ABSTRACT:
A solid state image sensor of charge sweep architecture comprises photodetectors in two-dimension, vertical charge transfer elements and a horizontal charge transfer element. A driver circuit for the vertical charge transfer elements mounted in the solid state image sensor comprises a circuit for setting initial states of shift registers and a circulation loop line connecting an output of the shift register at the last stage to an input of the shift register at a first stage. Thus, a lower consumption power and high efficiency charge transfer are provided in the solid state image sensor.
