Abstract
In an image data processing system, an insignificant space estimation unit predicts a significant/insignificant space in a high-frequency subband on the basis of a low-frequency subband signal in a wavelet space. A deletion unit deletes data in the insignificant space which is predicted by the insignificant space estimating unit. Here, the data is contained in the high-frequency subband. An error-estimation detection unit detects presence of significant data in the space predicted to be insignificant by the insignificant space estimation unit. An adding unit adds to output data a significance attribute indicating that significant data exists in the space detected by the error-estimation detection unit.
