An object image extraction unit (110) extracts, from a photographed image of ahead of a vehicle, an extracted object image matching an extraction condition among a plurality of object images. A display allocation area specifying unit (130) specifies in the photographed image, an area that does not overlap any extracted object image and that is in contact with any extracted object image, as a display allocation area of guidance information, and identifies an adjacent extracted object image that is in contact with the display allocation area and a tangent of the adjacent extracted object image to the display allocation area. An object space coordinate calculation unit (140) calculates a three-dimensional space coordinate of an object of the adjacent extracted object image, as an object space coordinate. A tangent space coordinate calculation unit (160) calculates, based on the object space coordinate, a three-dimensional space coordinate of the tangent on the assumption that the tangent exists in a three-dimensional space, as the tangent space coordinate. A display area determination unit (170) determines a display area of the guidance information on a windshield, based on the tangent space coordinate and three-dimensional space coordinates of the eye position of a driver and the position of the windshield.
