Abstract
In a television camera, the variable gain control is adjusted to provide a corresponding change in the camera output video signal level. The iris control simultaneously is changed to maintain the preset video signal level. This varies the iris setting and provides a corresponding change in the depth of focus to allow focussing on different objects in a scene.
