摘要: Dynamic adjustment techniques for aligning video images in cathode ray tube (CRT) devices (12) are disclosed. A host computer (10) stores correction factor data and image graphics controller RAM (20). The processes transmits the data, representative of distortion characteristics, to CRT device during retrace time electron beam trace time. may be generated by a vision system, gain matrix table, interpolation engine or manual methods. Circuitry, within (12), separating from signal is disclosed along with methods apparatus used decode data. Data can also transferred monitor back over connector (16).
