Abstract
This invention relates to the reconstruction of a full colour image from image mosaic data in particular where the image mosaic data is unequally weighted between different colours. The image mosaic is composed of a plurality of image pixels. Each image pixel has one of at least three colour values and has a luminance value representing the intensity of the colour value for that pixel in the image mosaic. The pixels of each colour value are interleaved across the image mosaic with pixels of different colour values to form the image mosaic. For each colour value, both a low spatial frequency monochrome image and a high spatial frequency luminance image are generated, the high spatial frequency luminance image extending only across pixels locations of the image mosaic for that colour value. Each of the high spatial frequency luminance images is then combined with a corresponding low spatial frequency monochrome image to form the full colour image.
