Abstract
An image region of an image data memory is dissected into a plurality of search sections. Brightness change points in each of the search sections are counted based on image data of each search section. A candidate region having a likelihood of involving an information code is detected based on the count value of the brightness change points. And, the candidate region is identified as the existing area of the information code.
