An image projection system comprising: an image processing unit configured to split a static image into a plurality of split images on the basis of positions and sizes of a plurality of surfaces included in an area; and a signage control unit configured to control said image projection system to project the split images respectively onto projection surfaces corresponding to the plurality of surfaces, using projection apparatuses corresponding to the plurality of surfaces; wherein the image processing unit comprises a first splitting unit configured to split the static image into first split images on the basis of the positions and the sizes of the plurality of surfaces included the area, wherein the first split images are horizontally reversed images, characterized in that the image processing unit further comprises: a decoding unit configured to extract the static image from a decoded dynamic image; a second splitting unit configured to further split each of the first split images corresponding to one of the plurality of surfaces, on the basis of a number of projection apparatuses installed at the one of the plurality of surfaces, so as to generate second split images, the number of second split images for the one of the plurality of surfaces corresponding to the number of projection apparatuses installed at the one of the plurality of surfaces; an encoding unit configured to encode, for each projection apparatus, the second split image corresponding to the projection apparatus into a projection dynamic image; and a transmission unit configured to transmit the projection dynamic images to their corresponding projection apparatuses; the system being also characterized in that the signage control unit is further configured to control said image projection system to project the projection dynamic images onto their corresponding projection surfaces by transmitting instructions to the projection apparatuses corresponding to the one of the plurality of surfaces at a given time, said instructions causing each projection apparatus to project the corresponding projection dynamic image. an image processing unit configured to split a static image into a plurality of split images on the basis of positions and sizes of a plurality of surfaces included in an area;
