1. A high resolution color image reconstruction method which reconstructs a high resolution color image based on a single input image or a sequence of multiple input images captured by an image capturing device employing an image sensor and a color filter array, said high resolution color image reconstruction method characterized by reconstructing said high resolution color image having a predetermined resolution equal to or larger than a physical resolution of said image capturing device; and comprising the step of: conducting an image reconstruction process based on prior knowledge that relates to a model of an image capturing system or a subject including known or unknown displacement or deformation generated between said sequence of multiple input images, and then reconstructing said high resolution color image in which even a high spatial frequency component contained in said subject is truly reproduced and occurrence of false color is suppressed.
