PROBLEM TO BE SOLVED: To provide a method of controlling the flash time of an external flash lamp.SOLUTION: A method of controlling the flash time of an external flash lamp is used when an external flash lamp is combined with a mobile device to supplement light during photographing. The mobile device has a N-row photosensitive member, and N is a natural number. The method includes inspecting a specific event. An occurrence time of the specific event is opposed to that an exposure start time of a first row photosensitive member is a fixed time length. Whether a single flashable period is present or not is determined, and flashing in this period can be received by a photosensitive member in each row. When the single flashable period is present, a message generated by the specific event is notified to the external flash lamp, which makes a flash instruction triggered to the external flash lamp after a predetermined delay time elapses since the specific event.SELECTED DRAWING: Figure 7 |
