Abstract
In an image encoding method in which a pixel of interest is predicted with reference to a plurality of pixels near the pixel of interest to be encoded, and encoding is performed on the basis of coincidence/noncoincidence between the predicted pixel and the pixel of interest, a parameter for predicting a pixel is changed on the basis of a rate of coincidence/noncoincidence of the predicted pixel and the pixel of interest.
