    • A simplified Y/C separation circuit in which, a plurality of luminance signals are calculated for the subject pixel based on an NTSC signal of the subject pixel and NTSC signals of pixels that are close to the subject pixel spatially or temporally. Correlations between the plurality of luminance signals are obtained in a difference circuit and a comparison circuit. In a classification circuit, classification is performed, that is, the subject pixel is classified as belonging to a certain class, based on the correlations between the plurality of luminance signals. Prediction coefficients corresponding to the class of the subject pixel are read out from a prediction coefficients memory section. The RGB luminance signals of the subject pixel are then determined by calculating prescribed linear first-order formulae.
    • 一种简化的Y / C分离电路,其中,基于对象像素的NTSC信号和在空间上或时间上接近被摄体像素的像素的NTSC信号,针对被摄体像素计算多个亮度信号。 在差分电路和比较电路中获得多个亮度信号之间的相关性。 在分类电路中,基于多个亮度信号之间的相关性,进行分类,即,将被摄体像素分类为属于某一类别。 从预测系数存储部读出与被摄体像素的类别对应的预测系数。 然后通过计算规定的线性一阶公式来确定目标像素的RGB亮度信号。
