  The recording / reproducing apparatus 100 can record the input video data and audio data on the recording medium 110, and can reproduce the video / audio data recorded on the recording medium 110. In addition, when recording video data and audio data, recording is performed according to a predetermined standard.

  The video data input unit 101 receives, for example, a digital signal of a video signal input from an imaging unit of a camera, and the audio data input unit 103, for example, audio of a digital signal obtained by AD-converting an audio signal input from a microphone Data is entered. Data input to the video data input unit 101 and the audio data input unit 103 may be other than the camera. For example, there are video data and audio data demodulated by a TV tuner. The video compression / decompression unit 102 compresses the video data input from the video data input unit 101 and decompresses the compressed video data input from the demultiplexing unit 105. The audio compression / decompression unit 104 compresses the audio data input from the audio data input unit 103, or expands the compressed audio data input from the demultiplexing unit 105. The demultiplexing unit 105 synchronizes the video data compressed by the video compression / decompression unit 102 and the audio data compressed by the audio compression / decompression unit 104 along the time axis, and generates stream data synthesized as one data To do. Further, the stream data obtained from the recording medium 110 is separated into video data and audio data. The stream data refers to moving image data or still image data, and refers to data recorded in the recording medium 110. The recording medium control unit 106 controls the amount of data for storing the stream data in the recording medium 110 and the storage timing. The recording medium 110 stores a file in which stream data is stored. In addition, the recording medium 110 stores a database. In this embodiment, the recording medium 110 is detachable from the recording apparatus 100, but may be incorporated in the recording apparatus. In the present embodiment, a memory card using a flash memory is assumed as a recording medium. However, the present invention can be applied to storage other than the memory card. For example, an optical disc such as a Blu-ray Disc or a DVD, an HDD, or an SSD can be mentioned. One or more of these storages can be connected to the recording apparatus 100. The recognizing unit 107 extracts a certain feature (: a predetermined feature determined in advance) from the video data and audio data, and “recognizes” when the condition is met. The recognition in the recognition unit 107 is image analysis for video data, and frequency analysis for audio data. For example, the input video data is subjected to image analysis to recognize a human face. The memory 109 holds data for the recognition unit 109 to analyze video data and audio data. The recognition control unit 108 activates, stops, or controls the function of the recognition unit 107. The database management unit 111 manages the database by storing the recognition data obtained by the recognition unit 107 in a database constructed on the recording medium 110 as a data set, or by taking out the data on the contrary.

  Here, the video compression / decompression unit 102, the audio compression / decompression unit 104, the demultiplexing unit 105, the recording medium control unit 106, the recognition unit 107, and the recognition control unit 108 are configured to execute operations as hardware as circuits. Alternatively, the program may be stored in a memory as a program and executed in software.

  FIG. 2 is a diagram illustrating an example of a software configuration of the recording / reproducing apparatus. Solid arrows show the direction of data and control.

  In FIG. 2, reference numeral 200 denotes recording / reproducing software of the recording / reproducing apparatus 100. The recording / playback software 200 mainly comprises a system task 201, a scene management task 202, a database management task 203, a recognition task 204, a recording / playback task 205, a video / audio compression / decompression task 206, and a recording medium driver 207.

  The system task 201 controls the operation of each task. For example, when recording video data, the video compression / decompression task is instructed to compress the video data, and the recording / playback task is instructed to record the video compression data as a stream file on the recording medium 110. Conversely, when playing back video data, the recording / playback task is instructed to read the video data file recorded on the recording medium 110, and the video compression / decompression task is to decompress the read video data. Instruct. The scene management task 202 creates scene information each time recording is executed. Further, in the present invention, the scene management task is linked to the recognition task, and when the recognition task recognizes during recording of the video data, a notification is received. Do. It is the database management task that controls the database. Therefore, the scene management task instructs the database management task to edit data. The recognition task 204 extracts image features by analyzing the image data obtained by the image compression / decompression task. If the target image can be recognized, the scene management task is notified. The recording / playback task 205 controls recording and playback of video data. At that time, control according to standards such as MPEG and AVCHD is performed. The recording medium driver 207 controls writing and reading of data to and from the recording medium 110. The recording / playback task and the database management task do not directly write or read data on the recording medium 110 but access data via the recording medium driver. The recording medium 110 holds video data 209 and a database 210.

  FIG. 3 is a diagram showing a processing flow for registering recognition information in a database when a target image is recognized during recording.

  The recognition task first checks whether the recognition function is turned on (S301). If the recognition function is off (S301: NO), the process ends. If the recognition function is on (S301: YES), the next process (S302) is executed. The recognition control unit 108 switches the recognition function on and off. The video data input from the video data input unit 101 is subjected to image analysis (S302). If the recognition unit 107 recognizes the target image as a result of the analysis (S303: YES), the scene management task is notified of the recognition. (S303), the next process (S304) is executed. If not recognized, the next process (S304) is executed. It is confirmed whether the recording / reproducing apparatus 100 has stopped recording (S304). If the recording is not stopped (S304: NO), the process returns to S302 again to continue the process. If the recording is stopped (S304: YES), the process is terminated.

  On the other hand, the scene management task waits for a recognition notification notified from the recognition task (S310). When notification is received, the next processing (S311) is executed. It is checked whether the conditions registered in the database are met (S311). If the condition is met (S311: YES), information is registered in the database (S312), and the next process (S313) is executed. If the condition is not met (S311: NO), the next process (S313) is executed. If the recording is not stopped (S313: NO), the process returns to S310 again, and the process is continued. If the recording is stopped (S313: YES), the process is terminated.

(2) Database FIG. 4 shows data items 410 to be registered in the database 210 when recognized by the recognition unit 107. Reference numeral 411 indicates the meaning of the item 410, and 412 indicates the data size of the item 410. The item 410 of the database registration item 400 includes a file identification number 401, a recording date 402, a recognition time 403, a recognition position (x coordinate) 404, a recognition position (y coordinate) 405, a recognition size (x coordinate) 406, and a recognition size (y Coordinate) 407, recognition accuracy 408, and thumbnail 409.

  The file identification number 401 is a number for identifying the stream file being recorded when it is recognized. The recording date and time 402 is the date and time of recognition, and the recognition time 403 is the time of continuous recognition. The recognition position (x coordinate) 404 is the x coordinate position of the image data when recognized, and the recognition position (y coordinate) is the y coordinate position at that time. The recognition size (x coordinate) 406 is the size of the image data recognized from the recognition position (x coordinate) 404 in the x coordinate direction. Similarly, the recognition size (y coordinate) 407 is the size of the image data recognized from the recognition position (y coordinate) 405 in the y coordinate direction. The recognition accuracy 408 is a value representing an index indicating the probability of recognition. The thumbnail 409 is image data obtained by reducing the image data at the time of recognition. In FIG. 4, the image data size is 10 Kbytes as an example. If the image data of the thumbnail 409 is not generated, there is no data.

FIG. 5 is a diagram illustrating an example of data to be registered in the database.
In the database 500, each data item 410 shown in FIG. 4 has a value. Each time the recognition unit 107 recognizes the target image and satisfies the condition for registering the recognition information in the database 500, it is recorded in the database 500 held by the recording medium 110 via the database management unit 111 and the recording medium control unit 106. The

(3) Database Registration Timing FIG. 6 is a diagram showing database registration timing when the recognition of the target image is repeated within a short time.

  A scene 600 is a single piece of video / audio data recorded by the recording / reproducing apparatus 100, and indicates a range from the recording start position 601 to the recording stop position 602 of the video data input to the recording / reproducing apparatus 100. The recording start position 601 is determined by, for example, pressing a recording button by operating the recording / reproducing apparatus 100, and the recording stop position 602 is determined by operating the recording / reproducing apparatus 100, for example, by pressing the recording button again during recording. The unrecognized video 610 is a video at a moment when the recognition unit 107 cannot recognize the target image in the scene being recorded. On the other hand, the recognized video 611 is a video at the moment when the recognition unit 107 recognizes the target image in the scene being recorded. The database registration position 603 indicates a timing position at which the database management unit 111 registers recognition information in the database 210 when the recognition unit 107 recognizes a target image. The scene image at this time is a recognized image 611.

  While video data input to the recording / reproducing apparatus 100 is being recorded, even if the recognition unit 107 recognizes the target image, it may be immediately deviated from the recognition. In this case, since there is a possibility of erroneous recognition, the recognition information at that time is not registered in the database in the case where the recognition is immediately deviated. However, there are cases where recognition and derecognition are repeated, such as recognizing again even if recognition is lost immediately after recognition. This is considered to be in such a situation because the target image is an image in the middle of recognizable and impossible. When recognition and derecognition are repeated in this way, if the number of repetitions reaches a predetermined number of times, it is regarded as being recognized, and the recognition information is registered in the database. In the example of FIG. 6, it is registered in the database by the third recognition. This number can be freely set by software.

  FIG. 7 is a diagram showing the database registration timing when the recognition is performed for a certain time or more.

  A scene 700 is a single piece of video / audio data recorded by the recording / reproducing apparatus 100, and indicates a range from the recording start position 701 to the recording stop position 702 of the video data input to the recording / reproducing apparatus 100. The recording start position 701 is determined by, for example, pressing a recording button by operating the recording / reproducing apparatus 100, and the recording stop position 702 is determined by operating the recording / reproducing apparatus 100, for example, by pressing the recording button again during recording. The unrecognized video 610 is a video at a moment when the recognition unit 107 cannot recognize the target image in the scene being recorded. On the other hand, the recognized video 611 is a video at the moment when the recognition unit 107 recognizes the target image in the scene being recorded. A database registration position 703 indicates a timing position at which the database management unit 111 registers recognition information in the database 210 when the recognition unit 107 recognizes a target image. The image of the scene at this time is a recognized image 711.

  When the recognizing unit 107 analyzes the video data input to the recording / reproducing apparatus 100 and recognizes the target image, the recognition information is not registered in the database immediately, but is registered after a certain period of time. This is to prevent erroneous recognition described in FIG. 6 and to limit database registration. The reason for restricting database registration is that when displaying a list of recognized target images in a recorded scene after stopping recording as a thumbnail, it becomes difficult for the user to view the thumbnail display if it is registered too much in the database. Therefore, by restricting database registration, it becomes easier to see the thumbnail display of the list of target images.

(4) Thumbnail Display FIG. 8 is a diagram illustrating an example of the configuration of a recording / playback apparatus including a display unit and a thumbnail generation unit.

  In FIG. 8, reference numeral 800 denotes a second form of the recording / reproducing apparatus. In the second recording / reproducing apparatus 800, a display unit 801 and a thumbnail generating unit 802 are added to the first recording / reproducing apparatus 100 shown in FIG. Accordingly, the recording apparatus 800 includes a video data input unit 101, a video compression / decompression unit 102, an audio data input unit 103, an audio compression / decompression unit 104, a demultiplexing unit 105, a recording medium control unit 106, a recognition unit 107, and a recognition control unit. 108, a memory 109, a database management unit 111, a display unit 801, and a thumbnail generation unit 802.

The display unit 801 is a device that displays video such as a liquid crystal monitor. The video data expanded by the video compression / expansion unit 102 is displayed, or the thumbnail generated by the thumbnail generation unit 802 is displayed. The thumbnail generation unit 801 generates a thumbnail of video data recorded on the recording medium 110. A thumbnail usually indicates a reduced still image obtained by cutting out a video at the start of recording, but a function for generating a thumbnail using a video at a time when a target image is recognized can be applied by applying the present plan.
In this example, the display unit 801 is part of the recording / reproducing apparatus 800, but the display unit may be external. In that case, a video external output unit is provided instead of the display unit 800.

  FIG. 9 is a diagram showing a display unit displaying video data of the video input unit. The input video display screen 900 is a video displayed on the display unit 801.

  FIG. 10 is a diagram showing a display unit 801 that displays scenes recorded on the recording medium 110 as thumbnails.

  The disc navigation display screen 1000 displays a title bar 1001 at the top to distinguish it from the video data display from the video input unit shown in FIG. 9, and displays thumbnail images of scenes recorded on the recording medium 110 as the number of scenes. Only display. A scene selection frame 1002 indicates that the scene is currently selected. When the playback function of the recording / playback apparatus 800 is executed, the scene selected in the scene selection frame 1002 is played back on the display unit 801.

  In order to distinguish from the thumbnail display such as disc navigation shown in FIG. 10, a title bar 1101 is displayed at the top, and thumbnail images of scenes already recorded on the recording medium 110 are displayed by the number of scenes. A scene selection frame 1102 indicates that the scene is currently selected.

  The difference from FIG. 10 is that the thumbnail image to be displayed is not the top image of each scene, but the image when the recognition unit 107 first recognizes the target image when the scene is recorded is displayed as a thumbnail. The thumbnail image is generated by the thumbnail generation unit 802 at the time of the first thumbnail display, and is recorded in the database of the recording medium 110 via the database management unit 111.

  FIG. 12 is a diagram showing a display unit 801 that displays thumbnails when a face is recognized multiple times in a scene.

  A title bar 1101 is displayed at the top in order to distinguish it from the thumbnail display such as disc navigation shown in FIG. When the playback function of the recording / playback apparatus 800 is executed, playback is performed on the display unit 801 from the image selected in the scene selection frame 1202. That is, the playback is performed from the middle of a certain scene. Each thumbnail is an image when the target image is recognized, and since the time when this thumbnail is recognized is recorded in the database, it can be reproduced from the middle.

  FIG. 13 is a diagram showing a screen transition diagram displayed on the display unit 801. As shown in FIG.

  In the input video display state 1300, the video shown in FIG. In the disc navigation display state 1301, the disc navigation display shown in FIG.

In this state, when a disk navigation button of the recording / playback apparatus is pressed, the screen transitions to a disk navigation display 1301 (1310). On the contrary, when the disc navigation button is pressed in the state of the disc navigation display 1301, the screen transitions to the input video display state 1300 (1311). However, the screen transitions 1310 and 1311 are when the recognition function is turned off.

  When the recognition function is turned on, it is as follows.

  When the disc navigation button is pressed in the input video display state 1300, the screen transitions to the face thumbnail list display state 1302 (1312). On the other hand, when the disc navigation button is pressed in the face thumbnail list display state 1302, the screen transitions to the input video display state 1300 (1313).

  If the screen display button is pressed in the face thumbnail list display state, the screen transitions to the face index display state 1303 (1314). Conversely, when the screen display button is pressed in the face index display state 1303, the screen transitions to the face thumbnail list display state 1302 (1315), and when the disc navigation button is pressed, the screen transitions to the input video display state 1300 (1316).
