IMAGE DEFINITION ENHANCEMENT METHOD, IMAGE DEFINITION ENHANCEMENT DEVICE AND IMAGE RECOGNITION DEVICE

摘要

PROBLEM TO BE SOLVED: To generate a reconstructed image from an observed image picked up by a low resolution CCD camera from a continuous image, in approximation to a target image obtained when a high resolution CCD camera picks up the continuous image.

SOLUTION: ALand AHare operators for relating a target image f to an observed image g and a continuous image fcrespectively. ALincludes optical characteristics, electrical characteristics and the like of a low resolution CCD camera. AHincludes optical characteristics, electrical characteristics and the like of a high resolution CCD camera. A reconstruction operator based on ALand AHalso includes the optical characteristics and electrical characteristics of the low resolution CCD camera and high resolution CCD camera. The reconstruction operator including the optical characteristics and electrical characteristics of the low resolution CCD camera and high resolution CCD camera can be caused to operate on the observed image picked up by the low resolution CCD camera to generate a reconstructed image approximate to the target image.
