Abstract

PURPOSE:To separate a luminance signal and a chrominance signal in a good state by calculating plural at arithmetic values based on/the respective input and output values of plural delay means and the level of a video signal at present time, selecting one of the arithmetic values according to a correlation and extracting the chrominance signal included in the video signal of the present time by the use of this arithmetic value. CONSTITUTION:The plural delay means 201, 202, a deciding means for deciding the correlation based on the respective input and output values of the plural delay means 201, 202 and the level of the video signal of the present time, a selecting means S1 for selecting one of the plural arithmetic values according to the decision result of the deciding means and extracting means 208, 209 for extracting the chrominance signal and the luminance signal included in the video signal of the present time by the use of the selected arithmetic value are disposed. Thereby, the chrominance signal and the luminance signal are extracted from the video signal by the use of the arithmetic value the highest in the correlation to the video signal of the present time and the chrominance signal and the luminance signal can be separated from the video signal without deteriorating the picture quality of a cross color and a cross luminance.
