摘要
提出一种基于DSP的无线图像传输系统,该系统实现图像的采集、压缩、无线传输及显示。概述系统设计过程,并重点讨论DMA在图像采集和JPEG压缩过程中的应用。最终通过对系统图像传输质量和传输速度的测试证明:该系统有效和实用。该系统设计适用于低端低价位无线图像传输产品或消费电子类产品,特别适合于家庭和临时场所使用的低端无线监控系统。
An image compression wireless transmitting system based on DSP is realized in this paper.This system realizes image acquisition, compression, wireless transmission and display.The design procedure of the system is submitted and the use of DMA in image acquisition ,JPEG compression is discussed in this paper.The effectiveness and practicability of this system has been eventually proved by testing image quality and transmission speed.The system is suitable for low-end lowcost wireless video transmission products or consumable electronic products,and particularly is suited to been used as wireless monitoring system in families and temporary places.
