Title (EN) CHROMATICITY ADAPTATION
(FR) ADAPTATION DE CHROMINANCE
Abstract:
(EN) A transparency viewing device including a faceplate adapted for mounting at least one transparency having a particular density at a portion thereof, a source of back illumination for the transparency and a controller which varies the chromaticity of the back illumination based on the particular density. Preferably, the controller varies the chromaticity based on the chromaticity of the transparency. Additionally or alternatively, the controller locally varies the chromaticity.
(FR) L'invention se rapporte à un dispositif de visualisation de transparents comprenant une plaque frontale conçue pour se fixer à au moins un transparent présentant une densité particulière sur une de ses parties, une source de rétro-éclairage destinée au transparent et un régulateur qui modifie la chrominance du rétro-éclairage en fonction de la densité donnée. De préférence, le régulateur modifie la chrominance en fonction de la chrominance du transparent. Eventuellement, le régulateur modifie localement la chrominance.
