CSD type solid-state imaging device with means for draining excess charges

摘要

A CSD type solid-state imaging device having horizontal transfer means for transferring charges stored at the storage electrodes in the horizontal direction and gates for selecting elements having excess charges and drains for draining the excess charges, both provided at the vertical transfer means at the neighbourhood of the storage electrode. The charges of a plurality of light-electricity conversion elements provided spaced apart from each other by a distance of more than two picture elements in the vertical direction are read out to the vertical transfer means within a same horizontal blanking period and signal charges corresponding to at least more than one picture element are drained to the drain through the gate while transferring the charges in the vertical direction.
