Abstract:
The proposed automatic exposure algorithm calculated the image's average brightness based on the uniform partion with weight, then controlled shutter and gain by a gradual approximation with different adjusting step-size and achieved a wide range control of automatic exposure based on high definition ip camera. For high definition ip camera's different scene, the results based on TI's davinci platform shows that the proposed algorithm reached good auto exposure effect in normal lit, back lit and excessive front lit. At the same time, algorithm's complexity is reduced and its efficiency is improved.
