发明名称 撮像装置及び測光値の演算方法
摘要 <P>PROBLEM TO BE SOLVED: To shorten time required for photometry when brightness is low. <P>SOLUTION: Photometry means is rest so that an output value from the photometry means for measuring light of a subject has a predetermined value. A photometry value is estimated based on a first output value of the photometry means when the reset is carried out, a second output value of the photometry means when a first time has elapsed after the reset, and a third output value of the photometry means when a second time longer than the first time has elapsed. <P>COPYRIGHT: (C)2013,JPO&INPIT
