Patent ID: 7081916

Claim:
An electronic endoscope selector comprising: a video signal switching processor that switches video signals, which are output to at least one peripheral device, from first video signals fed from a first electronic endoscope to second video signals fed from a second electronic endoscope; a synchronizing signal switching processor that switches synchronizing signals, which are output to said peripheral device, from synchronizing signals fed from said first electronic endoscope to synchronizing signals fed from said second electronic endoscope, wherein said synchronizing signal switching processor completes synchronization of the synchronizing signals before said video signal switching processor outputs the video signals to said peripheral device; and a switching control processor that drives said video signal switching processor and said synchronizing signal switching processor, and suspends output of said video signals for a predetermined period while the switched synchronizing signals are output, the predetermined period being longer than the time required for the synchronizing signal to synchronize with said peripheral device.
