  • Publication number: 20020047835
    Abstract: An image display apparatus has a data display region on which image data is displayed, and a user interface region on which a plurality of icon images are displayed. The icon images displayed on the user interface region each include a left-eye image and a right-eye image so as to be stereoscopically displayed. The image display apparatus provides stereo vision such that the icon images are projected toward a viewer with respect to a normal state when a cursor implemented as a pointer overlaps the icon images, and the icon images are projected away from the viewer with respect to the normal state when the icon images are clicked.

  • Patent number: 6139956
    Abstract: Depositing a thermoplastic resin powder in between the individual fibers of a reinforcing continuous fiber bundle and subsequently applying a solution of a binder resin dissolved in a solvent to the resulting reinforcing continuous fiber bundle, the thermoplastic resin powder is fixed in between the individual fibers via the binder resin which concurrently works to bind the individual fibers together. Then, the solvent of the binder resin is substantially removed from the resulting reinforcing continues fiber bundle within a temperature zone not above the melting point or flow point of the thermoplastic resin powder. In the molding material produced by the method, the individual fibers of the reinforcing continuous fiber bundle, the individual fibers and the thermoplastic resin powder, and the individual thermoplastic resin powders are independently fixed together, all in a pin-point fashion via the binder resin, so the molding material substantially does not contain the solvent of the binder resin.

  • Patent number: 6075619
    Abstract: An image encoding apparatus, as well as a method, which can suppress degradation of image quality in the image region which contains a predetermined color. The apparatus has a block data acquisition unit which divides inputted color image signal into plurality of block data, a specific color proportion measuring unit which measures proportion of the specific color in block data inputted thereto so as to produce a specific color proportion information signal, an orthogonal transformation unit which performs orthogonal transformation of block data as to output a transform coefficients, and a quantization unit which quantizes the inputted transform coefficients in accordance with the specific color proportion information signal so as to produce quantized data. The quantized data is then encoded into variable-length codes, whereby compressed data is obtained.

  • Patent number: 6029198
    Abstract: A network device control method and apparatus for controlling various devices connected to a network cause a setting sheet that is for setting the environment of a device to be displayed on a screen so that the environment of the device may be set. A request for read-out of management information corresponding to each control on the setting sheet is transmitted to the network. If read-out of the management information succeeds, the information is set in the corresponding control and the display state thereof is enabled. If read-out fails and the reason is that the device does not support the date, then the name of the control is displayed in gray and the display is not displayed at all. If the function is one supported by the device, on the other hand, then the name of the control is displayed at ordinary brightness and the corresponding data is displayed in gray.
