ABSTRACT:
A charge-transfer image sensor comprises a photosensitive section for receiving a light signal to produce a charge packet corresponding to the intensity of the light signal, a readout shift register for reading out the charge packet for transfer, an output detecting section for storing the charge packet read out of the readout shift register and detecting it, an output conversion circuit for producing an output voltage signal corresponding to the amount of charge of the packet, and a storing shift register for holding charge packets transferred from the output detecting section.
