A rendering processing unit within a graphic processing unit performs antialiasing (AA, removal of jaggies, stair effects etc.) on first colour data (e.g. luma) and second, different, colour data (e.g. chroma) using different operations, for example using different numbers of sampling data. The graphic processing unit includes a geometry processing unit and a rendering processing unit. The geometry processing unit is configured to receive vertexes and to generate at least one primitive using the vertexes. The rendering processing unit is configured to convert the generated at least one primitive into fragments, to perform fragment shading on the converted fragments, and to perform the anti-aliasing on the fragments on which the fragment shading has been performed. Also disclosed is performing fragment shading on first and second, different, colour data using different operations. This is performed in a graphics processing unit comprising a primitive assembly unit which receives vertexes and generates primitives, a tiling unit dividing the image into tiles and which generates texture patch information, and a rendering processing unit which performs the fragment shading. |
