A measurement template block is, provided for at least four adjacent sensor elements of the image sensor array. The method/apparatus can be used in any kind of digital camera and allows for a fast generation of image data with a hardware implementation of low complexity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and an apparatus for difference measurement of an image","description":"In a method and apparatus for difference measurement of an image, the image is detected by an image sensor array having (N×N) sensor elements, wherein N=2n, n≧2, and n being an integer number, each de","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8463048","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.
