ABSTRACT:
Compressed image files are partially preprocessed to expedite color correction and delivery of color corrected images. Color correction may be accomplished by processing only the luminance channel, only the color channels, or a combination of the luminance and color channels. A method for adjusting characteristics of a compressed image file including compressed characteristics elements and compressed image elements, includes: in the compressed image file, separating the compressed characteristics elements and the compressed image elements; decompressing one or more of the compressed characteristics elements; and adjusting the decompressed characteristics elements.
