PURPOSE:To connect extracted elements without spoiling the original shape of a moving body and precisely extract the moving body by connecting pixels by turning on OFF-pixels between a specific ON pixel and the ON pixel between which the largest gap is left and then connecting the pixels by repeating connections between pixels. CONSTITUTION:Image data are binarized by an element extracting processing means 20 and elements are extracted as an area composed of ON-pixels. The elements are, for example, elements 6 and 7 which are originally connected to constitute one closed area or an element 9 which has a small inlet-shaped part or not inlet-shaped part. The extracted elements are connected by a nearby element connection processing means 21. In this case, ON-pixel elements B and C within a circle which centers on the specific ON-pixels among the extracted elements and has a radius as long as several pixels are extracted. Then, when there are OFF-pixels between the pixel A and pixels B and C, the pixels between the pixel A and pixel B having the largest gap are all turned on. Thus, the pixels A and B are connected. |
