An image recognition program includes a license plate recognition section that detects a license plate of the preceding vehicle from the image, and a cut-off line recognition section that detects a cut-off line of the headlight from the image. The control value calculation section calculates the control value for the light distribution pattern such that the cut-off line detected by the cut-off line recognition section is positioned higher by a predetermined height than an upper end of the license plate detected by the license plate recognition section."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Headlight control device, headlight control system, and headlight control method","description":"A headlight control device which recognizes an oncoming vehicle using a camera without dazzling the driver of the oncoming vehicle includes a sequence control section that generates a headlight contro","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11938858","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.
