Paper Abstract

The dynamic range of a scene is usually higher than the dynamic range of the sensor used to acquire the image. Design optimizations must be found that increase the intra-scene dynamic range a sensor can achieve. Good dynamic range is necessary to image a scene with the required details and contrast in a single image. The first topic addressed by the paper is the definition of intra-scene dynamic range. The paper will detail past and present techniques to increase the dynamic range of snapshot CMOS image sensors and show the necessary future developments in high dynamic range imaging. The technologies shown are used by various image sensor manufacturers, only a portion thereof are used in Melexis devices.
