There is provided a variable reference voltage signal being inversely proportional to a product of an analog gain, a digital gain, and a gamma value of the digital camera. When taking a picture and generating flash, the brightness is detected and, when a voltage signal representing the detected brightness is larger than the variable reference voltage signal, the flash is stopped.
