| Abstract: | An industrial inspection camera was designed, based on the advantages of the CCD sensor IL-P3-B, such as high real time, high resolution and low noise. The structure of driving circuits based on FPGA was analyzed. The waveforms of timing-driven in the quartus II simulation and the actual measurement were presented. In addition, an algorithm of calibrating image based on FPGA was researched. Experiments indicates that the signals which are generated by driving circuits based on FPGA as the key circuit meet the requirements of CCD, and that the quality of image can be improved after calibration in FPGA. |
