Abstract
A compact through-the-lens digital camera comprising an objective lens unit, an image sensing device, an internal display device, an eye lens unit, an optical system, control and processing circuitry, function select controls, and an external interface. The optical system is switchable between an image framing mode optical path, wherein light is directed from the objective lens unit to the eye lens unit, an image capture mode optical path, wherein light is directed from the objective lens unit to the image sensing device, and an image review mode optical path, wherein light is directed from the display device to the eye lens unit. The control and processing circuitry switches the optical system between the image framing mode optical path, the image capture mode optical path and the image review mode optical path and controls the image capture, processing, storage and display on the display device, the operation of the zoom and auto focus functions and function select controls and external communication through the external interface.
