An image processing apparatus implements appropriate image processing on image data stored in a storage unit of the image processing apparatus easily and efficiently, and distributes the image data to an external apparatus. An image format conversion unit implements image processing such as resolution conversion processing, filter processing, &#x3b3; correction processing, and halftone processing on image data stored in an HDD serving as an image data storage unit so that the image data conform to conditions, such as image quality and format, specified by an external client apparatus. The image-processed image data are then distributed to the external client apparatus.

Image processing apparatus, image processing method, and image processing program

An image processing apparatus includes a generator, a storage, an image data format converter, and a sender. The generator generates print image data for printing an image, based on image data sent from an external device. The storage stores the print image data. The image data format converter converts the print image data into image data in a format handled by an external device. The sender sends the converted image data via an IP (internet protocol) network to the external device. The image data format converter performs one of color space conversion, expansion, compression, resolution conversion, filtering, halftone processing, density gamma conversion, and noise removal in accordance with parameters determined based on at least one of property information of the print image data and property information requested by the external device.

Apparatus, method and program for image receipt, processing, conversion, and delivery to and from a plurality of external apparatuses

Apparatuses, methods, and computer readable medium for processing image data based on property information to enhance usability of the image data

An image processing system connects a plurality of clients to an image processing apparatus via a network. The image processing apparatus includes a reading device that reads an image of an original document and generates a prescribed image signal, an image data generating device that applies prescribed image processing to the image signal to generate image data, and a memory that stores the image data. A format converting device is provided to convert an image format of the image data selected from the memory by one of plurality of client apparatuses into a prescribed format in accordance with a format condition designated by the client apparatus. A delivering device is provided to deliver the image data to the client apparatus in the prescribed format.

Format convertible image processing system, and program

An image processing apparatus connected to an external apparatus via a network includes an selecting unit for selecting an application mode and an image quality mode, a scanning unit for scanning an original document, a scanning correction unit for generating image data from the scanned document, a storage unit for storing the image data and the process mode information, a compression unit for compressing the image data, an extension unit for extending the compressed image data, a data format converting unit for converting a data format of the image data according to the application mode and the image quality mode, and a communication unit for communicating the image data with the external apparatus. The data format converting unit receives image data having a first data format, and outputs the image data having a second data format, wherein the first and second data format are either a data format dedicated to the image processing apparatus or a general data format.

Image processing apparatus, image data generation and transmission method and image data generation and transmission program

An image forming apparatus for calculating a masking coefficient is provides, in which the masking coefficient is calculated by using RGB input image signals obtained by reading a document of which spectral characteristics are known by an image reading part and CMYK output image signals optimal for reproducing a color of the document. The masking coefficient can be also calculated by using difference values between CMYK output image signals obtained from actually read RGB signals and optimal CMYK output image signals.

Image forming apparatus and masking coefficient calculation method

An image forming apparatus of the type sequentially transferring a plurality of toner images formed on an image carrier to an intermediate image transfer body one upon the other (primary transfer) and collectively transferring them from the intermediate image transfer body to a recording medium (secondary transfer) is disclosed. The intermediate image transfer body is implemented by a roller including a metallic core, a base layer formed on the core, and a surface layer formed on the base layer. The base layer and surface layer have a total resistance between 1.57&times;10,&OHgr; and 1.57&times;10,&OHgr; for a unit length (1/cm). The surface layer has a volume resistivity between 1&times;10,&OHgr; cm and 1&times;10,&OHgr; cm. The roller is free from defective image transfer ascribable to the varying environment.

Image forming apparatus including an intermediate image transfer body

An image forming apparatus includes an image carrier, an intermediate transfer element to transfer a developed image, an electrode to apply a bias having preselected polarity to the intermediate transfer element and form an electric field. The intermediate transfer element has an adhering force acting on toner of the developed image that is greater than or equal to an adhering force acting between the toner and the image carrier, and when a frictional charging polarity of the toner which rubs against the intermediate transfer element is the same polarity as the bias applied to the intermediate transfer element from the electrode.
