Exposure is an important parameter to evaluate image quality.Due to the impact of light sensitivity
automatic gain and other effects
a nonlinear auto-exposure algorithm based on iris control is designed by extracting the brightness of image block and measuring the nonlinear relationship between the size of the aperture diameter and brightness.Experiments show that the nonlinear auto-exposure algorithm using iris control can achieve accurate and fast exposure and has good stability.
