    • 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.
    • 提供了一种基于低通滤波的图像插值装置和方法。 该装置包括边缘方向检测器,用于检测像素之中最接近待插入像素的像素的边缘方向,并确定待插值像素的边缘方向作为检测到的边缘方向;像素值计算器计算像素 通过使用位于与内插点相邻的像素的像素值,位于具有预定尺寸的格子滤波窗口中的内插点的值;以及滤波单元,根据对应的低通滤波器对待定位的像素执行低通滤波 对于待内插像素的确定的边缘方向,低通滤波器分别对应于预定的垂直,水平,左对角线和右对角线方向之一的低通滤波器之一。 因此,可以简化计算待内插像素的像素值的处理,并且可以提高处理速度。 此外,即使对于具有不均匀边缘的区域,也可以获得高质量的图像而不具有像素值的误差引起的诸如阻塞效果的图像劣化。
