WIPO Patent Application WO/2008/126843

Kind Code:

A1

Abstract:

It is possible to provide an image prediction/encoding device, an image prediction/encoding method, an image prediction/encoding program, an image prediction/decoding device, an image prediction/decoding method, and an image prediction/decoding program which can select a plurality of candidate prediction signals without increasing an information amount. A weighting device (234) and an adder (235) perform a process (averaging, for example) of pixel signals extracted by a prediction adjacent region acquisition device (232) by using a predetermined synthesis method so as to generate a comparative signal for an adjacent pixel signal for each of combinations. A comparison/selection device (236) selects a combination having a high correlation between a comparison signal generated by the weighting device (234) and an adjacent pixel signal acquired by an object adjacent region acquisition unit (233). A prediction region acquisition unit (204), a weighting unit (205), and an adder (206) generate a candidate prediction signal and process it by using the predetermined synthesis method so as to generate a prediction signal.
