In order to realize fast, high quality enlargement of image, this paper introduces a new approach to achieve the highorderinterpolation and realize the enlargement of images by means of hardware.
为了能高速、高质量地进行图像放大，提出了一种以硬件方法完成高阶图像插值运算来实现图像放大的新方法。

Therefore the authors put forward a calibration algorithm based on the grid image, which USES subdivision interpolation to approach the deformation and get a result of high-orderinterpolation.
The interpolation algorithm in some way describe the relationship between the data points, carrying out high-orderinterpolation would appear inconsistent with the original function of the phenomenon;
