1. An electronic album editing system, provided as a computing device comprising a memory and processor that is communicatively coupled to the memory, for editing an electronic album including a plurality of images, comprising: a first storage device for storing each of a plurality of images included in a first electronic album in a corresponding category among a first plurality of categories previously classified by a user of the first electronic album along with range information corresponding to each of the first plurality of categories and indicating a range of image information for images classified in each category; a second storage device for storing each of a plurality of images included in a second electronic album in a corresponding category among a second plurality of categories previously classified by a user of the second electronic album; a category selection device for selecting one category from the second plurality of categories of the images stored in the second storage device; a range acquiring device for acquiring the range of the image information corresponding to the one category from the image information of the image included in the one category; a category detection device for detecting a category corresponding to the range similar to the range acquired by the range acquiring device using the range information corresponding to each of the first plurality of categories previously stored in the first storage device; and an editing device for editing the second electronic album by storing in the second storage device at least a part of the image stored in the category classified in the category detected by the category detection device, wherein the image information includes an image-capturing point of the image included in the electronic album, the range acquiring device acquires an image-capturing area, as the range of the image information corresponding to the one category, defined by a polygon which includes the image-capturing points of all the images included in the one category and of which vertexes are selecting points selected from the image-capturing points of all the images, where each of the vertex angles is less than 180 degrees, and the category detection device detects the category corresponding to one range information among plural pieces of range information previously stored in the first storage device when the range indicated by the one range information is the only range at least partially overlapped with the range acquired by the range acquiring device.
