Abstract
An image capturing apparatus performs photographing multiple times and composing these multiple images to obtain one image of a correct exposure. The apparatus includes an image capturing unit, an illumination unit and an image composition unit. The image capturing unit captures an optical image of an object as an electrical signal. The illumination unit performs illumination on photographing by the image capturing unit. The image composition unit composes multiple images obtained by multiple times of photographing by the image capturing unit. All of the multiple images are the images shot by performing illumination with the illumination unit. A light amount of each photographing in multiple times of photographing by performing illumination with the illumination unit is obtained by dividing light amount required for the correct exposure based on the number of photos taken of an image to be composed.
