| Abstract: | In this paper, analog video signal losses and shifts after long distance transmission is discussed. Software auto calibration is proposed to resolve the above-mentioned problem. A calibration pattern is sent from the video source and analyzed, and then the gain and offset parameters of video ADC is adjusted to obtain a best calibration of brightness and contrast. |
