1. An image capturing apparatus comprising: an image capturing section that includes a first image capturing system and a second image capturing system, the second image capturing system having an image capturing optical axis on a different position from an image capturing optical axis of the first image capturing system and a different image capturing characteristic from an image capturing characteristic of the first image capturing system; a positional relation specifying section that specifies a first positional relation between the first image capturing system and a subject at a first timing at which the first image capturing system has captured an image of the subject; a judging section that judges whether a second positional relation between the second image capturing system and the subject matches more the first positional relation at a second timing than the first timing, based on a displacement of the image capturing apparatus with respect to the subject captured by the first image capturing system, positions of image capturing optical axes respectively of the first image capturing system and the second image capturing system, and the first positional relation; and an image combining section that combines a first image of the subject captured by the first image capturing system at the first timing, with a second image of the subject captured by the second image capturing system at the second timing.
