| Abstract: | This paper presents an image acquisition system based on area CCD. The driving timing of the CCD image sensor ICX424AQ and the conversion timing of the AD converter AD9943 are analyzed, the driving circuit of imaging system is designed and implemented by FPGA. The research on the hardware implementation to obtain full-color images from the CCD image sensors covered by Bayer color filter array adopts bilinear interpolation algorithm. The image data is transmitted to LCD screen in real time. |
