Abstract
A method of exposure control for an imaging system. A predetermined number of images are captured by one or more imagers, wherein the images are defined by an image resolution matrix. The images are masked to establish a region of interest within the image resolution matrix and brightness of the images is analyzed within the region of interest. An exposure time is calculated for a subsequent image capturing step based on the brightness analysis, and an exposure time setting of the imager(s) is adjusted during the subsequent image capturing step based on the calculated exposure time.
