1. An image processing device comprising:
an image sensor configured to acquire a pixel value for each of a plurality of pixels; and
a controller configured to:
acquire a pattern image including the pixel value of each of the plurality of pixels and an exposure value representing an exposure time for which the pixel value is acquired;
generate a plurality of super resolution images based on pixels having the same exposure value among the plurality of pixels included in the pattern image;
generate 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 among the plurality of pixels included in the plurality of super resolution images; and
generate a target image according to a weighted sum of the plurality of super resolution images and the motion map.
