Patent ID: 8917350

Claim:
A method for synchronizing a photographic lighting device to image acquisition by a camera, the method comprising: detecting a predictor signal and/or event; determining an amount of time from the occurrence of the predictor signal and/or event until a desired time for the initiation of light emission of the photographic lighting device; transmitting to the photographic lighting device an instruction for the initiating light emission of the photographic lighting device at the desired time; allowing a first shutter blade of the camera to move such that light is allowed to pass to an imaging portion of an image acquisition sensor of the camera; and initiating light emission of the photographic lighting device, using the instruction, after the first shutter blade begins to expose the image acquisition sensor to light and before X-sync associated with the first shutter blade stopping movement, where said determining an amount of time includes utilization of time value determined using a calibration that includes: initiating an image acquisition sequence; determining a start of movement of a second shutter blade; and using a shutter speed of the image acquisition, a shutter blade travel time for the camera, and a time from the occurrence of the predictor signal and/or event to the start of movement of the second shutter blade to determine the time from the predictor signal and/or event to the stopping of movement of the first shutter blade.
