Abstract: An information processing apparatus includes a processor configured to: obtain plural page images obtained by reading pages; identify, in two page images that are target pages among the plural page images, a torn part in edge parts adjacent to each other when the target pages are two facing pages that show one image; and detect and output the two facing pages by using an obtained result of identification.

Abstract: An image forming apparatus includes a processor configured to: insert an unprinted page between unremoved pages in order to perform duplex printing, if a number of removed blank pages between the unremoved pages is an odd number of one or three or more on a digital file that has the blank pages removed when a document formed on duplex pages is read.

Abstract: An image processing apparatus includes a processor configured to: obtain image information by reading a document image; divide a single page in the obtained image information on the basis of a predetermined block unit; count black points in each block obtained through the division; use the counting result of black points in each block to determine whether the document image is a layout image in which multiple images are allocated in a single page, and to detect and delete a blank-sheet image in the layout image.

Abstract: An information processing apparatus includes an acquisition unit that acquires a designated color which is designated as a color, which is converted into a specific color, of a pixel among pixels which express an image, a determination unit that determines whether or not a common color area, which is expressed by pixels in a common hue range, expresses prescribed information in the image, and a conversion unit that performs a first conversion process of converting a pixel corresponding to the acquired designated color into a specific color in the common color area which is determined to express the information, and performs a second conversion process of converting a pixel corresponding to a color in a wider hue range than the designated color into a specific color in the common color area which is determined to not express the information.

Abstract: An information processing apparatus includes a recognition unit that recognizes an object which is included in an image and is expressed using a single color, and a conversion unit that performs conversion on a pixel, which is included in the image and corresponds to a designated color, into a specific color, and, in a case where a color of an area, which is in contact with an outer edge of the recognized object, is designated and a difference between the color of the recognized object and the specific color is smaller than a first reference, performs conversion on a pixel of the outer edge into a color other than the specific color.

Abstract: An image forming apparatus includes a memory, and a processor configured to: read a first image of a sheet in a state in which the sheet is held on a sheet holding unit, the sheet being a sheet on which an image has been formed; detect a symbol from the first image of the sheet which has been read, the symbol indicating an orientation of the first image; and, when the orientation of the first image indicated by the detected symbol is different from an orientation of a second image that is to be formed on the sheet, perform a correction process of matching the orientation of the first image with the orientation of the second image that is to be formed on the sheet, the orientation of the first image being indicated by the detected symbol.

Abstract: An image forming apparatus includes a memory and a processor configured to output an image formed based on image data including predetermined specific text after replacing a color of one or more portions in the image data with a special color that is in advance associated with the specific text, the one or more portions being assigned a color identical or similar to a color of the specific text to form the image.

Abstract: An information processing apparatus includes a detector, a receiver, and an image processor. The detector is configured to detect a punch hole candidate partial image having a punch hole accuracy indicating whether the punch hole candidate partial image is a punch hole image is less than a first threshold value and equal to or greater than a second threshold value smaller than the first threshold value, from plural partial images constituting a read image of a document. The receiver is configured to display the punch hole candidate partial image, and receive an instruction from a user as to whether to perform image processing on the punch hole candidate partial image. The image processor is configured to perform the image processing on the punch hole candidate partial image when the receiver receives an instruction to perform the image processing on the punch hole candidate partial image.

Abstract: A reading method guidance apparatus includes a receiving unit, an acquisition unit, and a guidance unit. The receiving unit receives a document size that is a size of a document as a reading target. The acquisition unit acquires an image of at least a partial area in the document. The guidance unit provides an operator with guidance about a reading procedure when the document is read by a first reading apparatus in plural batches, using a feature amount obtained from the acquired image, the received document size, and a readable size that is a size of an area readable by the first reading apparatus.

Abstract: A document size detecting apparatus includes a first acquisition unit, a second acquisition unit, and a detector. The first acquisition unit acquires a first image that is an image of an entire document as a reading target. The second acquisition unit acquires a second image that is an image of a part of the document read by a first reading apparatus. The detector detects a size of the document using a result of a matching process between the first image and the second image and a read size that is a size of the second image read by the first reading apparatus.

Abstract: An image processing apparatus includes the following elements. A characteristic value calculator calculates characteristic values of a preset area set around a pixel of interest. A trapping determining unit determines, for each color plane of an N-valued image, on the basis of the calculated characteristic values, whether the pixel of interest is to be subjected to trapping processing. A pixel value calculator sets, for each color plane, a position of a reference pixel in a reference area, and calculates a pixel value for changing the pixel value of the pixel of interest on the basis of a pixel value of each color plane at the position of the reference pixel. A pixel-of-interest value changing unit changes the pixel value of the pixel of interest into the calculated pixel value when the trapping determining unit determines that the pixel of interest is to be subjected to trapping processing.
