Patent ID: 7272304

Claim:
An image sensing device which has a light emitting unit for emitting light toward an object or can connect the light emitting unit, comprising: a first instruction unit adapted to issue a pre-light emission instruction by the light emitting unit; a second instruction unit adapted to issue a main light emission instruction by the light emitting unit, said second instruction unit being independent of said first instruction unit; a control unit adapted to receive the pre-light emission instruction of said first instruction unit, determine a light emitting amount upon main light emission by executing an auto-focusing process for an object to attain an in-focus state, performing pre-light emission after the in-focus state is attained, and controlling predetermined photometry means to measure reflected light from the object by the pre-light emission, receive the main emission instruction of said second instruction unit, perform main light emission by driving the light emitting unit in accordance with the light emitting amount, and shoot an image.
