Patent ID: 6904233

Claim:
A system which performs preliminary emission before main emission in strobe light photographing, comprising: a photometry unit which splits light reflected by an object to be photographed by preliminary emission into a plurality of regions and performs photometry; a first calculation unit which calculates first photometry data from a photometry value obtained in a predetermined region out of a plurality of photometry values obtained by said photometry unit; an object distance detection unit which detects object distance information on a distance to the object; a second calculation unit which calculates proper second photometry data corresponding to the object distance information; a third calculation unit which calculates third photometry data from calculation results of said first and second calculation units and a contribution corresponding to the object distance information and a precision of the object distance information; and a control unit which controls an main emission amount and performs strobe light photographing on the basis of a calculation result of said third calculation unit.
