摘要: High frequency components of a video signal are attenuated for avoiding aliasing when the is corrected by non-linear gamma correction circuit. Such high arise from harmonics, and also generated in image contour processing signal. The band limited, thereby linearizing circuit preventing aliasing. Up-converting sampling increases desired limitation area defers generation that cause function divided into plurality sections which replaced respective straight-line segments each represented linear expression, effected with segment corresponding to amplitude digital
