The user can confirm the input of the display frame selected and displayed by pressing the OK button 103b of the multi-selector dial 103 at the position of the display frame selected and displayed.

  In step S <b> 102, the system control unit 101 acquires an operation input for image selection by the command dial 102 and the multi-selector dial 103 as described above. In step S103, the system control unit 101 determines whether a moving image file has been selected. If YES in the determination in step S103, the image processing unit 115 reproduces and displays the moving image of the selected moving image file on the liquid crystal monitor 17 in step S104. Subsequently, in step S105, the system control unit 101 determines whether or not the video editing mode has been switched. Switching to the moving image editing mode is performed when the user operates the command dial 102 during moving image reproduction.

  If “NO” in the determination in step S105, the system control unit 101 proceeds to step S106, and determines whether or not the reproduction of the moving image has been completed (including stoppage during reproduction by a user operation input). If NO in step S106, the system control unit 101 returns to step S104. If YES in step S106, the process returns to step S101, and the image selection screen 200 is displayed on the liquid crystal monitor 17.

  On the other hand, if “YES” in the determination in step S105, the image processing unit 115 proceeds to step S107, shifts to the moving image editing mode, and displays a moving image frame advance image. Subsequently, in step S <b> 108, the system control unit 101 acquires an operation input of the editing range by the command dial 102 and the multi-selector dial 103. Here, the operation input of the editing range will be described.

  FIG. 6 is an explanatory diagram when a frame advance image of a moving image is displayed on the liquid crystal monitor 17. In the moving image shooting mode, an image is recorded at 30 frames per second. Therefore, a 10-second moving image is composed of 300 frames of still images. When the image processing unit 115 shifts to the moving image editing mode, the first still image of the first frame among the plurality of still images constituting the moving image is displayed on the liquid crystal monitor 17. When the user rotates the command dial 102 while a still image is displayed, the still image is frame-advanced in the rotation direction.

  By rotating the command dial 102, the user can view the still image in the order of frame 1, frame 2, frame 3,. Then, the user can designate the position of the still image where the OK button 103b is pressed as the editing start position by pressing the OK button 103b of the multi-selector dial 103 at the position of the first still image to be extracted. . FIG. 6 shows a case where the OK button 103b is pressed in the still image of frame 2.

  After designating the edit start position, the user further rotates the command dial 102 and presses the OK button 103b at the position of the last still image of the still image to be extracted, whereby the position of the still image where the OK button 103b is pressed. Can be designated as the editing end position. FIG. 6 shows a case where the OK button 103b is pressed in the still image of the frame 6. Note that only one frame may be extracted as a still image. In this case, the OK button 103b is pressed twice at the same still image position.

  When the user designates the editing end position, the image processing unit 115 selects a still image included in the editing range of the designated frame 2 to frame 6 from a plurality (for example, 1 to 300) of still images constituting the moving image. Are extracted and generated as still image data. For example, when the moving image data is compressed by Motion JPEG, each frame extracted from the moving image data is generated as JPEG still image data.

  Further, when the editing end position is designated, the image processing unit 115 displays the number of still image frames included in the editing range on the screen of the liquid crystal monitor 17. In FIG. 6, a number “5/300” indicating the number of extracted frames is displayed on the still image of frame 6 that is the editing end position. In this example, 5 frames out of 300 frames are the number of frames extracted by editing. Thereby, the user can confirm on the screen the number of still image frames included in the editing range designated by the user.

  In step S108 of FIG. 4, after obtaining the operation input of the editing range as described above, in step S109, the image processing unit 115 determines the number of frames of the still image included in the specified editing range (hereinafter, the number of editing frames). Is determined to be less than a preset reference frame number. The reference frame number is a threshold value used for determining whether a still image extracted from a plurality of still images is recorded as a still image or a moving image.

  If the determination in step S109 is YES, the image processing unit 115 proceeds to step S110 and extracts a still image included in the designated editing range. In step S111, the image processing unit 115 records the extracted still image data of the still image on the recording medium 60 as a still image file. Note that still image data of still images extracted from a plurality of still images is generated as a still image file compressed in a predetermined still image compression format. At this time, a specific file name is added so that it can be distinguished from other captured still image files.

  If NO in step S109, the image processing unit 115 proceeds to step S112, and extracts a still image included in the designated editing range. In step S113, the image processing unit 115 records the moving image moving image data constituted by the extracted still image as a moving image file on the recording medium 60. Note that moving image moving image data composed of still images extracted from a plurality of still images is generated as a moving image file compressed in a predetermined moving image compression format. At this time, a specific file name is added so that it can be distinguished from other captured video files.

  The image processing unit 115 extracts the still image included in the designated editing range and records it as a still image file in the process of step S110, as shown in FIG. The message frame 211 “Do you want to record as a still image file?” Is displayed on the editing screen 210. Further, the image processing unit 115 extracts a still image included in the designated editing range in the process of step S112, and before recording a moving image composed of the still image as a moving image file (FIG. 7 ( As shown in B), a message frame 212 “Do you want to record as a moving image file?” Is displayed on the editing screen 210 of the liquid crystal monitor 17. Thereby, the user can confirm whether a still image included in the editing range designated by the user is recorded as a still image file or a moving image file.

  7A and 7B, the user can record a still image file or a moving image file on the recording medium 60 by pressing the OK button 103b. Further, by pressing the play button 119, the extraction of the still image can be canceled. When the still image extraction is canceled, the screen returns to the image selection screen 200 shown in FIG. 5 or the frame advance image display shown in FIG.

  On the other hand, if the determination in step S103 is NO, the image processing unit 115 proceeds to step S114 and determines whether a still image file has been selected. If YES in step S114, the image processing unit 115 proceeds to step S115, and displays the still image of the selected still image file on the liquid crystal monitor 17. Thereafter, the process returns to step S102, and an operation input for image selection is acquired. If NO in step S114, that is, if an operation input other than image selection is acquired, the system control unit 101 proceeds to step S116, executes other processes, and ends the process of this routine.

  Next, the change of the reference frame number will be described. FIG. 8 is an explanatory diagram showing an input screen for setting the reference frame number change. The input screen shown in FIG. 8 is displayed on the liquid crystal monitor 17. On the input screen 220, an area 221 for setting the reference frame number is displayed. In the initial state, an initial value (in this case, “5”) is displayed in the area 221. This initial value is a numerical value set at the time of shipment, and can be changed by a user operation input. In order to change the number of reference frames, the displayed numerical value can be increased or decreased by pressing a vertical arrow mark 103a of a multi-selector dial 103 (FIG. 3) provided on the back of the camera 1 a predetermined number of times. . When the desired numerical value is input, the input numerical value can be set (registered) by pressing the OK button 103b of the multi-selector dial 103. The numerical value of the reference frame number set on the input screen 220 is stored in a nonvolatile memory (not shown) by the system control unit 101.

According to the said 1st Embodiment, there exist the following effects.
(1) Since the user can extract a desired still image from the moving image at a time and record it on the recording medium 60, the operability when extracting the still image from the moving image can be improved. .
(2) When the number of editing frames in the editing range designated by the user is less than the reference number of frames, the extracted still image is recorded as a still image file, and thus a short moving image that ends immediately even when played back Is not recorded as a new video file. Therefore, it is possible to prevent a moving image file that is difficult to reuse from being recorded on the recording medium 60. Further, since a message is displayed to record as a still image file, the user can recognize how a still image included in the designated editing range is recorded.

  Next, an embodiment in which the still image file recorded on the recording medium 60 can be further edited will be described. The image processing unit 115 according to the present embodiment functions as a function of the image processing unit when the number of still images included in the designated editing range is less than the reference number of frames. A still image included in the designated editing range is extracted from the image, and the still image is displayed on the liquid crystal monitor 17, and the command dial 102 and the multi-selector dial 103, which are operation input acquisition means, are operated by the user. When an operation input for selecting a specific still image from the still images displayed on the liquid crystal monitor 17 is acquired, the still image selected by the operation input from the still images included in the designated editing range is acquired. A process of extracting an image and recording the still image on the recording medium 60 as a recording destination is executed.

  Further, the image processing unit 115 displays, as a function of the image processing unit, the number of still image frames selected by the user operating the command dial 102 and the multi-selector dial 103 which are operation input acquisition units. Processing to be displayed on a certain liquid crystal monitor 17 is executed.

  FIG. 9 is an explanatory diagram showing an example of a still image file editing screen. The edit screen 230 is displayed when the user selects a desired still image file display frame 201 from the image selection screen 200 (FIG. 5) and performs an operation input for displaying the edit screen by the command dial 102.

  On the edit screen 230, as shown in FIG. 9, six still images extracted from a plurality of still images are displayed in a thumbnail format. In FIG. 9, a still image display frame 231 corresponding to the frames 2 to 6 shown in FIG. 6 is displayed. While viewing the editing screen 230, the user presses the up / down / left / right arrow marks 103a (FIG. 3) of the multi-selector dial 103 to select a desired still image, and presses the OK button 103b at that position to thereby display the still image. The selection can be confirmed. The selected still image is displayed with a thicker outline than the display frame of other still images. FIG. 9 shows a state in which still images corresponding to frame 3, frame 4, and frame 6 are selected and displayed.

  Further, a number “3/5” indicating the number of frames of the selected still image is displayed on the lower right of the editing screen 230. In this example, 3 frames out of 5 frames are selected. Thereby, the user can confirm the number of still images selected by the user on the screen.

  Then, by pressing the play button 119 (FIG. 3) in the state of FIG. 9, only the still image data of the selected still image can be recorded on the recording medium 60. In the example shown in FIG. 9, the still image data of the frames 2 and 5 that are not selected are deleted from the recording medium 60.

According to the said 2nd Embodiment, there exist the following effects.
(6) Since the still image extracted from the moving image can be further edited, only the still image required by the user can be recorded. Therefore, the recording capacity of the recording medium 60 can be used effectively.
(7) Since the number of still image frames selected by the user is displayed on the liquid crystal monitor 17, the user can check the number of still images selected by the user on the screen.
