  • Patent number: 6278862
    Abstract: A method and apparatus is described for enhancing the communication of data in an alphanumeric paging network. In accordance with the present invention, caller-identification information is automatically transmitted through a telephone network to a central office of a alphanumeric paging network when a page-originating communicant engages the network. The caller-identification information preferably includes numeric data which identifies the telephone number of the particular telephone unit utilized by the page-originating communicant to engage the alphanumeric paging network, and alphanumeric text which identifies the entity associated in the telephone directory with that particular telephone number. This information may be utilized in an automated fashion to reduce the required interaction between the alphanumeric paging network and the page-originating communicant. In particular it is helpful in minimizing the amount of human interaction required.

  • Patent number: 5880856
    Abstract: Disclosed herein is a method of storing and of progressively transferring a still image so that it can be conveniently previewed during the transfer and so that a user can terminate the transfer at an early stage if the image turns out to be undesirable. The methods of the invention include transforming the image into a plurality of decomposition levels using a discrete wavelet transform. Each decomposition level comprises a plurality of subimages which allow reconstruction of an image representation of the still image. The decomposition levels are transmitted beginning with a base decomposition level providing a low level of image resolution and then proceeding with decomposition levels providing increasingly higher levels of image resolution. Within each decomposition level, rows of the various subimages are arranged or interlaced together in contiguous blocks, so that all data for a single row, at a single decomposition level, is transmitted together.

  • Patent number: 5838458
    Abstract: A method and apparatus for receiving document images including portions linked to one or more electronic addresses. The linked portion of the document is identified using a predetermined visual attribute, such as bold-face text, or delimiters to mark the portion. The document image is then transmitted using, e.g., existing apparatus for transmitting images, such as a facsimile machine. An electronic address associated with the identified portion of the document is also transmitted using existing techniques, such as by touch-tone telephone. The address may be a voice telephone number, facsimile telephone number, World Wide Web address, or any other address with which communication can be established. At the receiving end, both the document image and electronic address are received. Pattern matching is performed on the document image to identify the portion with the predetermined attribute as a linked portion. The received electronic address is then correlated with the linked portion.

  • Patent number: 5825928
    Abstract: A motion image decoding apparatus receives encoded image data which has first, second and third data regions, such as MPEG macroblocks which have predetermined sizes, and a motion vector for each of the data regions. The motion image decoding apparatus conceals errors in the first data region by generating an error signal and using a motion vector of a second data region which is located on a line preceding a line containing the first data region having the error and which is in a same picture as the first data region and also by using a motion vector corresponding to a third data region which is located in a column preceding the column containing the first data region having the error and which is also in a same picture as that of the first data region. If no error is generated in the first data region, the motion vector for that data region is used to perform motion compensation.

  • Patent number: 5784500
    Abstract: A binarization circuit compares the density value of the target pixel with the density value of surrounding pixels in the vicinity. A judging unit judges whether or not the target pixel is isolated from the surrounding pixels. A detection unit detects the density values of the target pixels which make the target pixels isolated by a binarization process. A calculation unit calculates the accumulated isolated pixel frequencies of each density value detected by the detecting function when the judging unit and the detecting unit have finished processing all of the original image. A determination unit determines a threshold value on the basis of the accumulated isolated pixels frequencies.
