[求助]摄像机有关参数及功能的英文缩写...

[WDR Control]: If you turn on WDR, you can’t set [BLC Control]. Wide dynamic range: WDR is intended to provide clear images even under back light circumstances where intensity of illumination can vary excessively, namely when there are both very bright and very dark areas simultaneously in the field of view of the camera. WDR enables the capture and display of both bright and dark areas in the same frame, in a way that there are details in both areas, i.e. bright areas are not saturated, and dark areas are not too dark. If select BLC,there are 5 modes:WDR,AD_WDR,WDR+Contrast offset, AD_WDR+Contrast offset, Contrast offset If select BLC,then [BLC Control] is hidden.. 请问一下，这里的5种宽动态模式：WDR , AD_WDR , WDR+Contrast offset , AD_WDR+Contrast offset , Contrast offset 它们分别是什么的缩写，表示什么意思？
