The microlens array has multiple types of microlenses, for different polarization states, that focus light incident thereon to form individual images on an image-acquisition surface of the image-acquisition device and that are arranged in an array in directions orthogonal to an optical axis thereof, and the distance calculating portion calculates the distance by performing matching processing in which each polarization state is weighted according to frequency components of the information obtained by the image-acquisition device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image-acquisition apparatus for performing distance measurement using parallax","description":"Provided is an image-acquisition apparatus including an image-acquisition lens that collects light coming from a subject A; an image-acquisition device that acquires images with the light collected by","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9756304","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.
