Zusammenfassung:The invention discloses a video parameter display system for adjusting user selection area comprising a level detector for detecting a line mode contained in a plurality of picture patterns for representing the complete graph, a mode receiver connected to the level detector for receiving the detected modes. Besides, the display system also includes a pixel counter and a pattern analyzer. 公布了一种用于调节用户选择区域的视频参数的显示系统。该显示系统包括:电平检测器,用于检测代表所显示的一个完整图像的多个图像行中一个所包含的行模式;以及模式接收器,连接于电平检测器,用于接收检测到的模式,其中检测到的模式包括位置标志,其尾部与用户选择区域的垂直边垂直对齐。另外,该显示系统还包括像素计数器,与模式接收器相连接,用于测量标志尾部相对于一个参考点的水平位置集合;模式分析器,其基于标志尾部位置,计算视频控制区域的垂直边的水平位置集合;以及视频前置放大器,用于调节视频控制区域的至少一个视频参数。
