一种特殊分辨率视频信号的处理和显示方法
Study of Processing and Displaying for Video Signal with Special Resolution
摘要
提出了一种基于FPGA的视频信号处理方法。经过视频信号检测、控制时序发生、显示数据扩展和图像倒向实现了输入信号的正确实时显示。经验证, 特殊的480×480分辨率时序的视频信号, 可在640×480物理分辨率的液晶屏上倒向显示在指定的480×480像素区域。该设计方法稳定可靠, 具有可移植性, 应用价值较大。
Abstract
In order to rotate the video 180 degrees with resolution of 480×480 and display it on 480×480 pixels of LCD with resolution of 640×480, a video signal processing method based on FPGA was proposed. After detecting input video, generating timing signal, extending displayed data and rotating the image, the input video could be displayed on the LCD correctly. The design is verified to work stably and reliably with great flexibility and feasibility.
