A plurality of types of interchangeable lenses having mutually different optical parameters required for identifying the optical correction values can be attached to the image capture apparatus. First, predetermined optical parameters are obtained regardless of what type of interchangeable lens is attached. Furthermore, in the case where the type of the attached interchangeable lens is a type that requires different optical parameters than the predetermined optical parameters for identifying the optical correction value, the necessary optical parameters are obtained. The optical correction value is identified based on the type of the attached interchangeable lens using the predetermined optical parameters, other optical parameters, and so on, and optical correction is then carried out.

Each pixel has an organic layer that includes a photoelectric conversion layer. On the basis of the shading characteristics, the correction control section sets the number of operations of signal reading of peripheral pixels such that the number is greater than the number of operations of signal reading of central pixels, and generates image data from the signal of each pixel stored in the signal storage section.
