Abstract

PURPOSE: To increase the faithful color reproduction by giving the control to secure the equiphase for the division signal to be compared with the index signal in terms of the phase and thus correcting the phase shift of the index signal along with the accurate color switching secured.
CONSTITUTION: Index fluorescent substance stripe I is formed to picture tube 10 with n-fold pitch of a pair of color fluorescent substance stripe. And signal SI sent from index signal detector 20 is supplied to PLL40 to form the pulse of 3n-fold as much as signal SI, and this pulse is divided 50 to form pulses PR, PG and PB each gating each primary color. Thus each primary color is supplied to picture tube in sequence and synchronously. Then PLL40 forms 42 gate pulse PN of the equal repetitive frequency as signal SI at the position of stripe I and based on the output of VCO41, and the signal supplied to tube 10 is detected 45 by pulse PN. This detection signal undergoes phase comparison 43 with signal SI, and this comparison output controls VCO41.
