1. An image capturing apparatus, comprising: an image capturing section; an image capturing control section which repeatedly captures an image of different luminance with the image capturing section to provide plural images of different luminance; an image region clipping section which clips each of substantially overlapping image regions of the plural images of different luminance; a composite image generation section which composes each of the image regions clipped by the image region clipping section to generate plural composite images having a wider dynamic range than that of the image captured by the image capturing section; and a wide range image generation section which joins the plural composite images generated by the composite image generation section to generate an image whose range is wider than that of the image captured by the image capturing section.
