Abstract: PROBLEM TO BE SOLVED: To make improvable the degradation of the picture quality observed and a blur of a sharp edge by selecting an interpolation kernel corresponding to an edge strength index, an edge direction index and an edge context index concerning the discrete sample of a first set. SOLUTION: Image data are accessed, the text area of high contrast is detected and the edge strength and edge arrangement of image data are measured (S100-S110). The detected text domain and edge domain are coupled to a kernel or kernel parameter and a selection map concerning respective input pixels and cleaning is performed (S120 and S125). The edge domain is arranged on a uniformly directed edge domain or smooth background (S130). The cleaned kernel selection map is interpolated by using an NN interpolation kernel, and the kernel selection map or kernel parameter selection map is generated concerning respective output pixels (S135 and S140).
