An image processing unit includes a first image processing unit that processes image data from a reading unit and a second image processing unit that processes image data from either one of the first image processing unit and a storing unit. A control unit determines a processing to be performed on the image data by the second image processing unit depending on a result of a processing performed on the image data by the first image processing unit, and selects an image processing route depending on a processing to be performed on the image data by the second image processing unit.

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

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

In a first route, image data from an image reading unit is processed by both a first image processing block and a second image processing block and sent to a storage unit, and in a second route, the image data processed by the first image processing block is stored in the storage unit and image data from the storage unit is processed by the second image processing block and sent to the storage unit. The control unit switches a process of the second image processing block according to a result of a process of the first image processing block, and switches an input source to the second image processing block according to a process content of the second image processing block.

Image processing apparatus and image processing method for proceesing reading blocks

An image processing apparatus is disclosed. The image processing apparatus stores image data read by a document reading section and image data received from an external device. An image data synthesizing unit synthesizes first image data read by the document reading section and second image data read by the document reading section or received from the external device. An image correcting unit generates image distinctive data of the first and second image data. A synthesized image distinctive data generating unit synthesizes the image distinctive data of the first and second image data by referring to an LUT (lookup table) selected by a synthesized image distinctive generating rule selecting unit. A predetermined process is applied the synthesized image data based on the synthesized image distinctive data.

Image processing apparatus, image processing method, and program product for executing the method

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.

A determining unit extracts similar-characteristic areas in image data and determines a type of the characteristics of image data of each of the similar-characteristic areas, a first correcting unit corrects a characteristic of image data in each of the similar-characteristic areas to a predetermined data characteristic according to the type of the characteristics of image data of that similar-characteristic area thereby obtaining characteristics-corrected image data, a storage unit stores therein the image data and the characteristics-corrected image data, a second correcting unit corrects a characteristic of the image data and the characteristics-corrected image data stored in the storage unit to a destination-specific characteristic that corresponds to a destination to which image data is to be output, and an output unit outputs the image data having the destination-specific characteristic to the destination.

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

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.

In the image reading apparatus, reference color patches used to determine the necessity of calibration are read, and the read image for the reference color patches is stored. The read image is converted using a color conversion function from data for a device-dependent RGB space to sRGB data for a standard color space to obtain sRGB reference image data. The converted read image and the sRGB reference image are displayed on a CRT. An operator compares the two images and performs an entry operation for executing calibration if the amount of displacement between the two is significant.

Image reading apparatus, image processing apparatus, image reading method, and computer product

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.
