If the image signal recorded on the recording medium 27 is a moving image, the first image in each moving image or an image when a predetermined time has elapsed is displayed as a thumbnail image.

  Specifically, the recording medium 27 compresses and records the thumbnail image information of each image signal together with the compressed image signal, and the control unit 10 displays as many thumbnail images as the number displayed on the selection screen 22a. Information is read from the recording medium 27 and temporarily stored in the third SDRAM 13. The control unit 10 sequentially decompresses the read thumbnail image information by the image compression / decompression unit 19 and stores it in the first SDRAM 18 to generate screen information that can display the selection screen 22a as shown in FIG. The generated screen information is displayed on the image display unit 22 via the display interface 21 at a predetermined timing. The selection screen 22a displays a list of thumbnail images of image signals recorded on the recording medium 27, so that the user can easily select a desired image signal.

  Below, the usage form in the display apparatus system 100 which consists of the digital camera 1 and the liquid crystal television 3 of the structure mentioned above is demonstrated. In the display device system 100 configured as described above, for example, the liquid crystal television 3 simultaneously receives an analog broadcast signal and a digital broadcast signal, and simultaneously displays a broadcast program based on the analog broadcast signal on the image display unit 22 of the digital camera 1. A usage form in which a broadcast program based on a digital broadcast signal is displayed on the display unit 43 of the liquid crystal television 3 is possible. Below, operation | movement of the digital camera 1 and the liquid crystal television 3 in such a usage form is demonstrated.

  In the display device system 100, the control unit 10 of the digital camera 1 and the control unit 30 of the liquid crystal television 3 receive the analog broadcast signal and the digital broadcast signal simultaneously by the liquid crystal television 3 by the operation of the operation units 11 and 31 by the user.

  The digital camera 1 can also record the video signal acquired from the liquid crystal television 3 on the recording medium 27. In this case, the control unit 10 compresses and decompresses the video signal stored in the first SDRAM 18 into an image. A predetermined compression process is executed by the unit 19 and once stored in the third SDRAM 13, after adding header information, it is recorded on the recording medium 27. Thus, by compressing the video signal to be recorded on the recording medium 27 of the digital camera 1, the data amount of each video signal can be reduced.

  On the other hand, the liquid crystal television 3 that has received the analog broadcast signal and the digital broadcast signal simultaneously displays the broadcast program based on the analog broadcast signal on its display unit 43, and simultaneously displays the broadcast program based on the digital broadcast signal on the digital camera 1. In the case of displaying on the unit 22, the signal processing unit 35 performs predetermined signal processing on the analog video signal acquired by the analog tuner 34 and causes the display unit 43 to display the signal at a predetermined timing. At the same time, a digital video signal acquired by the digital tuner 47 is sent from the camera connection connector 50 to the digital camera 1, and the digital video camera 1 performs a predetermined expansion process on the acquired video signal by the image compression / expansion unit 19.
