An algorithm is proposed for the spectral and colorimetric characterization of digital still cameras (DSC) which allows them to be used as tele-colorimeters with CIE–XYZ color output, in cd/m2. The spectral characterization consists in the calculation of the color-matching functions from the previously measured spectral sensitivities. The colorimetric characterization consists in transforming t...

Brown, Richard W. (National Animal Disease Laboratory, Ames, Iowa). Color of cultures of Staphylococcus epidermidis determined by spectral reflectance colorimetry. J. Bacteriol. 91:911-918. 1966.-A colorimeter with a reflectance attachment was used to study pigment production by Staphylococcus epidermidis strains grown on a medium containing Trypticase Soy Agar (BBL) and cream. The color of eac...

The paper examined the value system in Philippine firms against the backdrop of Eastern-Western cultural dynamics in East Asia. The Asian milieu presents co-existence of cultural stasis and unease -balance and tension between Eastern values and Western ideas. Successful Asian countries demonstrated their ability to blend conflicting cultures and highlight certain values in order to promote nati...

The Four-Color Method was developed to improve the accuracy of tristimulus colorimeters for measurements of color displays. It was verified that the method works well for cathode ray tubes (CRTs). The accuracy of this method has been studied further for spectral variations of displays including CRTs, liquid crystal displays (LCDs) and organic light emitting diode (OLED) displays. A theory for a...

Threshold limit values (TLVs) are intended to protect workers from the severest effects of thermal stress and to establish the exposures to heat in working conditions. Earlier, acute heat strokes often occurred as a result of working in hot environments in Japan. However, acute heat strokes recently sometimes occurred in outdoor work environments such as industrial constructions and agriculture...

the proposed algorithm suggests a new method for determination of k/s value of primaries based on linear least squares technique. by applying the matrix pseudoinverse, a modification is introduced to eliminate the limitation on the numbers of applied dyes in one – constant kubelka-munk theory. the selection of dyes for tristimulus matching are also done on the basis of the initial spectrophotom...

The magnitude of nonconstant luminance errors This note outlines the magnitude of the errors introduced by the failure of contemporary video systems to adhere to the Principle of constant luminance. I assume that you are familiar with chapters 5 through 9 of my book, and that you are aware of the ambiguity and confusion in television engineering concerning the term luminance. I express signal p...
