| Abstract: | A image acquisition system based on high quality single -chip multi format video decoder ADV7441 and FPGA, and describe the hardware composition and work principle of the system. This system is used for video output automation testing system, DUT output image signal , converted to digital signal by the ADV7441, controlled by FPGA, recording each pixel value, and compare with the sample values which are saved in other Serial Flash, Using MCU return the result to program. Finally, Through the testing to verify Feasibility in Industrial testing system. |
