The image processing device includes an image signal processor for processing a raw image received from a camera and a memory for storing a previous frame of the raw image and an intermediate image generated by the processing, wherein the image signal processor estimates an initial global motion vector between the previous frame and a current frame, receives focus region information in the raw image, divides the raw image into a foreground (FG) region and a background (BG) region based on the focus region information, generates a final global motion vector by divisionally updating the initial global motion vector based on the FG region and the BG region, performs motion compensation by applying the final global motion vector to the previous frame, and outputs a final image by blending the motion-compensated previous frame with the current frame.
