Today's camera professional requires unheralded flexibility in the capturing of color television images both in the studio and on location. This poses serious challenges to the user to assure that image and color quality can be maintained over time and possibly between a number of cameras. When numerous cameras are used in a given locale, the ability to seamlessly transition from one camera to another, one perspective to another, with no noticeable change in color quality is imperative. It is essential to understand the numerous elements that contribute to and effect television color reproduction. The review of these concepts will be brief and readers are encouraged to consult additional texts in this area for more in-depth review.To obtain colorimetric calibration of a television camera, the measurement of a Color Reference Chart is appropriate and can provide a meaningful analysis of camera response as well as insight on the necessary means of adjustment to achieve desired effects. A similar type of Color Test Pattern can be useful in evaluating color reproduction of a complete television system. The parallel development of both a Color Reference Chart and Color Test Pattern, to facilitate the colorimetric calibration of color television cameras will be discussed. Both are currently under review by the Society of Motion Picture Television Engineers for adoption as U.S. television standards.In addition, a television test and measurement product implementation of such camera calibration technology will also be reviewed.
