An image formation system includes a medium-pattern-information-read-unit that reads pattern information of a surface of a medium; a pattern-information-image-creation-unit that creates a pattern Information image based on the read pattern information; and a print unit that adds the pattern information image to a print image to be printed on the surface of the medium and prints the print image on the medium.

Image formation system adding pattern information to print image based on read pattern information from medium surface for determining if medium is original

An image forming apparatus includes a paper fiber reading unit that reads fiber properties of a paper sheet; an encryption unit that encrypts at least a part of an input image based on the fiber properties read by the paper fiber reading unit; and a printing unit that prints an encrypted image portion encrypted by the encryption unit and an image including information representing the fiber properties read by the paper fiber reading unit on the paper sheet whose fiber properties are read by the paper fiber reading unit.

Encrypting image data based on paper fiber properties, printing encrypted image, and decrypting encrypted image

An image reading apparatus including: a paper supply section; a transporting path for transporting a document supplied from the paper supply section; a first sensor which reads an image on a first surface of the document from one side of the transporting path; a second sensor which reads an image on a second surface of the document from the other side of the transporting path; and an image processing section which is constituted so as to correspond to a first reading mode in which two sides of the document are read using the first sensor plural times, and a second reading mode in which two sides of the document are read using the first sensor and the second sensor, and which makes a registration position and direction of an output image in both the first and second reading mode the same.

Image reading apparatus, image processing system and registration method in two-side image reading

The invention provides an image reading apparatus includes a feeder that feeds a sheet, a transfer path on which the sheet fed by the feeder is transferred, a first reading unit that captures a first image on a first face of the sheet from one side of the transfer path to obtain first image data, a second reading unit that captures a second image on a second face of the sheet from the other side of the transfer path to obtain second image data, and a correction unit that substantially equalizes image density of the first image data and that of the second image data in a case where the first image and the second image are captured at a single transfer of the sheet through the transfer path.

Image reading apparatus for correcting images on both sides of a document sheet

An image reading apparatus includes: a light source that irradiates a document; a sensor that receives reflection light reflected from the document; a reference member that is read by the sensor; and an abnormal site detection unit that detects, using first reading data acquired by reading the reference member according to a first reading condition set to the light source or the sensor and second reading data acquired by reading the reference member according to a second reading condition, which is different from the first reading condition, set to the light source or the sensor, abnormal sites in the first reading data or the second reading data.

Image reading apparatus and reference member foreign matter detecting method

An image processing apparatus has an extracting unit, a dividing unit and a text searching unit. The extracting unit extracts a text part from an image. The dividing unit classifies text in the text part based on color information of the text. The text searching unit searches the text based on the color information.
