Image capturing apparatus

An image capturing apparatus, located in an environment medium, the image capturing apparatus comprising:

• a light guide device, having a first surface and a second surface disposed opposite to each other and a sidewall connected between the first surface and the second surface;
• a transparent device, disposed on the first surface of the light guide device;
• an image capturing device, disposed on the second surface of the light guide device;
• a light absorbing layer, covering the sidewall of the light guide device;
• and
• a light source, adapted to emit a light beam, the light beam passed through the light guide device being transmitted toward the transparent device, and being totally reflected by an interface between the transparent device and the environment medium.
