Abstract (en)
[origin: WO2007122202A1] The domain of the invention is display systems comprising graphic generation systems. The preferred application domain is the inset of synthetic symbologies output from graphic generation systems on one or more video images. The invention is particularly applicable to display systems on board aircraft. The invention is particularly related to a method of coding pixels of a colour digital image, each coloured pixel being coded on three digital components each comprising the same number of bits, characterized in that at least one of the coded components comprises firstly colour information and secondly weighting information, said weighting information being designed for use by digital filtering or antialiasing type image processing algorithms.
