| Nowadays, most digital camera is equipped with Camera Link standard interface. The Image Acquisition Board is used to capture the stand cameral signal from Camera Link by connecting the camera and the PC with PCI interface. In this thesis, a new portable technology for Camera Link signals and displays is introduced. It can be used to any kind of Camera Link to display the signal in theoretically.In the thesis, two solutions are figured out for the basic problem of digital video conversion:one is the choose of the position to interpolation, another is the method to get the value of the pixel. Meanwhile, by comparing the interpolation algorithms usually used in hardware real-time operation, the most appropriate algorithm for this article's requirement is concluded via experiments.The system algorithm is supported by the structure of signal-chip FPGA+SDRAM and use CMOS camera to complete the display on the LCD. |
