Abstract
Based on an input image from an imaging device and a preset background image, a digitized image is generated for each frame. The digitized images are compared. Then, an increased region, a decreased region, and an overlap region, which are adjacent to each other, are extracted as a single integrated region. Region parameters, which are a region area, a sum of X-coordinates and a sum of Y-coordinates, are obtained for each of the extracted integrated region, the increased region and the decreased region. Based on the region parameters, a motion of the object displayed on the integrated region is obtained for each of the integrated regions.
