In the second pixel data group, an orthogonal transformation is performed in several layers using only the predetermined number of coefficients from the lowest frequency side from among the coefficients obtained by the orthogonal transformation. The predetermined number of coefficients from the lowest frequency side from among the coefficients obtained by the orthogonal transformation in the highest layer, and the coefficients that are obtained in a layer other than the highest layer not used for the orthogonal transformation are encoded, thereby generation the compressed data. Accordingly, encoding is performed while separating lower frequency components from higher frequency components."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image compressing apparatus, image compressing method, image decompressing apparatus, and storage medium","description":"In the present invention, a first pixel data group of several pixels existing in block into which an image is divided is divided, thereby generating several second pixel data groups.
