In a dictionary image generating section, images of objects each belonging to any one of L categories are taken by a camera from predetermined M directions, a matching region of the object to be recognized is extracted from each of the object images, and dictionary images (N&equals;L&times;M, n&equals;1, 2, . . . , N) which are the representatives of combinations of direction and category are generated and stored together with the directions of the objects. When a test image is given, the degree of similarity r(n, X, Y) between an n-th dictionary image and the image region at the matching position (X, Y) in the test image is computed by a matching section. This matching process is repeated with the matching position (X, Y) and the number n of the dictionary image being varied, and the matching position (X,, Y,) where the degree of similarity r(n) becomes the highest is detected.

Object image detecting method and system

Image information units, related with one another in the order of their magnitudes defined for each of a plurality of properties of each image, are prestored in an image information storage and management device. All image information units adjoiningly related by their properties with a main image being displayed on a display are read out of the image information storage and management device, and contracted images of the read-out image information units are displayed as navigators on the display screen, together with the main image.
