DEPTH CAMERA, MULTI-DEPTH CAMERA SYSTEM, AND SYNCHRONIZING METHOD THEREOF

摘要

PURPOSE: A depth camera is provided to improve the accuracy of a depth image, to reduce a blind spot of an image and to reduce power consumption of a light source. CONSTITUTION: A sensing unit receives reflective light and outputs as a sensing signal (S110). The sensing unit controls a frequency or phase of a demodulation clock with reference to fed back synchronization information (S140). A synchronization information calculation unit calculates a performance indicator with reference to the sensing signal and generates synchronization information of the demodulation clock for sensing the reflective light with reference to the performance indicator.
