  • Patent number: 6945704
    Abstract: An optical connector 1 includes a first connector 2 and a second connector 3. The first connector 2 includes a first ferrule 4 and a first housing 5. The terminal of an optical fiber 7 is attached to the first ferrule 4. The first housing 5 accommodates the first ferrule 4 so as to be movable along the axial line P of an optical fiber cable 7. The second connector 3 includes a second ferrule 20, a second housing 21 and a coil spring 23. The terminal of another optical fiber cable 7 is attached to the second ferrule 20. The second housing 21 accommodates the second ferrule 20 and the coil spring 23. The coil spring 23 urges the second ferrule 20 toward the first connector 2. Such a configuration provides an optical connector which permits the housings to be easily coupled with each other and suppresses the labor for assembling the connector.

  • Patent number: 6934416
    Abstract: A video encoding apparatus is provided with a resolution converting section, an encoding section, and a transmitting section. The resolution converting section enlarges or reduces a binary picture which represents the shape of an object. The encoding section encodes a binary picture reduced by the resolution converting section. The reduction ratio used by the resolution converting section is encoded, and the transmitting section transmits this encoded reduction ratio along with encoded data on the binary picture. The amount of encoded data produced from the encoding section is controlled by changing the enlargement/reduction ratio used by the resolution converting section.

  • Patent number: 6897881
    Abstract: An image displaying apparatus includes an image storing unit storing image data containing two or more objects. An extracting unit extracts individual data from the object of the image data. An input unit inputs additional partial image data, and attribute data representing a corresponding relationship of at least part of the image data to the additional partial image data. An associating unit associates the additional partial image data with an individual data of the image data, using the attribute data input via the input unit. A synthesizing unit modifies a data content regarding at least part of the image data, which is associated by the associating unit, and synthesizes the modified content with the image data stored in the image storing unit.

  • Publication number: 20040213346
    Abstract: A coding unit generates a code of each frame of a moving image. A first verification unit calculates a first code quantity predicted to be stored in a buffer if the code were to be supplied to the buffer in a virtual decoding apparatus by a first bit rate. A second verification unit calculates a second code quantity predicted to be stored in the buffer and a change rate of the second code quantity if the code were to be supplied to the buffer in the virtual decoding apparatus by a second bit rate lower than the first bit rate. A control unit changes a coding bit rate of said coding unit based on the first code quantity, the second code quantity, and the change rate.
