A raw image consists of a plurality of pixels in a plurality of color
planes giving a color image. The raw image is split into at least a low
frequency image and a high frequency image. At least the low frequency
image is color corrected to produce a color corrected low frequency
image. The color corrected low frequency image is combined with at least
the high frequency image to give a final image which is of comparable
resolution to the raw image but is color corrected.
