An image pick-up device includes a pixel portion having the matrix arrangement of pixels for converting a subject image to an electric signal, and a scanning unit having a plurality of sub-scanning circuits for outputting a video signal, including a first scanning circuit for selecting a pixel position in a first direction of the matrix in the pixel portion and a second scanning circuit for selecting a pixel position in a second direction intersecting at the first direction. At least one of the first scanning circuit and the second scanning circuit shares the respective signal lines. Further, the image pick-up device includes a scanning control circuit for controlling the first scanning circuit and the second scanning circuit. The structures of pixel areas are uniform, the structures of wirings are uniform, and the structures of vertical and horizontal driving systems and an output system are uniform. Thus, pixel signals of the pixels are outputted from two output systems without property difference and the image quality can be improved in the multi-channel output system.
