Abstract
The present invention describes a method and an apparatus for eliminating image artifacts due to imaging of post spacers, or other small clusters of pixels that deviate from nominal performance of light valve technology. This invention is applicable to imaging technologies whose pixels are separately addressable.
Claims29
A method for improving the perceived uniformity of image intensities that deviate from nominal operating conditions, the method comprising:
- supplying a data stream;
- determining a pixel address for each pixel of said data stream;
- separating said data stream into post image data and non-post image data;
- correcting said post image data;
- and
- combining said non-post image data and said corrected post image data into output data.
An apparatus for improving the perceived uniformity of image intensities that deviate from nominal operating conditions, the apparatus comprising:
- means for supplying a data stream;
- means for determining a pixel address for each pixel of said data stream;
- means for separating said data stream into post image data and non-post image data;
- means for correcting said post image data;
- and
- means for combining said non-post image data and said corrected post image data into output data.
A computer program device readable by a machine, tangibly embodying a program of instructions executable by a machine to perform method steps for improving the perceived uniformity of image intensities that deviate from nominal operating conditions, the method comprising:
- supplying a data stream;
- determining a pixel address for each pixel of said data stream;
- separating said data stream into post image data and non-post image data;
- correcting said post image data;
- and
- combining said non-post image data and said corrected post image data into output data.
