1. A glossiness determining device comprising:
- 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.

12. A glossiness determination method performed by a glossiness determining device that includes a light source, a two-dimensional sensor, and a determining unit, the glossiness determination method comprising:
-
receiving reflected light containing a specular reflection component of a subject illuminated by the light source and outputting an image of the subject by the two-dimensional sensor; and determining, by the determining unit, 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.
