Image correlator, an image processing apparatus using the same, and a signal adder used in the image correlator

摘要

In order to reduce the size of an apparatus capable of obtaining a result of correlation between images at a high speed, a multiplex selector for shifting addresses of a plurality of memories, a detector for detecting an amount stored in a memory element of one of the plurality of memories and an amount stored in a memory element obtained by shifting an address of the one of the plurality of memories, and a determination unit for obtaining correlation between outputs of the detector for each amount of shift.
