AUTOMATIC DISPLAY VIDEO POSITIONING AND SCALING SYSTEM

摘要

An apparatus and method of automatically digitizing analog video and stroke with size and positioning information. This isaccomplished using signal characteristics of the deflection waveforms and video signals together with the video synchronization andblanking timing. This allows analog real time positioning and scaling by synchronizing the video data and deflection information. The deflectioninformation in the form of signals either or both horizontal or X axis and vertical or Y axis characteristics such as amplitude, peak or peaktopeak, and zero crossing, can be used to determine the size or scaling for each axis independently.
