| http://www.w3.org/ns/prov#value | - To prevent a yellow line from being detected erroneously as noise, the difference between the maximum value in lightness (255) and one of the values in lightness output from the line sensors other than line sensor 213B, i.e., line sensors 213R and 213G, reading a color complementary to blue, or yellow, can be set as Ref2(R), Ref2(G).
