Motion adaptive luminance signal and color signal separating filter |
摘要 |
A filter is used for separating a color signal and a luminance signal from a composite color television signal in which the frequency of the color signal is multiplexed in a high-frequency region of the luminance signal. In response to the movement of a picture, an appropriate filter is selected from a filter utilizing interframe correlation, a filter utilizing interfield correlation and a filter utilizing the infield correlation. A plurality of filters utilizing filed correlation are prepared and a color signal and a luminance signal are separated by the processing of a principal pixel, which is an object of processing, and pixels different from each other. A filter is selected in accordance with the correlation state between the principal pixel and the pixels therearound.
