SYSTEMS AND METHODS FOR EFFICIENT HALFTONE SCREENING |
| 摘要 |
A graphics processing method receives a plurality of contiguous pixels, as a single input, including at least a first pixel span associated with a first content type and a second pixel span associated with a second content type. At least one dithering matrix is associated with each of the pixel spans based on the corresponding content type, so that the first and the second pixel spans are associated with different dithering matrices. The single input of the received plurality of pixels is then concurrently processed using an SIMD (Single Instruction Multiple Data) type processor by referring to different dithering matrices depending on the content type of the corresponding pixel spans. |

1. A graphics processing method comprising:
receiving a plurality of contiguous pixels, as a single input, comprising at least a first pixel span associated with a first content type and a second pixel span associated with a second content type; associating at least one dithering matrix with each of the pixel spans based on a corresponding content type, so that the first and the second pixel spans are associated with different dithering matrices; and concurrently processing the single input of the received plurality of pixels using an SIMD (Single Instruction Multiple Data) type processor by referring to different dithering matrices depending on the content type of the corresponding pixel spans. |
