Abstract:
1. A stereo adapter which is mounted in front of an imaging optical system of a camera to photograph a parallax image of object and an image including information on at least one of color tone and contrast of the object, the stereo adapter comprising: an optical system which has two light-receiving modules provided so as to be spaced apart from each other by a predetermined distance in a direction of a base line to receive light from the object and which direct the received light from each of the two light-receiving modules to the imaging optical system of the camera; a pattern projection module which projects a predetermined pattern onto the object when taking a photograph to obtain distance information on the object; and a light-emitting module which emits right for illuminating the object with light having no pattern when taking a photograph to obtain information one at least one of color tone and contrast of the object; wherein the light-emitting module d the pattern projection module are provided in a space between the two light-receiving modules such that a shadow of the object formed by light having no pattern from the pattern projecting module and shadow of the object formed by pattern projection from the pattern projecting module are formed in an occlusion area caused when the parallax image is photographed.
