Abstract

PURPOSE: To correct a difference in hue by making it possible to generate an index signal matching with distortion on a scanning output surface.
CONSTITUTION: An oscillation output phase-locked by control pulse PA is phase- compared with a chrominance signal by phase comparator circuit 23 and the output of a comparison with control pulse PB is gated by gate circuit 24 and integrated by filter 25, whose output is supplied as control voltage Vϕ to variable oscillator 20. Gate pulse HDB is delayed by time 7B by delay circuit 26 to obtain pulse HDA. Since control pulse PB baries in phase with distortion on scanning output surface P, an oscillation output corresponding to the distortion on scanning output surface P can be generated through frequency control basing upon pulse PB.
