Abstract
An image capturing apparatus illuminates and captures an image of an object using reflected light therefrom, with simplified distance measurement. A plurality of light-emitting devices are mounted around an image sensor, and a light guide member guides the light of the light-emitting devices to an image capturing region for illumination. The image capturing apparatus having the closely disposed image capturing system and illumination system, further has a distance-measuring light-emitting device and an aperture on the distance-measuring light-emitting device and for generating an optical path having narrowed downside and broadened upside. Thus, diffused reflected light rays of distance-measuring light-emitting device can be selected, converged and output to one direction. It becomes possible to obtain sufficient irradiation amount even when using a power-saving light-emitting device of a small emission amount, and to miniaturize a distance sensor irradiating spot light, contributing to miniaturization of the image capturing apparatus.
