Abstract: An ordered dither method is applied to reduce the chromatic resolution of an image represented by channels R (red), G (green), B (blue) and A (brightness), whereby a first and a second dither matrix is provided, both comprising the same threshold values but arranged in a different spatial distribution. The first dither matrix is applied to the R, B, and A channels, and the second dither matrix is applied to the G channel.

Abstract: A system for rendering a primitive of an image to be displayed, for instance in a mobile 3D graphic pipeline, the primitive including a set of pixels. The system is configured for: - locating the pixels that fall within the area of the primitive, - generating, for each pixel located in the area, a set of associated sub-pixels, - borrowing a borrowed set of sub-pixels from neighboring pixels, - subjecting the set of associated sub-pixels and the borrowed set of pixels (A, B, C, D) to adaptive filtering to create an' adaptively filtered set of sub­pixels (AA, BB, CC, DD), and - subjecting at least the adaptively filtered set of sub-pixels (AA, BB, CC, DD) to further filtering to compute a final pixel adapted for display. Preferably, the set of associated sub-pixels fulfils at least one of the following requirements: the set includes two associated sub-pixels and - the set includes associated sub-pixels placed on triangle edges.
