DEPTH CAMERA, MULTI-DEPTH CAMERA SYSTEM AND METHOD OF SYNCHRONIZING THE SAME

摘要

A depth camera includes a sensor unit receiving a reflected light and in response thereto outputting an electrical sensing signal; and a synchronization information calculation unit calculating a performance index with reference to the sensing signal, and with reference to the performance index, generating synchronization information for synchronizing a demodulation clock for sensing the received reflected light. The sensor unit adjusts the frequency and/or phase of the demodulation clock with reference to the synchronization information.
