Image data scanned by way of a scanner controller is transferred from a memory controller to a memory by way of a G bus. A CPU reduces the image data stored in the memory by thinning processing or the like, and displays the image data on an operation panel by way of a B bus and interface. In this manner, an image can be input using the first bus while data transferred by way of the first bus is output by way of the second bus. This enables processing using image data which is being input, such as processing of immediately displaying an input image.

Input/output control apparatus

Control unit selectively connected with a first bus and a second bus for controlling a displaying process in parallel with a scanning process

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

A generated job is divided in units of pages, and devices for executing processes for the respective pages are assigned. Processes by the first and second CPUs are assigned in accordance with whether a large or small number of real-time operations are required in data processing. By controlling the use of a plurality of buses so as to perform processes in units of pages in parallel, the throughput of data processing can be increased.

Information processing system for composite appliance

A generated job is divided in units of pages, and devices for executing processes for the respective pages are assigned. While the processing results of the devices for pages as processing units complement each other so as not to decrease the communication or data transfer speed by controlling the use of a plurality of buses, data are written and read in parallel.

Information processing method and system for composite appliance

In order to manage the amount of power consumed by executing a plurality of jobs in parallel to a proper level, when a job start key is pressed, whether power consumption exceeds a predetermined value is determined. If the power consumption does not exceed the predetermined value, the job is executed; otherwise, the job is not executed, and the processing waits for a next instruction.

Control device and control method for composite appliance

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 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

This invention relates to a method and apparatus for processing an image and particularly a method and apparatus for providing a function of automatically judging whether an input image is a color or monochrome image. This invention discloses various arrangements for preventing errors in the above judgement.

Method and apparatus for processing image

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

In a memory-to-memory data transfer apparatus, each of a plurality of memories connected to a memory bus is sequentially selected, and data which occupy predetermined positions in the data read from the selected memory are combined into a set of data. The set of data is sequentially written while addresses in the remaining memory is being updated. Alternatively, a plurality of sets of data are sequentially read out while addresses in a memory are being updated, and data which occupy predetermined positions in the read data are combined into a set of data. The set of data is written while the remaining memories are being sequentially selected. The apparatus may have a plurality of memories connected to a data bus and address generators for generating unique addresses for each of the memories in accordance with a predetermined synchronizing signal. The apparatus, in preferred form, effects transfer of data in thinned-out form or phase-divided form by shifting a generated address or by adding a predetermined value to the address.

Apparatus for combining and separating color component data in an image

An image processing system, particularly for a color image, capable of various and precise image processings. For this purpose there are provided a memory for ordinary image processing, additional memories for expanding the memory capacity, and a system bus, an address bus and a high-speed transfer bus connecting these memories for enabling mutual data transfer and integrated use of said memories.
