Abstract
A 3D depth camera module, including a light transmitting portion having a laser for emitting light, and having a diffractive optical element for passing the light therethrough such that the light reaches a subject with a preset pattern; a light receiving portion configured to receive the light reflected from the subject; an analyzing portion configured to analyze a 3D shape of the subject, based on a shifted degree of the reflected light; and an operating portion configured to move part of the light transmitting portion such that a position of one region of the subject where the light reaches is changed. Further, the operating portion moves at least part of the light transmitting portion by a predetermined length being set to restrict repetitive arrival of the light onto one region of the subject; the diffractive optical element includes a plurality of spots spaced from each other by a predetermined spaced interval between two adjacent spots of the diffractive optical element; and the predetermined length is smaller than the predetermined interval.
