Lighting method and system to improve the perspective colour perception of an image observed by a user

摘要

A lighting method for illuminating an environment by means of a plurality of light sources is comprised of the following steps: acquiring a video signal, in which an image of each frame is divided into a plurality of boxes; subdividing the video signal into a plurality of video signal boxes, each associated with an image portion of each frame displayed on a respective box; processing frequency of the frame video signals, for obtaining spectra of respective luminance and chrominance signals associated with each video signal box; extracting a dominant frequency band of the luminance signal spectrum associated with each box video signal; extracting a dominant frequency band of the chrominance signal spectrum associated with each box video signal; summing the processed spectra of luminance and chrominance signals; and obtaining a time driving signal of each of the light sources.
