Television Line Structure Suppression
Francis T. Thompson · Journal of the SMPTE · 1957
Experiments indicate that television viewers select a viewing distance at which the line structure begins to disappear. If the line structure is destroyed, the preferred viewing distance is reduced to about 60%. Other advantages and the disadvantages of eliminating the line structure are discussed. Several methods of eliminating it are described. The results of an experimental comparison of television pictures with and without structure suppression are given. A photographic comparison is also given.
