Abstract: A parallax information generation device includes: a phase image generation unit that generates a relative phase image from phase shift images based on projection of phase shift pattern light; a code image segmentation processing unit that performs segmentation for each period of the phase shift pattern light on the basis of a sequence generated from a code value given to each pixel of binary pattern images based on projection of binary pattern light; and a parallax information generation unit that generates parallax information on the basis of the relative phase image and results of the segmentation. The binary pattern light is constituted by a sequence in which 2n mutually different code values are allocated by combining n kinds of binary pattern light, and mutually different code values are allocated at each boundary between periods of the phase shift pattern light.
