Method, apparatus and recording medium for image processing

摘要

When sharpness processing is carried out on image data coded after being decomposed into multiple resolution spaces and attached with sharpness processing information regarding a highest resolution image, appropriate sharpness processing can also be carried out on image data at an intermediate resolution. A coded image file storing data having been coded after being decomposed into multiple resolution spaces is stored in an image server together with information regarding sharpness processing to be carried out on the highest resolution image. Coded image data at an intermediate resolution are read from the coded image file, and decompressed by decompression means to obtain restored image data. Parameter setting means sets a parameter for sharpness processing to be carried out on the restored image data, based on the information and the resolution of the coded image data. Sharpness processing is carried out by sharpness processing means on the restored image data based on the parameter, and the processed image data are reproduced by reproduction means.
