ABSTRACT:
An image data processing method and apparatus for performing image correction processes for a restored image data file obtained from a JPEG-compressed image data file which may prevent block distortions and provide a high quality image.A JPEG-compressed data file is read from the storage medium by the reading section, which is restored at the restoring section. The restored data is then split into a low-frequency component and a high-frequency component at the splitting section. The low-frequency component is subjected to the white balance, density, and gradation adjustments at the first image correction processing section and combined with the high-frequency component at the combining section to obtain a combined image data. The combined image data is then subjected to the sharpness adjustment at the sharpness adjusting section, which is outputted from the output section to a printer and reproduced as a printed image.
