Embodiments according to the present invention will be described below with reference to the accompanying drawings.
(First embodiment)
FIG. 1 is a block diagram of an imaging recording / reproducing apparatus according to the present embodiment. The imaging recording / reproducing apparatus 1 is, for example, a video camera that can record a moving image or reproduce a recorded moving image.

The imaging recording / reproducing apparatus 1 can set a recording mode and a reproduction mode as operation modes. The recording mode is a mode for photographing a subject video and recording a captured moving image on a recording medium by a predetermined designation operation by a user. The playback mode is a mode for playing back a recorded moving image.
Furthermore, the imaging recording / reproducing apparatus 1 can set a normal recording mode and a pre-recording mode as recording modes. The normal recording mode is a mode in which a moving image captured based on a predetermined designation operation by the user is recorded after the designation operation. Here, recording of a moving image after the designation operation is referred to as trigger recording. On the other hand, the pre-recording mode is a mode for recording a moving image from a predetermined time before a specified operation before a specified operation by the user in addition to the normal recording mode. Here, recording of a moving image from a predetermined time before the designated operation to the designated operation is referred to as pre-recording. The normal recording mode and the pre-recording mode are set by a specific setting operation by the user.

  As shown in FIG. 1, the imaging recording / reproducing apparatus 1 includes a microprocessor 10, a program memory 11, and an image storage memory 12. The microprocessor 10 controls the operation of the entire imaging recording / reproducing apparatus 1. The program memory 11 is connected to the microprocessor 10 and stores a program for executing a flowchart to be described later, a program for executing a photographing recording / reproducing operation, and the like. The image storage memory 12 is connected to the microprocessor 10 and stores a moving image captured from a predetermined time before a predetermined designation operation by the user when the above-described pre-recording mode is set. Is possible.

The imaging recording / reproducing apparatus 1 includes an imaging lens 20, a video sensor 30, an image processing / control circuit 40, a data compression / decompression circuit 50, a recording medium 61, and a display device 80.
The video sensor 30 converts the optical image from the imaging lens 20 into an electrical signal. The image processing / control circuit 40 converts the electrical signal output from the video sensor 30 into image data and controls the image data. The data compression / decompression circuit 50 sequentially compresses or decompresses the image data processed by the image processing / control circuit 40. The recording medium 61 is a recording medium for recording the image data processed by the data compression / decompression circuit 50 via the microprocessor 10. The display device 80 is a display for displaying an image captured by the imaging lens 20, an operation state according to a state in which the microprocessor 10 executes a program, a message, and the like using characters and images. The display device 80 is not limited to being provided in the imaging recording / reproducing device 1, and may be an external display device connected via an external output terminal (not shown) provided in the imaging recording / reproducing device 1. .

  The imaging recording / reproducing apparatus 1 includes a recording medium control unit 60, a thumbnail image generation unit 70, a thumbnail image display processing unit 71, and a KEY processing unit 94. The recording medium control unit 60 performs control for recording or reproducing image data on the recording medium 61. The thumbnail image generation unit 70 generates thumbnail data of thumbnail images from the image data processed by the data compression / decompression circuit 50. The thumbnail data generated by the thumbnail image generation unit 70 is stored in the image storage memory 12 via the microprocessor 10. The thumbnail image display processing unit 71 creates data for displaying a list of thumbnail images on the display device 80 from the thumbnail data stored in the image storage memory 12. The KEY processing unit 94 determines and processes setting by an operation mode changeover switch 90, a trigger switch 91, and a pre-record setting switch 92, which will be described later, and input by the up / down / left / right direction instruction unit 93.

The imaging recording / reproducing apparatus 1 includes an operation mode changeover switch 90, a trigger switch 91, a pre-record setting switch 92, and an up / down / left / right direction instruction unit 93. The operation mode changeover switch 90 is a switch for the user to select an operation mode of the imaging recording / reproducing apparatus 1 as a recording mode or a reproduction mode.
The trigger switch 91 is a switch for the user to start trigger recording. When the user presses the trigger switch 91, the imaging recording / reproducing apparatus 1 starts a process of recording the captured moving image on the recording medium 61. Here, the act of the user pressing the trigger switch 91 corresponds to an example of a predetermined designation operation by the user.
The trigger switch 91 is a switch for the user to stop recording. Accordingly, when the user presses the trigger switch 91 while the moving image is being recorded, the imaging recording / reproducing apparatus 1 stops the process of recording the captured moving image on the recording medium 61.

  The pre-recording setting switch 92 is a switch for the user to select the recording mode of the imaging recording / reproducing apparatus 1 as the normal recording mode or the pre-recording mode. For example, the user selects the pre-recording mode. In this case, the image-recording / reproducing apparatus 1 includes one of a moving image captured a predetermined time before the user presses the trigger switch 91 and a moving image captured after the trigger switch 91 is pressed. One moving image file is recorded on the recording medium 61. Note that the operation mode changeover switch 90, the trigger switch 91, and the pre-record setting switch 92 may be configured not to be switches but to be selected by an operation by key input by the user.

  The up / down / left / right direction instructing unit 93 inputs an instruction for the user to select or determine the thumbnail images listed on the display device 80 when the imaging recording / reproducing apparatus 1 is set to the reproduction mode. It is an operation key for

Next, an operation process when the normal recording mode is set as the recording mode of the imaging recording / reproducing apparatus 1 will be described. The range of the period during which the imaging / recording / reproducing apparatus 1 records a moving image and the position where a still image is extracted as a thumbnail image from the captured moving image will be described with reference to FIG.
First, the user uses the operation mode changeover switch 90 to select the operation mode as the recording mode, and uses the pre-record setting switch 92 to select the recording mode as the normal recording mode. The KEY processing unit 94 detects these selections and sets the recording mode to the normal recording mode.

When the user depresses the trigger switch 91 in the normal recording mode, the recording medium control unit 60 records the moving image data processed by the data compression / decompression circuit 50 on the recording medium 61. That is, when the KEY processing unit 94 detects that the trigger switch 91 is pressed, the recording medium control unit 60 starts trigger recording.
When the user presses the trigger switch 91 again, the recording medium control unit 60 stops trigger recording.
That is, when the normal recording mode is set, as shown in FIG. 2, the range T1 from when the trigger switch is pressed until the trigger switch is pressed again is the range of the trigger recording period.

Subsequently, the recording medium control unit 60 and the microprocessor 10 create file management data in the program memory 11 so that the moving image recorded by the trigger is recognized as one moving image file.
Further, the thumbnail image generation unit 70 extracts a predetermined frame of the moving image trigger-recorded on the recording medium 61 as a still image, generates a thumbnail image, and stores the thumbnail image in the image storage memory 12 as a thumbnail image for trigger recording. . Here, as shown in FIG. 2, the frame extracted by the thumbnail image generation unit 70 as the still image is the first frame A of the moving image that has been trigger-recorded. At this time, the microprocessor 10 stores the file management data in the program memory 11 so that the thumbnail image is recognized as a thumbnail image of a moving image recorded as one trigger.

Next, an operation process when the reproduction mode is set as the operation mode of the imaging recording / reproducing apparatus 1 will be described.
First, the user uses the operation mode changeover switch 90 to select the operation mode as the reproduction mode. The KEY processing unit 94 detects this selection and sets the reproduction mode. When the playback mode is set, the thumbnail image display processing unit 71 displays the trigger recording thumbnail image stored in the image storage memory 12 on the display device 80. Here, FIG. 3 shows a list of thumbnail images displayed on the display device 80. FIG. 3 shows a list of thumbnail images 31 of the first frame A of the moving images recorded in the trigger and thumbnail images stored in the image storage memory 12 in a list.

Next, operation processing when the pre-recording mode is set as the recording mode of the imaging recording / reproducing apparatus 1 will be described with reference to the flowchart shown in FIG. The flowchart shown in FIG. 4 is realized by the microprocessor 10 executing a program stored in the program memory 11. The range of the period during which the imaging / recording / reproducing apparatus 1 records a moving image and the position where a still image is extracted as a thumbnail image from the captured moving image will be described with reference to FIG.
First, in step S10, the user uses the operation mode changeover switch 90 to select the operation mode as the recording mode, and uses the prerecording setting switch 92 to select the recording mode as the prerecording mode. The KEY processing unit 94 detects these selections and sets the recording mode to the pre-recording mode.

In step S11, when the pre-recording mode is set, the microprocessor 10 starts storing the moving image (moving image data) processed by the data compression / decompression circuit 50 in the image storage memory 12. This process corresponds to an example of a second recording processing unit. Here, the microprocessor 10 stores the moving image in the image storage memory 12 for a predetermined time before trigger recording is started when the trigger switch 91 is pressed. Here, the predetermined time is, for example, 10 seconds.
That is, when the pre-recording mode is set, as shown in FIG. 2, the range T2 from when the trigger switch is pressed until the trigger switch is pressed is the range of the period during which the image storage memory 12 is recorded. It is. In addition, you may comprise so that a user can set arbitrarily this time.

In step S12, the KEY processing unit 94 detects whether or not the trigger switch 91 is pressed by the user. If it is detected that the trigger switch 91 has been pressed, the process proceeds to step S13. Note that if the depression of the trigger switch 91 is not detected, the KEY processing unit 94 waits until the trigger switch 91 is depressed by the user.
Here, if the time from when the pre-recording mode is set to when the trigger switch 91 is pressed is long, the predetermined time for storing the moving image data is exceeded. In this case, the microprocessor 10 controls to discard the moving image data stored in the image storage memory 12 from time-old data at any time, and updates the time management data. Note that the microprocessor 10 is not limited to discarding the moving image data stored in the image storage memory 12 from the time-old data at any time. For example, the microprocessor 10 may control to overwrite the portion where the moving image data is stored, and update the time management data.

In step S <b> 13, the recording medium control unit 60 records the moving image processed by the data compression / decompression circuit 50 on the recording medium 61. That is, when the KEY processing unit 94 detects that the trigger switch 91 is pressed, the recording medium control unit 60 starts trigger recording. This process corresponds to an example of a first recording processing unit.
That is, as shown in FIG. 2, trigger recording for recording a moving image on the recording medium 61 is started after the trigger switch is pressed.

At the same time, in step S14, the thumbnail image generation unit 70 extracts the image of the frame B shown in FIG. 2, which is the first frame of the moving image stored in the image storage memory 12, as a still image, and pre-records the thumbnail. Generate an image. The process corresponds to an example of a second image generation unit. The prerecorded thumbnail image corresponds to the second thumbnail image. The thumbnail image generation unit 70 stores the generated pre-recorded thumbnail image in the image storage memory 12.
Subsequently, the microprocessor 10 moves the moving image stored in the image storage memory 12 to the recording medium 61. The movement control by the microprocessor 10 ends when all moving images stored in the image storage memory 12 move to the recording medium 61.

In step S15, the KEY processing unit 94 detects whether or not the trigger switch 91 is pressed again by the user. If it is detected that the trigger switch 91 has been pressed, the process proceeds to step S16. Note that if the depression of the trigger switch 91 is not detected, the KEY processing unit 94 waits until the trigger switch 91 is depressed by the user.
In step S16, the recording medium control unit 60 stops trigger recording.

In step S <b> 17, the recording medium control unit 60 and the microprocessor 10 store the file in the program memory 11 so that the trigger-recorded moving image and the pre-recorded moving image are recognized as one continuously recorded moving image file. Create management data. This process corresponds to an example of a file creation unit.
In step S18, the thumbnail image generation unit 70 extracts the image of frame A shown in FIG. 2, which is the first frame of the moving image trigger-recorded on the recording medium 61, as a still image, and generates a thumbnail image for trigger recording. . This process corresponds to an example of a first image generation unit. The thumbnail image for trigger recording corresponds to the first thumbnail image. The thumbnail image generation unit 70 stores the generated trigger recording thumbnail image in the image storage memory 12. At this time, the recording medium control unit 60 and the microprocessor 10 perform processing so as to be recognized as a thumbnail image extracted from one moving image file in which a thumbnail image for trigger recording and a thumbnail image for pre-recording are continuously recorded. Do. Specifically, the recording medium control unit 60 and the microprocessor 10 update the file management data in the program memory 11.

Next, an operation process when the reproduction mode is set as the operation mode of the imaging recording / reproducing apparatus 1 will be described with reference to a flowchart shown in FIG. The flowchart shown in FIG. 5 is realized by the microprocessor 10 executing a program stored in the program memory 11.
First, in step S20, the user uses the operation mode changeover switch 90 to select the operation mode as the reproduction mode. The KEY processing unit 94 detects this selection and sets the reproduction mode.
In step S21, when the playback mode is set, the thumbnail image display processing unit 71 superimposes the pre-recording thumbnail image and the trigger recording thumbnail image stored in the image storage memory 12 with a slight shift and overlaps them. To display. This process corresponds to an example of display control means.

Here, FIG. 6 shows a list of thumbnail images displayed on the display device 80. In FIG. 6, a thumbnail image 41 of the first frame A of the moving image that has been trigger-recorded and a thumbnail image 42 of the first frame B of the pre-recorded moving image are displayed. In FIG. 6, thumbnail images stored in the image storage memory 12 are displayed in a list.
Here, the thumbnail image display processing unit 71 displays the thumbnail image 42 on the front and the thumbnail image 41 on the back. Also, the thumbnail image display processing unit 71 displays the thumbnail image 41 and the thumbnail image 42 so as to overlap each other while being shifted vertically and horizontally. Note that the thumbnail image 41 and the thumbnail image 42 may be displayed so as to overlap each other at least in the vertical and horizontal directions. Here, a thumbnail image that is not displayed in a superimposed manner is a moving image file that includes only a trigger recorded moving image. Therefore, by displaying in this way, the user can immediately determine whether or not the displayed moving image file includes a pre-recorded moving image.

  Returning to the flowchart shown in FIG. 5, in step S22, the KEY processing unit 94 determines whether or not the user has detected selection of a thumbnail image. The process corresponds to an example of a selection detection unit. If the KEY processing unit 94 detects selection of a thumbnail image by the user, the process proceeds to step S23. If no selection is detected, the process proceeds to step S24.

  In step S23, the thumbnail image display processing unit 71 displays the selected thumbnail image in front of the unselected thumbnail image. Here, a display transition example of the display device 80 by selecting a thumbnail image will be specifically described with reference to FIG. First, as shown in FIG. 7A, first, it is assumed that the selection frame 100 surrounds and displays the pre-recorded thumbnail image 42. The KEY processing unit 94 detects the selection of the thumbnail image 41 for trigger recording by, for example, an operation of pressing the up / down / left / right direction indicating unit 93 in the left / right direction among the up / down / left / right direction indicating units 93 by the user. Then, the thumbnail image display processing unit 71 moves the selection frame 100 to the thumbnail image 41 for trigger recording as shown in FIG. Further, the thumbnail image display processing unit 71 displays the selected trigger recording thumbnail image 41 in a slightly shifted manner in front of the pre-recording thumbnail image 42.

  Conversely, as shown in FIG. 7B, from the state in which the selection frame 100 surrounds and displays the trigger recording thumbnail image 41, the KEY processing unit 94 causes the user to perform a prerecording thumbnail. Assume that selection of the image 42 is detected. In this case, as shown in FIG. 7A, the thumbnail image display processing unit 71 moves the selection frame 100 to the thumbnail image 42 for pre-recording, and the thumbnail image 42 for pre-recording is used as the thumbnail image for trigger recording. 41 is displayed with a slight shift on the front of 41. This switching display for exchanging the thumbnail images forward and backward is repeated until a selection decision is detected in the next step S24.

  In step S <b> 24, the KEY processing unit 94 determines whether or not the user has determined to select a thumbnail image. When the KEY processing unit 94 detects the selection decision by the operation of the up / down / left / right direction instruction unit 93 by the user, the process proceeds to step S25. On the other hand, if the selection decision is not detected, the process returns to step S22.

In step S25, the microprocessor 10 starts reproduction from the selected thumbnail image. Here, specifically, with reference to FIG. 8 and FIG. 9, a moving image that is reproduced by determining the selection of thumbnail images will be described.
First, as shown in FIG. 8A, when the determination is detected in a state where the pre-recording thumbnail image 42 is selected, the microprocessor 10 reproduces from the pre-recorded moving image. That is, as shown in FIG. 8 (b), playback is performed from the first frame B of the pre-recorded moving image, and the continuously recorded moving image is played back.
On the other hand, as shown in FIG. 9A, when the determination is detected in a state where the thumbnail image 41 for trigger recording is selected, the microprocessor 10 performs playback from the moving image recorded in the trigger. That is, as shown in FIG. 9B, playback is performed from the first frame A of the moving image recorded by trigger recording, and the pre-recorded moving image is not played back.

As described above, according to the present embodiment, the user can check whether there is a prerecorded thumbnail image displayed on the display device, so that the prerecorded moving image is included in the moving image file. It can be easily determined whether or not.
In addition, when the time from when the pre-recording mode is set to when trigger recording is started is equal to or shorter than a predetermined time (for example, 2 seconds), only the thumbnail image for trigger recording is displayed on the display device 80. It may be.

(Second Embodiment)
Next, a display method for displaying a pre-recording thumbnail image and a trigger recording thumbnail image according to the second embodiment will be described with reference to FIG. The configuration of the imaging recording / reproducing apparatus 1, the recording mode operation process, and the reproduction mode operation process are substantially the same as those in the first embodiment, and a description thereof will be omitted.

  When the reproduction mode is set in the imaging recording / reproducing apparatus 1, the thumbnail image display processing unit 71 displays a list of thumbnail images for each image file, as shown in FIG. Here, for the moving image file 101 including the pre-recorded moving image in the thumbnail image list, the thumbnail image display processing unit 71 slightly adds the pre-recorded thumbnail image 42 and the trigger recording thumbnail image 41. They are displayed in a superimposed manner.

In the present embodiment, the thumbnail image display processing unit 71 performs a pre-recording thumbnail image 42 and a trigger recording thumbnail image 41 every predetermined time (for example, every 3 seconds) as shown in FIG. Display before and after. That is, the thumbnail image display processing unit 71 repeats and displays the display of FIG. 10A and FIG. 10B every predetermined time.
As described above, according to the present embodiment, it is possible to alternately check trigger-recorded thumbnail images and pre-recorded thumbnail images without the user selecting a thumbnail image.

(Third embodiment)
Next, a display method for displaying a pre-recording thumbnail image and a trigger recording thumbnail image according to the third embodiment will be described with reference to FIG. The configuration of the imaging recording / reproducing apparatus 1, the recording mode operation process, and the reproduction mode operation process are substantially the same as those in the first embodiment, and a description thereof will be omitted.

  When the reproduction mode is set in the imaging / recording / reproducing apparatus 1, the thumbnail image display processing unit 71 displays a list of thumbnail images for each image file. Here, only one moving image file 111 will be described. As shown in FIG. 11A, the thumbnail image display processing unit 71 displays the pre-recording thumbnail image 42 and the trigger recording thumbnail image 41 so as to be slightly shifted and overlapped as shown in FIG. . In FIG. 11A, the thumbnail image display processing unit 71 displays a selection frame 100 so as to surround the pre-recorded thumbnail image.

In the present embodiment, the thumbnail image display processing unit 71 displays the selected pre-recording thumbnail image 42 as usual, as shown in FIG. Moreover, the thumbnail images 41 for trigger recording that are not selected are not displayed every predetermined time (for example, every 3 seconds) as shown in FIG. 11B. That is, the thumbnail image display processing unit 71 displays a thumbnail image that has not been selected by blinking at a predetermined time interval. When the selection of the thumbnail image is changed by the user, the newly selected thumbnail image is displayed as usual, and the unselected thumbnail image is displayed blinking.
As described above, according to the present embodiment, the user confirms whether or not there is a blinking thumbnail image on the display device, thereby determining whether or not the pre-recorded moving image is included in the moving image file. Can be easily determined.

(Fourth embodiment)
Next, a display method for displaying a pre-recording thumbnail image and a trigger recording thumbnail image according to the fourth embodiment will be described with reference to FIG. The configuration of the imaging recording / reproducing apparatus 1, the recording mode operation process, and the reproduction mode operation process are substantially the same as those in the first embodiment, and a description thereof will be omitted.

  When the reproduction mode is set in the imaging / recording / reproducing apparatus 1, the thumbnail image display processing unit 71 displays a list of thumbnail images for each image file. Here, only one moving image file 121 will be described. As shown in FIG. 12, the thumbnail image display processing unit 71 displays a thumbnail image 42 for pre-recording and a thumbnail image 41 for trigger recording in a slightly shifted manner and superimposed on each other as shown in FIG. In FIG. 12, the thumbnail image display processing unit 71 displays a selection frame 100 so as to surround the pre-recorded thumbnail image.

In the present embodiment, the thumbnail image display processing unit 71 displays the image frame of the pre-recorded thumbnail image 42 as a square as usual, as shown in FIG. Further, the image frame of the trigger recording thumbnail image 41 which is not selected is different from the shape of the image frame of the pre-recording thumbnail image 42, for example, as shown in FIG. It is displayed in an elliptical shape. That is, the thumbnail image display processing unit 71 displays the shape of the image frame of the selected thumbnail image and the shape of the image frame of the unselected thumbnail image in different shapes. When the selection of the thumbnail image by the user is changed, the image frame of the newly selected thumbnail image is displayed as a square as usual, and the image frame of the unselected thumbnail image is displayed in a different shape. .
Thus, according to the present embodiment, the user can check whether there is a thumbnail image of an image frame having a different shape on the display device, so that the moving image pre-recorded in the moving image file is included. It can be easily determined whether or not there is.

  Note that the present invention is not limited to the first to fourth embodiments described above. For example, the thumbnail image display processing unit 71 differs between a pre-recorded thumbnail image and a trigger-recorded thumbnail image that are displayed in a shifted manner and a thumbnail image that is not selected and a thumbnail image that is not selected. It may be displayed after image processing. Here, as the image processing, for example, an unselected thumbnail image is displayed in black and white or displayed at a low resolution.

In the first to fourth embodiments described above, the case where the first frame of each moving image is extracted as the thumbnail image for trigger recording and the thumbnail image for pre-recording has been described. However, the present invention is not limited to this case. . For example, a thumbnail image may be generated by extracting a still image from an arbitrary frame (for example, the 10th frame).
In the first to fourth embodiments described above, only the case of displaying the trigger recording thumbnail image and the pre-recording thumbnail image on the display device 80 has been described. However, the present invention is not limited to this case. For example, an image related to trigger recording and an image related to pre-recording may be used. That is, for example, several frames may be extracted and the extracted frames may be displayed continuously.
