Camera with adjustable strobe energy

摘要

A camera adjusts its strobe energy to achieve proper exposure of a photograph. The adjustment method uses two trial exposures of the scene to be photographed. One trial exposure is taken without the camera strobe using only ambient illumination. The other trial exposure is taken using the camera strobe at a pre-set energy level. Pixels that appear as saturated in the ambient-only trial exposure are discounted in the determination of the strobe energy for the final photograph. This method properly exposes scenes which themselves contain bright light sources such as lamps or light fixtures.
