ABSTRACT:
A photo-sensor device comprises a light receiving part composed of a plurality of photo-sensor elements for converting photosignals into electrical signals. A portion of the light receiving part is shielded by light shielding means so that in reading out the output from the device, there can be obtained also a signal of dark current information from the shielded photo-sensor elements.
