1. 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 image-capturing unit configured to capture a plurality of images of an object at a plurality of zoom factors which are required when displaying the display image a metadata creation unit configured to: (i) obtain metadata which associates the plurality of images captured by the image-capturing unit with one another and includes relative position information which indicates positional relationship between respective areas of the plurality of images based on capturing conditions and the zoom factors of the respective plurality of images, the metadata being used for determining an order and timing for switching the display image, and (ii) store the metadata with the plurality of images in a memory device; and a hierarchical data creation unit configured to create, as the image data, hierarchical data obtained by hierarchizing the plurality of images in an order according to the zoom factors included in the metadata, and by aligning the plurality of images in respective layers in the hierarchical data by using the relative position information included in the metadata.
