ABSTRACT:
An image processor detects a specified pattern defined by arrangement of three or more elements. Positions of a plurality of element candidates are detected based on input image data, and n pairs (n≧2) of element candidates are selected in the plurality of elements. Then, n arrangement criterions are determined based on the positions of the selected n pairs, and one arrangement criterion is determined based on the n arrangement criterions. By using the one arrangement criterion, positions of all the elements are calculated in the specified pattern. The specified pattern is detected based on the calculated positions of the arrangement.
