1. CIS image capturing system based on FPGA;

  • Comprise the CIS transducer;

    It is characterized in that;

    described CIS image capturing system also comprise the AD acquisition module that is connected with CIS transducer output, with the two-way FPGA data processing module that is connected of AD acquisition module, with the two-way LVDS modular converter that is connected of FPGA data processing module and single chip control module, with the two-way cameralink interface that is connected of LVDS modular converter;

    FPGA provides the work schedule of CIS;

    The image of CIS output is gathered through AD and is converted digital signal to, carries out preliminary treatment by FPGA, and stores in the internal RAM;

    According to the cameralink data format, export data to the cameralink interface with the form of difference through the LVDS chip.
