摘　　要：DSP是一种集成度高、运算速度快,具有特殊结构的微处理器。利用DSP设计的视频图像采集与处理系统具有小型化、低功耗、低成本、应用灵活等特点。本文基于ADSP-BF561,设计了一套对视频图像的采集、处理和实时显示的嵌入式视频图像处理系统,该系统利用DSP芯片BF561在图像处理中的优异性能,克服了传统的基于PC机和图像采集卡的图像处理系统体积大和扩展性差等缺点。在介绍系统的组成和基本原理的基础上,详细分析了该系统的图像采集处理过程,并通过Matlab仿真与该系统测试进行图像处理实验对比。实验表明,该系统具有良好的稳定性、实时性。DSP is a type of special structure microprocessor, it has characteristic of high integration, high speed. The video system based on DSP has the advantages of miniaturization, low-consumption, low-cost and flexible-used. A video acquisition, processing and display embedded system in time based on ADSP-BF561 is proposed in this paper. This system takes full advantage of the excellent performance of the chip BF561 in image processing. It gets over the shortcomings such as large bulk and poor scalability of the traditional PC-based data acquisition card. Based on the introduction of the system structure and basic principle, the image acquisition and processing procedure was analyzed, and simulation based on MATLAB is done, used for comparison with the test on DSP platform. The test showed that the system can work independently, had the value of stability and real-time, it can be applied to all kinds of real-time image processing.
