PHOTOSENSITIVE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a full color photosensitive device in which the integrating time of each photogate can be controlled easily for each pixel. SOLUTION: The photosensitive device has first and second photogates each generating charges in response to received light. The charges flow into a phototransfer gate depending on the potential difference between the photogate and the phototransfer gate coupled therewith. A common node 10 coupled with first and second phototransfer gates is coupled with an output line. A reset gate is arranged at a reset node 12 on the output line and applies a specified reset potential to the reset node 12 as required. A clearing gate arranged on the output line between the common node 10 and the reset node 12 can apply a specified potential onto the common node 10 thus removing charges entirely from at least one photogate.
