    摘要： An image reading apparatus that makes it possible to reduce the influences of dirt on a white reference chart itself, stripes caused by dust, and the like, and thereby generate accurate data for shading correction. An image processor performs shading correction on image data read by a reader unit. The read image data is compared with threshold values set for each pixel, and a pixel which is out of a range of the threshold values is determined as a singular point pixel. Data of a pixel determined as a singular point pixel is interpolated from data around the singular point pixel. Data of a pixel which is not determined as a singular point pixel is adopted as valid shading correction data. An operation controller controls the number of effective sampling lines from start to termination of sampling to be performed.

    摘要： A disclosed image scanning device includes a pressing unit for pressing a document; an operation detection unit for detecting an opening operation and a closing operation of the pressing unit; a movable scanning unit for scanning the document; and a control unit for moving the movable scanning unit from a standby position to a document-size detection start position when the opening operation is detected and moving the movable scanning unit from the document-size detection start position to the standby position to determine a size of the document when the closing operation is detected. The control unit is configured to continue moving the movable scanning unit from the standby position to the document-size detection start position until the arrival of the movable scanning unit at the document-size detection start position is detected even if the pressing unit is operated.

    摘要： The image forming apparatus comprises an image reading device that reads a manuscript and generating a manuscript image data, and a command input device that inputs a command. A layout analysis device is provided for analyzing a layout of an image expressed by the manuscript image data. A controller is provided which, when a command is inputted trough the command input device, decides a page order for horizontally or vertically juxtaposed pages based on a result of analysis by the layout analysis device. An image splitting device generates split image data expressing two horizontally or vertically split images of the manuscript image data, and outputs the split image data in accordance with the order that is decided by the controller.

    摘要： A variable reflectance cover for a scanning system. The cover comprises a backing moveable through a plurality of positions. Moving the backing through the plurality of positions varies the reflectance of the cover. In one embodiment, the backing is an endless rotatable belt. In a second embodiment, the backing is a removable panel having a first side with a first reflectance and a second side with a second reflectance. In yet a third embodiment, the backing includes polarizers placed adjacent to a reflective panel. Rotating one polarizer relative to another varies the reflectance of the cover. In another embodiment, magnetic louvers are provided for changing the reflectivity of the cover.
