[The hardware design of a portable gastrointestinal wireless endoscope image receiver].
The portable gastrointestinal wireless endoscope image receiver is developed and based on TMS320C6211 DSP. It can receive and demodulate the modulated signal which is transmitted from the camera-capsule, and then output the video signal. The synchronizing signals offered by SAA7114H are made best of and are used to design the time logic circuit. The fitful video signal can be collected under the control of the time logic circuit. The circuit can automatically get rid of useless blank data and only collect effective and good-quality video signals, and storage them in CF card. In addition, the image signal can be processed and compressed by DSP, and thus the data storage space and the data- analyzing time can be saved.
