FIELD: physics, computer engineering.
SUBSTANCE: invention relates to digital imaging means. The system comprises a pixel pre-processing unit comprising logic for collecting automatic white balance statistics and automatic exposure setup statistics, statistics collection logic comprising an input, colour space transformation logic and a set of pixel filters. The system also comprises control logic configured to determine a set of point white balance gain coefficients to apply to multi-colour raw frame pixels based on accumulated colour sum values.
EFFECT: high quality of the resultant image by eliminating artefacts in a full-colour image.
