ABSTRACT:
A photographic camera with an electrical circuit for generating an electric signal proportional to the relative motion between the object sighted and the camera. The camera has a control circuit which receives the generated signal and provides an output signal which is fed to a display and/or control device. An indicator is provided to the user of the camera for indicating whether the exposure time is set too long for the relative motion present between the object and the camera. Automatic control of the camera is also provided. Individual photosensor elements are arranged in two alternately connected groups within the electrical circuit. The individual photosensor elements may also be arranged in two substantially perpendicular directions to provide a relative motion signal corresponding to two dimensional movement between the object to the photographed and the camera.
