LI Ruijie, ZENG Xiangzhong. Realization of real-time image scaling in Cameralink TO VGA converter[J]. 2021, 40(1): 101-103. DOI: 10.13873/J.1000-9787(2021)01-0101-03.
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 1 920 × 1 080.A design approach which allows high-resolution input images to be displayed on displays with low-resolution of 1 280 × 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.
