Abstract:
An apparatus for calibrating an audio-visual (AV) signal includes a controller for generating a control signal, a controllable filter for selectively filtering the AV signal in response to the control signal to output either the AV signal or a filtered AV signal; and a calibrator for generating a group of calibrating coefficients according to the filtered AV signal and calibrating the AV signal according to the group of calibrating coefficients.
