ABSTRACT:
An image processing system which generates a luminance signal and a color difference signal based on chrominance signals read from an image pick-up device. The image pick-up device includes a green striped and red/blue perfectly checkered filter arrangememt, or a similar filter having an arrangement of complementary colors. In the image processing system, a luminance signal and a color difference signal corresponding to an arbitrary picture element are formed by performing arithmetic operations in which a corresponding signal generated from the arbitrary picture element, and a plurality of signals generated from adjacent picture elements with respect to the arbitrary element, are added together after the generated signals are multiplied with respective suitable load factors. The image processing system provides improved resolution and helps prevent the occurrence of spurious colors on a processed image.
