1. An apparatus for generating a depth image, the apparatus comprising:

  • an optical modulator which optically modulates reflective light which is reflected light from an object to which light modulated using a first pseudorandom (PN) sequence is irradiated, by use of second PN-sequences, each of which has a same PN sequence as the first PN-sequence, but the second PN-sequences having N different time shifts;

    an optical sensor which senses the optically modulated reflective light; and

    a depth image process unit which samples N intensity images from the optically modulated reflective light sensed by the optical sensor and generates a depth image of the object using the sampled N intensity images.
