IMAGE AUTO-FOCUSING METHOD AND CAMERA USING SAME

摘要

The present disclosure provides a method for calculating a focusing evaluation value. 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.

1. A method for calculating a focusing evaluation value under a scene having a dynamic light source, comprising:
dividing an image region into a plurality of sub-regions; selecting a first sub-region from the plurality of sub-regions, wherein, the first sub-region is a sub-region affected by a dynamic light source; 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.
