The imaging and processing circuit generates, in a certain sensing element associated with said certain pixel and in two or more of its closest neighboring sensing elements, sensed signal levels, respectively, based on sensed light during an exposure to light. It provides, based on comparisons between said sensed signal levels and at least two different threshold levels, binarized image data of said certain sensing element and said two or more of its closest neighboring sensing elements. The imaging and processing circuit then identifies, by means of a computing element configured to operate on the provided binarized image data, said certain pixel as the local extreme point based on that the provided binarized image data of said certain sensing element differ from the provided binarized image data of said two or more of its closest neighboring sensing elements."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and arrangements for identifying a pixel as a local extreme point","description":"Method and an imaging and processing circuit for identifying a certain pixel as a local extreme point.
