  • Patent number: 10187536
    Abstract: A processor randomly selects a page image group corresponding to a predetermined number of pages, such as five pages, from scan images of all the pages of a book, and clips a predetermined area (evaluation area) from each of the selected page images. Subsequently, the processor performs, on each clipped image, color correction and compression at a compression rate in accordance with an image quality specified via a user interface, and derives the data volume of each clipped image subjected to the processing. In addition, based on the data volumes of the clipped images subjected to the processing, the processor derives estimated one page data volumes. Then, by using the estimated one page data volumes, the processor derives an estimated data volume of a digital book corresponding to the total pages of the book.

    Abstract: An image-reading device images each page of a book as a basic image and cuts out a predetermined area of the basic image. The device includes an initial-parameter specification unit, a final-parameter specification unit, a determination unit and a correction unit. The initial-parameter specification unit specifies a parameter for the predetermined area of a page around beginning of turning pages. The final-parameter specification unit specifies a parameter for the predetermined area of a page around an end of turning pages. The determination unit determines a parameter for a certain page of the book on the basis of the parameters specified by the initial-parameter specification unit and the final-parameter specification unit. The correction unit corrects an image of the certain page on the basis of the parameter determined by the determination unit.

  • Patent number: 9013759
    Abstract: A document reading unit included in an image forming apparatus and operated with a method of detecting an original document, includes an original document table, a moving irradiation unit having multiple block light sources moving in a sub scanning direction while irradiating the original document, an image sensor receiving reflected light, and a controller that starts a length specifying operation with the moving irradiation unit located at a position facing the original document, sequentially turns on the block light sources, obtains an amount of reflected light under lighting conditions of each block light sources, and determines the length of the original document in the main scanning direction. While the moving irradiation unit is moving in the sub scanning direction, the image sensor receives the reflected light on a region of the original document in the sub scanning direction under each lighting condition during the length specifying operation.

  • Patent number: 9007665
    Abstract: Documents in a large-format scanning system are scanned by coarsely recognizing longitudinal or transverse transition regions between a reflector roller and a document by the substeps of dividing the scanning image transversely into uniform image strips, determining statistical parameters for each image strip, examining the scanning image in the image strips with fixed threshold values for deviations such that, if a value of one the statistical parameters of an image strip exceeds the threshold value, this region is recognized as being a transverse transition region between the reflector roller and the document, and examining the image strips to determine the longitudinal transition region by line-by-line generation of an average value and determining sufficiently strong and steep edges, the image strips being rotated incrementally from the transverse of the document to an acute angle.

  • Patent number: 9001391
    Abstract: An image reading device includes a transporter transporting a document to a reading position, a first corrector correcting a skew of the document by coming into contact with a leading edge thereof, a radiating unit radiating light to the document, an image-information acquiring unit acquiring image information of the document based on information of light reflected therefrom, a reflector reflecting the radiated light, a leading-edge detector comparing a quantity of light reflected by the reflector with a quantity of light reflected by the document so as to detect the leading edge, a skew-amount calculator calculating a skew amount of the leading edge, and a second corrector correcting a skew of the image information based on the skew amount. The device switches between the skew correction by the first corrector and the skew correction by the second corrector based on document information, the skew amount, or user's selection.

  • Patent number: 9001338
    Abstract: An apparatus includes an acquisition unit and a controller. The acquisition unit is configured to, in a case of a recording medium having different thicknesses along a direction crossing a feeding direction in which the recording medium is fed by a feeding unit, acquire correction information that is set on the basis of an orientation of the recording medium in a case where the recording medium is fed by the feeding unit. The controller is configured to move a print start position of a print unit in the direction crossing the feeding direction on the basis of the correction information acquired by the acquisition unit.

  • Patent number: 8988743
    Abstract: According to one embodiment, a document detecting apparatus includes a light-emitting element, a photoelectric conversion element, a light-emission controller and a detection processor. The light-emitting element projects light onto a detection position of a document. The light-emitting element is not used for reading an image of the document. The photoelectric conversion element converts light projected onto the detection position into an electric signal and outputs the electric signal. The light-emission controller changes the light quantity of the light emitted by the light-emitting element during a predetermined interval. The detection processor detects the presence or absence of the document at the detection position of the document based on whether a value of the output electric signal during the predetermined interval changes in correspondence to the change of the light quantity caused by the light-emission controller.
