<P>PROBLEM TO BE SOLVED: To more exactly measure the spectroscopic state of a subject even when luminance is low and also to achieve accurate focus detection. <P>SOLUTION: The photometric device is equipped with: a diffusion optical member 105 arranged in the optical path of a photographic lens and having a diffusion surface; a light receiving device 110 receiving diffused light passing through the diffusion surface, and equipped with a first light receiving part and a second light receiving part whose receivable light energy is smaller than that by the first light receiving part. The first light receiving part and the second light receiving part are arranged so that parallax to the optical axis of the photographic lens may be smaller in the second light receiving part than the first light receiving part. <P>COPYRIGHT: (C)2008,JPO&INPIT |
