Abstract: Determining a phase shift compensation for automatically centering an image by measuring a start time delay between a horizontal scan line signal and an active video signal, measuring an end time delay between the active video signal and the horizontal scan line signal, and computing a phase shift for a horizontal flyback signal using the start time delay and the end time delay. A system to center an image on a monitor includes a video processing circuit and a rasterizer. The video processing circuit receives a video signal and measures a start time delay and an end time delay between a horizontal scan line signal and an active video signal. The circuit generates a phase shift used to generate a horizontal flyback signal using the measured start time delay and the end time delay. The rasterizer receives the output of the video processing circuit to control a scanning element.

Abstract: A moiré adjustment circuit receives a horizontal synchronization signal having a horizontal scanning frequency and a moiré adjustment signal substantially proportional to a horizontal spatial offset of alternate display lines on the display to correct the moiré effect. The moiré adjustment circuit generates a horizontal position signal having a first frequency proportional to the horizontal scanning frequency and a position value substantially proportional to the moiré adjustment signal and the horizontal scanning frequency. A horizontal position control circuit, coupled to the moiré adjustment circuit, generates a horizontal reference signal having a second frequency substantially equal to the horizontal scanning frequency and a reference phase that is shifted from a synchronization phase of the horizontal synchronization signal substantially in proportion to the horizontal position signal.

Abstract: The present invention is a method and apparatus for selecting a capacitor value corresponding to a horizontal frequency in a video monitor. The technique determines the horizontal frequency and creates a limit on a default capacitor value which is obtained from the determined horizontal frequency. An updated value is compared with the limit to generate a comparison result. The capacitor value between the default capacitor value and the updated value is selected based on the comparison result.

Abstract: In a display monitor, a horizontal synchronization signal having a horizontal scanning frequency is received by a first circuit. A vertical synchronization signal having a vertical scanning frequency is received by a second circuit. A moire correction signal that is proportional to a horizontal resolution of the displayed image is generated by dividing the horizontal scanning frequency by the vertical scanning frequency.

The system comprises a video processing circuit that receives a first signal, and which generates a second signal that includes a video signal and a synchronization signal, which is provided to the cathode ray tube. The cathode ray tube generates a beam current corresponding to the second signal, where the beam current has a video signal portion and a synchronization signal portion. A storage element coupled between the video processing circuit and the cathode ray tube clamps the second signal at a first predetermined level, and stores an electrical charge corresponding to the video signal portion of the beam current during a first time interval.
