ABSTRACT:
The color video camera has a processing circuit which converts electrical signals obtained from an imager into a luminance signal and color-difference signals. The color video camera further includes a memory which stores a table of values designating color saturation levels and corresponding to a specific hue of a background color. The memory outputs a color saturation level based on the color difference signals obtained by imaging an object on a background of the specific hue. This color saturation level is compared with the luminance signal, and based on the comparison results the luminance signal and color difference signals are separated into components corresponding to the background area and components corresponding to the object area.
