A device and process which eliminates potential moire patterns in
digitized images by employing a one-dimensional sensor array and a
sampling method of the sensor signals which produces a data set of
non-uniformly spaced sensor positions. This allows the spacing of the
sensors to avoid having a strong "harmonic" which may interfere with
details or harmonics present in the image source, which eliminates the
occurrence of moire patterns and the need for application of image
processing to remove moire patterns. Sensors are non-uniformly spaced
along a first axis according to a predetermined scheme or function.
Sensors are sampled during scanning according a non-uniform function in
order to realize a non-uniform sampling scheme in a second dimension.
Linear interpolation is applied to the non-uniformly spaced data set,
synthesizing a uniformly-spaced data set for use in common imaging
formats and processing.
