Abstract

A 3-dimensional (3D) image acquisition apparatus and a method of calculating depth information in the 3D image acquisition apparatus, the 3D image acquisition apparatus including: an optical modulator for modulating light reflected from a subject by sequentially projected N (N is 3 or a larger natural number) light beams; an image sensor for generating N sub-images by capturing the light modulated by the optical modulator; and a signal processor for calculating depth information regarding a distance to the subject by using the N sub-images.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2011-0109431 filed on Oct. 25, 2011, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present disclosure relates to a three-dimensional (3D) image acquisition device and a method of calculating depth information in the 3D image acquisition device. Background technique [0004] Recently, the importance of three-dimensional (3D) content has been emphasized according to the development and increase in demand of 3D display devices for displaying images with a sense of depth. Therefore, research into 3D image acquisition devices such as 3D cameras in which users themselves create 3D content is ongoing. Such a 3D camera is expected to obtain depth information in addition to existing 2D color image information in one shot. [0005] Depth information about the distance between the surface of the o...
