Abstract
In an exposure control apparatus for a vehicle-installed camera which captures images of an external scene ahead of the vehicle as respective arrays of picture elements, highest-brightness and lowest-brightness picture elements of each image are excluded from processing for measuring the brightness of a region in the scene ahead of the vehicle, thereby enabling stable measurement of brightness with reduced effects of incident light from oncoming vehicle headlights, dark patches on the road surface, etc.
