Real-time image processing system based on FPGA for electronic endoscope

Medical electronic endoscope is the outcome of combining traditional endoscope technology with modern computer technology and microelectronic technology. Because of the limit of space, the endoscope adopts a kind of compact full frame CCD whose output image pattern is different from the pattern of PAL monitor. To improve image quality and display 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
