Appeal No. 95-2848
Application 07/796,971
from the examiner's rejection of claims 1-14, which constitute
all the claims in the application.
The claimed invention pertains to a method and apparatus
for converting an input image made up of a plurality of pixels
into an output image made up of a plurality of pixels. More
specifically, input pixels which correspond to an edge region are
converted to smooth output pixels by considering the intensity
values of pixels which surround the edge pixel.
Representative claim 1 is reproduced as follows:
1. A method of processing an input image having a
plurality of input pixels to generate an output image having a
plurality of output pixels, comprising the steps performed for
each input pixel, of:
a first forming step of forming a first value from
intensities of a first set of pixels around the input pixel;
determining whether the first value is a member of a
first set of values;
a first setting step of setting an output pixel
intensity, corresponding to the input pixel, in accordance with
an intensity of the input pixel, if the first value is not a
member of the first set of values;
otherwise, a second forming step of forming a second
value from intensities of a second set of pixels around the input
pixel, the second set of pixels including a pixel that is not
included in the first set of pixels;
a second setting step of setting an output pixel
intensity, corresponding to the input pixel, in accordance with
the second value.
