  • Patent number: 9779277
    Abstract: A biometric authentication device has a structure member which is wearable to a user, and a biological information acquisition unit that acquires biological information of the user, and a biometric authentication unit that performs authentication of the user. The biological information acquisition unit is provided in a position where a finger of the user in contact when the structure member is worn/removed to/from the user, acquires first biological information with the finger of the user in contact with the biological information acquisition unit and second biological information which is at least one of a finger direction and action data, the finger direction is a direction of the finger in contact with the biological information acquisition unit and the action data is a data corresponding to spatial movement of the biometric authentication device when the structure member is worn/removed to/from the user.

  • Patent number: 9036056
    Abstract: In an image communication system of the present invention, the transmission and reception of images are performed between a mobile phone, which combines a base image (character) with an accessory image and displays the composite image, and a server device via a communication network. When an image of a subject is captured by an imaging section, the mobile phone recognizes the subject in the captured image as an image for distinguishing a character. Subsequently, the server device generates an accessory image based on the recognized distinguishing image. Then, the mobile phone combines the generated accessory image with the base image (character), and displays the composite image.

  • Patent number: 8918450
    Abstract: The present drawing data stored in the present drawing data storage unit is compared with the preceding drawing data stored in the preceding drawing data storage unit for each of the drawing areas divided by the area dividing unit, thereby determining whether there is a change in the preceding drawing data for each of the drawing areas in the present drawing data. Then, control is performed to transmit to the client apparatus the drawing data in a drawing area determined to have a change by the comparison decision unit, except for a drawing area of the present drawing data determined to have no change by the comparison decision unit. Consequently, it is possible to remarkably reduce the amount of data transferred to the client apparatus as a result of a change in the drawing and therefore transfer the drawing data at high speed.

  • Patent number: 8004532
    Abstract: A server apparatus and a server control method which transmits display data to a client apparatus and which displays the display data on a display screen of the client apparatus, wherein there are provided a plurality of accelerators, each of the plurality of accelerators being equipped with a difference detection circuit which compares the display data for a previous screen transmitted to the client apparatus with the display data for a current screen to be transmitted to the client apparatus to detect a difference therebetween. Then, the size of a drawing area to be allocated to each of the plurality of accelerators is calculated for each of the accelerators in response to a request from the client apparatus, and when a display request is made from a new client apparatus, the accelerator having a smaller drawing area among the calculated drawing areas is allocated to the new client apparatus.

  • Patent number: 7496641
    Abstract: In a computer system in which a plurality of server units and a plurality of terminal units are connected via a network and application software is consolidated on the server units, each of the server units stores a specific file in which information on the connection with each of the plurality of server units, information on a desktop image corresponding to each of the plurality of server units, information on the specification of an application functioning on the server unit, and information on an image of its initial screen have been written, transmits the specific file to a connecting terminal unit as a result of the connection with the terminal unit, and runs the application when receiving from the terminal unit a run command for the application complying with information on the specification of the application functioning on the present server unit.

  • Publication number: 20070234229
    Abstract: When a display command received from a client apparatus is a real display command, a real display control unit extracts, out of the display data drawn in the drawing area, display data of an area corresponding to the display area of the client apparatus, and transferring the extracted display data to the client apparatus. When a display command received from the client apparatus is a real display command, a full display control unit reduces the display data drawn in the drawing area in accordance with the display area of the client apparatus, and transferring the reduced display data to the client apparatus. Even when the size of a display screen is small, the display data in the display area corresponding to a request from the client apparatus is transferred so that the display data can be displayed on the client apparatus in an easy-to-view manner.
