Intel Assigned Patent for Method and Apparatus to Synchronize Backlight Intensity Changes with Image Luminance Changes
(Targeted News Service Via Acquire Media NewsEdge) By Targeted News Service
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
