An image processing apparatus and method, and a program-recorded recording medium perform detecting features of image information for classes which is input for learning, calculating the degrees of belongingness of the detected features to the classes, weighting pieces of the input image information based on the degrees of belongingness, and calculating prediction coefficients for the classes based on the weighted pieces of the image information. The apparatus and method, and program-recorded recording medium also perform detecting features of input image information for classes, calculating the degrees of belongingness of the detected features to the classes, weighting pieces of the input image information based on the degrees of belongingness, providing prediction coefficients for the classes, calculating pieces of predictive image information for the classes based on the weighted pieces of the image information and the provided coefficients for the classes, and adding the pieces of predictive image information for the classes.
