Colour correction of images
A raw image consists of a plurality of pixels in a plurality of colour planes giving a colour image. The raw image is split into at least a low frequency image and a high frequency image. The low frequency image is colour corrected to produce a colour corrected low frequency image. The high frequenc...

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