Abstract
A compressed image, for which a desired SSIM value is obtained, is acquired when irreversible compression is performed. Specifically, a quadratic curve Gis defined. Next, a compression ratio Pis calculated. An image is irreversibly compressed at the compression ratio P, the compressed image is decoded and an SSIM value Sis calculated. If the calculated SSIM value Sis outside an allowable range of the target SSIM value, then the quadratic curve Gis corrected in such a manner that it will pass through an intersection Cbetween the compression ratio Pand the SSIM value S, whereby a quadratic curve Gis obtained.
