    • An original comprises a first page and a second page as disposed face-down on the platen surface of an image-processing device. The platen is scanned to form a platen image. The positions of two diagonally-opposite corners of the original are determined based on a fixed platen reference point. An original image is formed by cropping the platen image based on the positions of the two original corners. The size and position of either one selected page or both pages are determined based on the two original corner positions. When the image of only one selected page is desired, the image of the selected page is formed by cropping the original image based on the size and position of the selected page. When the images of both pages are desired, the images of both pages are formed by cropping the original image based on the sizes and positions of both pages.

    • An image processing apparatus and method include a plurality of different background suppression data acquisition modes selectable by a user in order to obtain background suppression data from a document being reproduced. The obtained background suppression data is used by an image processing unit to suppress the background region of the document being reproduced. The user is able to select one of the plurality of background suppression data acquisition modes depending upon the user's desire for high speed document reproduction versus the required quality of background suppression. In this manner, the user is able to determine whether document reproduction speed or background suppression quality is to be emphasized. The user's choice of a background suppression data acquisition mode is selectively overridden if the image processing apparatus determines that a more performance-intensive background suppression data acquisition mode may be implemented to improve background suppression quality without an associated loss of document reproduction speed.
    • 图像处理装置和方法包括由用户选择的多个不同的背景抑制数据获取模式,以便从被再现的文档中获得背景抑制数据。 所获得的背景抑制数据由图像处理单元使用以抑制被再现的文档的背景区域。 用户能够根据用户对高速文档再现的需求与所需的背景抑制质量来选择多个背景抑制数据获取模式中的一个。 以这种方式,用户能够确定文档再现速度或背景抑制质量是否被强调。 如果图像处理装置确定可以实现更高性能密集的背景抑制数据获取模式以改善背景抑制质量而没有文档再现速度的相关联的丢失,则用户选择背景抑制数据获取模式被选择性地覆盖。

    • A system electronically registers an image on an input document. The system includes a scanner for generating an image data stream representing an electronic image of the image on the input document and an edge detecting circuit for detecting edge data within the image data stream. A circuit detects a first corner of a leading edge of the input document based on the detected edge data and for establishing a first coordinate value therefrom and a second corner of a leading edge of the input document based on the detected edge data and for establishing a second coordinate value therefrom. The system further determines a minimum and maximum location for a leading edge of the scanned document and determines a minimum and maximum location for a trailing edge of the scanned document. An image window is generated representing valid image data to processed and rendered based on the minimum and maximum location for a leading edge of the scanned document, the minimum and maximum location for a trailing edge of the scanned document, the first coordinate value, and the second coordinate value.
