Abstract

A device includes a light source; a first guiding unit that guides the light from the light source to an object at prescribed incident angles including a first incident angle and a second incident angle; a signal generating unit that receives light and that generates an image signal based on the received light; a second guiding unit that guides the light reflected from the object to the signal generating unit; and a control unit that controls the first guiding unit to guide the light from the light source to the object at least two different incident angles including the first incident angle and the second incident angle, and controls the signal generating unit to generate image signals for the at least two different incident angles.
