According to one embodiment, a server device includes a receiver, an acquisition unit, a difference extracting unit, an estimation unit, a determination unit, a compression unit, and a transmitter. The receiver receives manipulation information from a client device. The acquisition unit acquires a display image on which the manipulation information is reflected. The difference extracting unit extracts a region where pixel information on an image transmitted to the client device is not matched with pixel information on the display image. The estimation unit estimates an elapsed time since the manipulation information is received until the display image is acquired. The determination unit determines image quality, for which a response time is a predetermined value or less, on the basis of the elapsed time. The compression unit generates a compression image in which the image in the region is compressed with the determined image quality. The transmitter transmits the compression image.
