Document Type and Number:
WIPO Patent Application WO/2021/131921
Kind Code:
A1
Abstract:
A single solid-state imaging element (92) is disposed with respect to a first optical system (38) and a second optical system (72) provided to a rigid endoscope (12). A first image (60) formed by a first light beam (96) emitted from an observation object (58) via the first optical system (38) and a second image (74) formed by a second light beam (98) emitted from the observation object (58) via the second optical system (72) are formed on an imaging surface (92A) of the solid-state imaging element (92). The solid-state imaging element (92) converts the first image (60) and the second image (74) into electrical signals. On the basis of the electrical signals from the solid-state imaging element (92), a first picture (132) corresponding to the first image (60) and a second picture (134) corresponding to the second image (74) are displayed on a display surface (128A) of a picture display unit (128).
