It is a control unit.

  The recording medium 13 is composed of, for example, a semiconductor memory, a hard disk, a flexible disk, a magneto-optical disk, a rewritable optical disk, or the like.

  The lens 1 forms an optical image of the subject on the imaging surface of the CCD image sensor 2. The CCD image sensor 2 converts the optical image formed by the lens 1 into an electrical signal. The A / D converter 3 converts the analog image signal output from the CCD image sensor 2 into digital video data and applies it to the CPU 5. The CPU 5 performs known camera signal processing such as gamma correction and color balance adjustment on the video data from the A / D converter 3. The CPU 5 supplies the video data from the A / D converter 3 to the signal processing unit 10, the recording / reproduction control units 12, 14 and / or the LCD / CVF control unit 7, and from the recording / reproduction control units 12, 14. Is supplied to the signal processing unit 10 and / or the LCD / CVF control unit 7. The CPU 5 also controls the entire video camera. The memory 4 stores various data required by the CPU 5 and is used as a work area for the CPU 5.

  The operation unit 6 is for operating the video camera body, and includes various switches and key groups such as a shooting start switch, a shooting end switch, a recording mode key, a playback mode key, and an association setting instruction key. In this embodiment, the operation unit 6 is used to input image size, image quality adjustment, position adjustment, and the like to the CPU 5.

  The LCD / CVF control unit 7 controls image display on the CVF 8 and the LCD 9. The recording / reproduction control unit 14 controls recording / reproduction of image data and its additional information on the magnetic tape 15. The recording / reproduction control circuit 12 controls recording / reproduction of image data and its additional information on the recording medium 13. The CPU 5 is a central processing unit that controls each part of the system of the video camera.

  The basic recording operation of this embodiment will be described. The CCD image sensor 2 converts an optical image of a subject by the lens 1 into an electric image signal. The A / D converter 3 samples the analog image signal output from the CCD image sensor 2 and converts it into digital video data. The CPU 5 performs basic processing on the digital video data from the A / D converter 3 in a video camera such as color separation, white balance, gamma correction, and aperture correction. The CPU 5 applies the digital video data thus processed to the recording / playback control unit 14, and the recording / playback control unit 14 records the digital video data from the CPU 5 on the magnetic tape 15.

  The shooting date and time is recorded on the magnetic tape 15 together with the video data. System data including shooting date and time is recorded in the subcode sector, video sector, and audio sector of the magnetic tape 15. FIG. 2 shows an example of the structure of one track of the magnetic tape 15. In the subcode sector, the shooting date and time is recorded as pack data shown in FIG.

  When the user designates the recording medium 13 as a recording destination, the CPU 5 adjusts the image size, image quality, position, and the like of the video data from the A / D converter 3 under the conditions designated by the operation unit 6. In accordance with the compression method and compression parameters set in step 1, the data is compressed by a predetermined compression method and applied to the recording / reproducing control unit 12. The compression method is, for example, JPEG (Joint Photographic Experts Group) or JPEG2000. On the recording medium 13, as additional information of the compressed image data, identification information for specifying the camera, image / audio recording setting information, shooting date and time, shooting conditions (aperture value, shutter speed, etc.), and the like are recorded. The CPU 5 outputs these additional information to the recording / playback control unit 12 together with the compressed image data.

  The recording medium 13 employs a DCF (Design rule for Camera File System) standard employed in an electronic still camera or the like. FIG. 4 shows an example of the arrangement of directories and data files in a data filing system according to the DCF standard.

  The recording / playback control unit 12 stores the compressed image data and its additional information from the CPU 5 as files on the recording medium 13 under file system management such as UDF (Universal Disc Format) or FAT (File Allocation Table). Write.

  Here, the file system means a structure system composed of management information and file data for managing individual files. By sharing a file system, data can be recorded / reproduced on different recording media or on different recording / reproducing apparatuses. The CPU 5 supplies the same data supplied to the recording / playback control unit 12 to the signal processing unit 10 as necessary, and supplies the uncompressed video data to the LCD / CVF control unit 7 for confirmation. The signal processing unit 10 processes data from the CPU 5 for output and applies it to the signal output unit 11. The LCD / CVF control unit 7 applies the image data from the CPU 5 to the CVF 8 and / or the LCD 9. Thereby, the user can confirm the image recorded on the magnetic tape 15 and / or the recording medium 13 on the screen of the CVF 8 and / or the LCD 9.

  Next, the reproducing operation of this embodiment will be described. When reproducing the image recorded on the magnetic tape 15, the recording / reproducing control unit 14 runs the magnetic tape 15 to read the recorded data, and supplies the reproduced data to the CPU 5. The CPU 5 separates the reproduction data from the recording / reproduction control unit 14 into image data and additional information, applies the former to the signal processing unit 10, and applies the latter to the LCD / CVF control unit 7. The signal processing unit 10 converts the image data from the CPU 5 into an analog signal and applies it to the signal output unit 11. Further, the LCD / CVF control unit 7 supplies the image data from the CPU 5 to the CVF 8 and / or the LCD 9 and displays an image on the screen of the CVF 8 and / or the LCD 9.

  The recording / playback control unit 12 plays back a specified file among the files recorded on the recording medium 13 and supplies the data included in the file to the CPU 5. The CPU 5 separates image information and additional information from the data from the recording / playback control unit 12. Since the image information is compressed from the data from the recording / playback control unit 12, the CPU 5 expands the compressed image data and applies the restored image data to the signal processing unit 10. The CPU 5 also applies additional information to the LCD / CVF control unit 7. The signal processing unit 10 converts the image data from the CPU 5 into an analog signal and applies it to the signal output unit 11. Further, the LCD / CVF control unit 7 supplies the image data from the CPU 5 to the CVF 8 and / or the LCD 9 and displays an image on the screen of the CVF 8 and / or the LCD 9.

  In this embodiment, the moving image is recorded on the magnetic tape 15 and the still image is compressed and recorded on the recording medium 13. Accordingly, when the user sets the moving image reproduction mode by the operation unit 6, the CPU 5 instructs the recording / reproduction control unit 14 to reproduce the recorded image on the magnetic tape 15 and its additional information. When the user sets the still image playback mode with the operation unit 6, the CPU 5 instructs the recording / playback control unit 12 to play back the recorded image on the recording medium 13 and its additional information. Of course, in the moving image playback mode, playback, fast forward, rewind, fast forward playback, rewind playback and stop of the magnetic tape 15 can be selected. In the still picture playback mode, playback of arbitrarily designated still picture data and sequential playback of a plurality of still picture data are possible.

  With reference to the flowchart shown in FIG. 5, an operation for reproducing a still image associated with a moving image during the reproduction of the moving image will be described.

  The CPU 5 reads the shooting date / time information of the moving image to be played back from the magnetic tape 15 by the recording / playback control unit 14 (S1) and stores it in the variable TAPE (S2). The CPU 5 searches the still image recorded on the recording medium 13 for a still image having the same shooting date as the moving image to be reproduced.

  Specifically, the CPU 5 starts reading the first still image file under the DCIM folder of the recording medium 13 by the recording / playback control unit 14 (S3), reads the shooting date / time data of this still image file (S4), The variable STILL is stored (S5). The CPU 5 compares the shooting date of the variable TAPE with the shooting date of the variable STILL and determines whether or not they match (S6). If the shooting date of the variable TAPE and the shooting date of the variable STILL are different (S6), it is determined whether there is a next still image file stored in the recording medium 13 (S7). If there is a next still image file, the shooting date / time data is stored in the variable STILL and compared with the shooting date of the variable TAPE (S6). If the shooting dates of all the still image files are checked (S7), the operation is terminated.

  When the shooting date of the variable TAPE and the shooting date of the variable STILL are the same (S6), the CPU 5 instructs the LCD / CVF control unit 7 to stand still on the screen of the LCD 9 that reproduces and displays the moving image as shown in FIG. The image icon is displayed (S8). The CCPU 5 further stores the still image file name corresponding to the shooting date of the moving image in the variable FILENAME (S9).

  As described above, when there is a still image recorded on the recording medium 13 during the reproduction of the moving image recorded on the magnetic tape 15 by the operation shown in FIG. By displaying the still image icon, it is possible to notify the user of the existence of a related still image.

  In step S6 shown in FIG. 5, whether or not the value of the variable TAPE and the shooting date of the variable STILL are the same as the determination condition, is the difference between the shooting date of the variable TAPE and the shooting date of the variable STILL within an arbitrary predetermined value? Even if the determination condition is used, the same effect is obtained. Such determination conditions include, for example, within several days before and after, within the same week, within the same month, within the same year, and the like.

  In addition, when the user sets composite display using the operation unit 6 on the association playback setting screen shown in FIG. 7, the CPU 5 controls the recording and playback of the still image file stored in the variable FILENAME by the operation shown in FIG. Reading from the recording medium 13 by the unit 12. The CPU 5 combines the image data of the still image file read from the recording medium 13 with the image data from the magnetic tape 15, and combines the combined image data with the signal output unit 11 via the signal processing unit 10 and / or. Then, the data is output to the CVF 8 or the LCD 9 via the LCD / CVF control unit 7. Thereby, as shown in FIG. 8, the related still image is reproduced and displayed on the reproduced and displayed moving image.

  It is assumed that a still image with the same shooting date as that of the moving image recorded on the magnetic tape 15 is recorded on the recording medium 13. In this situation, when the operation unit 6 is set to change from the reproduction mode of the magnetic tape 15, that is, the moving image reproduction mode, to the reproduction mode of the recording medium 13, that is, the still image reproduction mode, the variable is changed according to the operation shown in FIG. When a still image file stored in FILENAME is reproduced, a moving image of the same shooting date recorded on the magnetic tape 15 is reproduced.

  Next, with reference to the flowchart shown in FIG. 9, an operation of reproducing and displaying a related moving image while reproducing a still image will be described.

  The CPU 5 reads the shooting date of the still image file from the recording medium 13 via the recording / playback control unit 12 (S21), and stores it in the variable STILL (S22). The recording / reproducing control unit 14 rewinds the magnetic tape 15 (S23). When the magnetic tape 15 reaches the starting end (S24), the recording / reproducing control unit 14 fast-forwards and reproduces the magnetic tape 15 (S25). The operation of step S23 is repeated until the magnetic tape 15 reaches the starting end (S24).

  In the fast-forward playback state of the magnetic tape 15, the recording / playback control unit 14 reads shooting date information recorded as additional information on the magnetic tape 15 from the magnetic tape 15 (S26). The read photographing date information is stored in the variable TAPE (S27).

  It is determined whether the shooting date of the variable TAPE matches the shooting date of the variable STILL (S28). If the shooting date of the variable TAPE and the shooting date of the variable STILL are different (S28), it is confirmed whether the magnetic tape 15 is terminated (S29). If the magnetic tape 15 is terminated (S29), the magnetic tape 15 is stopped and the operation is terminated. If the magnetic tape 15 is not terminated (S29), the process returns to S25 and the fast-forward reproduction of the magnetic tape 15 is continued (S29).

  If the shooting date of the variable TAPE and the shooting date of the variable STILL are the same in S28, the CPU 5 displays the moving image icon shown in FIG. 8 on the screen of the LCD 9 (S30). Further, the recording / reproducing control unit 14 stops the magnetic tape 15 (S31).

  As described above, when the moving image having the same shooting date as the still image reproduced from the recording medium 13 is recorded on the magnetic tape 15 by the operation shown in FIG. As shown, the moving image icon is displayed on the still image playback screen.

  Further, in step S26 in FIG. 9, the determination condition is that the shooting date of the variable TAPE and the shooting date of the variable STILL are the same, but the difference between the shooting date of the variable TAPE and the shooting date of the variable STILL is an arbitrary predetermined value. The same effect can be obtained even if the following condition is used.

  Further, when the user sets the composite display by the operation unit 6 on the association playback setting screen shown in FIG. 7, the CPU 5 plays back the moving image from the magnetic tape 15 from the recording / playback control unit 14 by the operation shown in FIG. . The CPU 5 combines the moving image data reproduced from the magnetic tape 15 with the still image data from the recording medium 13, and combines the combined image data with the signal output unit 11 via the signal processing unit 10 and / or the LCD / The data is output to the CVF 8 or the LCD 9 via the CVF control unit 7. Thereby, as shown in FIG. 10, the related moving image is reproduced and displayed on the still image to be reproduced and displayed.

  When a moving image having the same shooting date as that of the still image recorded on the recording medium 13 is recorded on the magnetic tape 15, the playback mode (moving image playback) of the magnetic tape 15 is changed from the card playback mode (still image playback mode). When the mode is shifted to (mode), a moving image is reproduced from the portion of the shooting date that is the same as the shooting date of the still image in a series or a plurality of moving images recorded on the magnetic tape 15 by the operation shown in FIG. That is, it has a function of searching for and playing back a moving image using the shooting date as a key.

  As described above, while playing back a moving image on the magnetic tape 15, a still image associated with the shooting date is retrieved by searching a still image file with the same shooting date as the moving image being played from another recording medium. Files can be easily searched and presented to the user. Conversely, while playing back a still image file, a movie with the same shooting date as that of the still image file file is retrieved from the magnetic tape 15 and played back. Can be presented to the user.

  FIG. 15 is a flowchart showing the operation when reproducing the moving image of the embodiment shown in FIG. With reference to the flowchart shown in FIG. 15, the operation | movement at the time of the moving image reproduction of a present Example is demonstrated.

  The CPU 25 instructs the recording / playback control unit 32 to read the shooting date of the moving image file from the recording medium 33 (S41) and stores it in the variable MOVIE (S42). The CPU 25 searches for a still image having the same shooting date as the moving image to be reproduced from the still images recorded on the recording medium 33.

  Specifically, the CPU 25 starts reading the still image file under the DCIM folder of the recording medium 33 by the recording / playback control unit 32 (S43). The recording / playback control unit 32 reads the shooting date data of the still image file (S44) and stores it in the variable STILL (S45). The CPU 25 compares the shooting date of the variable MOVIE with the shooting date of the variable STILL, and determines whether or not the shooting date of the variable MOVIE matches the shooting date of the variable STILL (S46). If the shooting date of the variable MOVIE and the shooting date of the variable STILL are different (S46), it is determined whether there is a next still image file stored in the recording medium 33 (S47). If there is a next still image file, the shooting date data is stored in the variable STILL and compared with the shooting date of the variable MOVIE (S46). When the shooting dates of all the still image files are checked (S47), the operation is terminated.

  If the shooting date of the variable MOVIE is the same as the shooting date of the variable STILL (S46), a still image icon is displayed on the moving image playback screen as shown in FIG. 6 (S48). Further, the corresponding still image file name is stored in the variable FILENAME, and the operation is terminated (S49).

By displaying the still image icon, it is possible to notify the user of the existence of a related still image.

  Further, in step S46 shown in FIG. 15, it is determined whether or not the shooting date of the variable MOVIE and the shooting date of the variable STILL are the same. However, the difference between the shooting date of the variable MOVIE and the shooting date of the variable STILL is an arbitrary predetermined value. The same effect can be obtained by determining whether the value is less than or equal to the value.

  In addition, when the user sets composite display using the operation unit 26 on the association playback setting screen shown in FIG. 7, the CPU 25 records and plays back the still image file stored in the variable FILENAME by the operation shown in FIG. 32 from the recording medium 33. The CPU 25 combines the still image read from the recording medium 33 with the image data from the moving image file, and combines the combined image data to the signal output unit 31 via the signal processing unit 30 and / or the LCD / CVF control unit 27. To the CVF 28 or the LCD 29. As a result, as shown in FIG. 16, a still image with the same shooting date or an approximate shooting date is superimposed and displayed on the reproduced moving image.

  The CPU 25 reads the shooting date of the still image file from the recording medium 33 via the recording / playback control unit 32 (S61), and stores it in the variable STILL (S62). Next, the CPU 25 starts reading the moving image file under the DCIM folder of the recording medium 33 via the recording / playback control unit 32 (S63), reads the shooting date data of the moving image file (S64), and sets the moving image in the variable MOVIE. The shooting date of the file is stored (S65).

  It is determined whether or not the shooting date of the variable MOVIE coincides with the shooting date of the variable STILL (S66). If the shooting date of the variable MOVIE is different from the shooting date of the variable STILL (S66), steps S64, S65, and S66 are repeated until all moving image files stored in the recording medium 33 have been examined (S67).

  If the shooting date of the variable MOVIE is equal to the shooting date of the variable STILL in step S66, the CPU 25 displays a moving image icon on the still image playback screen as shown in FIG. 8 (S68). Further, the moving image file name of the same shooting date is stored in the variable FILENAME, and the operation is terminated (S69).

  As described above, when still images and moving images on the same shooting date are recorded on the recording medium 33 by the operation shown in FIG. 17, the moving images on the same shooting date are detected during playback of the still image file on the recording medium 33. The user can be notified by the moving image icon display as shown in FIG.
