摘要：
This specification discloses an improvement in an image pickup device incorporating therein an optical system which reduces the delay of the photoelectric signal by separately adding bias light to the light from an object. The improvement is characterized in that the bias light is introduced through that portion of the face plate which makes no contribution to image pickup.
