| Abstract: | With the improvement of geometric and radiant resolution of CCD camera,data must be transferred with higher rate and more channels,and interface between CCD camera and frame grabber with better performance was required.In this paper,a high speed digital image transmission method based on P/S or S/P conversion chip was proposed.The proposed method could increase the data transmission rate and decrease the amount of the cable,which would make the camera smaller and lighter. |
