    Abstract: This image reading apparatus includes an image reading unit, an average-density calculation unit, a statistical processing unit, and a blank-page determination unit. The image reading unit reads an original image and outputs image data of the original image. The average-density calculation unit calculates an average density value of block image data for a plurality of block images, which are obtained by dividing the original image, based on the image data output from the image reading unit. The statistical processing unit determines a characteristic value of the average density value distribution associated with the block images. The blank-page determination unit determines whether or not the original image is a blank image based on the characteristic value determined by the statistical processing unit.

    Abstract: An image processing device includes a mode instruction information obtaining section, a color determination threshold storage section, a mode determination section, and an automatic color determination threshold adjustment section. The mode determination section, using a color determination threshold, determines a mode to be a color mode when the image data belongs to a color mode range, and determines the mode to be a monochrome mode when the image data belongs to a monochrome mode range. The automatic color determination threshold adjustment section adjusts the color determination threshold so as to widen a mode range corresponding to the mode determined by the mode determination section, when the mode indicated by the instruction information obtained by the mode instruction information obtaining section is different from the mode determined by the mode determination section.

    Abstract: An image forming apparatus includes a punch hole detection section, a position calculating section, an image adding section, and an image forming section. The punch hole detection section analyzes image data of a scan image obtained through scanning of an original document to detect two punch hole images. The position calculating section calculates a midpoint between the two punch hole images in the scan image when the two punch hole images are detected. The image adding section adds image data of a midpoint indicating image to the image data of the scan image so that the midpoint indicating image is added to the scan image at a position corresponding to the midpoint. The image forming section performs image formation on a sheet based on the image data of the scan image to which the image data of the midpoint indicating image has been added.

    Abstract: An image forming apparatus includes a determination section, acquisition section, generation section, notification section, and a management section. The determination section determines, when receiving a print job from a predetermined terminal apparatus via a network, whether or not the print job is a private print job. If the print job is a private print job, the acquisition section acquires, from another image forming apparatus coupled to the image forming apparatus to communicate with the image forming apparatus, information regarding the another image forming apparatus. The generation section generates a one time password on the basis of the acquired information. The notification section notifies the terminal apparatus of the generated one time password. The management section manages the generated one time password in association with the private print job and, when receiving the one time password from a user, executes the private print job associated with the one time password.
