摘要：
An image processor having a circuit for holding data on features of registered specific images, a circuit for determining the degree of similarity between features of an input image and the held features of each of the specific images, and a circuit for updating the held content of the holding circuit from the outside through a line. The image processor also has a judgment circuit for determining the degree of similarity between an input image and each of the specific images according to tint distributions of these images, and a circuit for registering data on the tint distribution of each specific image.
