PROBLEM TO BE SOLVED: To solve a problem that accuracy of correction is deteriorated because optical distribution is complicated according to an optical system in the conventional technique. SOLUTION: The photometric device includes: a light receiving means (photometric sensor 113) that divides and receives luminous flux incident through the optical system (zoom lens 102) in a plurality of areas, and outputs a light receiving signal; a storage means (memory 108) that stores a first correction value corresponding to the light receiving signal decided in accordance with the light receiving means (photometric sensor 113) for a first area out of the plurality of areas; a detection means (lens information acquiring part 151) detecting information of the optical system (zoom lens 102); an arithmetic calculation means (second correction part 153) that obtains a second correction value corresponding to the light receiving signal for a second area different from the first area out of the plurality of areas based on the information of the optical system (zoom lens 102); and a correction means (photometry correction part 154) that corrects the light receiving signal based on the first correction value and the second correction value.
