Abstract

PURPOSE:To ensure a simple measurement of the substance color under the standard light, by storing rixedly and previously the data corresponding to the three exciting values of the standard light, obtaining the error between the data and the exciting value through the characteristic measurement of the CIE standard color measurer and then obtaining the chromaticity point based on the error. CONSTITUTION:The data corresponding to the three exciting values of the standard light C are stored fixedly into the constant voltage sources E2, E4 and E6 each. On the other hand, the measuring light source PC' (lambda) which is similar to some extent to the spectral energy distribution PC (lambda) of the light source PC of the light C is measured by the light receiver S' having the spectral sensitivity similar to the spectrum three exciting value of the CIE standard color measurer. Then the error is calculated between the data corresponding to the three exciting values of the measurement result and the data stored fixedly to be stored into the capacitors C0, C2 and C4 each. Then the substance is measured by the receiver S' and under the illumination of the light source PC'. Thus the chromaticity points (Xcr and Ycr) are obtained from the data calculated and stored and the measured value of the substance when the measurement is carried out by the light receiver S having the spectrum three exciting values of the CIE standard color measurer and with the substance to be measured illuminated by the C light source PC.
