Abstract
A video signal processing system capable of adjusting errors and related methods are introduced. The video signal processing system and related calibration methods utilize the characteristic of periodic breaks of video signals to perform various kinds of calibrations including gain calibration of ADC, offset calibration of ADC, dc-level shifting of input signals, and quatization errors spreading by adding analog random signals to input video signals. The required high accuracy in video signal processing systems is achieved in the present invention with the claimed calibration methods.
