1. An image capturing apparatus comprising: an image capturing section that includes a first image capturing system including a first lens having a first image capturing optical axis and a second image capturing system, the second image capturing system including a second lens having a second image capturing optical axis on a different position from the first image capturing optical axis of the first image capturing system and having a different resolution from that of the first image capturing system; a positional relation specifying section that specifies a first positional relation between the first lens 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 lens 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 the first and second image capturing optical axes respectively of the first image capturing system and the second image capturing system, and the first positional relation; an image capturing control section that controls the second image capturing system to perform image capturing at the second timing, when the judging section has judged that the second positional relation matches more the first positional relation at the second timing than the first timing after the first image capturing system has performed image capturing at the first timing; 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.
