ABSTRACT:
A method for separating luminance (Y) and chrominance (C) of composite signals is presented. The method includes the process of determining whether a target position of a target field has motion and whether the image of the target position meets a predetermined condition. If the target position of the target field has motion and the image of the target position meets the predetermined condition, an inter-field Y/C separation for video signals corresponding to the target position of the target field is performed.
