A reading apparatus includes: a reading unit reading a document; a determination unit determining whether or not inclination correction of a document image is performed based on a shape of a circumscription image which is a circumscribed rectangle of the document image read from the document; and an output unit outputting an image according to a determination result.

The image forming apparatus includes an image reading section and a control section. The image reading section reads a document placed on a contact glass to generate image data. The control section decides whether or not the document is present at a specified position of the contact glass and, upon deciding that the document is present at the specified position, erases handwritten images from the image data of the document read by the image reading section.

An information processing apparatus includes a processor configured to: obtain information about a form of placement of a document placed on a document stage of an apparatus that performs reading of the document by capturing an image of the document stage on which the document is placed; and change a process that is performed in association with reading of the document, in accordance with the form of placement of the document on the document stage.

An image processing apparatus includes a memory, a scanner, and a processor configured to: control the scanner to read an image formed on a sheet along a reading direction, and store data of the read image in the memory, determine a plurality of regions of the image, select one of the regions based on a whiteness or saturation level of color thereof, and add a first image indicating the reading direction to said one of the regions, and store data of the image to which the first image has been added in the memory.

An image processing apparatus includes a processor configured to: extract a first target image corresponding to a reading target having a glossy portion and a non-glossy portion from a first read image acquired by optically reading the reading target in a first reading environment, and extract a second target image corresponding to the reading target from a second read image acquired by optically reading the reading target in a second reading environment in which specular light acquired from the reading target by an image sensor is of higher intensity compared to the first reading environment; execute an alignment of the first target image and the second target image if positions of the first and second target images do not coincide with each other and if the first and second target images are alignable by translating or rotating at least one of the first target image or the second target image; and form a composite image by executing a composition process that composites a non-glossy region corresponding to the non-glossy portion extracted from the first target image with a glossy region corresponding to the glossy portion extracted from the second target image.

An image processing device includes: an obtaining unit that obtains image information of a second region to detect an erecting direction of an image formed on a document, the second region being defined in the image in advance according to a criterion different from a criterion for defining a first region in the image, in which character recognition is performed; and an output unit that outputs character information of the first region, the character information being recognized in accordance with the erecting direction of the image obtained from the image information.

An image forming apparatus includes one or more controllers that control reading of a plurality of documents, an image processing, a printing, and a post-processing, wherein in a case where the post-processing is set, and when a main scanning direction size is alignable to a main scanning direction size of one of the documents by applying, to an image of each document, at least one of image processing among rotation in the unit of 90 degrees, enlargement/reduction, and margin increase/decrease adjustment, the controller allows to perform the post-processing by aligning the main scanning direction size of each image with respect to the alignable size as a reference size.

An image forming apparatus comprises a printer for forming an image on a sheet, an image scanner for reading a measurement image formed on a sheet, and a controller. The printer forms the measurement image at four corners of the sheet. The image scanner reads the sheet on which the measurement image is formed by dividing into two parts. The controller generates an entire read image of the sheet from the read image of the measurement image which is read by the image scanner by dividing into two parts. The controller generates an adjustment condition to adjust a position of an image formed by the printer based on the entire read image of the sheet. The controller causes the printer to form the image based on the adjustment condition.

Provided is an image forming device that performs additional printing, including: an image forming unit that prints an additional image on a transfer medium; a storage that stores information about an alignment image printed on the transfer medium; a reader unit that reads the alignment image printed on the transfer medium on an upstream side of the transfer direction of the transfer medium in the image forming unit; and a control unit that detects and distinguishes multiple alignment images upon reception of reading results from the reader unit. The control unit performs control of storing adjustment information for adjusting the position of the additional image to be formed, according to multiple alignment images, in the storage.

An image reading system includes an image reading apparatus including a transport unit configured to transport a document from a bundle of cut documents one by one, a reading unit configured to read an image of the transported document, and a reading control unit, and an external control unit included in an external device coupled to the image reading apparatus, wherein an inclination correction process that corrects an inclination of the image of the document, a size determination process that determines a size of the image as a standard for the bundle of documents, and a size correction process that corrects the size of the image of the document to a specific size determined by the size determination process are performed.
