Method and system for adjusting exposure settings of video cameras

摘要

A system and method to enhance dark areas of a scenes while preventing bright areas of the scenes from distorting or skewing exposure settings of video cameras. The video cameras capture images and identify bright areas in the captured images. The video cameras calculate exposure settings while excluding the bright areas in the captured images to enhance the dark areas in the captured images. Camera control parameters are then adjusted based on the calculated exposure settings.
