Patent ID: 7630015

Claim:
A control method of an image sensing apparatus which has a flash unit adapted to emit light in accordance with brightness of an object in a flash photography and can continuously capture a plurality of flash photographs in a single photographing operation, the control method comprising: (i) a photometry step of acquiring a photometric value of the object; and (ii) a control step of determining a light emission amount of the flash unit in the flash photography, wherein, when the plurality of flash photographs are continuously captured in the single photographing operation, said control step determines: (a) a light emission amount of a main emission of the flash unit in a first flash photograph based on a photometric value obtained during a pre-emission of the flash unit in the first flash photograph and a photometric value in a non-light emission of the flash unit prior to capturing the first flash photograph, and (b) a light emission amount of the main emission of the flash unit in a second flash photograph based on the photometric value in the main emission of the flash unit obtained during the first flash photograph and a photometric value in the non-light emission of the flash unit after capturing the first flash photograph and immediately prior to capturing the second flash photograph.
