Abstract

This report considers the options available to characterise imaging luminance and colorimetric measurement devices. These devices use an area array, usually a charge coupled device, as their detector and, in addition, are able to produce their output in the form of images that can be both displayed and analysed. Thus, they are able to derive for example, the spatial distribution of colorimetric and/or photometric information in a scene. Included in this category of device are digital cameras and imaging photometers. Digital cameras used to measure colorimetric coordinates require calibration in a relative sense, a process usually termed characterisation; imaging photometers for measuring luminance require calibration in an absolute sense. It is assumed in this report that the characterisation is to be made spectrally to derive either the relative spectral responsivity and/or the absolute spectral responsivity. A separate report will deal with aspects of digital camera characterisation using coloured test targets of known colorimetry.
