Abstract :
A fast and robust camera´s auto exposure algorithm is proposed by modeling its luminance characteristics as a concave/convex function of a control parameter. A proper parameter value is computed using a modified secant algorithm with fast convergence. The superior performance of the proposed algorithm is confirmed by experimental results.
