An image processing device includes: an image sensor for acquiring a pixel value of each of a plurality pixels; and a controller for acquiring a pattern image including the pixel value of each of the plurality of pixels and an exposure value representing an exposure time, generating a plurality of super resolution images based on pixels having the same exposure value among the plurality of pixels included in the pattern image, generating a motion map, which represents a motion of an object based on a ratio of exposure values of pixels at a selected position among a plurality of pixels included in the plurality of super resolution images and a ratio of pixel values of the pixels at the selected position, and generating a target image according to a weighted sum of the plurality of super resolution images and the motion map.
