Abstract
A run-length encoder circuit for use in compacting data samples from a multicolor cartographic source chart includes hardware filtering which counts the number of incoming identical color samples and rejects them as noise unless they exceed a programmable count; the actual count value being dependent simultaneously on the number of incoming color samples and also the particular type of color, either a line color or an area color which was recognized as valid.
