A novel wireless capsule endoscope with JPEG compression engine

To improve the quality of images collected by the wireless capsule endoscope (WCE) and to decrease the system energy consumption, we proposed a novel design of WCE. This WCE system integrates a CMOS sensor with an optional JPEG compression engine, a low power consumption high-performance micro-controller and an ultra low power RF transceiver in a small capsule (less than 10 mm × 25 mm). Experiment results show that this WCE system can collect much more images with its JPEG compression engine and the image quality can also be improved. In this paper, we will introduce the architecture of the WCE system. The experiment results and the performances of the system will also be presented.
