Each of the three electronic endoscopes 30, 40, and 50 outputs an image signal for each color (R, G, B) to the video switcher 18. In addition, each of the electronic endoscopes 30, 40 and 50 has terminals 32, 42 and 52 and foot switches 34, 44 and
54 are attached.

Each of the terminals 32, 42, and 52 has an operation unit. By operation of the operation unit, a search request signal SRQ, information such as date, patient name, doctor name (hereinafter, referred to as ID information) and a machine number information are multiplexer-multiplexed. 29,
Input to the server personal computer 10 via the bus line 28 and the interface 26, the foot switches 34, 44, 54 are respectively operated when capturing a still image, and the recording command signal is transmitted together with the machine number information via the parallel I / O port 25. It can be input to the server personal computer 10.

The search personal computer 12 can independently search data recorded on the multi-user hide disk 24, and outputs a search request signal SRQ and image number information to the server personal computer 10 when an image is to be viewed. The server personal computer 10 mainly controls and controls the writing and reading of image signals, and is usually in a recording mode.
4.Enter the recording command signal from 54, 54
Check whether the search request signal SRQ from 2 has been input. When a recording command signal is input from one of the foot switches, the video switcher 18 is switched to capture an image signal from the electronic endoscope corresponding to the foot switch, and the optical disk controller 16 is controlled to control the component coder 15 and the time. Base collector 17
An image signal input through the optical disc deck 14 is recorded on the optical disc in the optical disc deck 14. The component coder 15
The RGB image signal is converted into a luminance signal Y and a chroma signal C, and the time base collector 17 performs phase matching based on the synchronizing signal to prevent image fluctuation.

Further, when the server PC 10 receives a search request signal SRQ or the like from the search personal computer 12, the server PC 10 enters a reproduction mode, controls the optical disk controller 16 to read out a necessary image signal, and stores the image signal in the frame memory 20. After that, the recording mode is set again.

The image signal stored in the frame memory 20 is output to a color monitor 22 via a two-channel switch 21 so that the image requested by the search personal computer 12 is displayed.
