Claim One:
1. An image processing device for converting an input image into an output image whose blur is reduced more, said image processing device comprising: first image extracting means for extracting a plurality of pixels composed of a pixel of said input image which pixel corresponds to a pixel of interest as a pixel to which to direct attention within said output image and predetermined pixels surrounding the pixel of said input image; first feature quantity calculating means for calculating a first feature quantity from said plurality of pixels extracted by said first image extracting means; processing coefficient generating means for obtaining a second processing coefficient by operation on said first feature quantity and a first processing coefficient, said second processing coefficient being generated by operation on said first feature quantity and said first processing coefficient learned in advance from a normal equation based on a relational equation for generating an unblurred teacher image by operation on the second processing coefficient and blurred images to which blurs of a plurality of kinds of amounts of blurring are added as student images; second pixel extracting means for extracting a plurality of pixels composed of the pixel corresponding to said pixel of interest and predetermined pixels surrounding the pixel corresponding to said pixel of interest from said input image; and predicting means for generating a pixel value of said pixel of interest by operation on said plurality of pixels extracted by said second pixel extracting means and said second processing coefficient.
