Appeal No. 94-2081
Application No. 07/809,984
Claim 1. A method of processing an image, comprising the
steps of:
a) digitizing the image to produce a map of the image,
said map containing pixels having a digital data resolution of
2 grey levels, wherein n is the number of bits per pixel;n
b) downsampling the map of the image digitized in step a)
to produce a dounsampled [sic, downsampled] map of the
digitized image; and
c) reducing the digital data resolution of the digitized
image by thresholding the downsampled map of the digitized
image to reduce the number of bits per pixel from n bits per
pixel to m bits per pixel, to thereby produce a reduced
digital data resolution, thresholded downsampled map of the
digitized image, where m is greater than one and is less than
n.
