PROBLEM TO BE SOLVED: To reproduce the state of a face, to which a medium is attached, so that it is possible to understand an electronic document printed on the medium. SOLUTION: In a document server 30, a reception part 31 receives an imaged image obtained by imaging a whiteboard, to which a medium is attached or an image is projected, from a projection imaging device, a difference information generation part 33 generates a difference image by calculating a difference between imaged images before and after one meaningful operation, a document retrieval part 35 compares the layout of the difference image with the layout of an electronic document to specify the electronic document, which is printed on the medium or which is the original of an image projected, and to generate display information obtained by arranging an element object, in which a link to the electronic document is embedded, at a position corresponding to the position of the difference image in the imaged image on a screen object showing the whiteboard, and a transmission part 39 transmits the display information to a terminal device.
