Abstract
A solid-state imaging device includes a plurality of light receiving elements, transfer gates for controlling reading-out of signal charges generated by the light receiving elements, a charge coupled device for transferring the signal charges from the light receiving elements through the transfer gates, a charge input electrode, and first and second electrodes for controlling the quantity of charges input from the charge input source. The first electrode contacts the charge input source. The second electrode contacts the first electrode and is connected to a light receiving element via a transfer gate or another charge coupled device. In this structure, the second electrode controls the quantity of input charges in response to a dc voltage in a charge input mode for testing the images and serves as a first stage transfer electrode in response to a clock pulse in a imaging mode for forming an image. Thus, the pitch of the light receiving elements is constant even at the charge input electrode.
