【摘要】 介绍了医用电子内窥镜畸变实时校正系统的功能与构成。为了实现畸变的实时校正,要求解码器对模拟信号解码与编码器对数字信号编码必须同步进行。FPGA作为视频控制中心,实现了协调解码器与编码器的同步控制。更多还原

【Abstract】 This paper introduces the function and components of real-time distortion correction system of medical electronic endoscope (MEE). In order to implement real-time correction of distortion, encoder must encode the digital signals synchronously when decoder begins to decode the analog signals. As the video control center, FPGA harmonizes the video sync control of decoder and encoder.更多还原
