A control device includes a second sub-controller to which second devices are connected, a first sub-controller to which first devices are connected, a master controller that controls the first and second sub-controllers, and so on. The second sub-controller includes a second interruption information memory storing second interruption information output from the second devices, a second interruption controller transmitting an interruption signal upon storing of the second interruption information and transmitting the second interruption information, and a synchronization signal generator transmitting a synchronization signal that is synchronous with the interruption signal. The first sub-controller includes a first interruption information memory storing first interruption information output from the first devices and the second interruption information, a first interruption controller transmitting the interruption signal and transmitting the first and second interruption information, and a synchronization signal controller controlling a storage operation of the first interruption information memory in accordance with the synchronization signal.

Control device, image forming apparatus, and control method

A control device includes a second sub-controller to which second devices are connected, a first sub-controller to which first devices are connected, a master controller that controls the first and second sub-controllers, and so on. The second sub-controller includes a second interruption information memory that stores second interruption information output from the second devices, and a second interruption controller that transmits an interruption signal upon storing of the second interruption information in the second interruption information memory, and reads and transmits the second interruption information. The first sub-controller includes a first interruption information memory that stores first interruption information output from the first devices, and the second interruption information transmitted from the second sub-controller, and a first interruption controller that transmits the interruption signal received from the second sub-controller, and reads and transmits the first interruption information and the second interruption information stored in the first interruption information memory.

Control device, image forming apparatus, and control method for processing interruption information

A control device includes an apparatus controller that is connected to at least one apparatus and includes a first memory which stores data for controlling the driving of the apparatus and data indicating a state of the apparatus and a reading and transmitting unit which reads each data item stored in the first memory and transmits the read data, a main controller that includes a central processing unit, a second memory, and a writing unit which writes the data transmitted from the apparatus controller to the second memory, and a full-duplex serial bus that connects the main controller and the apparatus controller. The reading and transmitting unit and the writing unit operate such that each data item stored in the first memory is read, transmitted, and stored in the second memory in a cycle equal to or less than a count cycle of a system timer.

An image formation system includes I storage units, an assignment unit that assigns to the storage units storage destinations of color component data forming a part of image data, J color component image formation units that form color component images of corresponding colors based on color component data stored in the storage units, and an image formation unit that forms an image of the image data based on the formed color component image, wherein the assignment unit includes a J-color assignment unit that assigns to the I storage units storage destinations of J sets of color component data forming a part of J-color image data, and an L-color assignment unit that assigns a storage destination of L sets of color component data forming a part of L-color image data to N storage units among the I storage units, and each of I, J, and N is a natural number greater than or equal to 2, L is a natural number greater than or equal to 1, L&#x3c;J, and L&#x3c;N&#x2266;I.

Image formation system, image formation program recording medium, and image formation method

The image forming system is provided with: a printer that superposes and transfers plural images formed by use of plural image forming materials to a medium; and a data processor that supplies data of the images to the printer. The data processor includes: a data generation unit that generates data of image components corresponding to the respective kinds of the image forming materials; a data forwarding unit that forwards the generated data to the printer; and an assigning unit that assigns the image components in accordance with the data amount of the forwarded data. The printer includes: an output controller that controls an image forming mechanism to form an image by use of the image forming materials; and a switch processing unit that transmits the data received from the data processor, to the output controller corresponding to the image components of the received data.

Image forming system, data processor and data processing method

A computer readable medium stores a program causing a computer to execute image process, wherein the image process includes accepting image information, accepting a searching condition, specifying colored regions in an image produced by the image information, searching the specified regions for a region satisfying the searching condition, and outputting information on the region satisfying the searching condition.

Non-transitory computer readable medium for image processing searching colored regions for region satisfying searching condition, and image-processing apparatus for performing the image processing

When image synthesis using form data, for which a pass code has been set, or merge data, for which a password has been set, is completed, the synthesized data is encoded and held. Thereafter, a client terminal is notified by e-mail that image synthesis has been completed. Thereafter, when a request for output is inputted, collation of passwords is carried out. If the passwords match, decoding and printing-out of encoded synthesized data, or transmission of the encoded synthesized data is carried out.
