Abstract

L'invention concerne un procédé et un appareil permettant d'éliminer les traces tactiles sur un écran à commande tactile, ainsi qu'un support de stockage lisible par ordinateur. Le procédé comprend les étapes suivantes : (S1) acquérir la luminosité d'une zone cible, la zone cible étant une zone pressée d'un écran à commande tactile ; (S2) déterminer une valeur d'échelle de gris de compensation de la zone cible en fonction de la luminosité de la zone cible ; et (S3) en fonction de la valeur d'échelle de gris de compensation, déterminer une tension de compensation pour la zone cible de manière à effectuer une compensation de tension. Des traces tactiles sombres formées par un glissement ou une pression ponctuelle peuvent ainsi être éliminées rapidement et efficacement, ce qui permet d'améliorer l'effet visuel.
