发明名称 PHOTOGRAPHING DEVICE AND EXPOSURE CONTROL METHOD
摘要 <P>PROBLEM TO BE SOLVED: To provide a photographing device capable of performing proper exposure control when performing autofocusing and to provide an exposure control method. <P>SOLUTION: A photographing device (100) includes a photometric part (16) measuring a first luminance of an object, an auxiliary light emitting part (30) emitting auxiliary light to the object, when the first luminance is not enough to perform autofocusing, and a control part (10) performing exposure control for performing autofocusing. The photometric part (16) measures a second luminance of the object after being irradiated with the auxiliary light and the control part (10) sets a value obtained by adding a correction amount corresponding to the kind of the auxiliary light to the second luminance as a third luminance and performs exposure control for autofocusing on the basis of the third luminance. <P>COPYRIGHT: (C)2013,JPO&INPIT
