Claim Text:
1. A 3-dimensional (3D) image acquisition apparatus comprising: an optical modulator which modulates light reflected from a subject by sequentially projected N light beams; an image sensor which generates N sub-images by capturing the light modulated by the optical modulator; and a signal processor which calculates depth information corresponding to a distance to the subject by using the N sub-images, wherein N is a natural number that is greater than or equal to 3, and wherein the image sensor is exposed during a projecting time of each light beam of the N light beams to capture the modulated light and forms the N sub-images during at least a portion of a remaining time of the projecting time of each light beam of the N light beams.
