Abstract
A method and system for automatically adjusting an iris opening in an imaging system. The method includes an iterative process that continues to adjust the camera's iris opening until an algorithm stopping condition is met. More particularly, a processor determines a brightness for the image at the current aperture setting. The processor classifies the image according to one of at least two brightness regime classifications. Based on the classifying step, the processor selects a pre-set optimal brightness parameter. The processor compares the brightness value of the image to the pre-set optimal value. The camera's iris opening is automatically adjusted based on a formula that takes into account, the current f-stop setting, the current brightness value, and the optimal brightness value. The iterative process continues until an algorithm stopping condition is met.
