ABSTRACT:
A method of evaluating the quality of an image includes a step of determining at least a parameter concerning a zone or a parameter concerning a distribution pattern of sampling points within the zone. This step is performed based on the image. For each zone, Fourier analysis is performed using the optical characteristic values of the respective sampling points within the zone, and the image quality of each zone is obtained. The quality of the image is then determined based on the image quality of each zone within the image. A suitable zone and distribution pattern of sampling points are employed in evaluating the quality of an image.
