Abstract:
A digital signal processing apparatus for processing an input digital image signal and generating an output digital image signal, comprising:generating means for generating the output digital image signal, said means being supplied with said input digital image signal and having means for clustering a plurality of pixel data of said input digital image signal adjacent to a subject pixel data to produce a class, a memory for storing predictive operation parameter data for respective classes at addresses corresponding to said respective classes determined by said clustering means, means for selecting a plurality of pixel data from said input digital image signal corresponding to a pixel data of said output digital image signal, and predictive operating means for operating said predictive operation parameter data from said memory and said plurality of pixel data from said selecting means; and control means for controlling said generating means such that said generating means selects one of a plurality of kinds of predictive operation and generates the output digital image signal corresponding to the selected kind of predictive operation.
