| Abstract: | Based on charge coupled device (CCD) and peripheral devices, a kind of image data acquisition system design was introduced. Coupled with vertical clock driver chip, Filed Programmable Gate Array (FPGA) drives the CCD sensor. In addition, FPGA processes the incoming image data and controls the acquisition, A/D transition, buffer and 1394 data packaging of image data. The demand of long distance and high speed data transfer of image acquisition was met. The continuous image data acquisition and processing were realized. The CCD image data acquisition system has a broad perspective of applications. |
