An image processing apparatus provided with a reader for reading an original image, a connection unit for connection with a network to which plural computers are connected, and a transfer unit for transferring the image data, read by the reader, to a computer through the connection unit, the apparatus comprising a specifying unit for specifying a desired one among the computers connected through the connection unit, and a designation unit for designating image reading by the reader, wherein the transfer unit is adapted to transfer the image data, read by the reader in response to the designation by the designation unit, to a computer specified by the specifying unit.

When a plurality of sub-processors are daisy chained in a loop, for example, to a main processor by a one-way bus, a command packet from the main processor addressed to itself is transmitted to the one-way bus which form a return path back to the main processor so as to easily specify a fault portion. If the command packet is returned to the main processor within a predetermined time, it is determined that no fault exists within the electronic device. When a fault exists, a test signal is transmitted to sub-processors via a dedicated signal line, separate from the one-way bus, to trigger a test packet that will be routed through the one way bus. The faulty portion in the electronic device is specified based on whether the test packet transmitted via the one-way bus in accordance with the test packet from each sub-processor is received within a predetermined time.

Electronic device including image forming apparatus

In a network connecting a plurality of devices, the image processing function of each device, information for specifying each device, and the like are collected and controlled, and functions realizable by combining two or more devices are determined. Profiles indicating respective combinations are transferred to each device. Each device which has received the profiles displays executable functions based on the profiles, and performs control, such as the operation of the device, transfer of data, and the like, in order to realize a function selected from among the displayed functions.

Data processing apparatus connected to a network connectable a plurality of devices

Image reading device and image process method utilizing the same

Each of input and output devices previously forms device profile, and a host computer acquires virtual input/output device information including a pair of ideal input and output devices on the basis of the device profiles of these devices. If the virtual input/output device information is acquired, the input device demands to acquire a transfer path profile included in the virtual input/output device information, and then demands if the transfer path profile is acquired the output device registered in the acquired transfer path profile to connect a line. If the line connection is established, the input device performs data inputting such that the acquired transfer path profile is reflected in the device setting, and then it transfers the input data to the desired output device.

Information processing system and information processing method

Determination is made whether or not memory contents have been changed for each memory block. A physical memory corresponding to the memory block whose contents have not been changed is released as an area where no rendering data is stored. Then such area is managed distinguishably from other areas where rendering data are stored. As a result, memory areas are effectively utilized.

Image forming apparatus and image forming method

The present invention is to provide an image processing apparatus which comprises connection means for connecting to a computer network to which a plurality of computers are connected and record means for recording and outputting image data sent from the computer through the connection means, the apparatus comprises access means for accessing one of the plurality of computers, selection means for selecting a file to be recorded and output by the record means, from among the files managed by the computer accessed by the access means, and request means for requesting, to the computer accessed by the access means, a sending of the image data in the file selected by the selection means, wherein the record means records and output the image data sent from the computer in accordance with the request means, whereby the image processing apparatus can access the computer which is placed far from that apparatus and output the contents of the computer.

Image processing apparatus

Input first image data and second image data are added with attribute data representing attributes of the respective data, the first and second image data respectively added with the attribute data are multiplexed, the attribute of the image data is analyzed based on the attribute data added to the multiplexed image data, and a first image process is performed to the first image data in the multiplexed image data and a second image process is performed to the second image data, in accordance with the analyzed attributes.
