The spatial light modulator includes a two dimensional array of pixels. The method includes receiving signals containing pixel image data and processing the pixel image data to determine a desired gray scale for a pixel. The desired gray scale is compared to achievable gray scales of the digital image projection system. An upper bounding achievable gray scale is determined, and a lower bounding achievable gray scale is determined. Also, a dithering percentage for the desired gray scale is determined. The method chooses one of the upper bounding achievable gray scale and the lower bounding achievable gray scale. Also, a modified lower bounding gray scale is chosen to reduce the dithering percentage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus for diffraction artifact reduction in image display systems","description":"For an example method of reducing diffraction artifacts in a displayed image from a digital image projection system, a digital controller is coupled to a spatial light modulator.
