description The invention provides an audio and video image intelligent control system based on an FPGA technology, and is used for solving the technical problems of poor color of digital video pictures outputted by traditional audio and video images and unsmooth switching of multiple paths of video pictures. The system comprises an upper computer, a microcontroller, an FPGA video superposition processor and a video acquisition module. The upper computer is connected with the microcontroller through a serial port, and the microcontroller is respectively connected with the video acquisition module and the FPGA video superposition processor through an I2C bus; the video acquisition module acquires multiple paths of video input signals and outputs digital video signals to the FPGA video superposition processor through quantization coding, and superposed video signals are outputted after the digital video signals are processed by the FPGA video superposition processor. According to the system, the linear space change edge de
