Abstract
A plurality of images captured by a plurality of cameras respectively to create a plurality of upper viewpoint images. Display images are extracted from the upper viewpoint images, and the extracted display images are synthesized to create an overhead image or bird's eye view image of surroundings, which has an image corresponding to an operating machine at a center of the bird's eye view image. When extracting each of the display images, a region of the display image extracted from the upper viewpoint image is expanded beyond the size of a standard extraction region on the basis of the set height of a mating face. Each of the extracted display images is adjusted to the size of the standard extraction region, and synthesized. Thus, any three-dimensional object (obstacle) present near the boundary between display images constituting the bird's eye view image is displayed.
