Disclosed is an image service system using a functional film, which has an advertisement exposure space in a window, and selectively outputs an image in a bidirection or unidirection. To this end, the image service system comprises: a case mounted on a window; a first winding bar coupled to the case; a second winding bar coupled to the case to be rotated according to the movement of an elevation rope, and disposed between the first winding bar and the window; a functional film coupled to the first winding bar, and having an image displayed on both surfaces; a light blocking film coupled to the second winding bar; a beam projector for outputting the image onto the functional film; and a management terminal connected to the beam projector in a wired/wireless network to transmit image data to the beam projector. According to the present invention, since facilities such as the window or the like equipped in a building which has dense population, can be used as a billboard, the advertisement exposure space can be sufficiently secured. |
