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

An image processing apparatus in which the reusability of digital image data is improved is disclosed. The apparatus includes an image reading unit reading a draft and obtaining the digitized image data; an image writing unit printing image data on a transfer paper; a recording unit recording image data and attached information of the image data; an external I/F unit transmitting and receiving image data and attached information of the image data; a first and a second image data processing units processing the image data from the image reading unit and the recording unit, respectively; and a bus controlling unit connecting each of the units. The first and the second image data processing units match the characteristics of the image data to prescribed characteristics so that the matched image data can be usable for both the image writing unit and the external device.

Image processing apparatus

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

A disclosed image forming apparatus includes an image scanning unit configured to generate image data by converting light reflected from an optically scanned printed page into electrical signals; an interface configured to receive image data from an external apparatus; an expansion bus to which the image scanning unit and the interface are connected; a bus control unit configured to control the expansion bus; an image data storage unit configured to store the image data; at least one image processing unit connected to the expansion bus and configured to perform an image processing operation on the image data; a task management unit configured to send an image processing request to the image processing unit; and an image writing unit connected to the expansion bus and configured to print the image data on which the image processing operation has been performed by the image processing unit.

Image forming apparatus, image processing unit, image processing method, and recording medium having image processing control program with task management

An image processing device for curbing memory expansion and reducing costs while securing programming freedom by a small programmable data processing unit. A plurality of process programs and process parameters thereof, to be sequentially executed in a data processing unit, are stored beforehand in a data memory. In the data processing unit is repeated, as many times as there are process programs in the data memory, an operation in which image data to be processed are divided into plural respective divided image data as process units, and a process program, process parameters thereof and divided image data are read from the data memory, the process program is executed on the divided image data referring to the process parameters thereof, and then the divided image data after processing, the executed process program and the process parameters thereof are written back to the data memory.

Image processing device and image processing control method

An image processing apparatus capable of regulating memory increase to realize cost reduction while securing the degree of freedom in programming by means of a small-sized programmable data processing section, and thereby improving processing performance. A programmable data processing section comprises two processing sections capable of performing different processings simultaneously. Each of the processing sections repeatedly executes the steps of: reading image data from an image data storage section; reading mutually different processing programs from a processing program storage section; executing a predetermined processing in parallel on the image data; and returning the processed image data to the image data storage section.

Image processing apparatus and image processing control method

When first image data, which is in a first color space, is converted into second image data, which is in a second color space corresponding to an image output unit. Upon converting the image data, if the first image data is color data, background removal process is switched OFF. Otherwise, the background removal process is switched ON. Thus, it is possible to obtain an image desired by a user.

Image processing apparatus, image processing method, and computer product

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

The image processing device comprises a first function block section formed of functional blocks which require a supply of power so as to maintain the image processing device in an operating state when the power supply is on, and a second function block section formed of functional blocks which need not be supplied with the power so as to maintain the image processing device in an operating state even when the power supply is on. The supply of power to the second function block section can be stopped when desired, while continuing the supply of power to the first function block section, thereby saving the power.

Image processing device, method for saving power consumption of the image processing device, and a computer product

When image data is determined to be reused, a first image-data processing unit performs a first image processing on the image data, a memory device accumulates the image data on which the first image processing is performed, and a second image-data processing unit performs second image processing on the image data accumulated in the memory device. When the image data is determined not to be reused, the first image-data processing unit performs a first image processing, and the second image-data processing unit performs a second image processing on the image data on which the first image processing is performed.

A programmable image processor capable of realizing a plurality of image formation operations is comprised of an SIMD type data operation processing section, RAMs, memory controllers, and memory switches. The memory controller and the memory switches selectively connect the plurality of RAMs to the data operation processing section thereby changing the memory capacity allotted to each image formation operation among a plurality of image formation operations.
