【Abstract】 The hardware circuit of real time distortion correction system of Medical Electronic Endoscope(MEE) is designed and implemented to improve the distortion image and reflect the pathological changes part. FPGA is used as the video processor, and bilinear interpolation module is designed using Verilog HDL. The hardware bilinear interpolation of MEE standard video is implemented. The system delays 40ms.The relative distortion before and after the correction is separately smaller than 20% and ±1%.更多还原
