The present invention relates to an image acquisition and reproduction system considering super-resolution interpolation of acquired images. By providing an aliasing control filter for controlling aliasing artifacts rather than removing them, an improved image quality is achieved while leaving the option for reconstructing high-resolution images by means of super-resolution interpolation techniques. A preferred embodiment of the present invention relates to hierarchical video data compression and decompression with improved coding efficiency. The video data is encoded into two bitstreams. The first bitstream is a self-contained representation of a low-resolution version of the video data. The second bitstream only contains the difference between the full-resolution video data and its super-resolution reconstruction. |
