With the progress of CMOS image sensor technology, CMOS image sensor is getting faster development and application. CMOS image sensor has many advantages, such as low power consumption, small size and low price. It is widely used in the field of image sensor. This paper mainly introduces a design scheme of CMOS image sensor acquisition system based on FPGA. In the design, the CMOS image sensor transmits the collected image data to the FPGA after photoelectric conversion and analog-to-digital conversion. After format conversion and buffer processing, the image data is displayed on the display through VGA interface. The whole design has the advantages of simple structure, reliable transmission and good test results.
