The distance calculation apparatus includes a distance calculation unit to calculate the distance information by comparing a local region of the first image and a local region of the second image and a confidence calculation unit to calculate confidence of the distance information based on a contrast evaluation value, which is a value indicating a magnitude of a contrast change amount in the local region of the first image, in the local region of the second image, or in a local region of a composite image of the first image and the second image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Distance calculation apparatus, imaging apparatus, and distance calculation method that include confidence calculation of distance information","description":"A distance calculation apparatus calculates distance information based on a first image, which is generated based on luminous flux that passed through a first pupil region, and a second image, which i","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10477100","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.
