Patent ID: 7859595

Claim:
A method for extracting and processing video content to be emulated by an ambient light source, using output thresholding, comprising: (1) extracting color information, including an intensity, from a video signal (AVS) that encodes at least some of said video content; and (4) thresholding said color information to control an on/off change of state of said ambient light source initiated after said intensity passes a threshold (T 1 , T 2 ), wherein the control of the on/off change of state of said ambient light source is configured to provide (a) a depiction of dark colors by switching said ambient light source off in response to said intensity falling below the threshold, (b) a reduced on/off flicker for said intensity fluctuating at or near the threshold, and (c) ambient lighting produced by said ambient light source derived from said video content by switching said ambient light source on in response to said intensity rising above the threshold to emulate the video content by providing a perceptual extension of a phenomenon of the same.
