摘要： A method and an apparatus to correct the length of an image in a flatten scanner. The method includes moving an image sensor by driving a motor; calculating a first number of pixels; calculating a difference between the first number of pixels and a second number of pixels; and correcting the length of the image scanned in the flatten scanner by using the calculated difference. Therefore, the method makes it possible that a scanned image can have the same length as that of an original image by using the difference between the first and second numbers of pixels. In addition, when a flatten scanner is developed, necessity for fine adjustment to correct the length of a scanned image is eliminated, and, therefore, time required to develop a scanner is shortened.

The pre-filtering path includes a first path sending a raw image data to the data compressor via the filter and a second path passing the image data expanded. The post-filtering path includes a third path passing the raw image data to the data compressor and a fourth path sending the image data expanded to the filter.

摘要： A first signal and a second signal are obtained using a first and second image sensors, respectively. The first signal and the second signal are converted from analog to digital form. The first signal and the second signal are then averaged to improve the signal to noise ratio of the resulting signal. The first signal may be obtained using a channel corresponding to a first channel. The second signal may be obtained using a channel corresponding to a second channel. Further, a third signal may also be obtained using a channel corresponding to a third channel. Then, the first, second, and third signals may be averaged to generate an averaged signal.

摘要： A method for printing a human-readable document from a composite image data file is disclosed. The method comprises obtaining a scanned image of the composite printed document to extract a spatial pattern of the document and other image property information. Next, the machine-readable content in the composite image is decoded to obtain reference information describing nominal spatial relationships of the human-readable and machine-readable content. The method then compares observed spatial relationships with reference spatial relationships to obtain a spatial deviation value. The spatial deviation value is then applied to the scanned image, and then a corrected image is outputted.

摘要： The invention provides a procedure that is applicable to various halftoning methods, which minimizes image distortion introduced by the halftoning process. The procedure involves maintaining specific relationships between the halftone pattern and the phase and resolution of the input image. Specifically, that the halftone pattern is designed such that it does not bias tone reproduction with respect to the location of the input image pixelsnulleach input pixel should be given equal weight when filtered by the halftoning process. This suggests a 1 to 1 relationship between each pixel of the input image and the corresponding tone output produced by the halftoning process. The procedure results in improved print quality, manifested by avoidance of certain types of moirnull which are commonly associated with halftoning, as well as improved reproduction of edges and image details.

摘要： When a halftone dot image structure reproduction mode is selected in a proof image data generating apparatus, color image data are generated using threshold matrixes having respective screen angles which are essentially equal to the screen angles of printing plates for a color print and screen ruling ratios between the threshold matrixes which are essentially equal to the screen ruling ratios between the printing plates for the color print, and the processed color image data are supplied to a color printer. The color printer outputs a color proof having a rosette pattern similar to the rosette pattern in the color print based on the supplied color image data.

摘要： A method and a system for de-screening an image signal. The system comprises a filter bank, a control module and a blend module. The filter bank filters the image signal and produces a set of filter output signals. The control module generates at least one control signal based on the image signal and some of the filter output signals. The blend module dynamically blends the filter output signals in accordance with the control signal to produce a de-screened output signal.
