1. A multi-view image coding method in which an input image of an object which is photographed by a first camera is divided into a plurality of coding target areas and, using an already-coded image of the same object which is photographed by a second camera which is located in a different position from the first camera, predictive coding is performed for each of the coding target areas, the multi-view image coding method comprising: a sample area setting step in which an area that is adjacent to the coding target area and has already been decoded in the input image is set as a sample area; a prediction image creation step in which a prediction image is created from the already-coded image of the object photographed by the second camera for pixels belonging to the coding target area and the sample area; a correction parameter estimation step in which, based on the prediction image for the sample area and on a decoded image that has already been decoded for the sample area, correction parameters for correcting illumination and color mismatches are estimated; a prediction image correction step in which, using the correction parameters, the prediction image for the coding target area is corrected so as to create a first corrected prediction image; an image coding step in which, using the first corrected prediction image, image signals of the coding target area is coded so as to create coded data; and an image decoding step in which the coded data is decoded so as to create a decoded image for the coding target area.
