摘要:
An image processing circuit/CPU performs AF processing in response to a halfway shutter operation and upon confirmation of a shooting shutter instruction causes a light emitting unit in a flash circuit to emit light, and decides an amount of light to be emitted at a shooting time based on a brightness component of an output signal of an imaging element, whereby a subject distance is calculated from the amount of light emitted at shooting time, and wherein, when the in-focus decision in the AF processing is negative, an optical lens is moved by a lens drive circuit to a position corresponding to the subject distance which has been acquired based on the amount of light emitted at the shooting time, and a shooting operation is then performed.
