1. A method of operating a shutter assembly in a camera, wherein said shutter assembly controls an amount of light incident on a capturing medium when capturing images of a scene, said capturing medium also being contained in said camera, said method being implemented in said camera, said method comprising: receiving a plurality of sets of pixel values, wherein each set of pixel values represents a corresponding image of said scene and is obtained with said shutter assembly configured using a corresponding one of a plurality of sets of exposure parameters; identifying a region of interest forming a part of said scene by processing at least some of said plurality of sets of pixel values, said region of interest having a corresponding level of brightness in each of said plurality of sets of pixel values; determining a first set of exposure parameters to achieve a desired level of brightness based on levels of brightness of pixels in said region of interest in said sets of pixel values and at least one of said plurality of sets of exposure parameters; and generating signals to configure said shutter assembly using said first set of exposure parameters.
