An image data creation support device for supporting creation of image data used by a display device in which data of a plurality of images that have been captured at a plurality of different zoom factors are interchangeably used as the data of an image to be displayed at a predetermined scale ratio when enlarging or reducing a display image, comprising: an input information acquisition unit configured to receive an input specifying a desired zoom factor for the image of an object from a user; a radio reception unit of a GPS (Global Positioning System) configured to identify the position of the image data creation support device; an image-capturing unit configured to capture a plurality of images for displaying, that include the object, at a plurality of zoom factors starting with the zoom factor specified by the user which is received by the input information acquisition unit; a metadata creation unit configured to acquire metadata which associates the plurality of images captured by the image-capturing unit (210,212) with one another and includes the zoom factors of the respective images that determine an order and timing for the switching at the time of display, add the metadata to the image data, and then store the metadata in a memory device, wherein the metadata creation unit further acquires, as metadata, relative position information of each of the images with respect to a reference image with the smallest zoom factor based at least on the zoom factor and the position of the image data creation support device measured by the radio reception unit at the time of each image capturing by the image-capturing unit; and a hierarchical data creation unit for creating, as the image data, hierarchical data obtained by hierarchizing the plurality of images in the order of zoom factors, then analyzing the images, extracting respective feature points of an object that is the same in the images, and aligning the images in respective layers in the hierarchical data so that the respective positions of the feature points have correspondence when features in the images in respective layers have a size that is the same by enlarging or reducing, wherein the hierarchical data creation unit performs alignment for first stage alignment based on the relative position information and second stage alignment based on the respective positions of the feature points. an input information acquisition unit configured to receive an input specifying a desired zoom factor for the image of an object from a user; a radio reception unit of a GPS (Global Positioning System) configured to identify the position of the image data creation support device; an image-capturing unit configured to capture a plurality of images for displaying, that include the object, at a plurality of zoom factors starting with the zoom factor specified by the user which is received by the input information acquisition unit; a metadata creation unit configured to acquire metadata which associates the plurality of images captured by the image-capturing unit (210,212) with one another and includes the zoom factors of the respective images that determine an order and timing for the switching at the time of display, add the metadata to the image data, and then store the metadata in a memory device, wherein the metadata creation unit further acquires, as metadata, relative position information of each of the images with respect to a reference image with the smallest zoom factor based at least on the zoom factor and the position of the image data creation support device measured by the radio reception unit at the time of each image capturing by the image-capturing unit; and a hierarchical data creation unit for creating, as the image data, hierarchical data obtained by hierarchizing the plurality of images in the order of zoom factors, then analyzing the images, extracting respective feature points of an object that is the same in the images, and aligning the images in respective layers in the hierarchical data so that the respective positions of the feature points have correspondence when features in the images in respective layers have a size that is the same by enlarging or reducing, wherein the hierarchical data creation unit performs alignment for first stage alignment based on the relative position information and second stage alignment based on the respective positions of the feature points.
