Abstract
A photographic, digital or video camera (10) includes a housing (12); optionally at least one sensor (18, 20, 25, 30, 36, 39, 40, 50) supported by the housing for detecting a condition of the camera or of a scene to be captured by the camera, or both, and for producing a signal; a viewfinder (38) supported by the housing, the viewfinder including a holographic element 64, 90); a source (68) of light having a wavelength of a color to be displayed in the viewfinder; a collimator (70) for receiving a beam from the source and producing an output beam; an optical system (72-80) to horizontally and vertically raster scan the output beam across the holographic element; and a controller (44) for operating the optical system and modulating the output beam in response to the signal, thereby to cause scanned images to be produced by interaction between the output beam and the holographic element, the scanned images displaying information related to use of the camera.
