The image projection apparatus (1) includes a MEMS mirror device (11), a MEMS mirror control unit (13), and a laser beam detector (19). The MEMS mirror control unit (13) makes the laser beam detector (19) irradiated with a first light beam (L1), and at this time adjusts a position of a first display image (18a) on the basis of a difference between a detection signal output from a first light sensor (191) and a detection signal output from a second light sensor (192); the MEMS mirror control unit (13) makes a first light reception surface and a second light reception surface irradiated with a second light beam (L2), and at this time adjusts a position of a second display image (18b) on the basis of a difference between a detection signal output from the first light sensor (191) and a detection signal output from the second light sensor (192)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image projection apparatus","description":"An image projection apparatus (1) joins a plurality of display images displayed by scanning a plurality of light beams, as if there is no seam between them, thereby displaying a large-sized high-quali","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9800844","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.
