Patent ID: 7657111

Claim:
An image processing apparatus for obtaining processed compressed moving image data by carrying out image enhancement processing on compressed moving image data, the image processing apparatus comprising: division means for dividing the compressed moving image data into a target part to be corrected and a non-target part not to be corrected; decoding means for obtaining decoded data by decoding the target part; correction means for obtaining corrected decoded data by carrying out the image enhancement processing on the decoded data; encoding means for encoding the corrected decoded data; combination means for obtaining the processed compressed moving image data by combining the target part that has been encoded with the non-target part; block division means for dividing the non-target part into intra blocks and inter blocks, the decoding means further obtaining decoded intra blocks by decoding the intra blocks, the correction means further obtaining corrected decoded intra blocks by carrying out the image enhancement processing on the decoded intra blocks, the encoding means further obtaining corrected intra blocks by encoding the corrected decoded intra blocks, and the combination means obtaining the processed compressed moving image data by combining the corrected decoded data and the corrected intra blocks with the inter blocks, and wherein the image enhancement processing comprises at least one of gradation correction, white balance correction, density correction, and sharpness processing.
