METHOD AND APPARATUS FOR IMPROVING IMAGES PROVIDED BY SPATIAL LIGHT MODULATED (SLM) DISPLAY SYSTEMS

摘要

PROBLEM TO BE SOLVED: To improve images provided by spatial light modulated (SLM) display systems.SOLUTION: The invention provides a method and system for reducing distortion in images provided by display systems (100) employing spatial light modulating (SLM) elements. The method comprises steps of providing a set (620) of pixel values corresponding to pixels of an image to be displayed. The number of pixel values comprising the set is greater than the number of available SLM elements. At least some of the pixel values are adjusted to provide a set (678) of adjusted pixel values. At least a first set of pixels and a second set of pixels are generated from the set of adjusted pixel values. The image is displayed as a matrix (450) of pixels comprising the first set (410) of pixels and the second set (430) of pixels. At least one of the pixels of the first set of pixels overlaps at least one of the pixels of the second set of pixels and the adjusting step is carried out by adjusting pixel values of the set of pixel values to compensate for image distortion due to overlapping pixels of the matrix.
