IMAGE MOMENT SENSOR, IMAGE MOMENT MEASUREMENT DEVICE, COMPUTATION METHOD FOR IMAGE MOMENT SENSOR, AND IMAGE MOMENT MEASUREMENT METHOD

摘要

PROBLEM TO BE SOLVED: To simplify the configuration of pixel circuits and increase the speed of moment computation.;SOLUTION: A signal processing part 3 supplies a clock signal ϕ[0] and supplies column selection signals x^pi[0] to x^pi[N-1] to an image processing part 1. Delay circuits (delay) 11_1 to 11_(N-2) delay the clock signal ϕ[0] sequentially. FIFOs 12_1 to 12_(N-1) supply the column selection signals x^pi[0] to x^pi[N-1] supplied from the signal processing part 3 to processing elements 13_xy. Processing elements that are supplied with a column selection signal of a value "1" compute partial sums of an input image in a row direction to supply the computation result to a column addition part 2. The signal processing part 3 supplies a row selection signal yj to the column addition part 2, and the column addition part 2 performs an addition according to the supplied row selection signal yj to output a signal SOUT.;COPYRIGHT: (C)2007,JPO&INPIT
