摘　　要：随着嵌入式系统软、硬件的快速发展和通信带宽的拓展,网络图像传输将广泛应用于各领域。基于硬压缩的网络图像传输装置是以S3C4510B微处理器和MV3018芯片为核心的嵌入式网络图像传输系统。通过图像采集模块OV7660获取图像信号后,由MV3018完成图像的JPEG或MJPEG的压缩功能,实现图像的硬件编码,最后通过芯片RTL8201完成与互联网的接口。嵌入式处理器S3C4510B运行μClinux操作系统,实现了图像数据的采集、压缩和网络传输。实验证明,该系统可作为网络图像传输系统的平台。The image network transmission will be widely used in various areas because the software and hardware of the embedded system are developing rapidly, and communication bandwidth becomes wider and wider. The system introduced is an embedded image network transmission system with S3CAS10B microprocessor and MV3018 chip as the core. In the system,the image signals are acquired through image collection module OV7660,and then the function of JPEG or MJPEG image compression is accomplished by MV3018, thus the hardware encoding of images is implemented. Finally ,the interface to Internet is completed through RTL$201 chip. The acquisition, compression and network transmission of the image data are implemented by the embedded micro processor S3CA510B which is running μClinux operating system. The experiments show that the system can be used as a platform for image network transmission system.
