Patent abstract
The present invention provides an adaptive Y/C separation circuit for video signal processing that is capable of correcting previous color discrepancy in separating the luminance (Y) and chrominance (C) signals from the color video signals. In the process, the correlation of video signals on referencing scanning lines is analyzed by transposing the chrominance signals onto a two-dimensional UV plane. A correlation coefficient is obtained through the analysis for adjusting the video signals in the direction of the actual chrominance level, thus separating the luminance and chrominance signals with relatively low cost circuit implementation.
