Title (EN) LONG-TERM HISTORY OF DISPLAY INTENSITIES
(FR) HISTORIQUE À LONG TERME D'INTENSITÉS D'AFFICHAGE
Abstract:
(EN) A data processing system can store a long-term history of pixel luminance values in a secure memory and use those values to create burn-in compensation values that are used to mitigate burn-in effect on a display. The long-term history can be updated over time with new, accumulated pixel luminance values.
(FR) Selon l'invention, un système de traitement de données peut stocker un historique à long terme de valeurs de luminance de pixels dans une mémoire sécurisée, et utiliser ces valeurs pour créer des valeurs de compensation de déverminage qui sont utilisées pour atténuer un effet de déverminage sur un dispositif d'affichage. L'historique à long terme peut être mis à jour dans le temps avec de nouvelles valeurs de luminance de pixels accumulées.
