Abstract
An underwater camera housing for enclosing a camera for use with a flash unit has a cable connector to which a signal-transmitting cable extending to the flash unit is attached and a link switch is provided on its outer surface by which the transmission of signals through the cable can be cut off or connected again. The signal transmitted through the cable may be electrical signals or light signals. If light signals are transmitted from the housing to control the flash unit, a circuit is provided for generating an electrical signal to prepare the camera for flash photography and the link switch serves to control the generation of this electrical signal such that the camera can be prepared selectively either for flash or natural-light photography.
Claims6
An underwater camera housing for enclosing a camera for use with a flash unit, said underwater camera housing comprising:
- a cable connector terminal provided on an external surface, said connector terminal serving to be connected to a cable which is connected to the flash unit for transmitting signals therethrough;
- and
- a switch on said external surface for allowing and disallowing signal transmission between the camera and the flash unit through the cable.
A control unit on an externally facing surface of a water-proof underwater camera housing enclosing a camera therein, said control unit comprising:
- means for connecting an optical cable through which optical signals are transmitted between said control unit and a flash unit;
- means for electrically connecting to said camera;
- means for converting an electrical signal into an optical signal;
- and
- means for selectively allowing and disallowing transmission of signals between said flash unit and said camera.
