Colorimetry: Fundamentals and Applications (The Wiley-IS&T by Noboru Ohta, Alan Robertson

By Noboru Ohta, Alan Robertson

Colorimetry, the technological know-how of quantitvely describing colour, is key for colour replica know-how. this is why it creates criteria during which to degree colour, utilizing mathematical ideas and software program to make sure constancy throughout media, permit exact colour blending, and to strengthen colour optimization.This publication is a complete and thorough creation to colorimetry, taking the reader from easy recommendations via to numerous business functions. Set out in transparent, easy-to-follow terminology, Ohta and Robertson clarify basic rules resembling colour specification, the CIE (International fee on Illumination) process, and colour imaginative and prescient and visual appeal types. additionally they conceal the next topics:the optimization of colour reproduction;uniform colour areas and colour distinction formulae, together with the CIEDE 2000 formula;applications of metamerism, chromatic model, colour visual appeal and colour rendering;mathematical formulae for calculating colour blending, maximising luminous efficacy, and designing illuminants with particular properties.Colorimetry: basics and purposes is a perfect reference for training colour engineers, colour scientists and imaging execs engaged on colour platforms. it's also a pragmatic advisor for senior undergraduate and graduate scholars who are looking to collect wisdom within the box.

Example text

In geometric terms, the definitions of photometric quantities are the same as for the corresponding radiometric quantities. Accordingly, the explanations below are made in terms of photometric quantities, but they apply equally well to radiometric ones. For photometric quantities, a subscript v is normally added to the symbol for each quantity, whereas for radiometric quantities, a subscript e is added. 15 illustrates a luminous flux d that passes through two plane elements, A and B. 3) where, dm and dm are the ‘sizes’ of A and B, respectively, and I and I are the ‘densities’ of luminous flux, respectively.

When the eye views a surface of uniform luminance, the number of trolands is equal to the product of the area in mm2 of the limiting pupil (natural or artificial) and the luminance of the surface in cd/m2 . 14) Taking into consideration that 1 mL = 10 / cd/m2 , a surface having a luminance of 1 mL provides a retinal illuminance of 10 td through a pupil having a radius of 1 mm. 7 CALCULATION AND MEASUREMENT OF PHOTOMETRIC QUANTITIES As described above, radiometric quantities can be converted into photometric quantities and vice versa by the equation (photometric quantity) = K × (radiometric quantity).

2, t represents time in seconds (s), represents solid angle in steradians (sr), S represents area in square meters (m2 ), and represents the angle between the normal of the plane element and the direction of observation. The solid angle is expressed in units of steradian, which is defined as the solid angle that, having its vertex at the center of a sphere of radius r , cuts off an area r 2 in the surface of the sphere. Thus, the whole surface of a sphere yields a solid angle of 4 sr because the surface area of a sphere is 4 r 2 .
