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.
