Abstract
PURPOSE:To obtain an better image by providing a YC separation part following plural YC separation systems and selecting the most proper YC separation system according to the sort of a non-standard video signal. CONSTITUTION:A YC separation circuit 2 having the plural YC separation parts 21-23 separating a video signal to an luminance signal and a chrome signal according to the different YC separation system is provided. Then a video signal discrimination circuit 9 discriminates the sort of the coming video signal and gives the discrimination result to a YC separation part switching circuit 12. The switching circuit 12 selects the most proper YC separation part among the plural YC separation part 21-23 based on that discrimination result. Thus the presence or absence of the correlation of the coming video signal or the most proper YC separation part complying with an object having the correlation can be selected and the image can be improved more.
