Abstract
In an image processing unit for performing an arithmetic operation between a reference image and a search image, a product-sum operation section comprises systoric array, a normalization and accumulation processing section and a correlation value memory control section. The product-sum operation section is used on a common basis for an operation for the addition of a square of a pixel value of a search image over a plurality of pixels and an operation for the addition of a multiplication of pixel values of pixels associated with the search image and the reference image over a plurality of pixels. An operation for a norm of the reference image is performed on a path (a reference image norm computing section) which is different from that of the product-sum operation section.
