A virtual space configuration unit 23 detects, on the basis of depth information of an image of a real space around a user, a position of an object in the real space and arrange a virtual body at a position in a virtual space corresponding to the detected position of the object to configure information of the virtual space. An image generation unit 25 generates an image of the virtual space configured by the virtual space configuration unit 23. A depth comparison unit 22 compares the depth information of the image of the real space and depth information of the image of the virtual space to decide an unknown depth region. The image generation unit 25 displays information indicative of presence of an unknown object in the unknown depth region of the image of the virtual space.
