  • Publication number: 20120246224
    Abstract: 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.

  • Patent number: 7974494
    Abstract: Image control involves receiving source images defined with respect to respective source coordinate systems from source image generators also respectively associated with source IDs. The source images are composed to generate a composite image defined with respect to a composed coordinate system, and the composed image is sent to a viewer which displays the composed image and outputs an HID signal which indicates information defined with respect to the composed coordinate system. A layout manager stores source IDs respectively associated with layout information including position and size of at least one of the source images. An image composer composes the source images according to the layout information. An analyzer analyzes the HID signal for editing layout information stored in the layout manager, and determines a source ID a source image according to the layout information.

  • Publication number: 20110157606
    Abstract: There are provided an image printing system and an image processing method which can perform printing control for a unit pixel without losing a positional relationship between a dot arrangement pattern and a mask pattern even when index processing and mask processing are executed independently from each other. For this purpose, an index start position command (901) is transmitted, and the mask pattern is arranged such that the top of the mask pattern matches a top raster of a received index processing start position when the mask processing is executed. Thereby, it becomes possible to securely execute the printing control for a unit pixel without losing the positional relationship between the dot arrangement pattern and the mask pattern which are generated in association with each other.
