ABSTRACT:
An output from a D.C. power source is supplied to a flashlamp through a high speed switching circuit. A current detection circuit detects a current from the high speed switching circuit and a voltage detection circuit detects a voltage applied to the flashlamp. A multiplication circuit multiplies the detected current and voltage to compute a product value. The high speed switching circuit is controlled so that the product value becomes equal to a predetermined value or an amplitude level of a pulse shape control signal inputted from the outside.
