<p><P>PROBLEM TO BE SOLVED: To execute in-frame predictive encoding reduced in calculation resources required for prediction mode selection while achieving high throughput processing performance. <P>SOLUTION: This image encoding device predictively encodes image block data by any of a plurality of in-screen prediction modes by inputting the image block data and reference image data, and calculates a prediction value calculatable by similar calculation expressions and corresponding to a plurality of prediction modes. A combination of the prediction modes is previously determined and designated to a prediction value calculation part, and a prediction residual error is calculated from the image block data and the prediction value. The prediction mode is determined by using at least one of a prediction mode determination part, the prediction residual errors for the respective prediction modes, the image block data and the reference image data. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
