A technique for encoding pixel colour values for a full or partial digital video image frame has each different colour within the image being assigned a colour value. The most common one of the colours (0) within the frame or frame segment is identified, and runs of at least three successive pixels of that predominant colour are encoded as a first code (00) indicating a run and a second code indicating the run length (LL). Runs of successive pixels having a colour (1, 2, 3) other than the predominant colour (0) are encoded as successive iterations of a code containing only the respective colour value when the run length is less than or equal to a threshold value and as a first code indicating a run (00), a second code indicating a run length (LL), and a third code (CC) identifying the colour value when the threshold value is exceeded. |
