Abstract
L'invention concerne un procédé de réglage du renforcement d'intensité des élément d'affichage à trame. Elle se rapporte à un procédé selon lequel l'intensité d'éléments d'affichage xp yq est réglée en fonction de la proximité de points XY d'un dessin qui doit être affiché. Des valeurs de pondération, correspondant aux contributions des différents points qui doivent être affichés, sont ajoutées dans chaque élément de trame et permettent un affichage très régulier qui ne présente pas l'effet d'escalier lors de l'affichage d'une ligne faiblement inclinée par rapport à une ligne de trame. Application aux collimateurs de pilotage des aéronefs.
