A study of explicit greytone perception on TV video monitors.
46 persons have been tested in their ability to resolve grey tones in quantitatively callibrated transparencies. The transparencies were designed as phantoms matched in lightness and dynamics to TV monitors. The results show that on average not more than 9 grey tones can be counted in such phantoms and that dark gaps between the fields decrease the confidence of viewers.
