In one embodiment, the captured image's histogram may be analyzed to determine if the image is indicative of the presence of exposure blowouts. Once it has been determined that there likely are blowouts in the image, an exposure bias for the image capture device may be set accordingly. Particularly, the exposure value (EV) for the image capture device may be gradually corrected, e.g., by one-eighth of a stop per captured frame, until the image histogram is no longer indicative of blown out regions, at which point the image capture device's exposure value may gradually be corrected back to “normal,” i.e., non-exposure bias compensated, levels."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Auto exposure blowout prevention","description":"Systems, methods, and a computer readable medium for performing an improved blowout prevention process in an image capture device are provided to compensate for occurrences of exposure “blowouts,” i.e","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8493500","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.
