  • Publication number: 20070025623
    Abstract: An image distribution apparatus divides image data of a single frame into a plurality of blocks, orthogonally transforms the blocks and calculates transformation coefficients, quantizes the calculated transformation coefficients, codes the quantized transformation coefficients, and distributes the coded image data. The image distribution apparatus acquires the quantized transformation coefficients, stores the acquired transformation coefficients in a storage unit, calculates differences between the transformation coefficients of a first frame and the transformation coefficients of a second frame stored in the storage unit in a unit of block, counts blocks whose difference values calculated above are equal to or greater than a predetermined value as changing blocks of the first frame, and determines that the first frame has changed when the counted number of blocks is equal to or greater than a predetermined value.

  • Publication number: 20060022814
    Abstract: When a plurality of objects having RFID tags attached are to be read, an image sensing unit performs image sensing, and at the same time an RFID reader reads an RFID tag within the image sensing range. A characteristic quantity (external appearance model) of an object obtained from a database on the basis of ID data of the RFID tag is compared with a characteristic quantity obtained by image processing of the sensed image, thereby acquiring information unique to the object. The object is discriminably specified by superimposing the acquired unique information on the object in the sensed image.

  • Publication number: 20030061322
    Abstract: A network device control unit and method are provided in which, not all MIB objects under the control of the network management software are simultaneously acquired during startup of the network management software so the almost simultaneous flow of a large volume of SNMP packets in the LAN will not occur and along with a simultaneous reduction in the load on communications lines, the load on devices such as the printer and network board processing their SNMP packets will also become small. To accomplish this, windows allocated to individual network peripheral devices on a one to one basis and controlling the network device are utilized as device windows, and information to be displayed on the initial screen of the device window is acquired as the initial sheet and displayed. Device windows also acquire and display different sheet information on the device window when determined an entry has been made by the user requesting display of a different type of sheet information.
