Abstract
An apparatus for, and method of, increasing compensation sequence storage density in a projection visual display system and a projection visual display system incorporating the apparatus or the method. In one embodiment, the apparatus includes: (1) a memory containing a first compensation sequence portion that is common to a plurality of effective transmission factors and a plurality of second compensation sequence portions that are unique to a corresponding plurality of effective transmission factors and (2) a compensation sequence generator coupled to the memory and configured to construct a compensation sequence for use in the projection visual display system using the first compensation sequence portion and one of the plurality of second compensation sequence portions selected as a function of a particular effective transmission factor.
