The illumination controller is configured to set a phase for an emission timing of the illumination light in an exposure period during which the imager stores the electric charge to be an identical phase at the frequency in each frame, and refer to respective phases set in exposure periods of chronologically adjacent frames to set an emission timing of the illumination light in the readout period."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Imaging system, processing device and illumination control method to set emission timing of illumination light in readout period of signal value of imager","description":"An imaging system includes: a light source configured to emit illumination light; an imager configured to store an electric charge corresponding to an amount of received light and read out the stored ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11503990","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.
