When the manual trapezoidal distortion correction is conducted after the automatic trapezoidal distortion correction, the trapezoidal distortion correction unit determines whether an angle deviation of the inclination angle exceeds for a given threshold angle for a given time period. When the trapezoidal distortion correction unit determines that the angle deviation exceeds the given threshold angle, the automatic trapezoidal distortion correction is conducted again."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Projector, trapezoidal distortion correction method, and storage medium storing trapezoidal distortion correction program","description":"A projector includes a projection unit to project an image on a screen; an angle detector to detect shaking of the projection unit; and a trapezoidal distortion correction unit to conduct automatic tr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9607363","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.
