| titleOfInvention | Light detecting apparatus for photographic camera |
| abstract | ABSTRACT OF THE DISCLOSURE Photographic scene light detecting apparatus particularly suitable for use with a camera of the type which includes an electronic control system for receiving an input signal and controlling the firing of an electronic flash at a predetermined time after the initiation of an exposure interval. The apparatus includes a photodetector and an optical system by which scene radiation can be collected from a predetermined field of view and directed along an optical path onto the photodetector which operates to provide an output signal for use as the input signal to the camera electronic control system. A blade apparatus operates to selectively block and unblock the optical path to the photodetector such that the photodetector receives scene radiation from one region of the scene prior to the firing of the electronic flash and from another region of the scene in correspondence with the firing of the electronic flash. |
