Abstract

This paper presents a combinational system, which can perform the functionalities of Auto Focus (AF) and Auto Exposure (AE) at the same time in a very efficient manner. At the first step, this system uses a DOG (Difference of Gaussian) filter to measure image's contrast and sharpness simultaneously. Then, a fuzzy logic-based scheme is proposed for the adjustment of focus and exposure. This system can be easily implemented with low hardware complexity.
