The deflection angle controller corrects a deflection angle in the vertical scanning direction of the optical scan device, based on a number of times the laser beam is detected by the first light receiving region and a number of times the laser beam is detected by the second light receiving region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image projection apparatus and image projection method","description":"An image projection apparatus includes a light irradiation device configured to irradiate a laser beam, an optical scan device configured to deflect the laser beam to make an optical scan, and project","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11243459","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.
