisfied, the process advances to S1110 to display a short second cut icon on the edit screen (FIG. 10A: 1002A). If the condition of short seconds is not satisfied, the process proceeds to S1111.

In the present embodiment, unnecessary parts during video shooting are deleted from the video. It mainly refers to the part where the photographer's preparations for the start or end of shooting are shown. In the case of an instruction to end a moving image, since the digital camera 100 is operated during the shooting of the moving image, the moving image includes the movement from the original position of the user to the position of the digital camera 100 and the instruction to end the shooting. be In the case of a moving image start instruction, the moving image shows how the user approaches the digital camera 100 and issues a moving image shooting start instruction, moves to a desired position, and prepares for shooting. included. In such a case, it is highly likely that the user will delete the beginning or end of the video for a period of time such as 10 seconds or 15 seconds. On the other hand, if the operation is performed using a remote controller, the time required to hide the operated remote controller is about 2 seconds or 5 seconds.

In this way, the time from when the start of photographing is instructed to when the unnecessary image is not actually captured varies depending on the means for starting and stopping photographing. For example, if the digital camera 100 is directly and physically operated to instruct the start/stop of a moving image, the duration is set to long, and if the operation is performed using the remote control, the duration is set to short, and a flag is attached when the image starts or stops. may Depending on the flag, whether to display an item for deleting a long-second moving image or an item for deleting a short-second moving image on the edit screen may be changed.

In S1111, the system control unit 50 determines whether the user has touched the long-second cut-off icon (FIG. 10C: 1101C). is moved by N seconds. If the long second cut-off icon (FIG. 10C: 1101C) has not been touched, the process proceeds to S1113. A long second is a time such as 10 seconds or 15 seconds, for example.

In S1113, the system control unit 50 determines whether the user has touched the short-second cut-off icon (FIGS. 10A and 10D: 1101A, 1101D). Go forward and move the cut-off position of the edit bar by S seconds. If the short second cut-off icon (Fig. 10(a), Fig. 10(d): 1101A, 1101D) has not been touched, the process proceeds to S1115. A short second is, for example, a time such as 2 seconds or 5 seconds.

In S1115, the system control unit 50 determines whether the user has touched the long-second cut-off icon (FIGS. 10B and 10C: 1101B, 1102C). Go forward and move the end cut position of the edit bar by N seconds. If the long-second cut-off icon (Fig. 10(b), Fig. 10(c): 1101B, 1102C) has not been touched, the process proceeds to S1117.

In S1117, the system control unit 50 determines whether or not the user has touched the short-second cut-off icon (FIG. 10A: 1102A). is moved for S seconds. If the short-second cut-off icon (FIG. 10A: 1102A) has not been touched, the process proceeds to S1119.

In S1119, the system control unit 50 determines whether the user has operated either the front cut bar or the rear cut bar for the moving image to be edited. If it is determined that any one of them has been operated, the process proceeds to S1120. In S1120, the system control unit 50 moves the edit bar to the position specified by the user. If neither the front turning bar nor the rear turning bar has been operated, the process proceeds to S1121.

In S1121, the system control unit 50 determines whether or not the user has issued a preview start instruction, and if it is determined that the preview start instruction has been issued, performs preview reproduction of the moving image to be edited. If S1121 is Yes, the process advances to S1122 to perform preview reproduction of the edited moving image. Otherwise, the process proceeds to S1123.

In S1123, the system control unit 50 determines whether or not an instruction to finish editing the moving image to be edited has been issued. If it is determined that an instruction to end editing has been given, the process advances to S1124 to write the edited moving image to a file and save it in the recording medium 200 . If S1123 is No, the process proceeds to S1125.

In S1125, the system control unit 50 determines whether or not to cancel editing of the moving image to be edited. If it is determined to cancel, the editing process of the moving image ends without recording the edited moving image up to that point, otherwise the process returns to S1111.

If cancel is selected on the screen of FIG. 9 immediately after shooting a moving image, the moving image can be edited from the playback screen. Since the front-cut requirement flag or the end-cut requirement flag is stored in a moving image that has not been edited immediately after shooting, guidance such as that shown in FIG. 12A is displayed. By pressing the item 1201A, a video editing screen is displayed, and the video can be edited.

When the item 1201A is pressed, the edit screen of FIG. 10 is displayed on the display unit 28. FIG. A video can be edited regardless of the presence or absence of the front-cut requirement flag and the rear-cut requirement flag. Items for transitioning to the video editing screen are prepared and displayed on the display unit 28 .

1202A in FIG. 12A is a video editing item when there is an item 1201A indicating that there is a front-cut requirement flag and a rear-cut requirement flag; 1201B in FIG. It is a display example of the video editing item when there is no such item. By pressing items 1202A and 1201B, the screen transitions to the moving image editing screen.

With reference to the flowchart of FIG. 13, the flow of processing in the case where a moving image in which the front-cut requirement flag or the rear-cut requirement flag is stored is displayed on the playback screen will be described.

This process is realized by loading the program recorded in the nonvolatile memory 56 into the system memory 52 and executing it by the system control unit 50 . Note that this process is started when the digital camera 100 is powered on and transitions to the playback mode.

In S<b>1301 , the system control unit 50 reads moving image data from the recording medium 200 into the memory 32 .

In S1302, the system control unit 50 causes the display unit 28 to display a representative image of the moving image to be edited.

In S<b>1303 , the system control unit 50 determines whether the moving image data displayed on the display unit 28 has the information of the front cut requirement flag or the rear cut requirement flag. If there is a front cut requirement flag or a rear cut requirement flag, the process proceeds to S1304; otherwise, the process proceeds to S1306.

In S1304, the system control unit 50 causes the display unit 28 to display an editing recommendation guide as shown in FIG. 12(a).

If the system control unit 50 determines in S1305 that the edit item 1201A has been pressed by the user operation, the process advances to S1307. The editing process is as shown in the flow chart of FIG. If the edit item 1201A is not pressed, the process advances to S1306. When a moving image is displayed on the display unit 28, an item 1202A for transitioning to the moving image editing screen is displayed.

If the system control unit 50 determines in S1306 that the item 1202A has been pressed, the process proceeds to S1307, and if it determines that the item 1202A has not been pressed, the process proceeds to S1308. When a moving image is displayed on the display unit 28, the moving image being displayed can be reproduced.

If the system control unit 50 determines in S1308 that the moving image reproduction button has been pressed and a moving image reproduction request has been made, the process proceeds to S1309, and the system control unit 50 causes the display unit 28 to reproduce the moving image. Reproduction of the moving image continues until an operation to stop reproducing the moving image is performed in S1310. If the moving image stop operation is performed, the process returns to S1306. If the video playback instruction is not issued in S1308, the process advances to S1311.

If the system control unit 50 determines in S1311 that there is a request to switch the moving image displayed on the display unit 28, the system control unit 50 expands the next image data from the storage medium 200 to the memory 32 in S1313. An image is displayed on the display unit 28 in S1301.

If the system control unit 50 determines in S1311 that an image switching instruction has not been issued, the process advances to S1312.

If the system control unit 50 determines in S1312 that there is no reproduction end request, the process advances to S1306, and if there is a reproduction end request, the reproduction processing ends.

By performing the processing as described above, it is possible to start actions such as the user's hand being reflected in order to operate the camera or the user's remote control operation when operating the main unit and instructing to shoot a video when taking a selfie. It is possible to easily delete an unnecessary portion of the moving image showing the instruction to end.
