ABSTRACT:
A camera (10) has a passive display device, preferably a liquid crystal display panel (26), positioned in front of one edge of the film (24), in the path of light directed at the film from the lens and shutter assembly (12). The display is driven by a clock or other control circuit (28), also in the camera, with controls (30) on the outside of the camera so as to display the date and time, or other selected indicia, continuously, whereby light entering the camera upon taking a picture will cause the display to cast a shadow (40') of the indicia onto the film, thereby automatically to label the film. The clock circuit and display may be arranged as a retrofit device (44-50) for an existing camera. A second display (34) with identical indicia may be arranged to provide a readout in the viewfinder (20) to indicate to the photographer how the labeled photography will appear. The camera may also contain a light source (54) for illuminating the readout from the front thereof. The readout may be mounted in front of the film plane in any of a variety of positions, or a plurality of readouts in a plurality of positions may be employed.
