The Invention
The invention is directed to a dithering technique for
displaying an image that appears to have better resolution on a
device that does not have enough color or intensity resolution to
display an image of that quality. According to the appellant,
the invention represents an improvement over prior art dithering
techniques by not requiring a first comparing step which compares
certain lower bits in the intensity information with pre-stored
values before deciding whether the remaining upper bits of the
intensity information are to be incremented.
Claims 1 and 3-12 are apparatus claims, and claims 2 and 13-
2
