description A motion detection method for detecting a motion region of an image of a specific subject on a screen to be monitored, including steps (a) to (c). In step (a), information on a reference height and a reference width of an image of a specific subject is obtained for each pixel of the screen to be monitored. In step (b), when a motion area is detected on the screen to be monitored, it is determined whether or not the specific subject is within the motion area according to information on the reference height and reference width of the image of the specific subject. In step (c), if it is determined that the specific subject is within the motion area, a detected motion area is displayed on the screen to be monitored. Accordingly, the number of motion detection errors may be reduced. 감시 대상 화면상에서 특정 대상의 영상의 움직임 영역을 검출하는 움직임 검출 방법으로서, 단계들 (a) 내지 (c)를 포함한다. 단계 (a)에서는, 감시 대상 화면의 각각의 화소에 대하여 특정 대상의 영상의 기준 높이와 기준 폭의 정보가 구해진다. 단계 (b)에서는, 감시 대상 화면상에서 움직임 영역이 검출되면, 특정 대상의 영상의 기준 높이와 기준 폭의 정보에 따라 상기 움직임 영역 내에 상기 특정 대상이 있는지의 여부가 판단된다. 단계 (c)에서는, 상기 움직임 영역 내에 상기 특정 대상이 있다고 판단되면, 검출된 움직임 영역이 감시 대상 화면상에 표시된다.
