摘要: The invention provides a camera automatic exposure method based on ambient brightness and image information entropy. comprises the steps of S1, calculating averagebrightness graph entropy an image; average according to histogram graph; S2, obtaining target through weighted calculation by utilizing basedon information. is already realized in 3559A processor + IMX305 sensor scheme. Tests show that effectively solvesthe problem scene adaptability traditional AE method, good results can be obtained no matter whether wide dynamic scene, high contrast or with rich details are processed, andthe requirements current intelligent security industry field video monitoring fully met.
