1. A system for detecting a motion, comprising: a parallel image generator configured to generate, in parallel, multi-resolution images, the generated multi-resolution images having at least two or more resolution levels; a characteristic dot extractor configured to extract a characteristic dot from at least one of the generated multi-resolution images; and a motion vector detector configured to detect a motion vector from a low-resolution image based on the extracted characteristic dot, and further configured to extend the detected motion vector of the low-resolution image to a high-resolution motion vector based on a result of the detection, wherein the characteristic dot extractor is further configured to generate a characteristic dot pixel from an image of a generated multi-resolution image having an intermediate resolution level, and wherein the characteristic dot extractor is further configured to divide at least one of the generated multi-resolution images into a plurality of square areas which do not overlap with each other, and configured to generate characteristic dot pixels of the square areas, the characteristic dot being determined based on the characteristic dot pixels.
