Abstract[English]
The present invention provides a method that enables the calculation of non-uniformity correction coefficients for an imaging device, a non-uniformity correction method using the obtained coefficients, and an imaging device implementing this method. The method in question includes the steps of obtaining an average output value function for raw output values of at least F homogeneous images, each with different light intensity values; obtaining a desired output value function by expanding the obtained function to a range between zero and a predetermined desired value; calculating correction coefficients for each pixel element by fitting a sigmoid function to this function.[French]
La présente invention concerne un procédé qui permet le calcul de coefficients à des fins de correction de non-uniformité pour un dispositif d'imagerie, un procédé de correction de non-uniformité utilisant les coefficients obtenus, et un dispositif d'imagerie mettant en œuvre ce procédé. Le procédé en question comprend les étapes consistant : à obtenir une fonction de valeur de sortie moyenne pour des valeurs de sortie brutes d'au moins F images homogènes, chacune ayant différentes valeurs d'intensité lumineuse ; à obtenir une fonction de valeur de sortie souhaitée par expansion de la fonction obtenue à une plage comprise entre zéro et une valeur souhaitée prédéterminée ; à calculer des coefficients de correction pour chaque élément de pixel par ajustement d'une fonction sigmoïde à cette fonction.
