Abstract:
1. A video signal converter comprising: a target pixel setting unit operable to set a target pixel in an input video signal; a position parameter feeding unit operable to feed a position parameter depending on a position of the target pixel set by said target pixel setting unit; a characteristic amount calculating unit operable to calculate a characteristic amount of the input video signal; a detection-threshold setting unit operable to set a detection threshold, based on the characteristic amount calculated by said characteristic amount calculating unit; a compensation parameter setting unit operable to determine a compensation parameter, based on the position parameter fed by said position parameter feeding unit and on the detection threshold set by said detection-threshold setting unit; and a conversion unit operable to convert a signal of the target pixel set by said target pixel setting unit in the input video signal, based on the compensation parameter determined by said compensation parameter setting unit, thereby outputting a conversion result, wherein said detection-threshold setting unit sets the detection threshold such that the detection threshold becomes smaller when the characteristic amount becomes bigger.
