Television scene lighting consistency index8 Ermine Close, Stamford, Lincs PE9 2XW, UK
Woodside, Little Hill, Orcop, Herefordshire HR2 8SE, UK A brief account is given of the Television Consistency Index method for assessing the colorimetric properties of light sources for use in television scene lighting. Theoretical limits have been determined within which this index may be used as a general description of lamp performance, bearing in mind the inevitable differences in spectral analysis characteristics (spectral sensitivities) which exist between one colour television camera and another. Practical comparisons between displayed colour television scenes are described, in which the original scenes were illuminated by different lamps, and the results of these tests are discussed in relation to corresponding Television Consistency Index and General Colour Rendering Index values.
