Solid-state image pick-up device with reference level clamping and image pick-up apparatus using the same

摘要

In order to stabilize the reference level of an output signal from a solid-state image pick-up device, the solid-state image pick-up device includes an output circuit 12 for obtaining a picture signal Y1(t) from information charges outputted from a horizontal shift register 11, an impedance conversion circuit 13 for reducing the output impedance of the picture signal Y1(t) and a clamp circuit 14 for fixing the reference level in the picture signal Y1(t), all of which are integrated on the same semiconductor substrate.
