Abstract
PURPOSE: To perform invariably-accurate color regeneration by making a divider, operated invariably by a start index signal for the start of a horizontal scan, operate continuously in a horizontal scanning period.
CONSTITUTION: This unit consists of index system cathode-ray tube 1, cathode electrode terminal 2, grid electrode terminal 3, luminance-signal amplifier circuit 4, limited-voltage input terminal 5, voltage limiting circuit 6 which limits the black level of a luminance signal applied to circuit 4 corresponding to a voltage applied to terminal 5, gate circuit 7 which cuts off the luminance signal periodically, luminance-signal input terminal 8, and control pulse input terminal 9 for control pulses for gate circuit 7. Then, voltage detecting holding circuit 10 detects a voltage applied to terminal 5 when a voltage equivalent to a preset cathode current value is applied to terminal 3 so as to obtain an index signal of an irreducible required level at which the cathode current operated the driver while circuit 7 is OFF, and the circuit holds the detected voltage until circuit 7 is turned off next and applies it to terminal 5 at the same time.
