    摘要: An apparatus and method for image interpolation based on low pass filtering are provided. The apparatus includes an edge direction detector detecting an edge direction for a pixel nearest to a to-be-interpolated pixel among pixels and determining the edge direction of the to-be-interpolated pixel as the detected edge direction, a pixel value calculator calculating pixel values of interpolation points located in a lattice filtering window having a predetermined size by using pixel values of pixels located adjacent to the interpolation points, and a filtering unit performing low pass filtering on the to-be-located pixel according to a low pass filter corresponding to the determined edge direction of the to-be-interpolated pixel, the low pass filter being one of low pass filters corresponding to predetermined vertical, horizontal, left diagonal and right diagonal directions respectively. Accordingly, a process of calculating the pixel value of the to-be-interpolated pixel can be simplified and a processing speed can be increased. Furthermore, it is possible to obtain a high-quality image without having image deterioration such as blocking effect caused by an error in a pixel value even for a region with an uneven edge.

    摘要: Disclosed is an apparatus for sensing the feeding of individual sheets of paper in which the feeding of two or more overlapping sheets can be detected in a sheet feeding apparatus for continuously transferring sheets of paper one by one along a predetermined paper traveling path. The apparatus employs a support plate which allows the sheets of paper to slide, and a contact arm adapted to contact the support plate and to be moved upward by a height corresponding to the thickness of the sheet of paper when the sheet of paper passes between the support plate and the contact arm, instead of using an expensive rollers, bearings or the like as a means for sensing the thickness of a sheet of paper being fed. Accordingly, the rotational angle of the contact arm enables the thickness of a sheet of paper being fed to be sensed, so that the feeding of two or more overlapping sheets of paper between a driving roller and a driven roller is always detected correctly and reliably even when foreign matter is stuck to the rollers. Further, the paper feed sensing apparatus has a simple structure and malfunctions less.
