Visible light image capturing is performed at appropriate timing that corresponds to the action of a subject. An image capturing system includes: an infrared light image capturing section that successively captures a plurality of infrared light images of a subject, using infrared light; a timing predicting section that predicts timing at which the subject included in the plurality of infrared light images matches a predetermined condition, based on timing at which each of the plurality of infrared light images is captured and image content of the plurality of infrared light images; and a visible light image capturing section that captures a visible light image by using visible light at the timing predicted by the timing predicting section.
