Discussion to Auto-iris Control Method Used in Televison Camera Lens
The paper introduces simply the principle of the traditional auto-iris control method used in television camera lens and analyses its problems in engineering. The author brings up three kinds of solving methods
atificial affacting
block control and moving block control. Their working principle and specialities are discussed in detail.
