    • An apparatus for correcting a color error, including: a color error detection unit for detecting the presence or absence of a color error in an edge region of an input video, based on a relation between difference values between interlaced horizontal lines and difference values between non-interlaced horizontal lines of chrominance and luminance signals, respectively; a correction unit for correcting the color error by performing chroma filtering on the chrominance signals of the input video, if the color edge is present in the edge region; and a control unit for controlling the chrominance signals to be outputted after being corrected if the color error is present in the edge region, and for controlling the input chrominance signals to be outputted as they are if the color error is not present in the edge region.
    • 一种用于校正颜色误差的装置,包括:颜色误差检测单元,用于基于隔行水平行之间的差值与非隔离度之间的差值之间的关系来检测输入视频的边缘区域中是否存在颜色误差; 色度和亮度信号的交错水平线; 校正单元,用于如果边缘存在于边缘区域中,则通过对输入视频的色度信号执行色度滤波来校正色差; 以及控制单元,用于如果颜色误差存在于边缘区域中,则在校正后控制输出的色度信号,并且如果边缘区域中不存在颜色误差,则控制输入色度信号被原样输出 。
