ABSTRACT:
A spatial light modulator based imaging system (30) with improved peak white performance characteristics. The apparent dynamic range of the spatial light modulator (74) is increased by adding light to pixels neighboring a saturated pixel. An apparent bloom effect is created with the pixels neighboring the saturated pixel appearing brighter, to give sunlight reflecting from the surface of a lake, for instance, more sparkle or highlights. Charts or equations are utilized to determine the degree to which pixel brightness is increased for neighboring pixels. The closer a pixel to a saturated pixel, and the greater the saturation of a particular pixel, the greater increase in brightness for neighboring pixels.
