A Method of Testing the Color Separation Characteristics of Color Television Camera Equipment
A method of testing the color separation characteristics of television film cameras as well as other types of television pickup equipment is proposed. A special test target printed on standard color positive film is scanned by the television camera under test. The signals at the outputs of the usual red, green and blue amplifier channels of the camera, resulting from scanning three separate color wedges are compared with the signals obtained at the same outputs from scanning a neutral-density step wedge. Experiments demonstrating the validity of this method are described, and the results of the tests together with an evaluation of the accuracy obtained in this manner are presented.
