When receiving input scan lines from a conventional scanner, a system of the present invention simultaneously provides a sequence of pixels for display and a second sequence of pixels for storage, for example on a hard disk. A pixel for display has an intensity resolution greater than a pixel of the input scan line. The intensities of scan line pixels in a 16 by 16 matrix are accumulated for incrementally revising the intensity of the pixel to display. An incremental intensity is identified by a table indexing technique. The second sequence is the result of performing a data compression method on two sets of transitions. Each set is derived from an input scan line by noting the run length between changes in intensity. Intensities in one embodiment have single bit resolution. A subset of transitions is identified by a table indexing technique. Disk writes are delayed until a buffer has exceeded a limit value.

[ What is claimed is:] [1.] A data storage medium having recorded indicia comprising instructions for a processor to perform a method for processing pixels for displaying and storing, each pixel having a position within a sequence and having an intensity, the intensity having a resolution, the method comprising:receiving a first sequence of pixels;revising a second sequence of pixels to be provided for displaying, the intensity of a pixel of the second sequence being revised in response to respective intensities of a plurality of pixels of the first sequence, wherein revising comprises a first instruction that accounts for multiple pixels of the plurality;providing a third sequence, each member of the third sequence identifying a respective position of a pixel in the first sequence and an adjacent pixel of different respective intensities, wherein providing comprises a second instruction that accounts for multiple pixels of the first sequence; andproviding a fourth sequence for storing, the fourth sequence resulting from performing a data compression method on the third sequence.
