Claim:
1. An image capturing apparatus, comprising: a light source; a two-dimensional image sensor that receives reflected light from a subject including specular light of the light source and outputs an image of the subject; and an optical member arranged in an optical path of light emitted from the light source to the subject, wherein when a specular position of the light source in the subject arranged apart from the two-dimensional image sensor by a certain distance is defined as a first specular position, whereas a specular position of the light source in the optical member is defined as a second specular position, a relative positional relation of the optical member and the light source with respect to the two-dimensional image sensor is determined so that a difference between an incident angle from the light source toward the first specular position and an incident angle from the light source toward the second specular position is a reference value, and the reference value is a value with which an optical image of the first specular position and an optical image of the second specular position do not overlap each other on a light-receiving face of the two-dimensional image sensor.
