Abstract
A system and method for synchronizing a photographic lighting device to image acquisition by a camera using light emission profile information to position a light emission profile at a desired location in an image acquisition window. A light energy balance point of a light emission profile can be used to position the balance point at a desired location in an image acquisition window.
Claims20
A method of synchronizing a photographic lighting device to image acquisition by a camera, the camera generating one or more detectible signals and/or events between a first time at which the camera is triggered to start an image acquisition sequence and a second time at which the camera allows light to pass to an imaging sensor for capturing an image for the image acquisition sequence, the method comprising:
- identifying a balance point of a light emission profile for a photographic lighting device associated with the camera;
- detecting a predictor signal and/or event occurring between the first and second times, the predictor signal and/or event not being a signal or event intended by the camera for instructing the initiation of an X-sync lighting emission;
- based on the detecting of the predictor signal and/or event, wirelessly communicating a wireless signal to the photographic lighting device;
- and
- based on the predictor signal and/or event and the wireless signal, initiating light emission of the photographic lighting device at a third time after the occurrence of the predictor signal and/or event, the third time not being a time at which the camera is configured to provide an X-sync or an FP-sync light emission, the third time being determined using the balance point to position the balance point at a desired location in an image acquisition window.

A system for wirelessly synchronizing a photographic lighting device to an image acquisition by a camera, the system comprising:
- one or more processing elements;
- a wireless communications circuitry;
- and
- one or more memory elements, said one or more memory elements configured with information for instructing the one or more processing elements to:
- identify a balance point of a light emission profile for a photographic lighting device associated with the camera;
- detect a predictor signal and/or event occurring between the first and second times, the predictor signal and/or event not being a signal or event intended by the camera for instructing the initiation of an X-sync lighting emission;
- based on the detecting of a predictor signal and/or event, use the wireless communications circuitry to wirelessly communicate a wireless signal to the photographic lighting device;
- and
- based on the predictor signal and/or event and the wireless signal, initiating light emission of the photographic lighting device at a third time after the occurrence of the predictor signal and/or event, the third time not being a time at which the camera is configured to provide an X-sync or an FP-sync light emission, the third time being determined using the balance point to position the balance point at a desired location in an image acquisition window.
