摘要
药丸内窥镜也可称为“可吞服的数码相机”,形似一粒大胶囊,医用价值很大,在其内部结构上,药丸内窥镜在多种总线接口的辅助下向微机传输图像,显示病灶,给诊断提供依据。以药丸内窥镜的主要器件CMOS图像传感器OV7648为例,分析了SCCB总线、USB总线及无线接口的数据结构和传输流程,介绍了利用上述总线接口技术研制药丸内窥镜,取得较好效果的概况。
Pill endoscope, also known as swallowable digital camera, is similar in shape to a big capsule, it is valuable in medical application. Pill endoscope transfers image data to PC with the help of muhibus and multi-interface, then depicts focus and offers basis for diagnoses . We have studied data structure and transfer flow of SCCB bus, USB bus and wireless interface for CMOS image sensor OV7648 produced by Omnivision Technologies which is the main part of pill endoscope. The design and well working of pill endoscope are introduced using technology of bus interface mentioned above.
