ABSTRACT:
A camera having a pointing aid emitter that produces a visible beam generally aligned with the optical axis of the camera objective lens such that the visible beam illuminates an object in the scene includes a scene measurement system that measures an aspect of the scene and an emitter controller that adjusts the output power of the pointing aid emitter in accordance with the scene aspect measured by the scene measurement system to reduce power consumption and reduce the risk of damage to the object that is illuminated by the beam. The scene measurement system of the camera preferably comprises an ambient light measuring system of a camera automatic exposure system and a distance measuring system of a camera automatic focus system. The emitter preferably comprises a laser light source that produces a visible laser beam.
