An information providing device can efficiently search for image data which includes an image of an object matching a user's preference, or can efficiently recommend information related to an image-capturing spot matching the user's preference. The information providing device receives three-dimensional arrangement information which indicates an arrangement of an object in three-dimensional space, and line-of-sight information for specifying a point-of-view position and a line-of-sight direction in the three-dimensional space, from a terminal device, generates two-dimensional arrangement information which indicates, in a two-dimensional plane, an arrangement of the object projected on the two-dimensional plane based on the received three-dimensional arrangement information and line-of-sight information, and compares arrangement information stored in a memory means that stores image data and the arrangement information which indicates, in an image, an arrangement of the object included in the image indicated by the image data, and the generated two-dimensional arrangement information, and searches for the image data based on a result of the comparison.
