摘要： An image reading apparatus for reading a document (2) such as a book from above with the target faces thereof placed up, which allows correction of distortions of the image, without relying on the background color of the target faces of the document (2), wherein image processing means (8) detects the boundary between the document and the document-guiding means (31) (the document edge (21)) on the basis of the image read by image reading means (5) and corrects distortions of the image with reference to the detected boundary (21).

摘要： A dual image station photoprint scanner comprises a cabinet having an upper, album imaging station (15) and a lower, magazine-fed, platen imaging station (17). The upper imaging station includes a translatable unit having a glass plate upon which a photoprint is placed in a face- down position. Adjacent to the top plate, the translatable cabinet has a sloped support surface, to accommodate a photo album (27). A lower portion of the cabinet contains a platen feed mechanism, which translates a photographic print support platen from a supply magazine to a platen imaging station, and then feeds the platen to a storage magazine. A high resolution CCD image sensor is supported at an image projection plane of a multi-directional image projection mechanism. A digital imagery data recording mechanism is coupled to the image sensor and is operative to record, on a digital data storage medium, a digitized image that has been projected on the image sensor. The multi-directional image projection mechanism comprises an adjustable image magnification device, such as an adjustable focal length, adjustable focus, zoom lens (54), which is operative to controllably vary the size of the image projected onto the image sensor in accordance with the contents of one or more photoprint parameter regions on the platen. The image projection mechanism also includes a controllably rotatable mirror (53) disposed between the top plate and the platen imaging station for selectively providing an optical projection path from one of the imaging stations to the CCD sensor.

摘要： A book edge copying system is enabled by providing a full rate/half rate scanning system 36,38 modified to tilt the system axis so as to move the start of scan location to a point P′ coincident with the book edge location. A full rate mirror, 36 in one embodiment, is tilted at an angle (45 + ½ ϑ)⁰ to the platen perpendicular thereby effectively tilting the system axis by an angle ϑ. The off-axis angle ϑ introduced at the scan mirror 36 is compensated for by appropriate rotation of the projection lens 40 and the image side optical elements 46.
摘要翻译：通过提供修改成倾斜系统轴的全速率/半速率扫描系统36,38以使扫描位置的开始移动到与书边缘位置一致的点P min，来启用书本边缘复制系统。在一个实施例中为36的全速率反射镜以垂直于平台的角度（45 + 1 /2θ）<0°倾斜，从而有效地使系统轴倾斜角度θ。通过投影透镜40和像侧光学元件46的适当旋转来补偿在扫描镜36处引入的离轴角度θ。

摘要： A document is described for scanning a page of a book comprising:-

1. a movable housing having at least one flat face containing a window through which light from a document to be copied can pass.
2. a scanner within the housing adapted to scan an image of the document to generate an electrical video signal corresponding to the information carried by the document, '
3. means for supporting a book face upwards so that the book can be moved into contact with the window,
4. a pivoting joint between the housing and a support therefor to permit rotation of the housing into at least one other position in which the window is unobstructed and light from a remote document can be directed therethrough to from the image to be scanned.
