ABSTRACT:
A video signal converter has a target pixel setting unit which sets up a position of a target pixel of an input video signal, a position parameter feeding unit which supplies a position parameter depending on the position of the target pixel set by the target pixel setting unit, and a characteristic amount calculating unit which calculates a characteristic amount of the input video signal. The video signal converter also has a detection-threshold setting unit which sets up a detection threshold based on the characteristic amount calculated by the characteristic amount calculating unit, a compensation parameter setting unit which determines a compensation parameter based on the position parameter supplied by the position parameter feeding unit and the detection threshold set by the detection-threshold setting unit, and a multiplier which converts a signal of the target pixel set by the target pixel setting unit in the input video signal, based on the compensation parameter determined by the compensation parameter setting unit, and outputs the conversion result.
