实时视频处理近年来发展迅速,大多数实时视频信号处理算法均建立在对视频流信息的统计基础上。基于FPGA设计了通用视频帧信息提取程序模块,可实现实时对视频流进行分辨率、亮度比、灰度直方等信息提取及在屏幕上显示( OSD)的功能。测试结果表明,视频帧信息提取准确,OSD信息实时更新,兼容性好,运行稳定。此设计需要消耗8 kbit的LE资源和150 kbit的存储资源。
實時視頻處理近年來髮展迅速,大多數實時視頻信號處理算法均建立在對視頻流信息的統計基礎上。基于FPGA設計瞭通用視頻幀信息提取程序模塊,可實現實時對視頻流進行分辨率、亮度比、灰度直方等信息提取及在屏幕上顯示( OSD)的功能。測試結果錶明,視頻幀信息提取準確,OSD信息實時更新,兼容性好,運行穩定。此設計需要消耗8 kbit的LE資源和150 kbit的存儲資源。

Real-time video processing develops rapidly in recent years. Mostreal-time video signal processing algorithms are based upon the statistical information of the video stream. The design of a universal video frame information detection program module based onFPGA is presented. Specifically, it can detect information such as resolution,brightness ratio and gray histogram,and then display them on the screen( OSD) . The results show that the detection of frame information is accurate and the OSD information updates real-timely. It also has good compatibility and runs stably. This design contains 8 kbit LE( Logic Element) resources and 150 kbit storage resources.
