The method may be applied in a scene having a dynamic light source and include: dividing an image region of a camera into a plurality of sub-regions; selecting a first sub-region which is affected by a dynamic light source from the plurality of sub-regions; correcting a focusing evaluation value of the first sub-region with the focusing evaluation value of each of sub-regions adjacent to the first sub-region; and calculating a focusing evaluation value of the whole image region based on the focusing evaluation value of each of the sub-regions. The present disclosure improves the performance of auto-focusing in a scene having a dynamic light source."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image auto-focusing method and camera using same","description":"The present disclosure provides a method for calculating a focusing evaluation value.
