摘要：
A region extraction device includes a segmentation unit for dividing an input image into a plurality of regions, a pixel number counting unit for determining the ratio of pixels of a predetermined value to all pixels of each of the plurality of regions, and a region extracting unit for extracting a region in which the ratio determined by the pixel number counting unit exceeds a first value. Among the plurality of regions into which the input image is divided, a region is extracted in which the ratio determined by the pixel number counting unit exceeds the first value, so that a specific region can be extracted accurately even if the values of pixels in the specific region to be extracted are scattered in a wide range.
