Abstract
A system and method of increasing the dynamic range of image sensors by controlling the exposure (either electronically or mechanically) of multiple images and optionally forming a composite image from the properly exposed areas of the multiple images of varying exposure settings. Certain embodiments of the system and method utilize image processing techniques to determine the various exposure settings and to form the optional composite image. The properly exposed areas can be used directly by machine vision applications.
