Selection device for electronic endoscope system; has switching control processor for video-signal and synchronization signal switching processors to output video signals from two endoscopes

摘要

The device has a video-signal switching processor to output video signals from first and second endoscopes to a peripheral unit. A synchronization signal switching processor outputs synchronization signals to the peripheral unit from the two endoscopes. A switching control processor controls the two switching processors, so that the video signal output is blocked for a fixed time after controlling the synchronization signal switching processor.
