摘要: A method and apparatus for processing image information. An address designation or token is applied to each pixel or data byte in a scan line of image data describing its position in the scan line. By providing each data byte of image information with an address token defining its specific position in the scan line, the image information for data byte on the image is specifically located in the final image configuration, without requiring storage of the entire image information for manipulation. Operation on both data and address token is possible for image manipulation routines.

摘要: 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.
