A viewfinder (30), which superimposes a display of a finder LCD (36) on an optical image of a subject observed through an observation optical system (32), includes a variable ND filter (40) that adjusts the light amount of the optical image of the subject. While power of the digital camera is turned off, information about the time is acquired, and the target transmittance of the variable ND filter (40) is updated on the basis of the information about the transmittance determined for each time zone. In a case where the target transmittance is updated, the variable ND filter (40) is driven to change the transmittance of the variable ND filter (40) to the target transmittance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Imaging apparatus, finder display control method of imaging apparatus, and finder display control program of imaging apparatus","description":"Provided are an imaging apparatus capable of ensuring favorable visibility of display in a finder from when power is applied, a finder display control method of the imaging apparatus, and a finder dis","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11233947","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.
