Abstract

Circuitry configured to generate an ROI mask by determining whether each of quantized wavelet coefficients constituting quantized image data is associated with an ROI or a non-ROI in an original image on the basis of the scaling amount of the Max-shift method, generate first image data by performing inverse quantization on the quantized image data after being scaled down, generate second image data having a specified decomposition level by performing inverse wavelet transformation on the first image data, generate a restored ROI mask having the same decomposition level as that of the second image data by performing a predetermined process on the ROI mask once or a plurality of times, generate masked image data by applying the restored ROI mask to the second image data, and perform the inverse wavelet transformation on the masked image data until a decomposition level becomes zero.
