  • Patent number: 6873736
    Abstract: The present invention provides a method of supplementing a digital picture with a shorter delay time and less calculations. The padding method is applied to a picture having a great motion, and results in producing a prediction signal with small errors. The present invention also provides an apparatus using the same method. To be more specific about the method, in a digital picture data including picture information indicating an object, a picture is resolved into a plurality of regions adjoining with each other, and each of the insignificant sample value of a region containing the boundary of the object shape is supplemented (padded) by the values obtained from transforming of the significant pixels near to the insignificant pixels.

  • Patent number: 6577771
    Abstract: A method for supplementing a digital image with picture elements, by which prediction signals having small errors can be generated for a digital image in which objects move greatly through a process which does not cause a long delay time and does not need a large quantity of calculation. In the method, the image is divided into areas. The insignificant sampled values of the areas containing the boundary of the shape of an object are transformed with a function of significant picture element values near insignificant picture element values and used to supplement the digital image. A digital image encoder and a digital image decoder both using the method are also disclosed.

  • Publication number: 20020013789
    Abstract: A data distribution system is provided with a data edition unit for editing contents information supplied from a transmission terminal on the basis of edition information to create multimedia data. Among the contents information constituting the created multimedia data, those having relatively small quantity of data are transmitted as first data to a reception terminal, and those having relatively large quantity of data are transmitted as second data to the reception terminal according to data acquisition information supplied from the reception terminal. Therefore, among the multimedia data created at the transmission terminal, character data or the like can be immediately transmitted to the transmission terminal while video data or the like, which takes much time for transmission, can be transmitted according to the convenience of the user at the receiving end.

  • Publication number: 20010012405
    Abstract: The invention of the present application relates to an image coding method comprising a step of extracting a feature signal expressing a feature of an input image signal, such as density, contour and edge, a coding step for performing different image coding processes depending on each one of feature information of extracted feature signals, and a step of coding an identification signal for identifying each one of said plural coding processes, its decoding method, and an image coding and decoding apparatus using such method, and therefore if the input image signal has a sharp density change before after the shape boundary as in computer graphics, if there are uniform density and discrete density in every region, an efficient coding step is selected adaptively, so that an efficient coding is achieved, while a correct decoding is realized.
