摘要

介绍了一种新的多扫描显示器几何校正和偏转控制系统。通过引入虚位坐标的概念，利用DSP技术，使图像在垂直频率、垂直尺寸和垂直位置发生变化的情况下，其垂直几何校正波形始终是相同的。此外，偏转电路通过总线完全数字化控制。本系统轻松实现了微机控制的多扫描监控系统。>

DIGITAL GEOMETRY CORRECTION AND DEFLECTION CONTROL SYSTEM FOR MULTI-SCAN MONITORS

A new geometric correction and deflection control system for a multi-scan monitor is described. By introducing a concept of imaginary position coordinate and using a DSP technology, the vertical geometric correction waveform is always the same for a picture even if the vertical frequency, the vertical size and the vertical position is varied. Furthermore, the deflection circuits fully digitally controlled via a bus. This system easily realizes a microcomputer controlled multi-scan monitor system. >
