ABSTRACT:
An apparatus and method for controlling a light source that is used during operation of an imaging device (e.g., a camera) and, in particular, during operation of a camera feature/subsystem such as an AF subsystem, a red-eye reduction subsystem, a self-timer subsystem, etc. The apparatus and method include and involve a light source which is configured to emit light in relation to the operation of a subsystem of an imaging device, and a light source control unit which is configured to control an amount of light emitted by the light source based on a preset operating parameter (e.g., a user-selectable camera setting). The apparatus and method may be included within an imaging device such as a camera or in a peripheral (e.g., a flash unit, etc.) configured to operate with such a camera.
