<p>In a video-processing unit comprising a processing means, memory means and a memory manager, the processing means comprises an N-tap digital filter for performing scaling operations on a sampled image present in the memory means. The N-tap digital filter further comprises a predetermined first number of line memories. Each line memory is arranged to contain a predetermined second number of samples of selected lines of the sampled image in the memory means. The second number of samples is smaller than the total number of samples of each line of the sampled image.</p> |
