Abstract | The invention relates to a method for designing color filters which improve or modify color vision of the human eye. According to the invention a desired opponent signal function to be attained is divided by a real opponent signal function characteristic of the eye color vision to be improved or modified, the negative range of the resulting function is replaced by zero, the whole function is normalised to give a spectral transmission function, and, if desired, one or more section(s) of this spectral transmission function is modified. The invention also relates to color filter means designed by the above method.
La présente invention concerne un procédé de conception de filtres couleur qui améliorent ou modifient la vision des couleurs par l'oeil humain. Selon cette invention une fonction de signal opposé que l'on souhaite atteindre est divisée par une caractéristique de fonction de signal opposé réelle de la vision des couleurs de l'oeil à améliorer ou modifier, la plage négative de cette fonction résultante est remplacée par zéro, la fonction entière est normalisée de façon à donner une fonction d'émission spectrale et, si on le souhaite, une ou plusieurs parties de cette fonction d'émission spectrale sont modifiées. Cette invention concerne aussi un filtre couleur conçu par le procédé susmentionné. |
