Abstract: Disclosed according to an embodiment is a method for controlling emitted light in a camera module which can acquire depth information. More particularly, disclosed is a camera module for controlling delay time of light emitted from each of light sources to determine the direction of light emitted from the light sources. A camera module according to an embodiment may control delay time of light emitted from each of light sources so that the camera module can be operated with higher performance even from a long distance.

Abstract: According to one embodiment, disclosed is a method by which a camera module capable of acquiring depth information controls the output time point and the reception time point of light. By controlling both the output time point and the reception time point of light, the camera module can acquire the light of phases in which adjacent reception pixels differ from one another despite controlling light sources or reception pixels in line units.
