摘要
针对视频延长设备在工程现场装配调节的不便,提出了一种视频延长信号的自动校色方法。通过颜色传感器探头在标定模式与校正模式下的交替工作,与接收器、显示器形成闭环反馈回路,结合时间最优PID算法实现红绿蓝等视频参数的自动调节,使视频信号在非延长状态和延长后达到画面色彩的一致。
An automatic color correction method is provided to solve the inconvenienee of video extension eqipment＇s adjustment on site. The color sensor probe works in the calibration mode and calibration mode alternately, and the receiver, the display formed a closed feedback loop. It realize automatic adjustment of the video parameters with PID algorithm for time optimal. It makes the color same in extension and non-extension.
