Claim One:
1. An apparatus for detecting a motion, comprising: a receiving unit which receives an input image; an average calculating unit which calculates an average of pixels by accumulating brightness of the input image on a pixel basis; an updating unit which updates the average with an updated average obtained by averaging brightness of featured pixels, in corporation with the average calculating unit, the featured pixels having an absolute value of deviation between the brightness and the average exceeding a preset object reference value, and the featured pixels accumulated from a point of time when the absolute value is received, if the absolute value exceeds the object reference value for more than a preset reference time from the point of time, the updating unit updating the average as a step curve by disregarding the brightness of the featured pixels if the absolute value does not exceed the object reference value for more than the preset reference time from the point of time; and a determining unit which compares the absolute value with at least one of a preset background reference value and the object reference value for the pixels, determines the pixels as a background if the absolute value is smaller than the background reference value, determines the pixels as garbage to be disregarded if the absolute value is larger than the background reference value and smaller than the object reference value, and determines the pixels as a moving object if the pixels are the featured pixels.
