Abstract
An image is coded by counting runs of non-background picture elements, and counting consecutive scanning lines having only background picture elements. Consecutive scanning lines of this type are coded as a single command and value, giving the number of scanning lines. Consecutive scanning lines having identical numbers of runs of non-background picture elements are coded as another single command and value, giving the run count, followed by run information describing each run. Sparse images, consisting mostly of background area, can be coded efficiently in this way.
