Abstract
In an image sensor having a large scale array of semiconductor photodetectors, only the noise component is delivered from a first photodetector subsequent to the readout of a stored signal, in synchronism with the readout of a signal of a second photodetector, so that the noise component may be utilized for the cancellation of the noise component in the output from the second photodetector.
