Abstract An improved image processing system (204, 205B, 205E, 206, 207) involves decoding compressed image data including frequency domain coefficients defining blocks of pixel values representing an image at a first resolution to provide an image at a reduced second resolution for display from a selected sub-set of the frequency domain coefficients. The apparatus includes an enhanced motion-compensation-unit (MCU) (208) operating with blocks of pixel values representing an image at an intermediate third resolution lower than the first resolution but higher than the reduced second resolution.
