摘　　要：为了将Cameralink输出标准的数字相机直接输出在显示器上显示,对视频信号进行实时处理。国内已经研制出一种实时小型化系统可以实现信号的转换,但仅限于将Cameralink与VGA相同分辨率条件下进行转换显示,无法对高分辨率(1920×1080)图像进行直接显示。提出一种设计方法,可以将高分辨率的输入图像显示在低分辨率(1 280×720)的显示器上。设计系统采用Cyclone Ⅳ系列EP4CE55F23C6N的FPGA板进行验证,实现了图像实时缩放操作。In order to display digital camera with Cameralink output standard directly on the display,the video signal needs to be processed in real time.A real-time miniaturization system has been developed in China to realize signal conversion,but it is limited to the conversion and display of Cameralink and VGA at the same resolution,and it is impossible to directly display images with high-resolution of 1920×1080.A design approach which allows high-resolution input images to be displayed on displays with low-resolution of 1280×720 is presented.The design system is verified by the FPGA board of Cyclone IV series EP4CE55F23C6N and realizes the real-time scaling operation of the image.
