Abstract
A viewfinder control unit includes a liquid crystal viewfinder with a hood; a sensor for picking up the face of a cameraman; a pan motor for horizontally rotating the viewfinder; and a tilt motor for varying the angle the viewfinder makes with a horizontal plane to provide the cameraman with an optimum view angle. The viewfinder undergoes tracking control such that it is always trained on the face of a cameraman in response to the panning (left or right swing of a lens) and the tilting (up or down swing of the lens) of the television camera.
