发明名称 SYSTEM AND METHOD FOR CONTROLLING PHOTOFLASH
摘要 A system for controlling photoflash includes a signal processing unit, a calculating unit, a photoflash module and an adjusting unit. The photoflash module includes a capacitor. The signal processing unit is configured for analyzing image information to get a current brightness value of the image, and the calculating unit is configured for calculating a first photoflash time of the photoflash module based on a first voltage value of the capacitor via analyzing the current brightness value. The adjusting unit is configured for adjusting the first photoflash time to get a second photoflash time according to a second voltage value of the capacitor, and outputting the second photoflash time to the photoflash module to control flashing of the photoflash module.
