A local region image tracking apparatus continuously tracks an arbitrary local region within a search image that is described by search image data by comparing the search image data to be subjected to a tracking process out of input image data picked up by image pickup means with reference image data related to the arbitrary local region. The local region image tracking apparatus includes an image data bus transferring the input image data from the image pickup means, and a plurality of correlation tracking processors coupled in parallel to the image data bus and respectively capable of independently carrying out the tracking process with respect to at least one search image, where the tracking process with respect to one or a plurality of search images is distributively carried out by the correlation tracking processors.
