Paper Abstract

All imager arrangements degrade gray value pictures by their photo-response nonuniformity. This paper describes an adequate correction procedure. It is applicable in the case of rapidly changing image sequences containing a homogeneous background. As such systems are of interest in real-time applications, a detailed hardware design, including an error analysis, is given. Finally, the sources of nonuniformity are localized and illustrated by numerical examples.
