发明名称 Camera with means for allowing photography under low light conditions
摘要 A standard camera with means for using non-imaging light for activating the film when taking pictures in low light conditions. The film activating means consists of an LED strip mounted on the primary blind or blade of a focal plane shutter of a standard camera, and placed adjacent to the trailing edge thereof. The LED strip is illuminated when the shutter mechanism is activated and the strip will be moved across the film gate area to activate the film just before the light from the subject strikes the film to produce the image thereon. In this manner, none of the subject light is used for activating the film and a better picture results. The LED light can comprise three lights of blue, green and red and the brightness of these three lights may be individually controlled to obtain different photographic effects on the film.
