Abstract
A method for taking photo with an extension flash module of a mobile device is provided in the present invention. The mobile device operates in coordination with an extension flash module to achieve fill light while taking photo. The method includes the following steps: detecting a specific event before a flashable period. The flashable period starts from the time at which a last row of photo sensors begins exposure to the time at which a first row of photo sensors ends exposure. The time at which the specific event occurs is a fixed period of time compared to the flashable time. Then, triggering a flash instruction according to a flash delay time and a period from the time at which the specific event occurs to the flashable time, such that the extension flash module flashes during the flashable time.
