In order to precisely draw an interference range when displaying a situation around a slewing-type work machine using a bird's-eye-view image, the present invention is provided with: a plurality of cameras (13) installed in a hydraulic shovel (1) and used for photographing diagonally downward in respectively different directions; a viewpoint conversion unit (21) for performing coordinate conversion on the image data photographed by each of the cameras (13) so that each of the image data becomes a bird's-eye-view image looking down from above; a synthesized bird's-eye-view image generation unit (22) for generating a synthesized bird's-eye-view image (P) by disposing the bird's-eye-view images around an image depicting the hydraulic shovel (1); an interference range drawing unit (25) for drawing, on the synthesized bird's-eye-view image (P), an interference range in accordance with ground height, in which range the hydraulic shovel (1) interferes with a surrounding obstacle when the hydraulic shovel (1) is turned; a display image generation unit (26) for generating, as a display image, the synthesized bird's-eye-view image (P) on which the interference range was drawn; and a monitor (15) for displaying the display image.
