3d endoscope device

Abstract

In the present invention, an endoscope scope is provided with a left-eye optical system and a right-eye optical system that form an image with light corresponding to a left-eye image and a right-eye image, and is provided with a CMOS sensor on which first light and second light obtained through the left-eye optical system and the right-eye optical system are formed into separate images on a single light receiving surface. A straight line that connects the center of a first image and the center of a second image formed on the light receiving surface of the CMOS sensor is orthogonal to the parallax direction. On the light receiving surface of the CMOS sensor, a first region in which the center of the first image and the second image are formed is divided into a plurality of first divided regions, and a second region is divided into a plurality of second divided regions. When the CMOS sensor reads data constituting image signals from the first region and the second region, the CMOS sensor reads data by alternating scanning a first divided region at a position corresponding to the left-eye image and a second divided region at a position corresponding to the right-eye image.

Description

technical field [0001] The present invention relates to a three-dimensional endoscope device for imaging left-eye / right-eye images on a single MOS sensor. [0002] This application claims priority based on Japanese Patent Application No. 2011-226756 for which it applied in Japan on October 14, 2011, and uses the content here. Background technique [0003] There is a three-dimensional endoscope device that realizes stereoscopic vision by imaging left-eye / right-eye images with parallax on a single MOS sensor. Due to the installation space of the scope of the endoscope, it is more preferable to use a single image pickup element whose light receiving surface has a shape close to a square to form a left-eye / right-eye image rather than a plurality of image pickup elements. [0004] When forming an image for the left eye and an image for the right eye on a single imaging element, they are usually formed on areas obtained by dividing the light receiving surface of the imaging eleme...

AI Technical Summary

Problems solved by technology

Therefore, in the method of imaging on the area obtained by dividing the light-receiving surface of the nearly square image sensor into left and right, the image must be enlarged in the horizontal direction at a large magnification afterward, which is a cause of deterioration in image quality.
