Abstract: This invention provides a flat-bed scanner capable of scanning a thick book without any distortion at the protruding binding edge. The scanning window forms an obtuse angle with the frame of the scanner supporting the scanning window. The obtuse angle allows the binding edge of the book to rest snugly over the window. The slanted structure of the frame also makes room for the image reading head to scan to the very edge of the page of the document.

Abstract: A portable image scanner capable of selecting a manual document loading mode in which a cover member is united to a scanner body to feed a cut-sheet document through a document passage defined between the united scanner body and cover member for scanning the document, or a self-propelling mode in which the cover member is separated from the scanner body to move the independent scanner body on a thick document such as a book. The scanner body has a document sensor for detecting the cut-sheet document placed in the document passage in the manual document loading mode, and the thick document in the self-propelling mode to prevent the scanner body moving on the document from falling out of the edge of the thick document.

Abstract: An image reading apparatus for reading a document such as book, constructed to detect a height of the document. A line sensor captures an image of the document and a lateral side view of the document reflected on a mirror. Then the height of the document detected by the line sensor is corrected based on a deviation between a positions of the document image projected on the line sensor and the lateral side view of the document projected on the line sensor.

Abstract: In an image reading apparatus, a spot-light position calculator calculates a distance between a document original and a solid state imaging device using the output signals of a light sensing device, which receives a reflected spot light from the original. A image reading section is moved to a read position according to the calculation results, by a drive mechanism. Thereafter, the original is read. A distorted-image processor extends the data on the image on the undulated portion of the original and corrects the density of the extended image data. The data extension and the density adjustment are performed on the basis of the calculation results from the spot-light position calculator.

Abstract: The present invention is a novel book scanner that employs 2-dimensional array detectors attached, either rigidly or rotatably, at a common edge and disposed in a wedge shaped manner. The opposite edges of the arrays are housed in a base portion. The base portion additionally supports backlight to provide the necessary illumination of the book pages and the read-out electronics which output the image data stored in the detectors to other processing units that may use such data.

Abstract: An image reading apparatus includes a carrying unit for carrying a sheet original and a book original to a reading position, an original urging member including a reference member, closed when a sheet original is carried by the carrying unit and opened when a book original is carried by the carrying member, a reading unit for reading an image of an original carried to the reading position and the reference member of the original urging member in a closed state, and a correcting unit for correcting nonuniformity of an image signal obtained by reading an original image on the basis of a reference signal obtained by reading the reference number. When the original urging member is open, the correcting unit corrects nonuniformity of an image signal on the basis of the reference signal used upon reading of a previous original image.

Abstract: A document reading apparatus comprising a document table, a reading section disposed above the document table for reading a document, e.g. an opened book, placed on the document table, and a linear light source for emitting light to the opened book at an angle thereto. The reading section includes a sensor for detecting an image of the light emitted to the book. This image displays a brightness distribution over surfaces of the opened book including curvatures adjacent the joint. The brightness distribution is used as a reference for rectifying an image signal corresponding to the opened book when the document image is reproduced.

Abstract: To specify a contour to be detected even when there are a plurality of candidates of the contour on the periphery of a photographing target, an image processing apparatus comprises: a determining unit which detects a plurality of candidate points being the candidates of the contour of a subject based on distance image information of the subject in an image, and determines an inspection-target area in the image based on the detected candidate points; and a specifying unit which detects line segments existing in the inspection-target area determined by the determining unit, based on luminance information of the inspection-target area, and specifies the line segment being the contour of the subject based on the candidate point from the detected line segments.

Abstract: An image reading device includes a shooting unit, a light source unit, a shooting controller, and a combining unit. The light source unit sequentially irradiates the bound document with light from first and second irradiation positions opposing each other with respect to a first straight line orthogonal to a direction of a binding portion of the document. The shooting controller controls the shooting unit to shoot a first region positioned at the second irradiation position side on the document when the light source unit irradiates the document with light from the first irradiation position, and controls the shooting unit to shoot a second region containing a region other than the first region on the document when the light source unit irradiates the document with light from the second irradiation position. The combining unit combines a shot image of the first region and a shot image of the second region.
