Charge transfer image pickup device

Abstract

Abstract PURPOSE:To increase the number of picture elements toward the horizontal direction with the same chip area, by turning a unit cell against a horizontal shift register by an angle theta and decreasing the pattern size toward the vertical direction. CONSTITUTION:A unit cell consists, e.g., of a photoelectric conversion section P11, a transfer control region T11, a electric charge passing region B11 and a charge storage region S11 and is arranged being turned by an angle theta1 against a horizontal shift register. Signal charges stored in response to incident light amount via photoelectric conversion sections P11-P33 are transferred to charge storage regions S11-S33 of corresponding vertical shift registers respectively via transfer control regions T11-T33, and then the vertical shift register is sequentially transferred and the signal charges are read out at every horizontal scanning through a shift register 9. Thus, the objective pickup output can be obtained from an output section 10 of the horizontal shift register 9.
