In one aspect, a digital image is received and brightness of the digital image is determined. The brightness of the digital image can include luminance or color. Maximum available detail in the digital image is brought out at least in part by applying to the brightness of the digital image a first gamma exponent that is equal to one divided by a negative of an average logarithm of the brightness of the digital image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gamma adjustment for maximizing information in images","description":"Methods, systems, and apparatus, including computer programs encoded on computer storage media, are described for transforming an image at least in part by using a gamma transformation that maximizes ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8538145","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.
