The present invention relates to a correlation detecting device which has an analog shift register consisting of a pair of minor loops, a difference detection circuit to form signals for difference between corresponding bits thereof, and a major analog shift register to add differential outputs within a 1 minor-loop and to make 1 bit out of the same, and is so made that the maximum correlation is to be detected by bits having the minimum values out of the bits of the major analog shift register.
1. An image signal processing device used in an image correlation detecting device comprising: first and second analog shift registers for respectively retaining and shifting signals as an image of an object, said first and second analog shift registers forming respectively closed loops to shift signals in successive cycles, the signals in the bits in the first analog shift register and that in the second analog shift register being arranged to be offset relative to each other; comparison means for comparing said signals of the image for every corres...
