To provide a display control device capable of presenting information for reducing the possibility that a piston of a hydraulic cylinder may hit a stroke end, to an operator.SOLUTION: A pick-up image acquisition unit acquires a pick-up image including an image of a working unit from a camera provided at a work machine. A blade edge image generation unit generates an image of the blade edge obtained by projecting a blade edge of the working unit vertically to the projection surface. A display image generation unit generates display images in which the pick-up image, the image of the blade edge, and a figure of a reference range obtained by projecting a reachable range of the blade edge vertically to the projection surface are overlapped. A display control unit outputs display signals for displaying the display image.SELECTED DRAWING: Figure 4 【課題】油圧シリンダのピストンがストロークエンドに当たる可能性を低減するための情報をオペレータに提示する。【解決手段】撮像画像取得部は、作業機械に設けられたカメラから、作業機が写る撮像画像を取得する。刃先影生成部は、作業機の刃先を投影面に鉛直方向に向けて投影した刃先影を生成する。表示画像生成部は、撮像画像と、刃先影と、刃先の到達可能な範囲を投影面に鉛直方向に向けて投影した基準範囲図形とを重畳した表示画像を生成する。表示制御部は、表示画像を表示するための表示信号を出力する。【選択図】図４
