Abstract

PURPOSE:To recognize an outline location of an object in an image with simple hardware constitution by providing a counter splitting the image into plural regions and counting the number of image elements changed in each region corresponding to each region. CONSTITUTION:An absolute value difference between an input image from an image pickup means 1 and a reference image from a reference image memory 2 is obtained by a difference means 3 and the difference is binarized by a binarizing means 4. An image element counter 6 counts the number of image elements bringing the output of the binarizing means 4 to a specific value by using a counter designated by a counter selector 7. The counter selector 7 decodes the value read from a window image memory 5 to designate the counter. A position decision means 8 reads out the value of each counter in the image element counter 6 and decides the location of a tracing object depending on the count.
