ABSTRACT:
A solid state image sensor is constituted so as to transfer signal charges produced in response to optical irradiation to readout means (22) provided at the end in the direction of alignment of the transfer electrodes with charge transfer channels (30) located below a plurality of transfer electrode array (27) arranged on a semiconductor wafer (20) through an insulating film (32) and to output them from the readout means. The solid state image sensor is provided with means for controlling applied voltage comprising voltage sources (37, 38) of low and high voltages, multi-phase clock source (36) and switch means (34). The applied voltage control means, at a time period of optical irradiation, is operative to apply a voltage to form a deep potential well in transfer channels located below either odd number of transfer electrodes or even number thereof, and form a potential barrier in the transfer channels located below the other electrodes, thereby to store signal charges in the potential well. Further, this applied voltage control means, at a time period of signal readout in a light-interrupted condition, is operative to apply charge transfer multi-phase clocks from transfer electrodes closest to signal readout means sequentially towards those located apart therefrom.
