Abstract:
A digital camera having a continuous photography mode, comprising:an image sensor for sensing an image of an object; a light emission device for illuminating the object during a photographing operation; a chargeable power source for supplying power to the light emission device; an adjustor for adjusting a gain of an output of the image sensor; a determining portion for determining an amount of light emission of the light emission device for the photographing operation; a charge time calculator for calculating a charge time, needed after light emission, of the chargeable power source based on the thus determined amount of light emission; a discriminator for discriminating whether or not a frame speed in the continuous photography mode would be reduced based on the thus calculated charge time; and a gain controller for controlling the adjuster so as to increase the gain when it has been discriminated that the frame speed would be reduced.
