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

The image data corresponding to an image is separated into areas corresponding to contents of the image. The image data in each of the area is subjected to an image processing specific to the content of the image. The image types are, for example, a character, a photograph, color, and presence of halftone. The image processing are, for example, gamma correction, color conversion, and gradation processing. The processed image data is then transferred to an external device via network.

Image processing apparatus for transmitting image data to an external device

A spatial filter applies a modulation transfer function correction process so as to increase a number of bits of input image data. A high-resolution converter converts the image data into output image data having a density higher than a sampling density of the input image data. One of the spatial filter and the resolution converter processes the image data after the other of the spatial filter and the resolution converter has processed the image data A possibility of saturation of an output of the spatial filter is decreased, thereby decreasing generation of moir&#xe9; in a saturation calculation.

A coding and decoding method includes the step of a) classifying an input multi-level image into edge parts and non-edge parts according to edge degree thereof; b) coding the input multi-level image according to a coding scheme different between the edge parts and non-edge parts; and c) decoding coded data according to a linear interpolation scheme, a cubic-function convolution scheme or an interpolation scheme having smoothing performance for generating pixel values included in the non-edge part.
