Abstract
An image recognition method is conducted by extracting characteristic points of the pattern of an image formed by video signals from an image pickup device, within the whole or a limited area of a frame of a display, and measuring the distribution of the characteristic points of the image pattern. With this method, images can be recognized with minimal image processing time and with reduced influence of noises.
