    • A video signal processor for improving a detection precision of Y motion and C motion, preventing erroneous judgment, and preventing deterioration of image quality without being influenced by the band of the luminance signal or the phase of a sub-carrier of chroma. The processor includes a provisional 3D Y/C separation motion detection circuit, extracting Y signals of a current frame and a past frame based on composite video signals of three adjacent lines of the current frame and the past frame, detecting Y motion in accordance with a difference of Y signals of the current frame and the past frame by a Y motion detection unit, outputting a Y motion detection signal MVDy, detecting C motion by a C motion detection unit based on Y signals of three adjacent lines in the current frame, outputting a C motion detection signal MVDc, and selecting, according to the motion detection signals MVDy and MVDc, the difference of the C signals separated from the current frame and the past frame or a predetermined value 0 to generate a C motion coefficient.
    • 一种视频信号处理器,用于提高Y运动和C运动的检测精度,防止错误判断,并且防止图像质量的劣化,而不受亮度信号的频带或色度子载波的相位的影响。 处理器包括临时3D Y / C分离运动检测电路,基于当前帧和过去帧的三个相邻行的合成视频信号,提取当前帧和过去帧的Y信号,根据 通过Y运动检测单元将当前帧和过去帧的Y信号的差分输出Y运动检测信号MVD ,基于三维运动检测单元的Y信号,由C运动检测单元检测C运动 当前帧中的相邻行,输出C运动检测信号MVD< C>,并且根据运动检测信号MVD< Y>和MVD< C< >,与当前帧和过去帧分离的C信号的差值或预定值0,以产生C运动系数。
