| Outline of Final Research Achievements |
We studied a new picture encoding method to realize performance superior to the high efficiency encoding method of the existing international standard of video signal. We suggested new approach called "non-causal encoding" that performing batch processing by using to the information of the image which was not yet encoded, whereas the existing standard was a method called "causal encoding" with only the information of the image which was already encoded.
Depending on the coding mode and the target image, but the image quality improvement of about 6dB was achieved. Also, cited accomplishments related to Image Retargeting algorithm (Multiple display technology for multiple images). As a result, we achieved the following three goals, ①parallel architecture of encoder configuration, ② improvement of coding efficiency, ③ encoder scope expansion.
