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 sub-pixels (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.
