Abstract:
A solid state image sensor system comprising:n (n is an integer which is 2 or more) pixel rows, each of which has pixels arranged in a row, each of said pixels being irradiated with light to carry out a photoelectric transfer to generate a signal charge; n analog shift registers, each of which is provided for each of said pixel rows to sequentially transfer a signal charge, which is generated from a corresponding one of said pixel rows; a charge detecting part, which is provided commonly for all of said analog shift registers, and to which signal charges are alternately given from a final stage of each of said analog shift registers, for storing and detecting said signal charges; and a reset drain for discharging said signal charges stored in said charge detecting part, wherein a final stage of each of said analog shift registers and a rest of each of said analog shift registers are configured to be driven independently, and when said signal charges are read out at a resolution of 1/n, signal charges generated in one of said n pixel rows are detected by said charge detecting part, and signal charges generated in other nâˆ’1 pixel rows of said n pixel rows are discharged to said reset drain, in accordance with a transfer clock applied on the final stage.
