Abstract: First and second measurement operations are performed according to each of a plurality of geometric conditions while keeping the geometric condition. In the first measurement operation, illumination light is radiated from a first light radiating position toward a measurement target position and spectroscopic measurement is performed on reflected light traveling from the measurement target position toward a first light receiving position. In the second measurement operation, illumination light is radiated from a second light radiating position toward a measurement target position and spectroscopic measurement is performed on reflected light traveling from the measurement target position toward a second light receiving position. The two spectroscopic measurement results are averaged. The second light radiating position and the second light receiving position are respectively disposed symmetrical to the first light radiating position and the first light receiving position with respect to a reference axis.

Abstract: Colorimeter having first and second illumination units disposed symmetrically to a reference line in a prescribed plane, first and second light-receiving parts disposed symmetrically to the reference line in the prescribed plane, a calculation unit for determining color information about a measurement object, and an opposing wall that opposes the measurement object when it is measured. The opposing wall has an abutting part that abuts the measurement object when it is measured. The abutting part has a pair of first abutting parts disposed on two sides of a measurement opening to flank the measurement opening; and a pair of second abutting parts disposed on an orthogonal line orthogonal to a first-abutting-part connection line that connects the pair of first abutting parts to each other, the pair of second abutting parts being disposed on two sides of the first-abutting-part connection line to flank the first-abutting-part connection line.
