Abstract
An image processing apparatus includes a full feature point detection section for detecting as a full feature point a point whose pixel value changes significantly along any line through the point, and a semi feature point detection section for detecting as a semi feature point a point whose pixel value hardly changes along one line through the point but changes significantly along other lines through the point.
