Abstract
The disclosed measuring apparatus can measure a predetermined physical quantity (e.g., temperature) of a coloring member (e.g., liquid crystal) whose color condition changes according to change of the physical quantity. The measuring apparatus comprises: a coloring member (2) whose color condition changes according to change of a predetermined physical quantity; a color detecting section (5) for detecting the color condition of the coloring member; a data base section (8) for constructing a three-dimensional color space (10) having three coordinate axes each corresponding to each of tristimulus values of color of the coloring member, relationship between the predetermined physical quantity and the tristimulus values being represented in the three-dimensional color space; and a physical quantity calculating section (9) for calculating the physical quantity of an object (1) to be measure on the basis of the tristimulus values of color of the coloring member detected by the color detecting section (5) and with reference to the data base section (8).
