Screen auto-alignment system

摘要

An auto-alignment system and a method for adjusting a picture image relative to a monitor screen. Video signals are detected by a video detection circuit detects and sent to a micro-controller. The micro-controller performs a computation of the received video signal, produces a set of data including a horizontal size, a horizontal phase, a vertical size and a vertical phase and sends the data to a deflection controller. The deflection controller adjusts position and size of the picture image relative to the monitor screen.
