Patent ID: 7512267

Claim:
A learning apparatus comprising: first pixel-extracting means for extracting a plurality of pixels located near each pixel of interest of a student-image signal which has color components at positions of pixels, respectively; class-determining means for determining a class from the pixels extracted by the first pixel-extracting means; second pixel-extracting means for extracting a plurality of pixels located near positions corresponding to the position of the pixel of interest of the student-image signal, from a teacher-image signal which corresponds to the student-image signal and which have a plurality of color components for each pixel; and prediction-coefficient generating means for generating a set of prediction coefficients for each class, for use in generating an image signal corresponding to the teacher-image signal from an image signal corresponding to the student-image signal, in accordance with values of the pixels extracted by the first pixel-extracting means and second pixel-extracting means.
