ABSTRACT:
A solid state imaging device includes an array of photosensitive elements for storing signal charges, a plurality of vertical shift registers for storing the signal charges transferred from the photosensitive elements, charge storage sections for storing one field of signal charges transferred from the respective vertical shift registers, a horizontal shift register for storing one line of signal charges transferred thereto successively at time intervals from the charge storage sections, a timing generator for producing clock pulses for driving the vertical shift registers to transfer the signal charges from the vertical shift registers to the charge storage sections and to sweep residual charges from the vertical shift registers, and a driver for amplifying the clock pulses fed thereto from the timing generator. The driver has a variable amplification factor. The amplification factor of the driver is controlled to provide a smaller amplitude for the clock pulses used to sweep the residual charges than for the clock pulses used to transfer the signal charges.
