Abstract

A pixel portion of an image pick-up device having a pixel portion of pixels arranged in matrix converting a subject image to an electric signal, and a scanning unit of sub-scanning circuits outputting a video signal, a first scanning circuit selecting a pixel position in a first matrix direction and a second scanning circuit selecting a pixel position in a second direction intersecting the first direction. One of the first and second scanning circuits shares the signal lines. The image pick-up device includes a scanning control circuit controlling the first and second scanning circuits. The pixel area structures of the pickup device are uniform, the wirings are uniform, and the vertical and horizontal driving systems and an output system are uniform. Thus, pixel signals outputted from two output systems have no property differences and image quality is improved.
