1. Method for processing digital image data, comprising: (a) a step (SI) of providing digital image data (ID) to be processed as input data (inpD), said digital image data (ID) being representative for at least one of an image (I), a sequence of images (SI) and a video (V), (b) a step (S 2 ) of processing said input data (inpD), thereby generating processed image data (procID) as processed data (procD), said processed image data (procID) being representative for an respective one of a processed image (procI), a processed sequence of images (procSI) and a processed video (procV), said processed image (procI), a processed sequence of images (procSI) and a processed video (procV), having enhanced sharpness properties, and (c) a step (S 3 ) of providing said process data (procD) as output data (outD), wherein said step (S 2 ) of processing said input data (inpD) comprises a process of detecting and enhancing edges (DEE) and uses a multi rate signal processing, multi resolution signal processing and/or multi scale signal processing with respect to said input data (inpD) in order to realize the multi rate, multi resolution and/or multi scale sharpness enhancement with respect to said input data (inpD).
