METHOD OF AND APPARATUS FOR PROCESSING FRAMES IN A DATA PROCESSING SYSTEM |
| 摘要 |
An apparatus for providing a foreground frame to be composited with a background frame in a chroma-keying arrangement, each of the foreground frame and the background frame comprising one or more regions that together form the respective frame. A detection module determines whether each frame region has a predetermined colour value and generates and stores chroma keying information based on the determination. Control circuitry then controls image processing to be performed on the region according to the stored chroma keying information. |

1. A method of providing a foreground frame to be composited with a background frame, the foreground frame comprising one or more regions, the method comprising, for at least one region of the foreground frame:
determining if the region has a predetermined colour value; generating and storing chroma keying information based on the determination; and controlling image processing to be performed on the region according to the stored chroma keying information. |
