Image processing apparatus, controlling method of image processing apparatus, and storage medium

When a plurality of jobs are processed using a plurality of data processing units, data formats of the jobs to be processed can be determined to distribute a data processing load of the data processing units. A method for controlling a data processing apparatus for causing a plurality of data processing units to process data of a job includes storing data of a first job in a storing unit in first and second data formats, determining whether to process the stored data of the first job in the first or second data format, and causing the plurality of data processing units to process the data in the determined data format. The determination is made based on whether processing of data of a second job by the first or second processing unit requires longer time.

Data processing using different data formats based on shared resource utilization

An image forming apparatus including a developing device corresponding to a color component, comprises: a conversion unit configured to accumulate, for each color component, values of respective pixels for each color component that fall within a predetermined range of image data, and to convert the accumulated value into a count value of the color component; an addition unit configured to add, to the image data, the count value of each color component that has been converted by the conversion unit; and a control unit configured, when forming an image based on the image data, to supply toner to the developing device of each color component in accordance with the count value of the color component that has been added by the addition unit.

Image forming apparatus, control method and computer-readable medium

There is disclosed an image processing apparatus and a control method thereof in which input image data and generates a plurality of tile images, each including a substance region and overlap regions each of which overlaps with a part of each adjacent tile image, by dividing the input image data. The apparatus executes image processing separately on each of the plurality of the generated tile images, and when generating each tile image, converts a resolution of image data in the overlap regions such that the resolution of the image data in the overlap regions is smaller than a resolution of image data in the substance region.

Processing tile images including overlap regions

An image processing system and a control method thereof are provided, which presents an appropriate image format for the image data to be stored. To accomplish this, in an image processing system comprising a plurality of image forming apparatuses and storage apparatuses, the image forming apparatuses each decide priority scores indicating priority order of each image format from the image processing information that indicates image formats of image data supported at each image forming apparatus. Further, the image forming apparatuses show the priority order based on the decided priority scores, and at the same time generates a selection screen for the user to select the image format of the image data and display it on the display apparatus provided in the image forming apparatus.

Image processing system including image format prioritizing and control method thereof

An image processing apparatus includes a connecting unit configured to connect the image processing apparatus to a network via which a plurality of image output devices can be connected to the image processing apparatus, an input unit configured to input image data, a specifying unit configured to specify an image processing attribute of the input unit, an acquiring unit configured to acquire information indicating a degree of fit between the image processing attribute of the input unit specified by the specifying unit and an image processing attribute of each of the plurality of image output devices, and a display unit configured to display a list of the plurality of image output devices with an indicator of the degree of fit based on the information acquired by the acquiring unit.

Determining a degree of fit between an image data input device and an image data output device

An image processing apparatus which permits service providing an image forming that has high priority is selected as an image processing apparatus for storing count information by using service information representing whether each image processing apparatus permits counting the usage of printing materials in order to allow charging of service for providing the image forming associated with each user identification information, and a priority table for storing count information based on the contents of image forming. When image forming is executed, the count information representing the contents of the executed image forming is transmitted to the selected image processing apparatus, thereby causing the selected image processing apparatus to store the count information.

Image processing system and control method therefor

An image forming apparatus is provided, in carrying out an image forming operation using a paper sheet, that uses a sheet containing a wireless tag that stores an address storing control information for performing an optimum image forming. The image forming apparatus obtains the address from the wireless tag using a receiving device, and obtains control information from a server via a network based on the obtained address. The image forming apparatus controls an image forming condition based on the control information, and carries out the image forming under image forming conditions optimum for the sheet.

A clock supplying apparatus capable of suppressing a current fluctuation as much as possible when supply of a clock signal to a circuit block is started or stopped. At start or termination of the clock signal supply to the circuit block, the clock signal frequency is temporarily changed to a low frequency lower than a standard frequency.

Clock supplying apparatus and control method thereof

A data receiving system which enables, even when the location of a recipient is changed, a sender to always send data to the same transmission destination, and the recipient to obtain received data from a nearest output terminal apparatus. A server as the data receiving apparatus receives data addressed to an IP address, as received data through the Internet. A multi-function peripheral as an output terminal apparatus receives the received data from the server and outputs the same. In this case, the server selects the multi-function peripheral from registered multi-function peripherals based on the IP address to which the received data is addressed, and relationship map information, and then transfers the received data to the selected multi-function peripheral.

Recent copying machines have higher image quality, and the halftone processing methods are diversifying. If automatic tone correction is applied in correspondence with the diversified halftone processing methods, a long operation time is required. Hence, a sample chart based on the sample data is formed by a printer.
