<p>An image processing device in which the storage size for image data inputted from a scanner or an electronic still camera or transmitted through communication means such as the Internet is small, and a clear magnified image can be outputted. To reduce the storage size for the image data, low-frequency components extracting means extracts the low-frequency component in the image data, and encodes the high-frequency component after finding information concerning the low-frequency component. To output a clear magnified image, magnified image frequency estimating means estimates the frequency components necessary for image-magnifying by edge extraction and by nonlinear interpolation. Image magnifying means estimates a magnified image by wavelet conversion.</p> |
