A compression processing unit (3) performs a lossy compression process using frequency conversion for the luma plane and the chroma planes after the offset process performed by the offset calculating unit (2). Further, a decompression processing unit (4) decompresses compressed data generated in the compression process performed by the compression processing unit (3) to a luma plane and chroma planes. An inverse offset calculating unit (5) performs an inverse offset process for a plane for which the offset process has been performed among the luma plane and the chroma planes after decompression by the decompression processing unit (4) where the inverse offset process expands a pixel value range by the offset."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image compressing/decompressing apparatus and image forming apparatus","description":"An offset calculating unit (2) performs an offset process for a luma plane and/or chroma planes where the offset process compresses a pixel value range by a predetermined offset except for a saturatio","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9596478","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
