摘要：
A glossiness determining device includes: a light source; a two-dimensional sensor that receives reflected light containing a specular reflection component of a subject illuminated by the light source, and outputs an image of the subject; and a determining unit that determines glossiness of the subject by using a saturated image, which is the image of the subject output by the two-dimensional sensor and in which pixel values of a partial area are saturated.
