CA 2433279

A method for simulating in a digital image the effect of a physical polarization filter is described, the digital image having a plurality of pixels (50) with color, by darkening (54) each of the plurality of pixels (52) having a cool color and lightening (56) each of the plurality of pixels having a warm color. Optional adjustment algorithms are disclosed, including a contrast adjustment (62), saturation adjustment (64) and intensity adjustment.

L'invention porte sur un procédé simulant dans une image numérique en couleur présentant de nombreux pixels (50) l'effet d'un filtre physique de polarisation en noircissant (54) les pixels (52) de couleur froide et en éclaircissant (56) les de couleur chaude. L'invention porte également sur des algorithmes facultatifs de réglage dont celui du contraste (62), de la saturation (64) et éventuellement de l'intensité (66).
