基于FPGA的电子内窥镜CCD彩色图像采集与显示系统

The CCD Color Image Acquisition and Displaying System of Electronic Endoscope Based on FPGA

本文介绍了电子内窥镜 CCD图像采集和显示系统的研究与实现 ,并主要论述了以现场可编程门阵列 (FPGA)为系统控制核心的 CCD图像采集和视频显示缓存管理及窗口控制 ,以及基于锁相原理的系统时钟的生成 。

This paper introduces the study and implementation of CCD image acquisition and displaying system of electronic endoscope. As the field programmable gate array (FPGA) being the core of this system, the paper describes the CCD image acquisition、displaying buffer management and window control. Based on the principle of phase-locked loop, the generation of system clock including the circuit of the synchronization signals and high-frequency master clock is also described in detail.
