SIGNAL PROCESSING APPARATUS AND METHOD, RECORDING MEDIUM, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a technology capable of generating an image signal with higher quality.

SOLUTION: An HD prediction section 11 generates an HD image signal with a density of a multiple of four from a received SD image signal. A prediction value evaluation section 12 evaluates an HD prediction value generated by the HD prediction section 11, and calculates a correction amount E corresponding to the evaluation. A HD prediction value correction section 13 subtracts the correction amount E generated by the prediction value evaluation section 12 from the HD prediction value generated by the HD prediction section 11 to correct the HD prediction value. The terminal or the like is applicable to television receivers.
