  Step S206 functions as a transmission unit that transmits the representative video data generated by the generation unit to the corresponding recording medium so as to be stored in the non-contact memory 118.

  In the recording medium 112, the transmitted representative image data is stored in the non-contact memory 118 from the contact communication processing unit 114 via the non-contact communication processing unit 117.

  If it is determined in step S201 that the medium is not a compatible medium, image recording is started in step 202, image data is generated in step 203, and image data is transmitted for storage in a recording medium in step 205. Media processing.

  FIG. 3 is a flowchart showing the procedure of the second example of the image photographing / transmission process executed by the video recording apparatus in FIG.

  In a state where the recording medium 112 is recognized, first, in step S301, it is confirmed whether the medium is compatible with both non-contact and contact type access. If it is a compatible medium, control data is transmitted to the recording medium 112 in step S302.

  In the control data, when image data is transmitted from the video recording apparatus 101 and stored in the contact memory 115, processing for copying and storing the representative image data in the non-contact memory 118 is described.

  In step S302, when the determination unit determines that the recording medium is the corresponding recording medium, the control data instructing to store the representative video data of the video data stored in the contact memory 115 also in the non-contact memory 118 is stored in the corresponding recording medium. It functions as a first transmitting means for transmitting.

  Thereafter, when an image capturing instruction is received in step S303, the process proceeds to step S304, in which the image signal from the CCD 103 is converted into a video signal by the video signal processing circuit 104, and image data is generated.

  In step S305, the generated image data is transmitted to the recording medium 112 by contact-type access.

  Step S305 functions as a second transmission unit that transmits the video data generated by the generation unit to the corresponding recording medium.

  On the recording medium 112 side, in accordance with the control data transmitted in the previous step S302, the data is transmitted from the contact communication processing unit 114 of the recording medium 112 to the non-contact memory 118 via the non-contact communication processing unit 117. A part of image data (representative image data) is stored.

  If it is determined in step S301 that the medium is not a compatible medium, the image is simply captured in steps from step S303, and the process proceeds to steps S304 and S305 to transmit image data.

  FIG. 4 is a flowchart showing a procedure of image data reception processing executed by the recording medium in FIG.

  In step S 401, control data from the video recording apparatus 101 is received and stored in the contact memory 115. Next, when image data is received in step S402, it is determined in step S403 whether or not the image data received in step S402 is a copy target in accordance with the previously stored control data.

  If it is a copy target, the image data is stored in the non-contact memory 118 in step S404, and the image data is stored in the contact memory 115 in step S405.

  In step S403, when the received data is not image data or the like, if it is not the data to be copied designated by the control data, the process proceeds from step S403 to step S405, and the image data is only stored in the contact memory 115. It is.

  If the recording medium 112 is inserted into the video recording apparatus 101 in step S501, it is determined in step S502 whether the medium is compatible with both non-contact and contact-type access.

  If it is a compatible medium, representative image data is generated in step S503, and the representative image data is stored in step S504. Thus, when the recording medium 112 is inserted into the video recording apparatus 101, the representative image can be stored in the non-contact memory 118 of the recording medium 112 without performing photographing.

  The representative image data is obtained by using the time information of the recorded image data, using the final image data, using the top image data, or image data obtained by processing the original image data such as a thumbnail image. It is possible to use.

  FIG. 6 is a flowchart showing the procedure of the initialization process of the recording medium in FIG.

  In step S601, it is determined whether the recording medium 112 is a medium that supports both non-contact and contact-type access. If it is a compatible medium, the recording medium 112 is initialized in step S602.

  In step S603, image non-recording information indicating that no image is recorded is generated. Thereafter, in step S604, the non-image recording information is stored in the non-contact memory 118 of the recording medium 112.

  FIG. 7 is a flowchart showing the procedure of the recording medium content confirmation process in FIG.

  In step S701, the recording medium 112 is detected by non-contact communication and data communication is performed.

  Step S701 functions as detection means for detecting the corresponding recording medium by non-contact access.

  In step S702, it is determined whether the received data includes representative image data.

Step S702 functions as a second determination unit that determines the presence or absence of representative video data stored in the non-contact memory 118 when a corresponding recording medium is detected by the detection unit.

  If there is representative image data, the representative image data is displayed on the LCD 107 in step S703.

Step S703 functions as a display unit that displays the representative video data when the second determination unit determines that the representative video data is stored in the non-contact memory 118 .

  If there is no representative image data, it is determined in step S704 whether there is image non-recording information. If there is no image recording information, a message indicating that there is no image is displayed on the LCD 107 in step S705.

  If there is no image non-recording information, since the recording medium 112 has not been inserted into the video recording apparatus 101 before, a message indicating that the content is not supported and is not known is displayed on the LCD 107 in step S706. .
