Publisher's Synopsis
Accurate colour measurement requires that account is taken of light sources, ways in which objects react to the components of the spectrum, and the colour vision properties of human observers. A system that allows for these factors, known as the CIE system, has been internationally agreed and forms the basis of colourimetry.;The aim of this text is to provide an explanation of the CIE system and its recent extensions and improvements, in the context of colour perception and practical colour measurement. It explores and continually emphasizes the relationships between what is measured and what the human eye sees. It shows how various spectral weighting functions are used to obtain measures that identify colours that look alike to the human eye. The book also details the internationally-agreed equations enabling these measures to be transformed into quantities that correlate with various colour perceptions, and with the magnitudes of perceived colour differences.
