Abstract :
This paper presents a design method of infrared image display card using FPGA and ADV7123. Its main function includes pixel gray level conversion, image zoom in and PAL standard video signal generation. The design ideals, hardware architecture, FPGA logical modules, FPGA configuration, interconnection between display card and master board, and the PAL standard video signal generation method using ADV7123 are discussed in detail. The display card is mainly applied to the hardware debugging of infrared image system and effect observation of the infrared image processing algorithm. The actual using shows that the card can well meet the display requirement of the infrared image processing system.
