ALEXANDRIA, Va., Jan. 26 -- Intel, Santa Clara, Calif., has been assigned a patent (8,358,262) developed by Anil A. Degwekar, Karnataka, India, and David Wyatt, San Jose, Calif., for a "method and apparatus to synchronize backlight intensity changes with image luminance changes."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "An approach for coordinating backlight intensity and image luminance changes. For one aspect, in response to determining that a display-related event has occurred during a vertical frame period indicating a subsequent change associated with at least one of a backlight intensity and a frame buffer palette is to be undertaken, an interrupt is enabled. During subsequent interrupt processing, associated changes to the backlight intensity and the frame buffer palette are applied in a coordinated manner. For a specific implementation, an approach is provided for a graphics controller driver to synchronize response to changes in display backlight, color-space controls, and in the luminance of images, wherein said changes can come from different sources, occur at a different rates, and have different latencies, for the purpose of applying graphics settings responses such that those effects occur at a visually co-incident interval so as to substantially minimize discordant visual artifacts."
The patent application was filed on June 30, 2004 (10/882,446). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=8,358,262.PN.&OS=PN/8,358,262&RS=PN/8,358,262
