Abstract: Color and color changes of the skin and other body tissues can reveal important medical diagnostic information. The relevant color effects are sometimes so small that they are at or below the threshold of the color discriminating power of the eye. In particular this applies to skin color changes due to peripheral blood-flow. A system for expanded display of small color differences employing color television techniques is described. In the case of color effects due to peripheral bloodflow, a sixfold expansion of skin color changes appears to be feasible, yielding great improvement of diagnostic procedures. Design considerations for the system are presented and experimental results are described.
