发明名称 PHOTOMETRIC DEVICE AND IMAGING APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To provide a photometric device having two photometric means, capable of photographing with appropriate light quantity by using either of two photometric means. <P>SOLUTION: The photometric device includes: the first photometric means 14 and 50; the second photometric means 7 and 50; a difference detecting means 50 for detecting a difference between the photometric value of the first photometric means just before switching from the first photometric means to the second photometric means and the photometric value of the second photometric means just after the switching period, or detecting a difference between the photometric value of the second photometric means just before switching from the second photometric means to the first photometric means and the photometric value of the first photometric means just after the switching period; and a storage means 56 for storing the difference detected by the difference detecting means as a correction value, wherein the photometric result is corrected based on the correction value stored in the storage means. <P>COPYRIGHT: (C)2009,JPO&INPIT
