Abstract
A stereoscopic electronic endoscope device comprises an electronic endoscope with an image pickup device having a solid-state image sensor located at the tip part of an inserting part and an optical imagery system for creating an image of a shooting object on said solid-state image sensor and enabling observation at two positions where stereoscopic view is possible, an image signal processing device for processing an output signal of said image pickup device, and a stereoscopic image forming device that forms a stereoscopic image of the shooting object using an image signal generated by said image signal processing device based on each output signal of said image pickup device at two positions.
