Abstract : With the increased use of aerial color photography in remote sensing, it is necessary to consider color as a critical parameter for image electronic scanning systems. The purpose of the experiment was to determine if a black and white television system can be used to differentiate and identify colors from the various signal levels which the camera generates to produce graytones in television imagery. The experiments covered a variety of color samples: ICSS/NBS Color Chips, photo transparencies, photo prints, colored paper, and films. The color standard adopted for this study was the selected ICSS/NBS Color Chips. A high resolution TV camera, a waveform analyzer and a TV monitor were the instruments used in the experiment. The results showed that the system can discriminate most color changes in a geographic distribution. Some limitations result from the fact that more than one color value may generate the same signal level. The system can pick up and quantify density values which have interpretive significance, but complete color identification is beyond the capability of the system. (Author)
