摘要
医用电子内窥镜是传统内窥镜技术与现代计算机技术、微电子技术等高新技术的不断发展和融合的产物。电子内窥镜由于体积的限制采用一种超小型全帧面阵CCD ,其输出的图像格式与所采用的PAL制的监视器的格式不一致 ,同时为了改善图像质量和显示效果 ,系统采用现场可编程门阵列 (FPGA)实现了实时的图像处理。这种实时图像处理系统保证了图像的正确显示 ,并通过插值放大和增强处理改善图像质量 ,通过数字视频特技改善显示效果 ,提高诊断的准确率。
Medical electronic endoscope is the outcome of combining traditional endoscope technology with modern computer technology and micro_electronic technology.Because of the limit of its space endoscope adopts a kind of compact full frame CCD whose output image pattern is different from the pattern of PAL monitor.And to improve image quality and displaying effect the system implements real_time image processing with field programmable gate array(FPGA). The image pattern transformation ensures the correct display of the CCD output image.With the function of image interpolation zooming,image enhancement and digital video technology,image quality and the accuracy rate of diagnosis are improved
