A Comparative Study Between External USB and MIPI CSI for Medical Imaging and a Device Driver Implementation for Endoscope Camera Using USB

As mobile processor technology is evolving, multitasking has become the matter of a one finger touch. But unfortunately, this technology has not been used on a larger scale in a medical field. So, goal of this paper is to develop an android OS based platform which can interface with various health monitoring devices and to make an entire platform user friendly as much as possible. Initially, a comparative study is established between the USB camera and mobile industry processor interface (MIPI) Camera Serial Interface (CSI) camera in terms of speed, CPU usage, memory usage and max resolution. Later, we implemented a device driver for an external camera i.e. endoscope camera which uses CMOS image sensors. Eragon 820 mobile processor is used for android system development. USB Camera native libraries are used in an android application reducing the development time. Finally, device driver results are demonstrated granting permission of video capturing using external camera.
