A bird's-eye view image generating device comprising: an image data acquisition unit configured to acquire periphery image data obtained by photographing a periphery of a vehicle; an obstacle information acquisition unit configured to acquire positional information of obstacles detected in the periphery of the vehicle; a bird's-eye view image generation unit configured to generate a bird's-eye view image, in a case in which there are a plurality of the obstacles, obtained by combining periphery images acquired by the image data acquisition unit, the periphery images having been subjected to viewpoint conversion processing so that a virtual viewpoint is positioned at a position at which the virtual viewpoint is separated from a position right above the vehicle and so that the virtual viewpoint is positioned at a position that is determined based on each of respective extension lines from the vehicle center to the obstacles so that the vehicle and a plurality of obstacles are able to be overlooked, based on the positional information of the obstacles acquired by the obstacle information acquisition unit; and a display control unit configured to cause a display unit to display the bird's-eye view image generated by the bird's-eye view image generation unit, wherein the bird's-eye view image generation unit further generates a bird's-eye view image that has been subjected to viewpoint conversion processing so that the virtual viewpoint is positioned on a bisector of an angle between any two of the respective extension lines from the vehicle center to the obstacles to be overlooked, or positioned on a bisector of an angle between any two of the respective straight lines passing by the vehicle center, each orthogonal to the respective extension lines. an image data acquisition unit configured to acquire periphery image data obtained by photographing a periphery of a vehicle; an obstacle information acquisition unit configured to acquire positional information of obstacles detected in the periphery of the vehicle; a bird's-eye view image generation unit configured to generate a bird's-eye view image, in a case in which there are a plurality of the obstacles, obtained by combining periphery images acquired by the image data acquisition unit, the periphery images having been subjected to viewpoint conversion processing so that a virtual viewpoint is positioned at a position at which the virtual viewpoint is separated from a position right above the vehicle and so that the virtual viewpoint is positioned at a position that is determined based on each of respective extension lines from the vehicle center to the obstacles so that the vehicle and a plurality of obstacles are able to be overlooked, based on the positional information of the obstacles acquired by the obstacle information acquisition unit; and a display control unit configured to cause a display unit to display the bird's-eye view image generated by the bird's-eye view image generation unit, wherein the bird's-eye view image generation unit further generates a bird's-eye view image that has been subjected to viewpoint conversion processing so that the virtual viewpoint is positioned on a bisector of an angle between any two of the respective extension lines from the vehicle center to the obstacles to be overlooked, or positioned on a bisector of an angle between any two of the respective straight lines passing by the vehicle center, each orthogonal to the respective extension lines.
