Abstract
The system generates a digital pixel image in a framestore memory (20) by expanding run-length encoded data stored in a command memory (22). Each pixel has a variable characteristic such as its colour, or its depth in a 3-D image. The value of the characteristic for each written pixel is determined from the run-length encoded characteristic. The value of the characteristic for each pixel in the run is determined from a reference parameter which determines the initial value of the characteristic, and a difference parameter which represents the change in the value along the length of the run. The coordinates of the pixel runs may be determined from the coordinates of a preceding run. The initial location and run length for each run are determined relative to the preceding run by delta parameters associated with the current run. The system generates linear colour blends and automatically depth-clips images being written into the framestore (20).
