INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND STORAGE MEDIUM FOR ESTIMATING MOVEMENT AMOUNT OF MOVING OBJECT

An information processing apparatus, for estimating a movement amount of a moving object to which the information processing apparatus is attached, captures an image taken of an exterior view seen from the moving object. The apparatus estimates the movement amount of the moving object based on a first taken image taken at a first time and a second taken image taken at a second time earlier than the first time. The apparatus estimates the movement amount of the moving object based on a difference between image information on a predetermined region of each manipulated image obtained by manipulating the second taken image based on mutually different predicted movement amounts and image information on a predetermined region cut out from the first taken image.
