Patent ID: 7567300

Claim:
A video signal processor that receives luminance input signal data and color difference input signal data as consecutive frames of video data and generates luminance output signal data and color difference output signal data, comprising: a first video data memory that receives the luminance output signal data, stores the received data for one frame interval, and outputs the stored data as the first delayed data; a luminance motion detector that takes a first absolute difference between the luminance output signal data and the first delayed data, compares the first absolute difference with at least one luminance difference threshold, and outputs a luminance motion signal indicating a result of the comparison; and a cross-color rejection section that stores the color difference input signal data for at least one frame interval to obtain delayed color difference data, takes an average of the color difference input signal data and the delayed color difference data to obtain averaged color difference data, and combines the color difference input signal data and the averaged color difference data according to at least the luminance motion signal to obtain the color difference output signal data.
