Abstract
An object position coordinate computing and selection method and apparatus detects one or more areas satisfying a predetermined criterion in a captured digital image and compares an object-position coordinate point to associate with such areas. When a plurality of such areas have been detected and associated object-position coordinate points have been computed, the coordinate computing method and apparatus sets a reference value based on at least one or both of a direction of a line connecting the first two object-position coordinate points recognized in the image and a length of the line connecting the two object-position coordinate points. The coordinate computing method and apparatus then selects a single pair combination of object-position coordinate points out of the plurality of possible pair combinations of object-position coordinate points that is closest to the set reference value for use as selected object position coordinate points.
