Abstract
A system and method for controlling one or more remote photographic flash devices from a camera body. Wireless functionality within a camera body provides wireless communication of a signal from within the camera body to one or more remote devices. In one example, a flash synchronization signal of the camera body may be wirelessly communicated using a wireless communication functionality within the camera body and an external antenna to one or more remote flash devices for triggering the one or more remote flash devices.
Claims19
A method for controlling one or more remote photographic flash devices from a camera body, the method comprising:
- electrically receiving a flash synchronization signal internal to the camera body;
- using the flash synchronization signal to generate within the camera body an RF signal;
- communicating the RF signal via a wired connection to an antenna external to the camera body;
- and
- wirelessly communicating the RF signal from the external antenna to the one or more remote photographic flash devices.
A system for controlling one or more remote photographic flash devices from a camera, the system comprising:
- a camera body having wireless communication circuitry within the camera body that does not interfere with the camera body functioning as a camera;
- an electrical pathway operatively connecting the wireless communication circuitry to a control of the camera providing a flash synchronization signal, the wireless communication circuitry configured to generate an RF signal in response to receiving a flash synchronization signal;
- and
- an antenna element external to the camera body, the antenna element connected via a wired connection to the wireless communication circuitry, the wireless communication circuitry configured to communicate the RF signal to the antenna element for wireless communication to the one or more remote photographic flash devices.
A system for controlling one or more remote photographic flash devices from a camera, the system comprising:
- a camera body having one or more camera controls;
- a wireless communication circuitry within said camera body and operatively connected to at least one of said one or more camera controls;
- and
- an external antenna element removably connected to a port on an external surface of the camera body, said port connected via a wired connection to the wireless communication circuitry, said wireless communication circuitry including one or more circuit elements sensing the presence of said external antenna and switching said wireless communication circuitry to an active state when said external antenna is present and to an inactive state when said external antenna is not present.
