Abstract
An electronic endoscope is provided with a photoelectrically converting solid state imaging device and a light guide transmitting an illuminating light. A video signal processing circuit processes signals for the solid state imaging device. The electronic endoscope, the light guide and the video signal processing circuit are selectively connected and have a first light source and second light source for supplying different illuminating lights, respectively. Where the two light sources receive synchronizing signals from the video signal processing circuit and synchronized each other, the two light sources can supply the illuminating lights to a light guide. When the connection of the light guide is changed, the disorder of a picture image can be reduced.
