The Focusing View-Finder Problem in Television Camera
G. L. Beers · Journal of the Society of Motion Picture Engineers · 1943
The technical excellence of a television program may frequently depend upon the characteristics of the view-finder used in the television camera. Conditions peculiar to television make it desirable that television camera view-finders be of the focusing type. The requirements of an ideal view-finder of this type are discussed. During the past ten years a number of view-finder arrangements have been investigated in connection with the development of television cameras. Several of these are described and their relative merits indicated.
