Abstract
PURPOSE:To realize low-afterimage, high-sensitivity, and high blooming resistance characteristics while reducing the size of a chip, by securely removing blooming charge, which overflows from a photodiode to a vertical transmission line, before real signal charge is read out. CONSTITUTION:Photoelectric converting elements, each consisting of vertical MOS switches 32 and 32' connected to photodiodes 31 and 31', are arranged in a matrix of (n) rows by (m) columns, and respective elements are connected to an MOS type vertical shift register 34 through a two-line interlacing circuit 34' while an equivalent after image is removed. Further, the elements are connected to an MOS transistor TR36 for transfer through vertical transmission lines 35 and 35', to which a capacitance element 39 for storage, the 2nd transfer gate 310, etc., are conncted. Further, a buried channel charge coupled type horizontal shift register 312 which transmits optical signals horizontally is connected to a signal output part 313; and (n) columns of elements are grouped by two, and signal charge from the elements in respective groups are transferred simultaneously to corresponding lines 35 and 35' and read by a register 312.
