To meet the requirement of the especial sequence IR camera signal being captured by the general CameraLink imaging acquisition card

the sequence adjustment and interface transforming system based on FPGA was designed. The SignaTap tool was applied to measure the detailed sequence of the IR camera output and based on which the sequence adjustment system was designed according to the sequence requirement of the imaging acquisition card. The FIFO module in FPGA was applied to realize the pixel clock modification and the data saving and taking. The Verilog programming was applied to realize the pick-up of the valid signal

the cut-off of the invalid signal and the modification of the line valid and frame valid signal. The camera especial sequence adjustment system adjusted the especial sequence to the sequence that can be identified by the common CameraLink imaging acquisition card.The experiment shows that the processed image signal can be captured by the imaging acquisition card and the displayed image is correct and stable.
