Abstract
The present invention relates to a method of processing images obtained from a photosensitive detector of the type notably produced by semiconductor material deposition techniques. The method consists in correcting an image acquired by the detector with a gain image. According to the invention, a temperature gain drift correction image is applied to the acquired image as a function of a temperature measured by the detector during the acquisition of the image. The invention also relates to a photosensitive detector in which the temperature gain drift correction means are included, independently of the gain image.
