Patent ID: 8466994

Claim:
An image pickup system comprising: a polynomial arithmetic operation unit that carries out an arithmetic operation of a polynomial of a second or higher order; an arithmetic operation controller that generates a variable of the polynomial and controls the arithmetic operation in the polynomial arithmetic operation unit; a pulse generator that generates a pulse based on a result of the arithmetic operation in the polynomial arithmetic operation unit; a counter that counts a clock pulse, wherein the pulse generator carries out a comparison based on the result of the arithmetic operation in the polynomial arithmetic operation unit and a count value of the counter to generate a pulse corresponding to a result of the comparison; and a mechanical shutter device having a light shielding blade for shielding a pixel region of a solid-state image pickup device, wherein the pulse generator generates a pulse for stipulating starting of a signal accumulating period of the solid-state image pickup device and the mechanical shutter determines a completion of the signal accumulating period.
