Abstract: A microprocessor based strobe controller provides an interface between a digital camera and one or more strobe units. The strobe controller provides interoperability and enhanced user control by enabling the user to vary separately the light output of a variety of strobes of different manufacturers. The strobe controller enables a user to take pictures using digital TTL manual bracketing based on TTL feedback and full manual operation with the ability to adjust light output over a plurality of power levels with any TTL strobe. The strobe controller may be incorporated in a housing for operatively enclosing a digital camera for use underwater or in harsh environments. The housing provides a communication link between the camera and one or more strobes, and includes an intuitive user interface that accesses camera functions, strobe controller functions and gives visual strobe control feedback.

Abstract: A method and apparatus for activating a remote light source in synchronization with an indication provided from a camera. A transducer is coupled to the external electrical connector of a conventional camera in order to convert the electrical signals that are output from the camera into an alternative form (e.g., optical signals). A different transducer is coupled to the external electrical connector of a remote light source, such as a photographic strobe. The light source transducer receives the signal from the camera transducer and converts the signal back into one or more conventional electrical signals to activate the remote light source. A light source activation signal and a light source modulation signal are multiplexed onto a single communication channel. A first indication is provided on the communication channel to activate the remote light source (i.e., cause the remote light source to emit light).
