20100195723 | MOVING IMAGE ENCODER AND MOVING IMAGE DECODER - The encoding efficiency when a plurality of reference blocks are used to generate prediction blocks for encoding is improved. A moving image encoder performs inter-picture predictive encoding to encode a difference value from a block to be encoded by generating a prediction image of the block to be encoded by using a plurality of reference images extracted from an encoded frame. The moving image encoder comprises a prediction method candidate generating portion | 08-05-2010 |

20110255797 | IMAGE DECODING APPARATUS AND IMAGE CODING APPARATUS - When a filtering process on decoded image data is performed using filter parameters, gradient values near the pixel to be the target of the filtering process are calculated. In accordance with the calculated gradient, a single filter parameter is selected from a set of filter parameters. Based on the selected filter parameter, weight coefficients for the filtering process are calculated. Then, using the pixel value to be the processing target, the surrounding pixel values and the calculated weight coefficients, the pixel value after correction of the processing target pixel is calculated. With this process, it is possible to provide an image coding apparatus that can efficiently code an image properly and an image decoding apparatus that can decode an image, by performing a filtering process in accordance with the image characteristics. | 10-20-2011 |
