The imaging apparatus also includes a point light source determination unit that acquires the maximum value of contrast for each horizontal line in the video as a line evaluation value and determines whether the captured video is a night scene based on whether or not the line evaluation value has a characteristic of an object as a point light source. If the histogram shape determination unit and the point light source determination unit determine that the captured video is a night scene, the imaging apparatus determines that the scene captured by the image capturing unit is a night scene."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Video processing apparatus and video processing method","description":"An imaging apparatus includes a histogram shape determination unit that acquires a histogram of luminance values from video captured by an image capturing unit and determines whether or not the captur","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8502913","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.
