Abstract
Color information lost in a computer graphics system as a result of encoding by dithering is recovered by passing the encoded data through a filter that has the same effective shape and size as the dither matrix used to encode the data. In a system that employs a dither matrix having 2.sup.N cells, up to N bits of color information, per color component, is recoverable.
