    Abstract: A camera module according to an embodiment of the present invention includes a lighting unit configured to output an incident light signal to be emitted to an object, a lens unit configured to concentrate a reflected light signal reflected from the object, an image sensor unit configured to generate electric signals from the reflected light signal concentrated by the lens unit, a tilting unit configured to shift an optical path of at least one of the incident light signal and the reflected light signal for each image frame in units of subpixels of the image sensor unit, and an image control unit configured to extract depth information of the object using a phase difference between the incident light signal and the reflected light signal. The image control unit includes an image controller configured to extract the depth information having a higher resolution than a plurality of subframes generated using the electric signals on the basis of the subframes.
