The type of a medium for printing is specified by a user; density correction information acquired at the most up-to-date time for each chromatic color ink available for the medium of that type is read from the memory; it is determined whether or not the most up-to-date time when the density correction information is acquired for each of the chromatic color inks available for the specified medium is the same time; if the most up-to-date times are the same, density correction is performed on image data, using a correction table that corresponds to the density correction information acquired at the most up-to-date time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image correction system and image correction method","description":"Every time density correction information corresponding to a colorimetric value of a patch is acquired, the time when the density correction information is acquired and the type of a printing medium o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8474942","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.
