Abstract: The pages of a book being held at least partially open may be sequentially automatically turned over from one side of the book to the other by pivoting an elongated arm from one side of the book toward the other and turning over individual pages with a vacuum head pivoting relative to the elongated pivoted arm about a different pivot axis as the elongated arm moves to reduce undesirable forces on the individual book pages being turned over. The vacuum head may initially pivot to bend the edge of an individual page up away from the book, to aid in page separation, and then subsequently differently pivot to help peel the same page gently away from the vacuum head and flip it over onto the opposite side of the book. This may be assisted by moving frictional belts on the vacuum head.

Abstract: An image processing device and method recognizing and deleting extraneous objects in image for data based on analysis of the image data. An object detection means detects an object region such as a finger or the like in a document image, and an image processing means erases part of an image corresponding to the object region of a finger or the like in the image data. The object detection means detects the object region by a dynamic contouring method in which a specific initial contour is set relative to the image data, and the initial contour is adjusted along a border of variable density in the image data so as to accurately erase an object image of a finger of a user holding a document.

Abstract: An image reading apparatus is disclosed which reads from above a book document mounted as opened upwardly. This image reading apparatus decides the positions of face terminal parts of the document by detecting longitudinal edges in accordance with differences in luminance contrasts which occur in the face part of document and the lateral face part of document in the lateral direction of an image and further detecting the pattern of longitudinal edges due to the overlap of pages in the lateral face part of document and the amount of change of the position of the upper side edge of the document. The apparatus, therefore, is capable of accurately detecting the face of the document and the lateral face of the document and producing exclusively the image of the face of the document in spite of the presence of an index, a pattern of black frame, or a black background in the terminal parts of the face of the document.

Abstract: The present invention pertains to a book scanner that reads the image of an document such as a book or magazine while it is placed open and face up, and more particularly, to an image reader that detects the height distribution of the document prior to performing a pre-scanning to detect the size of the document and the background luminance of the document. Thus, a focal length adjustment is performed in response to the detected height distribution while the pre-scanning takes place in order to prevent defocusing caused by the curvature of the document consisting of an open book or magazine. The book reader also reads the book in at least two spectral regions to detect and eliminate image anomalies.

Abstract: An image reader capable of outputting excellent quality read images, without illumination irregularities, similar to that of flat documents even when the document surface is curved as in the case of book-like documents. An image reader provided with a memory to store correction data to correct differences of illumination of each pixel of a document image, and which corrects the read information of each pixel in a document image using correction data corresponding to the measured height of a document surface among correction data stored in the memory. For one aspect, this image reader is constructed so as to correct a group of read information corresponding to a set of pixels arrayed in one direction by excluding specific frequencies among the illumination distribution from the set.

Abstract: An image reading device capable of preventing, by increasing the quantity of light at the center or bound portion of a spread book document, the quantity of light from becoming short and preventing density from becoming irregular due to the deviation of a focus. At and around the center of a spread book document where the document is bound, the quantity of light for illumination or the amplification gain of image data read from the document is increased. A plurality of fluorescent lamps illuminate the surface of the document at the upstream side and downstream side with respect to an intended scanning direction. When the edge of the document is to be detected, only one of the lamps is turned on to enhance the stripe pattern representative of the stepped edge portion of the document.

Abstract: An image of the original document is read rapidly to effect quick production of the first copy even when the function of the shading correction and the function of the color/monochrome judgment operate. A waiting position P2 of a first slider 211 is located on the opposite side from a scan starting position P3 in reference to a reading area for the original document, and a location of a shading correction plate 206 is interposed between the reading area for the original document and the waiting position P2 of the first slider 211. While the first slider 211 is in the process of returning from the waiting position P2 to the scan starting position P3 for the preparation of reading the image of the original, a shading correction and a color/monochrome judgment are carried out for preventing the first slider 211 from having extra motion.
