A brightness of the image in the second mode is lower than that in the first mode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image projection apparatus, image projection method, and computer-readable storage medium","description":"An image projection apparatus includes a light source configured to emit light with a luminance according to electric power; a color wheel configured to sequentially transmit the light through multipl","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9787957","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.
