Claim:
1. An imaging device comprising: a light source that emits light; a two-dimensional image sensor that receives reflected light from a subject containing specular light of the light source and outputs an image of the subject; a light transmission member disposed in an optical path of light emitted from the light source to the subject; and a light shielding unit disposed in a part of an optical path of light emitted from the light source to the light transmission member, wherein a first specular position is a position on the subject at which light from the light source is reflected and enters the two-dimensional image sensor, wherein a second specular position is a position on the light transmission member at which light from the light source is reflected and enters the two-dimensional image sensor, and wherein the light shielding unit shields light from the light source directed toward the second specular position without shielding light directed from the light source toward the first specular position.
