A main control section determines, as a dimming target segment, a segment having a number of high luminance pixels equal to or greater than a first number of pixels. A low luminance pixel specifying section specifies low luminance pixels among the pixels corresponding to the dimming target segment. A gain correction section performs gain correction on pixel signal values of the low luminance pixels, with a gain value corresponding to a ratio of the high transmittance to the low transmittance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Imaging device including light modulation element that varies between high and low transmittance for each segment","description":"Provided is an imaging device capable of expanding the dynamic range and eliminating differences in level occurring in low luminance regions between segments having different transmittances.A number o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9769391","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.
