An image processing system which can execute various image processings in an operation process of a robot is provided. The image processing system includes: a robot for performing a predetermined operation on a workpiece; a photographing unit for photographing the workpiece; an acquisition unit for acquiring a position of the robot; a field programmable gate array (FPGA) for reconfiguring an internal circuit configuration; a storage unit for storing area information where circuit information for implementing predetermined image processing on an image obtained from the photographing unit as information for defining the circuit configuration of the FPGA is defined for each operation area of the robot; and a reconfiguration unit for reconfiguring the circuit configuration of the FPGA with the circuit information associated with the operation area based on that a position of the robot sequentially acquired by the acquisition unit belongs to one operation area defined in the area information.
