An image forming apparatus analyzes image data corresponding to a received job, and when as a result of the analysis is that the image data has a resolution that exceeds a predetermined value, determines a size of a sheet to be printed, and when a result of the determination is that the size of the sheet is a predetermined size, if a size of the image data is less than or equal to a threshold, stores image data to which halftoning processing is not performed in a memory, and if the size of the image data exceeds the threshold, stores image data to which the halftoning processing is performed in the memory, and based on a direction of the sheet, performs image forming on the sheet after performing rotation processing for the stored image data.

A method for reducing image burn-in artifacts in an electrophotographic printing system, includes receiving a print job including image data for a set of pages to be printed. The pages are analyzed to determine that the image data for a sequence of pages in the print job are similar. The similar pages are printed using a pattern of lateral translations wherein the image data is laterally translated such that it is printed at a different lateral position on the printed page.

A method for reducing image burn-in artifacts in an electrophotographic printing system, includes receiving a print job including image data for a set of pages to be printed. The pages are analyzed to determine that the image data for a sequence of pages in the print job are similar. The similar pages are printed using a pattern of page orientations including a first page orientation and a second page orientation, wherein the image data for the second page orientation is rotated 180 degrees relative to the image data for the first page orientation.

An image processing device includes a dithering circuit, a gradation correction pattern generating circuit, and a gradation correction pattern correcting circuit. The dithering circuit performs a dithering process on image data to generate dithered image data. The gradation correction pattern generating circuit sets, in multi-valued data, gradation information of each of pixels of the generated dithered image data, and generates a gradation correction pattern imitating the dithered image data. The gradation correction pattern correcting circuit performs pattern matching on the generated gradation correction pattern, and corrects the generated gradation correction pattern in accordance with a result of the pattern matching.

A printing device displays a preview image of received image data, receives, based on the previewed image, an instruction to rotate the received image, rotates the received image data based on the received rotation instruction, and prints the rotated image data.

An image forming apparatus receives a print setting for image data, determines a density correction table to be applied to a position of a pixel in the image data based on the received print setting from among a plurality of stored density correction tables, and corrects a density of the image data using the determined density correction table.

An information processing device includes: a scanner that performs scanning of a read image of a document and detects a code image included in a scanned region, which is a region where the scanning is completed; and a setting unit that sets, based on the code image detected by the scanner, a scanning region when the scanner scans an unscanned region, in which the scanning by the scanner has not been performed yet.

A method of controlling an information processing apparatus includes displaying an edit screen including an obtained image and a print range frame based on obtained print setting information, accepting an edit operation of arrangement of the image in the edit screen, generating image data based on an edited image, and transmitting the generated image data and the print setting information to the image forming apparatus as a print job. Where the image has been edited such that there is a region where the image is not arranged in the print range frame, combining processing in which a predetermined image is added in the region is performed and whereby image data including the image and predetermined image is generated, and where the image has been edited such that there is no region where the image is not arranged in the print range frame, the combining processing is not performed.

A method for reproducing images comprises the steps of: obtaining 1.sup.st to N.sup.th scan images in order, where N is a positive integer greater than 2; processing the 1.sup.st to N.sup.th scan images into 1.sup.st to N.sup.th document images and obtaining sizes of the 1.sup.st to N.sup.th document images; and performing an ordered document typesetting according to an ordered accumulated size of the 1.sup.st to N.sup.th document images to generate image data corresponding to one or multiple output pages. An image-processing apparatus is also provided. Thus, it is possible to prevent the waste of printing a small-size document image on a large-size sheet, and the user can obtain the order of documents according to the order of the output pages. So, an instinctive and environment protective copying technical solution can be provided, and an output result can be further adjusted.

An image reading apparatus of an embodiment includes a reading unit and a controller. The reading unit simultaneously reads a plurality of documents on a document table and generates an overall scan image as color image data including images of all the documents in the plurality of documents. The controller is configured to isolate an image of each document from the overall scan image, perform a color determination on each of the isolated images to determine if the document corresponding to the isolated image is a color document or a non-color document, and encode each of the isolated images with an image encoding method selected based on the color determination for the isolated image.
