(Recording process of moving image data and still image data)
Next, basic recording processing by the digital camera 100 will be described. The digital camera 100 can record a still image file including still image data and a moving image file including moving image data on the recording medium 108. When a power-on instruction is given by the operation unit 106, the control unit 105 controls each unit to set the digital camera 100 to a recording standby state. In the recording standby state, the imaging unit 101 outputs moving image data, and an image of a subject related to the moving image data from the imaging unit 101 is displayed on the display unit 109.

  The moving image data recording process will be described. In the recording standby state of the digital camera 100, the moving image data recording process is performed by the control unit 105 controlling each unit in response to the input of the moving image data recording instruction from the operation unit 106. The control unit 105 causes the recording / playback unit 107 to generate a new moving image file on the recording medium 108 in response to an instruction to start recording moving image data, and records the moving image data output from the imaging unit 101 in the generated moving image file.

(Recording process when instructed to acquire still image data during video data recording)
FIG. 2 is a flowchart showing recording processing of identification information (flag information) and a moving image file based on an instruction to acquire still image data when an instruction to acquire still image data is instructed during recording of moving image data in the present embodiment. It is. The flowchart of FIG. 2 is stored in the memory 102 when the digital camera 100 is turned on or set to a moving image recording mode in which an instruction to obtain still image data can be issued during recording of moving image data. It starts based on the program that is running. The control unit 105 mounts the recording medium 108 in response to power-on of the digital camera 100 and prepares for recording a file on the recording medium 108.

  In step S <b> 201, the control unit 105 determines whether an instruction to start recording moving image data is input from the operation unit 106. If no instruction to start recording moving image data is input, in step S209, the control unit 105 determines whether the moving image recording mode has been changed to another mode such as a still image recording mode or a reproduction mode, or the power source of the digital camera 100 is Determine if it was turned off. When the mode is changed to another mode or when the power is turned off, this process is terminated. If the mode has not been changed to another mode or the power has not been turned off, the control unit 105 continues the determination in step S201.

  When an instruction to start recording moving image data is input, the control unit 105 instructs the recording / playback unit 107 to open a new moving image file on the recording medium 108 in step S202. In step S203, the control unit 105 causes the signal processing unit 103 to encode the moving image data output from the imaging unit 101, and further records the moving image data in the moving image file of the recording medium 108 opened in step S202 in the recording / playback unit 107. To control.

  In step S <b> 204, the control unit 105 determines whether a still image data acquisition instruction has been input via the operation unit 106. When a still image data acquisition instruction is input, in step S205, the control unit 105 generates identification information based on the still image data acquisition instruction input during recording of moving image data as flag information and stores it in the memory 102. Hold.

  In the present embodiment, the flag information is generated every time a still image data acquisition instruction is input during recording of moving image data. The flag information includes a flag ID and information related to the elapsed time from the start of recording.

  The flag ID is a number given to identify the input acquisition instruction, starting from 0 and incrementing by 1 each time the acquisition instruction is input. As the flag ID, a value obtained by adding 1 to the maximum flag ID among the flag information generated for the moving image file being recorded when an instruction to acquire still image data is input. In the present embodiment, the flag ID uses a number starting from 0 each time recording of moving image data is started. For example, the flag ID is set to a continuous number from the power-on to the power-off of the digital camera 100. It may be given.

  Information relating to the elapsed time from the start of recording is information relating to the timing at which an instruction to acquire still image data is input. For example, the information on the elapsed time from the start of recording may be information on the time measured by a timer (not shown), or obtained by multiplying the elapsed time from the start of recording of moving image data by the frame rate of the moving image data. Alternatively, the number of elapsed frames from the start of recording of moving image data may be used. In the present embodiment, the number of elapsed frames from the start of recording of moving image data corresponding to the timing at which an instruction to acquire still image data is input is used as information related to the elapsed time from the start of recording.

  In step S206, the control unit 105 determines whether or not an instruction to stop recording moving image data is received via the operation unit 106, and continues the processing from step S203 to step S205 until an instruction to stop recording moving image data is received. . In this way, when a still image data acquisition instruction is input a plurality of times during recording of one moving image data, a plurality of flag information corresponding to each still image data acquisition instruction is held in the memory 102.

  When an instruction to stop recording moving image data is received in step S206 (Yes in step S206), the control unit 105 stops recording moving image data in step S207. In step S208, the control unit 105 records the flag information held in the memory 102 in a form to be added to the moving image file, and causes the recording / playback unit 107 to perform the moving image file closing process to perform the moving image data recording process. finish.

  The flag information may be recorded in the header portion of the moving image file that was being recorded when the still image data acquisition instruction was input, or may be recorded on the recording medium 108 as the moving image file management information separately from the moving image file. May be. FIG. 3 shows a schematic diagram of flag information added to the moving image file 301. FIG. 3 shows a case where a still image data acquisition instruction is input three times during recording of the moving image file 301 and flag information 302, 303, 304 is added to the moving image file 301. Flag information 302 corresponding to the first still image data acquisition instruction indicates that a still image data acquisition instruction has been input when the number of frames that have elapsed since the start of moving image data recording is 30.

(Recording process of flag information when instructed to acquire still image data during playback of video data)
FIG. 4 is a flowchart showing a flag information recording process when an instruction to acquire still image data is given during reproduction of moving image data in the present embodiment. The flowchart in FIG. 4 is started based on a program stored in the memory 102 when an instruction to reproduce a moving image file is issued in the reproduction mode by the operation unit 106. In the playback mode, the display unit 109 displays an index screen including a moving image file recorded on the recording medium 108 and a representative image (thumbnail) of a still image file. The processing of this flowchart starts when the user operates the operation unit 106 to select a representative image of a moving image file from the representative images of each file displayed on the display unit 109 and inputs a reproduction instruction for the selected moving image file. Is done.

  In step S401, the control unit 105 controls the recording / reproducing unit 107 to reproduce the moving image data instructed to be reproduced. In step S402, the control unit 105 determines whether a still image data acquisition instruction has been input via the operation unit 106 while moving image data is being reproduced. When a still image data acquisition instruction is input, in step S403, the control unit 105 generates identification information based on the still image data acquisition instruction input during recording of moving image data as flag information and stores it in the memory 102. Hold. The flag information is the same as the flag information recorded during the recording of the moving image data described above. If no still image data acquisition instruction has been input in step S402, the process proceeds to step S404.

  In step S <b> 404, the control unit 105 determines whether an instruction to stop reproduction of moving image data has been received via the operation unit 106, or whether reproduction of moving image data has ended. When the instruction to stop the reproduction of the moving image data has not been received, and when the reproduction of the moving image data has not ended, the process from step S401 to step S403 is performed until the instruction to stop the reproduction of moving image data is received or the reproduction of the moving image data ends. Repeat the process. When the instruction to stop the reproduction of the moving image data is received or when the reproduction of the moving image data ends (Yes in step S404), the control unit 105 stops the reproduction of the moving image data in step S405. In step S406, the control unit 105 records the flag information held in the memory 102 in a form to be added to the reproduced moving image file, and ends the process.

(Recording process of still image data corresponding to flag information)
In the present embodiment, when flag information is added to a moving image file and recorded, the still image data corresponding to the flag information is recorded as a still image file in response to a still image data recording instruction input at an arbitrary timing. It can be recorded on the medium 108. For example, the digital camera 100 has a still image data recording mode corresponding to the flag information.

  When a mode for recording still image data corresponding to flag information is selected, the control unit 105 selects a representative image of a moving image file to which flag information is added from among files recorded on the recording medium 108 as a moving image. Controls display as a file index screen. The user selects a moving image file from the moving image file index screen displayed on the display unit 109 via the operation unit 106.

  Then, the control unit 105 displays the representative image relating to the flag information added to the selected moving image file on the display unit 109 as an index screen of flag information. As a representative image related to the flag information displayed at this time, a reduced icon (thumbnail) of still image data corresponding to a predetermined icon or flag information, a list of flag IDs, or the like can be used. The representative image related to the flag information may be generated by the signal processing unit 103 or the image processing unit 104 and added to the moving image file and recorded together with the flag information when the flag information is added to the moving image file and recorded. . Alternatively, when displaying the flag information index screen on the display unit 109, the signal processing unit 103 or the image processing unit 104 generates a representative image for each flag information, and displays the generated representative image for the flag information on the display unit 109. The control unit 105 may control so as to.

  On the flag information index screen, a representative image related to flag information is selected by the user via the operation unit 106, and the flag information of the selected representative image is determined as flag information for recording still image data on the recording medium 108. . When a still image data recording instruction is input via the operation unit 106, the control unit 105 controls to generate still image data corresponding to the flag information. Specifically, the control unit 105 controls the signal processing unit 103, and the moving image data recorded in the recording medium 108 is recorded in a portion of the moving image data corresponding to the number of frames elapsed from the start of recording of the moving image data included in the flag information. Play from the file and decode. Then, the signal processing unit 103 generates still image data based on a frame corresponding to the number of elapsed frames of flag information from the decoded moving image data.

  Then, the control unit 105 controls the recording / reproducing unit 107 to record the generated still image data on the recording medium 108 with a file name added as a still image file. At this time, the control unit 105 indicates information indicating that the still image file corresponds to the flag information to the metadata of the still image file corresponding to the flag information (for example, the file name or flag ID of the moving image file to which the flag information is added). ) May be recorded.

  In response to recording the still image data corresponding to the flag information on the recording medium 108, in the present embodiment, the control unit 105 displays the recorded information indicating that the still image data has been recorded on the recording medium 108 as flag information. Add to and record. In the case of this configuration, the control unit 105 may display a representative image of a moving image file to which flag information in which recorded information of still image data is not recorded is added on the above-described moving image file index screen. . Alternatively, the index screen for movie files displays representative images of all movie files with flag information added, and identifies movie files with flag information to which recorded information of still image data is not recorded You may make it display as possible.

  In addition, in the flag information index screen described above, only representative images related to flag information in which recorded information of still image data is not recorded among flag information added to the moving image file selected on the moving image file index screen. May be displayed. Alternatively, the flag information index screen displays a representative image related to all flag information added to the selected moving image file, and displays a flag information in which recorded information of still image data is not recorded. You may do.

  After the still image data corresponding to the flag information is recorded on the recording medium 108, the control unit 105 may delete the flag information from the moving image file. In this case, on the video file index screen, representative images of all video files to which flag information is added are displayed, and on the flag information index screen, all flag information added to the selected video file. A representative image is displayed.

  In the configuration described above, in order to determine flag information for recording still image data, an index screen for flag information added to the selected video file is displayed after displaying a video file index screen. Not limited to. For example, a flag for displaying the representative image regarding all flag information added to the moving image file recorded on the recording medium 108 as an index screen without displaying the above-described moving image file index screen, and recording still image data to the user Information may be determined. At this time, the control unit 105 may control to generate and display a representative image that can identify flag information in which recorded information of still image data is not recorded. Further, the representative image of flag information displayed on the index screen may be only the representative image of flag information in which recorded information of still image data is not recorded.

  In addition, the control unit 105 causes the signal processing unit 103 to generate still image data corresponding to the flag information selected by the user from the above-described moving image file index screen or flag information index screen, and causes the display unit 109 to display the still image data. Also good. Then, when still image data corresponding to flag information is displayed on the display unit 109, still image data corresponding to flag information may be recorded by a recording instruction for the still image data being displayed.

(Processing for still image data corresponding to flag information)
FIG. 5 is a flowchart showing processing when a predetermined processing is instructed for still image data corresponding to flag information. The flowchart of FIG. 5 is started based on the program stored in the memory 102 when the digital camera 100 is set to the reproduction mode or the editing mode.

  In step S501, the control unit 105 displays an index screen related to still image data. Here, the index screen related to still image data includes, for example, a representative image of a still image file recorded on the recording medium 108 and a representative image related to flag information added to a moving image file recorded on the recording medium 108. It is an index screen including. The representative image related to the flag information is generated and displayed as described above. A representative image is selected in accordance with a user instruction input from the operation unit 106 on the index screen related to still image data (step S502).

  The control unit 105 performs a process of displaying still image data of the selected representative image on the display unit 109 instead of the index screen related to the still image data (step S503). When the representative image of the still image file recorded on the recording medium 108 is selected, the control unit 105 performs control so that still image data included in the still image file is displayed on the display unit 109. When a representative image related to flag information added to the moving image file recorded on the recording medium 108 is selected, still image data corresponding to the flag information is generated from the moving image file and displayed as described above. The control unit 105 performs control so as to display on the unit 109.

  In step S <b> 504, the control unit 105 determines whether an instruction to perform some processing is input via the operation unit 106. If no instruction to perform processing is input, the display of still image data of the representative image selected in step S502 is continued. When an instruction to perform processing is input (Yes in step S504), in step S505, the control unit 105 processes the still image data to be processed in which the input instruction is a representative image selected in step S502. Judge whether or not the instruction. Here, the processing for processing still image data includes processing for enlarging and reducing the display of still image data, processing for protecting still image data, processing for rotating the display direction of still image data, processing for trimming, and the like. It is processing. In the present embodiment, the processing of still image data does not include processing for deleting still image data and processing for ending display of still image data.

Specifically, the control unit 105 controls the signal processing unit 103 to generate the still image data of the representative image selected in step S502 based on the flag information, and records the generated still image data as a still image file. The recording / reproducing unit 107 is controlled to record on the medium 108. In step S508, in response to the recording of the still image file on the recording medium 108, the control unit 105 adds the recorded information of the still image data to the flag information corresponding to the still image data and records the flag information. Update information.

  In step S509, the control unit 105 performs control so that the processing instruction input in step S504 is executed on the still image data to be processed.

  The control unit 105 determines whether or not to end the process in step S510, and when other processes are to be continued (No in step S510), executes the process input in step S514 in step S509. When an instruction to end the process for the still image data to be processed selected in step S502 is input, or when an instruction to change the mode or an instruction to turn off the digital camera 100 is given, the control unit 105 In step S510, “Yes” is determined. In step S511, the control unit 105 determines whether to record the still image data processed in step S509 on the recording medium 108 based on an instruction input by the user via the operation unit 106. When recording the processed still image data on the recording medium 108 (Yes in step S511), in step S512, the control unit 105 records the still image data processed in step S509 as a processed still image file as the recording medium 108. To record.

  At this time, in this embodiment, the still image data processed in step S509 is replaced with the still image file recorded in step S507 or a still image file different from the still image file recorded before the current processing. To the recording medium 108. However, the present invention is not limited thereto, and the still image data processed in step S509 is recorded in the form of overwriting the still image file recorded in the recording medium 108, such as the still image file of the representative image selected in step S502. Also good.

  The index screen displayed in step S501 is not limited to the index screen related to still image data, and the index screen may include a representative image of a moving image file recorded on the recording medium 108. However, the processing from step S506 to step S508 is performed only when a representative image related to still image data is selected. When the representative image of the moving image file is selected in step S502, and the control unit 105 determines Yes in step S505, the process proceeds to step S509.

  Further, a case has been described in which, when still image data corresponding to flag information is recorded on the recording medium 108, recorded information indicating that still image data has been recorded is recorded in the flag information. However, it is not limited to this. In the configuration in which the flag information is deleted when the still image data corresponding to the flag information is recorded on the recording medium 108, in step S506, the control unit 105 determines that the representative image selected in step S502 is the still image data corresponding to the flag information. It is determined whether it is a representative image. If the representative image selected in step S502 is a representative image of still image data corresponding to the flag information, the control unit 105 determines No in step S506 and advances the process to step S507. When the representative image selected in step S502 is not the representative image of the still image data corresponding to the flag information but the representative image of the still image file recorded on the recording medium 108, the control unit 105 determines Yes in step S506. And the process proceeds to step S509.

  In the process of step S507, the control unit 105 notifies the user that the processing target still image data is not recorded on the recording medium 108, and whether or not the user records the processing target still image data on the recording medium 108. May be configured to be selectable. When the user selects not to record the still image data to be processed in the recording medium 108, the control unit 105 does not perform the processes in steps S507 and S508, and advances the process to step S509. In step S509, the control unit 105 generates the still image data to be processed from the video file based on the flag information by the signal processing unit 103, and performs the processing in step S506 in a state where the still image data is stored in a buffer (not shown). Do.

  In step S507, the control unit 105 does not record the corresponding still image data in the recording medium 108 among the other flag information added to the moving image file to which the flag information of the still image data to be processed is added. Still image data corresponding to the flag information may be recorded. Further, the determination in step S506 and the process of recording the still image file in step S507 are performed when the processing of the still image data to be processed is instructed in step S505, but is not limited thereto. For example, the determination in step S506 and the processing for recording the still image file in step S507 may be performed after the display processing of the still image data in step S503, or after the processing is determined to be terminated in step S510. Also good.

  As described above, when flag information based on an instruction to acquire a part of moving image data as still image data is added to the moving image file, the still image data corresponding to the flag information can be easily recorded as a still image file. Can be recorded. Still image data corresponding to the flag information when the still image data corresponding to the flag information is not recorded as a still image file on the recording medium and a predetermined process such as a processing process is instructed on the still image data. Can be recorded on a recording medium. In this embodiment, even if the user does not give an instruction to record still image data corresponding to the flag information on the recording medium, the still image data corresponding to the flag information is changed according to an instruction of a predetermined process such as a processing process. It can be recorded on a recording medium.
