摘要： A degraded-image restoration method includes inputting a degraded image degraded by a predetermined degradation process; reading from a storage unit a filter coefficient in a filtering process of restoring the degraded image, in which an iteration formula for minimizing a square error between the degraded image and an image obtained by degrading a restored image by the degradation process is expanded corresponding to a predetermined number of iterations; and performing the filtering process using the filter coefficient with respect to the degraded image to obtain a restored image of the degraded image. Accordingly, a throughput in an apparatus that restores the degraded image can be reduced, thereby obtaining a preferable restored image.

The image data acquisition unit acquires pixel data of first image data of an erect image obtained by a line sensor comprising a plurality of light receiving elements. The erect image is formed by a plurality of gradient index lenses of a lens array. The filter setting unit sets sharpening filter coefficients of a filter to be applied to the pixel data of the first image data corresponding to the respective light receiving elements, according to remainder values obtained respectively by dividing positions of the light receiving elements on the line sensor by an interval of a lens arrangement of the lens array. The filtering processor generates second image data sharpened by applying the obtained sharpening filter coefficients to the respective pixel data of the first image data.
