Title (EN) COMPENSATION FOR PHOTO SENSOR
(FR) COMPENSATION POUR CAPTEUR PHOTOELECTRIQUE
Abstract: front page image
(EN)A method of compensating a photo sensor (and a corresponding photo sensor with compensation) insures the accuracy of the photo sensor, e.g., over environmental variations or photo cell variations. The method comprises: providing a first signal indicative of a light level; providing a second signal indicative of an environmental parameter, e.g., temperature; and calculating, responsive to the first signal and the second signal, a compensated signal that is indicative of an absolute light level. The calculating can be performed by a processor and utilize calibration and compensation information or parameters, which can be obtained experimentally.
(FR)L'invention concerne un procédé de compensation pour capteur photoélectrique (et un capteur photoélectrique correspondant avec compensation) qui garantit la précision du capteur photoélectrique, par exemple, en cas de variations environnementales ou de variations des cellules photoélectriques. Ce procédé consiste à: fournir un premier signal correspondant à un niveau de luminance; fournir un second signal correspondant à un paramètre environnemental, par exemple, la température; et calculer, en fonction des premier et second signaux, un signal compensé qui correspond à un niveau de luminance absolu. Le calcul du signal peut être réalisé par un processeur qui fait alors intervenir les paramètres ou les informations d'étalonnage et de compensation pouvant être obtenus par voie expérimentale.
