<p>The camera system has a lens that is adjustable between a number of lens focus positions, an aperture that is adjustable between a number of openings, a shutter and a flash unit. The ambient light of a scene to be photographed is measured to generate an indicative signal. A signal is generated indicative of whether the ambient light is natural light or artificial light. A controller is responsive to the generated signals to control the opening of the aperture and the operation of the shutter and flash unit.</p> |
