Upon change of a zoom level of a current image not containing position information to a specified value on a user terminal, the calculation unit calculates a display range of an object represented by the current image after change in zoom level. The specifying unit refers to data of a different image of the object and specifies a part of the different image indicated by the display range calculated by the calculation unit. The different image has a different resolution from the current image. The generation unit generates a next image representing the part specified by the specifying unit using the data of the different image. The transmitting unit transmits the next image to the user terminal for switching from the current image to the next image.
