The graphic system design in color image capturing system using the USB interface

The graphic system design has become one of the most generally design program due to its many advantages, including, easy reading, easy programming and friendly implement. Thus, it is widely used for research or other applications. In this paper, we implement a color image capturing system using the USB 2.0 interface and verify its performance in a PC environment. The system circuits can capturing the image data and transfer to the PC through the USB interface. We also test the USB speed of data rate for graphic system design program. The max data rate is 6.5 MB/s. That speed is also good enough for our applications.
