Abstract

An image encoding method includes determining corresponding points on an encoding target image, which correspond to pixels on a reference image, based on distance from a camera of the reference image to an object, and positional relationship between cameras; computing a parallax vector from each pixel position to the corresponding point in pixel space; computing a target predictive vector having the same start as the parallax vector and components obtained by rounding off components of the parallax vector; computing a target reference vector having the same start as the parallax vector and the same size and direction as a differential vector between the target predictive vector and the parallax vector; and setting a predicted value of a pixel on the encoding target image, which is indicated by the target predictive vector, to a value of a pixel on the reference image, which is indicated by the target reference vector.
