Abstract :
The CCD (Charge-coupled Device) image sensor with its high resolution is capable of providing high definition image. However, transmission requires high bandwidth, which makes it very difficult to process and transmit in a long distance. The purpose of this paper is to propose a new method to process and transmit CCD image, which can guarantee a low-bandwidth and long-distance data transmission. The innovation is that the transmission content of CCD image data can be flexibly selected and compressed firstly, which will reduce the transmission data. Then it is processed on the base of communication protocol so that it can be fit for wireless transmission. At last, it is transformed into wireless signal and transmitted using 3G technology. As a result, the paper presents a wireless transmission scheme with the rate of 1.5Mbps for CCD image.
