Abstract:
1. An image processing apparatus for converting a first image into a second image having higher image quality than that of the first image, comprising: first means for extracting a plurality of pixel values, within the first image, corresponding to a position of a pixel of interest and peripheral positions of the position of the pixel of interest within the second image; means for obtaining estimate noise amounts for the plurality of pixel values extracted by the first means for extracting, respectively; means for generating second processing coefficients by arithmetically operating on first processing coefficients previously learned from a normal equation and the estimate noise amounts obtained by the means for obtaining for the plurality of pixel values, respectively, within the first image, the normal equation being obtained based on a relational expression for generating a teacher image, corresponding to the second image, having higher image quality than that of a student image, corresponding to the first image, in accordance with an arithmetic operation for the second processing coefficients obtained in accordance with estimate noise amounts of pixel values within the student image, first processing coefficients, and the student image; second means for extracting a plurality of pixel values, within the first image, corresponding to a position of a pixel of interest and peripheral positions of the position of the pixel of interest within the second image; and means for generating a pixel value of the pixel of interest within the second image in accordance with an arithmetic operation for the plurality of pixel values extracted by the second means for extracting, and the second processing coefficients.
