The present invention relates to a solid-state image pickup device
comprising a sensor array and a plurality of transfer registers for
transferring signal charges from the sensors of the sensor array, wherein
an accumulation gate is provided between the sensor array and the
transfer registers for storing the signal charges from all the image
sensors at a same time and subsequently allocating the signal charges to
transfer registers. As a result, it is possible to provide a device
capable of producing a higher-quality signal output by eliminating sensor
to sensor variations in sensitivity and deviations in signal-charge
fetching between sensors.
