Abstract

PURPOSE:To obtain various special effects, by shifting the phase of the color burst signal and luminance signal to an arbitrary desired value, and by transmitting the video signal of different lightness and hue in place of original color video signal. CONSTITUTION:In case of the inverting mode of color TV camera, the selector switches 14, 27 are respectively connected to the contacts 14b, 27b, the burst flag from the burst flag generator 13 is fed to the inversion circuit 15 with the change- over of the switch 14, and after the polarity inversion, it is fed to the mixer 12. Further, it is mixed with the chroma signal R-Y from the wave-shaping amplifier 11 obtained the same signal processing as the normal mode at the mixer 12 to invert the polarity of the burst flag. The output synthesis signal of the mixer 12 is fed to the balancing modulator 17 for balancing modulation, and from the burst flag, it is picked up as the time series synthesis signal for the color burst signal present for the period and different in the phase, and the color burst signal is shifted in the same phase as the B-Y axis, allowing to obtain the video signal of different lightness and hue.
