PROBLEM TO BE SOLVED: To solve the problem in which a method for correcting luminance shading and color shading assuming the use of a camera to which an interchangeable lens can be attached requires a plurality of candidates of parameters having correlation with shading due to various imaging conditions.SOLUTION: An imaging device having an imaging lens optical system, a diaphragm and an imaging element comprises: storage means; calculation means; and correction means. The imaging lens optical system has a single focus. The storage means stores a correction table for calculating a correction term for correcting unevenness of a signal value of captured image data, in association with a focus lens position and a diaphragm diameter. The calculation means reads the correction table corresponding to the focus lens position and the diaphragm diameter when the captured image data is obtained, from among the correction tables, and performs interpolation calculation of the correction term on the basis of the read correction table. The correction means corrects the unevenness of the signal value of the captured image data by using the correction term calculated by the calculation means. |
