Abstract: Using large scale programmable logic array (FPGA) to replace the computer to achieve high-resolution image collection,processing and displaying has a certain practical significance.This system can solve the problem of slow image acquisition speed and low image quality to achieve the video signal acquisition,storage,controlling sensors,image enhancement and LCD display.Structure of the system hardware components is introduced in detail and the working principle of hardware is analyzed.FPGA is easy to erase with large scale logic.The results can be translated to the computer through the serial port and USB port,at the same time mass storage can be achieved on board.The system has the quality of high integration,wide application and flexible use.
