Television picture centering control |
摘要 |
A control circuit is provided for centering a display on a cathode ray tube by manual adjustment. A reference signal is received corresponding to a fixed point on the display. A shift circuit provides a shifted synchronizing signal, having a shift that is variable, to place the fixed point at a desired location on the cathode ray tube. The shift may be either an advance or a delay of the signal.
