Abstract
The endoscope signal processing apparatus is provided with a first signal processing device processing the signal for a field sequential type imaging device and a second signal processing device processing the signal for a synchronous type imaging device. One signal processing device has a circuit partly used in common with the other signal processing device. Both signal processing device have a common video signal output end from which video signals from both signal processing devices are output. This apparatus is further provided with a discriminating device discriminating the imaging system of the endoscope to be connected and an output switching device whereby the video signal transmitted through the video signal processing device corresponding to the imaging system discriminated by this discriminating device is led selectively to the common video signal output.
