Abstract
A system and process for scaling a binary image. The present invention includes a prestored set of scaler, or look-up, tables that each map all combinations of a specified number of input bits into a specified number of output bits. A sequencer is generated to direct the column scaling of the image. The sequencer includes a bit-string wherein each bit specifies the selection by a scaler function of a scaler table allowing interpolation of a preselected scale factor. The sequencer also includes information that allows the efficient processing of image data by aligning processed data on memory boundaries of a computer. The present invention may be used by an image memory management system or an image processing application to rescale images at high speeds on a conventional computer.
