The invention discloses a dynamic image processing system and an image processing method, the dynamic image processing system comprises an image sensor and an FPGA connected with each other, the imagesensor comprises a register module and an image generation module, the image generation module is used for generating an image, and M register modes are stored in the register module; the FPGA comprises a clock module, a configuration module and a receiving and processing module, the receiving and processing module is used for receiving the image sent by the image generation module and processingthe image, M clock modes are stored in the clock module, and M configuration modes are stored in the configuration module, wherein the M register modes, the M clock modes and the M configuration modes are in one-to-one correspondence. The invention provides a dynamic image processing system and an image processing method. The FPGA and the image sensor are dynamically configured, and the transmission frame rate of the image sensor and the processing rate of the FPGA are sequentially changed in an extremely short time under the action of the configuration module in the FPGA, so that the processing capacity of the FPGA for the image sensor is improved.
