Abstract: Provided is an image generation device which detects an obstacle that is present in the surrounding space, on the basis of a captured image obtained by a stereo camera of a head-mounted display, and sets a boundary 72 of a play area in which a user wearing the head-mounted display is allowed to move. When a new obstacle is detected inside the play area, the image generation device generates tangent lines 82a and 82 from an observation point H on a floor surface to a contour 80 of the obstacle and uses the tangent lines and a portion which is a part of the contour 80 and which is between tangent points AB to set a new boundary 86 of the play area.
