The second dither matrix is configured of a plurality of sub-dither matrices. Each sub-dither matrix has a plurality of elements each assigned with a threshold value in a range from a maximum threshold value to a minimum threshold value. A set of threshold values from the minimum threshold value to a predetermined intermediate threshold value is assigned to elements in corresponding locations of each of the plurality of sub-dither matrices."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image processor and image processing method employing a dither pattern having sub-dither patterns","description":"An image processor includes a first dither data memory storing a first dither matrix, a second dither data memory storing a second dither matrix, a selecting unit selecting one of the first dither mat","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8471864","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.
