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.
Abstract: An image forming system which freely combines functions of a plurality of devices connected on a network in accordance with necessity, and a control system for the system. Each of the plurality of devices stores information indicating functions which can be provided by the device in advance. A functional unit which serves as a supervisor collects these stored information and analyzes a combination of functions to perform operation designated by a user, based on the collected information. Then the supervisor combines the functions based on the result of analysis and performs the desired processing operation by the combination of functions.

Abstract: To reduce computational time of adaptive arithmetic encoding/decoding according to JBIG standard, a step (S21) of reading the learning table and a step (S22) of reading the prediction probability table in a pixel encoding step, which is performed when a context of all white can be applied, are omitted for a pixel following a preceding pixel whereof a normalization process (S27) is not performed, by making use of the prediction and the false approximation applied for the preceding pixel, in the method of invention.
Abstract: An image forming apparatus includes a light emitting unit having a plurality of light emitting elements each having a different spectral characteristic, a light source having a plurality of light emitting means disposed on a substrate, and a photoelectric conversion unit for converting light from an object applied with light from the light source into an image signal, wherein the light emitting unit has at least two light emitting elements having a peak wavelength difference less than 30 nm.
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.
Abstract: A film image reproducing apparatus includes an image pick-up device which picks up a film frame image recorded on a film to generate image data; an information reader which reads information about photographing conditions of the film frame image; a reproducing area designator which designates a reproducing area of the film frame image; a measuring device which measures a domestic light condition having to do with the designated reproducing area when the film frame image is picked up; a correcting device which corrects image data corresponding to the designated reproducing area using either the domestic light condition of the designated reproducing area or an undomestic light condition not having to do with the designated reproducing area; and a judging device which judges based on the information which is proper to use for image data correction, the domestic light condition or the undomestic light condition.
Abstract: The present invention relates to a scanner housing structure which includes a scanner shell for mounting therein a scanning circuit, and the scanner housing structure is drawably mounted in a scanner-receiving space of a computer and allowed to be partially or completely drawn out of the scanner-receiving space. The scanner housing structure according to the present invention provides a more convenient environment in using a scanner, and the scanner can be a part of the computer so that no more effort of a user to choose and install a scanner is needed.
Abstract: A hybrid system for digitally screening black and white and/or color images using a number of imaging techniques is disclosed. Cyan, yellow, magenta and black color separation may be processed according to the same or different methods according to gray levels or other factors, in order to optimize output print quality.
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.
Abstract: An apparatus stores image data sent as a facsimile signal through a line in an image memory (103) and records the image data on a recording medium upon reducing the data. The apparatus further includes an interface for connection with an external information processing unit such as a personal computer so that image data input from the external information processing unit through the interface can be stored in the image memory (103) and recorded on a recording medium. Designation of image data in the image memory (103) is allowed from the external information processing unit. The designated image data is retained after a recording operation. In addition, a reducing/recording operation is inhibited when the designated image data is to be recorded.
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.

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.
