We presented a wireless endoscope system developed on the embedded Linux platform. This wireless endoscope system consists of three parts: the endoscope capsule,the portable equipment and the image workstation,which make this system wireless and portable. Hardware design of this system and software design of the portable equipment are described. In clinical use,patients swallow the endoscope capsule for gastrointestinal inspection. The portable equipment receives images of gastrointestinal tract via the radio frequency module while it sets and reads back parameters of the capsule via the low frequency module. Acquired image data can be saved as a FAT32 format file in an universal serial bus disk. Images can be processed and reviewed at an Microsoft Windows PC workstation in the next stage. The image acquired by this wireless endoscope system is quite effective with clear details of gastrointestinal tract. However,the endoscope capsule was large,making it difficult to swallow. So the printed circuit board design of endoscope capsule needs to be improved.
