摘要： A method for removing show-through defects in scanned document images is provided by adjusting the scanner's image sensor calibration gain in the area of a drive roll gap. The method will also compensate for drive roll contamination. The invention uses a modified calibration scheme in conjunction with a document transmission sensor in the document handler to measure radiant energy transmitted through the document, i.e., transmission. The scanner adjusts the calibration gain factors to simulate a uniform background with knowledge of the gap and the input document's transmission thus a uniform scanner response is determined and presented to the image processing. A device for carrying out the method is also provided.

摘要： A first series of control patches is printed with a first marking engine. A second series of control patches is printed with a second marking engine. Relative reflectance values of the patches printed with the first and second marking engines are measured with respective first and second engine response sensors. Based at least on a difference in the measured relative reflectance values of the control patches printed with the first and second marking engines, a relative engine to engine error is determined. The engine to engine error is decomposed into components. Based on the decomposition, adjustment of at least binary values of a digital image is determined so that print density of a first marking engine output substantially matches print density of a second marking engine output.

摘要： Signals from a color (multi-row) full width array sensor are used to detect and correct for motion quality issues in a constant velocity transport or platen document scanner. This capitalizes on the geometry of the full width array sensor, in which three or four rows of photo sites are arranged in the slow scan direction. For example, the arrival time of an image edge of the red sensor row may be compared to the slightly later arrival time at the blue sensor row, and the difference yields the velocity. The velocity can then be fed back to control the transport.

摘要： A photosensitive imaging apparatus has a linear array of groups of photosensors. In a low-resolution scanning mode, all of the photosensors in each group act together as one large photosensor. In a high-resolution scanning mode, each photosensor in a group acts outputs image-based signals independently. In either mode, the signals output by the photosensors are transferred to one of two output lines, such as for “odd-” and “even-” positioned photosensors or groups of photosensors. The signals on the two lines can then be multiplexed to a single output line. The dual output lines enable fast signal output in either resolution mode.

摘要： In a digital reproduction system incorporating a single pass scanner, accurate image processing results from processing a subset of grayscale image data. More specifically, scanlines that correspond to the leading edge of a document are stored and processed to detect skew and to obtain an appropriate correction. The lead edge correction is then applied to the entire grayscale image. Accordingly, the present systems and methods eliminate skew from grayscale images in real-time. The corrected image is rendered to binary and stored in electronic pre-collation memory and cropping, masking and other image editing operations can be performed on the binary image data before the image is printed.

摘要： This invention relates to an imaging device that extends the processing of resources to data having a greater bit-depth. A signal having data at the first bit-depth is received, and at least a portion of the data at the first bit-depth is converted into an estimated value that is at the second bit-depth. A residual that indicates a difference between the data and the estimated value is determined. The estimated value is processed through the resource to form processed data that is at the second bit-depth. The data is then substantially recovered at the first bit-depth from the processed data that is at the second bit-depth and based on the residual.
