Abstract

PURPOSE:To make possible the registration correction for independent four corners and to make correction with high accuracy, by selecting vertical and horizontal saw tooth wave signals and parabola waveform signal on a TV reproduced screen respectively and adding them with level adjustment. CONSTITUTION:Signals from horizontal drive HD and vertical drive input terminals 1, 2 are respectively applied to H and V fundamental wave signal generators 13, 14 and a SAW signal is produced from a saw tooth waveform SAW generator 3 of the generators 13, 14. This SAW signal produces the SAW signal more than right and left reference levels from comparators 4, 5, to output the H and V SAW signals from SAW output terminals 8, 9, 15 and 17. Further, H and V PARA signal are produced from a parabola waveform PARA generator 10 inputting the SAW signal and outputted from H and V PARA signal output terminals 11, 12 and 16, 18. Further, each level of H and V SAW and PARA signals is adjusted and added, allowing to correct the registration for independent four corners.
