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。
A video signal processing method based on FPGA is proposed. After the video signal detection, control timing occurs, the display data expansion and image backward to achieve the correct real-time display of the input signal. Proven, a special 480 × 480 resolution timing video signal can be displayed in the 640 × 480 physical resolution on the LCD screen backward in the specified 480 × 480 pixel area. The design method is stable and reliable, has portability and great application value.
