Abstract: An image processing apparatus includes a mounting information holding circuit, an abnormality determination circuit, and a mounting execution circuit. The abnormality determination circuit determines whether or not a predetermined abnormality determination condition is met based on mounting information related to already-executed mounting held in the mounting information holding circuit when a hard disk drive is inaccessible. The mounting execution circuit sets a power supply of the hard disk drive in ON state after once setting in OFF state, and then executes mounting of the hard disk drive after the setting in ON state when the abnormality determination circuit determines that the abnormality determination condition is not met.

Abstract: An original reading apparatus includes an original tray. A conveyance unit conveys an original of an original bundle on the original tray. A reading unit reads the original conveyed. A first detection unit detects a first length of the original in a principal scanning direction. A second detection unit detects a second length of the original bundle in an auxiliary scanning direction. A third detection unit detects the original conveyed. A prediction unit predicts an original size by selecting from candidates corresponding to the first length in a first prediction mode, or by determining based on the first and second lengths in a second prediction mode. A specifying unit specifies the original size based on the first length and a length in the auxiliary scanning direction detected by the third detection unit. A change unit changes the prediction mode when the predicted original size differs from the specified original size.

Abstract: In an image processing apparatus, a specific local gradation pattern detecting unit detects a specific local gradation pattern in a density distribution of a pixel array in a secondary scanning direction at each one of plural sampling positions along a primary scanning direction in a document image. A crease detecting unit detects a crease on the basis of positions in the primary scanning direction and positions in the secondary scanning direction of plural specific local gradation patterns detected for the plural sampling positions along the primary scanning direction. A crease removing unit removes the detected crease. The specific local gradation pattern has a density distribution that monotonically increases from a background density to a local peak density and monotonically decreases from the local peak density to the background density in the secondary scanning direction.

Abstract: A printing system receives a graphic document having a security area. The graphic document identifies a secure color to print in the security area. The graphic document is converted for printing by a printing engine of the printing system. This converting substitutes a secure patterned color in place of the secure color. The specific printing engine prints the printing bitmap to output a printed version of the graphic document with the secure patterned color in the security area. The security area of the printed version of the graphic document has a color appearance, and the secure color does not identify the type of security feature within the secure patterned color.

Abstract: A method and system for automatic correction of skewing of digital images. A captured digital image s provided. An initial angle of rotation is determined by sampling test angles of rotation of the input image and analyzing resultant rotated images to determine a resultant rotated image with a highest number of substantially empty lines.

The aggregated slope is converted to the refining angle of rotation. The first rotated image is rotated by the refining angle of rotation to result in a final rotated image.
