Image processing device for scaling an image with compensation of lattice noise artifacts

摘要

An image processing device for scaling a digital image comprises a lattice noise estimating section (5) for estimating a lattice noise occurrence rate in an output image; and a pre-blurring process section (6) for performing a pre-blurring process with strength that has been determined in accordance with the lattice noise occurrence rate estimated by the lattice noise estimating section (5).
