A Brightness Linearization Technique for a Thermal Imager

Abstract

This paper describes the brightness linearization technique used in the video processing for a thermal imager. A wide bandwidth log-antilog circuit is developed. This circuit converts the linear video signal to a power law which directly compensates for the gamma of the cathode ray tube display.
