The optical navigation device is located on a surface. The step (d) comprises: collecting reference images of different parts of the surface for a plurality of combinations of moving directions of the optical navigation device and placement directions of the surface; and determining a type of the surface via comparing images of a current surface with the reference images."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image quality improving method, optical navigation device control method, and optical navigation device using the methods","description":"An optical navigation device control method comprising: (a) computing brightness contrast information of original images captured by an image sensor of an optical navigation device; (b) computing brig","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11947737","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.
