Patent ID: 8412359

Claim:
A light control method for automatically rendering a lighting scene with lighting system, comprising: monitoring the rendered lighting scene for the occurrence of an interference, comprising: scanning the rendered lighting scene including taking samples at given measurement points over a period of time; and detecting a significant deviation of the scanned lighting scene with respect to a reference lighting scene by processing the samples including comparing the samples with reference values, wherein the comparing comprises one of the following: averaging over regions of interest a computed difference between readings of a user-tuned lighting scene and the rendered lighting scene, low-pass filtering the computed difference, and comparing the low-pass filtered computed difference with a threshold value in order to determine whether a significant variation in the mean of samples has occurred during the last observed periods of time; or defining a time window embracing the last periods of time previous to a current sample, estimating a predictor from the samples taken during the defined time window, running a generalised likelihood ratio test, and comparing the result of the generalised likelihood ratio test with a threshold value in order to determine whether a change has occurred in the monitored magnitude over a certain region of interest; and automatically reconfiguring the lighting system such that a monitored occurrence of an interference is compensated.
