CIRCUIT FOR VIDEO MOIRE REDUCTION

摘要

A method and device for reducing moiré by preventing the production of the second harmonic of the video signal Nyquist frequency. A nonlinear function (10) is applied to one of a) a digital video signal having a nonlinearity between an electrical video signal and luminance, and b) an analog video signal to create an output signal having a linearity between the electrical signal and luminance. The output signal is displayed on a display (1) having a linearity between the electrical signal and luminance.
