Abstract
A method and apparatus for processing a scan line of image data, wherein image data from portions of the scan line is processed simultaneously along plural channels, each channel processing a portion of the image data, and provided with context information from an adjacent portion of the scan line. Context pixels are added at the trail edge of a first scan line portion, derived from the lead edge of a second scan line portion. In certain image processing requiring preceding and succeeding pixel context information, subsequent to processing, on correctly processing pixels are transferred for subsequent processing, and pixels at the trail edge of a first scan line portion, and the lead edge of a second scan line portion are not transferred, leaving complementary scan line portions.
