Abstract
A method and circuit for excluding regions from an exposure calculation is described. The method includes obtaining pre-image data representing an image of a scene and dividing the image into a plurality of regions. Regions that contain a predetermined number of bright pixels are identified, bright pixels being pixels that are brighter than a threshold level of brightness. Each region that has at least the predetermined number of bright pixels from the exposure calculation are excluded.
