Abstract
The present invention is directed to a flashing control method for a digital camera. Indices respectively corresponding to sensitivity values are firstly determined. Subsequently, main-flash intensities are respectively obtained with respect to the sensitivity values such that their target brightness values are substantially the same after exposure, thereby constructing an energy table. Further, a predetermined preflash is fired to obtain a corresponding preflash brightness value with respect to each distinct distance. Main-flash indices are then respectively obtained according to maximum main-flash intensity and the energy table with respect to the distinct distances such that the target brightness values are substantially the same after exposure, thereby constructing a preflash table. During picture capturing, the main-flash intensity is obtained according to the preflash brightness value and the preflash table.
