The image processor has a halftone processing unit which converts the grayscale input data of pixels into image regeneration output data corresponding to a dot size of pixels, and a lookup table including a plurality of gamma tables storing image regeneration output data corresponding to the grayscale input data, corresponding to the position of the pixels of the grayscale input data. In the lookup table, a virtual representative gamma table is allocated to each identical index pixel group dispo...

Aspects of the invention can provide an image processing circuit for gray scale correction, an image display apparatus, and an image processing method that allow reduction in the storage capacity needed for storing correction characteristics data without increasing clock rate in relation to interpolation processing of correction characteristics. A exemplary image processing circuit according to the invention can be applied, for example, to color correction or gamma correction of color image data...

In an image data processing device, a notice pixel is selected from among a plurality of pixels constituting an image. A specified direction in which ink ejected on a recording medium would bleed by a relatively large amount on the recording medium is obtained. Then, a color-difference vector indicative of the magnitude and direction of a color-difference between the notice pixel and neighboring pixels disposed adjacent thereto is calculated, and a directional component which is a component of t...

Computer-readable media having computer-executable instructions provide support for the printing of documents containing embedded interactive code information in conjunction with different applications that include Microsoft Word, Microsoft PowerPoint.RTM., and Microsoft InfoPath.TM.. With a Microsoft Word document, the contents and the associated portion of the EIC pattern are printed page by page. A virtual printer intercepts a spooled printed job and saves the associated enhanced metafile. Su...

The image forming apparatus comprises an image reading device that reads a manuscript and generating a manuscript image data, and a command input device that inputs a command. A layout analysis device is provided for analyzing a layout of an image expressed by the manuscript image data. A controller is provided which, when a command is inputted trough the command input device, decides a page order for horizontally or vertically juxtaposed pages based on a result of analysis by the layout analysi...

An electronic file corresponding to a scanned original image is specified on the basis of the original image. If the electronic file corresponding to the original image cannot be specified, the original image is converted into vector data. The vector data is converted into image data. The first image data of the original image is compared with the second image data generated by the second conversion unit. On the basis of the comparison result, the first image data or vector data is selected as t...

The technique of the invention sequentially supplies dot data to multiple dot formation elements, which are actuated to create dots simultaneously on multiple pixel arrays arranged at preset intervals, and thereby completes a resulting output image on an output medium. The procedure temporarily stores received dot data in a memory, reads out only dot data of the multiple pixel arrays, on which dots are to be created simultaneously by the multiple dot formation elements, converts the read-out dot...

An image processing apparatus includes an image capture apparatus with a reduced size for capturing still image data. An extracting circuit extracts at least an area of still image data. A dividing circuit divides the area extracted by the extracting circuit into a plurality of first through nth areas. A memory circuit has a storage capacity smaller than a storage capacity required to store the still image data, and stores at least a portion of the image data of the first through nth areas provi...

Methods, apparatus, software, and systems of the present invention allow for optimization of color and shades of gray documents prior to their conversion to a monochrome format. If color/gray elements are identified in the document, the distance between them and their intensity is determined. If there are elements with the same or similar intensity in close proximity to each other, colors of some of the elements may be replaced with solid monochrome colors, and/or dithered surfaces, and/or monoc...

A method and system for monitoring and controlling machines, such as printers, copiers, facsimile machine and other image forming machines. A server is used for transmitting and communicating information among machines and computers. The server acquires, after machine installation, reference values and during operation, current condition information. The server evaluates this information with the reference values such that a response to the machine may be executed remotely. The server also may u...
