PROBLEM TO BE SOLVED: To generate a higher-definition image signal with simple processing and at a high speed. SOLUTION: A reference pair normalizer 76 normalizes an SD image signal to be supplied from an SD image extractor 75 on the basis of a dynamic range of a prediction tap supplied from a dynamic range operator 71, the dynamic range of a reference pair supplied from a dynamic range operator 73 and a minimum value of a reference pair supplied from a minimum value operator 74. A mean value operator 77 operates a mean value of the SD image signal normalized by the normalizer 76. A composer 78 generates an HD image signal by adding the mean value supplied from the operator 77 to a minimum value of the prediction tap supplied from a minimum value operator 72. This invention is applicable to an image processor. COPYRIGHT: (C)2005,JPO&NCIPI
