    Abstract: A document camera (1) detects a figure of a known shape on a stage (13) and acquires the coordinates of the figure, and acquires image processing area and projection correction parameter. The document camera (1) extracts image data of the image processing area from image data acquired by shooting the stage (13) and an original (4), and performs projection correction on the image data using the projection correction parameter. Further, the document camera (1) performs rotation correction on image data undergone projection correction. Furthermore, the document camera (1) performs zoom correction on image data undergone rotation correction, and generates output input image.

    Abstract: The present invention relates to the use of a camera and a structured light pattern in a platenless document imaging system (1) to capture the image of a page or of a bound book together with depth information that can be inferred from the light pattern. The imaging system (1) comprises a support surface (12) for a document (30) to be imaged, a light stripe projector (4) arranged to project a plurality of diverging sheets of light that extend from the projector (4) towards the support surface (12) for forming a series of stripes across the document (30), a camera (2) having a detector array (22) for capturing an image of the document (30) and of light stripes projected onto the document (30), a processor (25) arranged to receive (23) from the detector array (22) data representative of images of the document (30) and of the light stripes and to calculate therefrom a three-dimensional profile of the document (30) relative to a reference surface, characterised in that the relative divergence of adjacent sheets of light varies laterally across the sheets so that the stripes are concentrated where the divergence is relatively low.

    Abstract: An optical mouse scanner allows users to perform quick scans of paper documents (or of some other surface) without requiring a separate, standalone scanner. Scanning functionality may be provided to an optical mouse, such as a wireless optical mouse. The scanning sensor and/or the scanning light source could be same as that used for the optical motion detection for the mouse. Alternatively, a separate light source and/or imaging element could be provided for purposes of scanning. Image stitching software could use a number of captured images (e.g., a stream of captured frames) alone, or in association with mouse orientation and/or position information, to assemble a larger image from smaller captured image frames.

    Abstract: A reading time setting section (44) determines a read area for an imaging section (25) on the basis of color chart positional data (id). The imaging section (25) reads an image on printing paper during the reading time and readout image data (rd) is stored in an image data storage section (45). A reference mark detecting section (46) detects the positions of reference marks from the readout image data (rd). A color chart actual position calculation section (47) corrects a tilt of a color chart determined from the positions of the reference marks and calculates an actual position of each of color chart fields (cr). An image data readout section (48) reads out image data on a color chart field corresponding to the calculated actual position. At the same time, image data on a white color field immediately above the color chart field is also read out. A white color correction section (49) produces a white reference on the basis of the image data on the white color field and corrects the image data on the color chart field. A color chart information determination section (50) measures color chart information, such as a color density and a dot percentage, about each of the color chart fields. This printing press determines a reading time on the basis of the position of the color chart at the time of printing plate recording and thereby allows imaging of an area including the color chart on the printing paper being transported.

    Abstract: A method for correcting scanning errors in a shuttle type of a scanner, including the steps of scanning a pattern sheet on which pattern data having a specified shape are recorded. Errors for decline of the pattern data are corrected by using the pattern data having a straight line among the scanned pattern data having the specified shape. Then, errors for distance between bands are corrected by using the pattern data having the specified shape among the pattern data of which the errors for decline are corrected. Accordingly, since the errors for decline and the errors for distance between the bands can be corrected by using a computing program, there is an advantage in that correcting the errors of the pattern data is very simple. A further advantage is in that even if the scanner is subjected to an impact from its exterior, correcting the errors for decline and the errors for distance between the bands can be promptly performed.

    Abstract translation: 一种用于校正梭式扫描仪中的扫描误差的方法，包括扫描记录了具有指定形状的图案数据的图案片的步骤。 通过使用具有指定形状的扫描图案数据中具有直线的图案数据来校正图案数据的下降的错误。 然后，通过使用校正了下降误差的图案数据中的具有指定形状的图案数据来校正频带之间的距离误差。 因此，由于可以通过使用计算程序来校正衰减的误差和带间的距离误差，所以存在校正图案数据的误差非常简单的优点。 另一个优点在于，即使扫描仪受到来自其外部的冲击，可以迅速地进行校正下降的误差和带间距离的误差。
