Appeal No. 2002-1457
Application No. 09/047,315
subsequent rendering on an output device having the same lower
resolution as the source data. The synthesized higher resolution
data is rendered such that dots represented by the synthesized
data are formed interstitially relative to the scan lines as
determined by the given lower resolution capability of the output
device (specification, pages 6 & 7).
Representative independent claim 1 is reproduced as follows:
1. A method of rendering raster image data on an
imaging device having a given raster capability, the method
comprising:
(a) receiving raster image data defined at a
resolution less than or equal to the given raster capability
of the imaging device;
(b) converting the raster image data to a
resolution format greater than the given raster capability
of the imaging device thereby forming increased resolution
format image data; and,
(c) rendering the increased resolution format
image data with the imaging device in a manner such that at
least one dot represented by the increased resolution format
image data is formed interstitially relative to scan lines
defined by the given raster capability of the imaging
device.
