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.

Abstract: Plural cameras are installed for the swiveling structure to monitor the vicinity of a working machine having a working member that is connected to the swiveling structure which is rotatably mounted on a traveling structure. The view field of two adjacent cameras partially overlap one another. A view point convertor converts the view point of the camera images acquired by the respective cameras to upper view point images. A display image creator creates an overhead view image composed of an illustration of the working machine as a plane view, and the upper view point images are converted from the converting view point convertor disposed around the illustration. An image display device is configured to show the overhead view image in the form of a plane view at least within a working reach region of the working member which is performing work by operation of the working member.
