A database client which can access a plurality of databases copies data selected from a source database to a destination database. The database client compares attribute items of attribute information appended to the data to be copied with those which can be set in the destination database, and directly copies an attribute item which can be set in the destination database to the corresponding attribute item. On the other hand, the database client copies attribute information of an attribute item which cannot be set in the destination database to a predetermined attribute item in the destination database. In this way, upon copying data between databases with different kinds of attribute information that can be set, the destination database can hold the attribute information of the source data.

Database system, its control method, and information processing apparatus

There is disclosed a control apparatus for a scanner/printer including a unit for generating print data described in a page description language, a unit for generating a command regarding a scanner for scanning an original image, and a unit for producing the print data and the command regarding the scanner to a common device through a network.

Control apparatus for a scanner/printer

An input/output apparatus is connected to a plurality of host computers via a network and executes both a scanning function and a printing function. The apparatus includes a portion that generates image data from data input from a first one of the host computers and prints the generated image data by executing the printing function, and further includes an output device that scans image data by executing the scanning function and outputs the scanned image data to a second one of the host computers in response to a request command. As a result, the input/output apparatus may operate in coordination with a plurality of personal computers by using the network to transfer image data therebetween.

Input/output apparatus connected to a plurality of host computers via a network

A system enables the reading characteristic of an image reader in a network to be recognized by a host computer. The SP server device transfers the reading characteristics of a plurality of scanner printers to a designated client host computer and through a network.

Server device and image processing device

There is disclosed an information input/output control device and a method therefor which displays a list of identification informations indicating an information terminal device with which a functional operation can be executed in response to an acquired environmental information of the information terminal device and in accordance with an input of an indication information which instruct to execute the functional operation.

Information input/output control apparatus and method for indicating

There is disclosed an electronic filing apparatus which allows to handle files, prepared by different application programs, as the files common to these programs in easy and inexpensive manner. The drawing information, transmitted from each application program activatable by the computer system, is converted into a predetermined print data format, defined by the operating system, by the printer driver. Then the QuickDraw-common document conversion device converts the print data, converted into the predetermined print data format, into the common document file format which can be directly referred to by the plural application programs, and the common document in thus converted common document file format is stored in the data base.

Electronic filing system using different application program for

There is disclosed an information device and an information processing method which determine whether a control code constituting a document information is processable or not, transfer the document information to the other information processing device connected with the information processing device when the control code was determined to be unprocessable, and has the other information processing device executed as proxy for the original information processing device to produce an output information from the document information.

Information processing device and information processing method

A color image data processing apparatus and method for inputting color image data of a first color space, selecting representative color image data of a second color space which differs from the first color space in accordance with the input color image data, converting the representative color image data into color image data of the first color space, and computing errors between the input color image data and the representative color image data by using the color image data obtained by the conversion.

Image data converting method and image processing apparatus

An image data converting method permits performing an appropriate image process in the following manner. Data of each picture element of an n-state (n bits per pixel) image is multiplied by a constant in order to m-state-code the data (where m&gt;n). A correction value, obtained from, for example, the average density of surrounding picture elements by .gamma. correction, masking or the like, is determined and added to a value corresponding to the m-state-coded data. Further, an image processing apparatus of the present invention multi-state-codes binary color image information the quantity of which is proportional to a plurality of colors and which has been input, before image-processing the multi-state-coded color image information in order to make the information binary by a conversion-to-binary method of a density preservation type, and the image processing apparatus outputs the information.

The invention concerns a color image communication apparatus, which comprises scan conversion means for converting n-level image data received in a raster scan system via a communication line to data in a shuttle scan system, multi-level conversion means for converting color n-level data obtained from the scan conversion means for multi-level data, and color conversion means for converting color characteristics of multi-level data obtained from the multi-level conversion means from color characteristics for a communication line to color characteristics of output color recording means. The invention also concerns a color image communication apparatus, which comprises means for generating shuttle system color signal, color conversion means for converting the color signal to signal matched to standard color characteristics for a communication line, n-level conversion means for converting the converted color signal from the color conversion means to n-level signal, and means for performing data scan conversion of the n-level data from shuttle scan system to raster scan system and sending out the raster scan system n-level data to the communication line.

Color image communication apparatus and method having two modes

There is disclosed an information input/output control device and a method for controlling the same which supervises a working condition of an information terminal device connected to the information input/output control device under a network circumstance executing various functional operations, memorizes status informations in a manner enabling to be restarted and executes the functional operations in the information terminal devices other than the preceding one in response to an input of an operation cease information of the preceding information terminal device.

Information input/output control device and method therefor

A data recognition equipment includes an input device for inputting pattern data, and a selection device which recognizes a partial pattern data in the input pattern data and selects a candidate pattern for pattern recognition of the input pattern data. The equipment also includes two comparing devices. The first one compares the selected candidate with the input pattern data at a part other than the partial pattern data. The second one compares the selected candidate and the input pattern data at a part of the partial pattern based on the results of the comparison made by the first comparing device. The equipment also includes a determining device which determines the results of recognition among the selected candidates based on the results of the comparisons by the first and second comparing devices.

Data recognition equipment and method using partial pattern recognition

A color image communication apparatus can switch between a copy mode and a communication mode. In the communication mode, color space standardization conversion of objective color image data is performed, while in the copying mode, color space standardization conversion of the objective image data is not performed.
