Abstract
An image capturing apparatus includes an image sensor and a focus detector. The focus detector corrects a result of the focus detection by using a difference between a first focus position calculated as a focus position in image capturing by using aberration information of the image capturing optical system and first calculation information according to a spectroscopic characteristic of first light and a second focus position calculated as a focus position in the focus detection by using the aberration information and second calculation information according to the spectroscopic characteristic of the first light, and changes the second calculation information in the focus detection between when second light having a spectroscopic characteristic different from that of the first light is emitted to the object, and when the second light is not emitted.
