Stereoadapter, pattern projection adapter, and adapter for light-emitting member

摘要

A stereoadapter is mounted in front of an imaging optical system of a camera to photograph a parallax image. An optical system has two light-receiving modules spaced apart from each other by a predetermined distance to receive light from the same object. Then, the optical system directs light received by each of the two light-receiving modules to the imaging optical system of the camera. A light-emitting module is provided at a predetermined position associated with the optical system and can emit light for illuminating the object.
