1. a camera system, be disposed near described camera system with the light-emitting device that alternating current drive signal drives, described camera system comprises:

  • Frame of video drive signal generation unit, the N number of cycle for the synchronizing signal of the actual drive signal every described light-emitting device produces a frame of video drive singal, wherein, N be more than or equal to 1 integer;

    AndIMAQ generation unit, for gathering frame of video to produce video in response to described frame of video drive singal;

    Synchronizing signal generation unit, for generation of synchronizing signal for subsequent use, the ideal frequency of the synchronizing signal of the actual drive signal of described synchronizing signal for subsequent use and described light-emitting device is with frequently;

    Detecting signal unit, whether luminous for detecting described light-emitting device;

    AndDrive singal selected cell, when described detecting signal unit detects described light-emitting device luminescence, the synchronizing signal of described actual drive signal is supplied to described frame of video drive signal generation unit, and when described detecting signal unit does not detect described light-emitting device luminescence, described synchronizing signal for subsequent use is supplied to described frame of video drive signal generation unit, whereinDescribed frame of video drive signal generation unit counted the cycle of the synchronizing signal of the actual drive signal that described drive singal selected cell provides or the cycle of synchronizing signal for subsequent use.
