Abstract:
1. A method of synchronizing a camera equipped portable media device (CEPMD) having a camera shutter trigger, and an external lighting apparatus (ELA), the method comprising the steps of: 1) providing hardware and software comprising; 2) calculating simultaneously by use of the synchronization software: 3) calculating max errors to verify that the photoflash occurs within a duration between a PFlash_start_earliest time and a PFlash_start_latest time; 4) triggering at a pre-determined time the ELA and the synchronization software during the a T-exposure time to create the photoflash between the PFlash_start_earliest and the PFlash_start_latest time; and 5) capturing the photoflash having a duration of a PFlash_start to a PFlash_end time by enlarging the T-exposure time to a point that the max errors is not greater than the T-exposure time.
