ABSTRACT:
For controlling exposure in a camera, first and second brightness levels of first and second areas of a captured image are determined. First and second weight values for the first and second brightness levels are determined with an increase of the first weight value for a higher difference between the first and second brightness levels. Exposure control data is generated from the first and second weight values and the first and second brightness levels.
