Traitement de bas niveau intégré : Mise en oeuvre d'une adaptation aux conditions lumineuses dans un capteur d'images CMOS
Résumé
This paper proposes a state of the art of works done in our research group on on-chip light adaptive systems. The aim of this system is to provide, at the output of the pixels array and for the same filmed scene, aconstant histogram whatever the mean light condition. Two different architectures are presented and two circuitshave been designed. « Imagyne 2 » proposes a solution for standard CMOS imager applications (webcam, ...).« Imagyne 3 » architecture is more dedicated to industrial applications. These circuits has been designed with aCMOS 0,35Im from AMS.
