A method for recognizing an object image comprises the steps of extracting a candidate for mineda predetermined object image from an overall image, and making a judgment as to whether the extracted candidate for the predetermined object image is or is not the predetermined object image. The candidate for the predetermined object image is extracted by causing the center point of a view window, which has a predetermined size, to travel to the position of the candidate for the predetermined object image, and determining an extraction area in accordance with the size and/or the shape of the candidate for the predetermined object image, the center point of the view window being taken as a reference during the determination of the extraction area. A learning method for a neural network comprises the steps of extracting a target object image, for which learning operations are to be carried out, from an image, feeding a signal, which represents the extracted target object image, into a neural network, and carrying out the learning operations of the neural network in accordance with the input target object image.

[ What is claimed is:] [1.] A method for recognizing an object image, which comprises the steps of:i) extracting a candidate for a predetermined object image from an overall image, andii) making a judgment as to whether the extracted candidate for the predetermined object image is or is not the predetermined object image,wherein said extracting step comprises:a) causing the center point of a view window, which has a predetermined size, physically to travel on said overall image to the position of said candidate for the predetermined object image, such that the portion of the overall image within the view window varies, said causing step comprising the steps of: composing a first travel vector relating to a detected contour line of said candidate; composing a second travel vector related to an object image exhibiting a movement different from background movement of the overall image; composing a third travel vector related to a region which approximately coincides in color with said candidate; and composing a composite travel vector from said first, second and third travel vectors, said composite travel vector being used to cause the center point of the view window to travel over the overall image to the position of said candidate; andb) determining an extraction area in accordance with predetermined characteristics of said candidate for the predetermined object image while using the center point of said view window as a reference.
