Comparative Assessment of Video Camera Color Reproduction Using Matchman Mk II

The principles of color reproduction in television systems are reviewed in this article, and some of the factors affecting the accuracy of reproduction by color cameras are discussed. Methods for measurement of the colorimetric fidelity of cameras are considered, and it is concluded that while objective techniques offer high precision in colorimetric terms, a method offering subjective comparison is preferred for frequent use by operational personnel. Matchman, a new portable instrument that uses electronic storage to facilitate swift comparison of actual camera reproduction against an ideal reproduction derived from stored reference data, is described. The reference signals are superimposed upon the camera signals in a form that allows subjective comparisons on a single monitor display.
