    The role of an iris The P-Iris system involves a new approach to looking at the role of an iris and is the result of a joint development effort between Axis Communications of Sweden and the Japanese lens manufacturer Kowa.

    How P-Iris works P-Iris is a new type of iris control that is both automatic and precise. Unlike a DC-iris lens, the main task of the P-Iris control is not to continuously adjust the flow of light through the lens. The primary objective of P-Iris is to improve image quality by enabling the optimal iris position to be set so that the central and best-performing part of the lens is used most of the time.

    Although the P-Iris control is initially available only in Axis network cameras, the technique has the potential of becoming a new industry standard as Axis and Kowa have decided to make P-Iris accessible to the whole industry.
