ABSTRACT:
A method and system for light beam communication between a camera and a computer is provided by adapting an existing light beam auto-focus system of a conventional automated camera, such as a conventional automated film-based camera or a conventional automated electronic camera, and by adapting a conventional computer to provide a light beam communication linkage with the adapted camera. The light beam auto-focus system of such automated cameras is modified to include a mode selector providing a selection of the conventional light beam auto-focus mode and alternatively for selection of a light beam communication mode. The camera has a microprocessor and an erasable electrically programmable read-only memory (EEPROM). In the light beam communication mode, a light beam emitter driver circuit and a light beam sensor timing circuit and signal processor are provided. A conventional computer, for example, a desktop computer or a laptop computer, is adapted to receive and to transmit optically encoded digital signals whereby a computer-based light beam sensor and light beam emitter have an optical spectrum overlapping with the optical spectrum of the camera-based light beam emitter and light beam sensor. Light beam communication is initiated by suitable commands provided by a camera user to the computer. The camera microprocessor is responsive to such commands, and that response is transmitted by the camera-based light beam emitter back to the computer-based light beam sensor.
