<p>PROBLEM TO BE SOLVED: To enable real time reproduction of an optional viewpoint image at reasonable cost by calculating a position of a referred area of a viewpoint image, generating a predictive signal at the position by using stored model information and decoding data of a part corresponding to the position of the referred area among stored pieces of predictive error data. SOLUTION: A position of a referred pixel for each point of a reproduced image is calculated (S1407). Namely, the position to be the one of the referred area in each viewpoint image to be referred to reproduce the viewpoint image to view the specified eye direction from the specified viewpoint position specified by the specified viewpoint position is specified. A tentative generation of the predictive signal is performed by performing tentative projection from a model to the position of the reproduced image (S1408). The predictive signal is generated at the position of the referred area (S1409). A predictive error block corresponding to the position of the referred area is read (S1410) and decoded (S1411). An image in the referred area is reproduced by adding the predictive signal and the predictive error together (S1412).</p> |
