Abstract
(EN)
The invention provides a method for managing image data in an automotive lighting device (10). This method comprises the steps of providing an image pattern (1) and an alternative dataset with a data number lower than the number of pixels, wherein the alternative dataset is related to the values of luminous intensity of the pixels (11). Then, the maximum error is calculated and the alternative dataset is modified to reduce the maximum error, obtaining a modified alternative dataset. The modified alternative dataset is compressed and sent to a light module. The invention also provides an automotive lighting device (10) for performing the steps of such a method.

L'invention concerne un procédé de gestion de données d'image dans un dispositif d'éclairage automobile (10). Ce procédé comprend les étapes consistant à fournir un motif d'image (1) et un ensemble de données alternatif ayant un nombre de données inférieur au nombre de pixels, l'ensemble de données alternatif étant associé aux valeurs d'intensité lumineuse des pixels (11). Ensuite, l'erreur maximale est calculée et l'ensemble de données alternatif est modifié pour réduire l'erreur maximale, ce qui permet d'obtenir un ensemble de données alternatif modifié. L'ensemble de données alternatif modifié est comprimé et envoyé à un module lumineux. L'invention concerne également un dispositif d'éclairage automobile (10) pour réaliser les étapes d'un tel procédé.
