Abstract
In an image pick up apparatus having an image pick up device (1), an amplifier (2), a vertical contour compensation circuit (500), a gamma correction circuit (8), a horizontal contour compensation circuit (9), a color operation circuit (200), and an encoder (10), pixel compensation circuits (100, 100') are provided for reducing modulation components are caused by a color filter during saturation in an image pick up device (1). Horizontal low-pass circuits (7a, 7b) combined with clippers (24a, 24b) are provided in the vertical contour compensation circuit (500) to reduce a modulation components caused by such compensation in the pixel compensation circuits (100, 100').
