  • Method and apparatus for obtaining extended depth of field image and electronic device
    Patent number: 12205313
    Abstract: A method and an apparatus for obtaining an extended depth of field image, where the method includes: determining a target focal length range based on an initial focal length, where the target focal length range includes the initial focal length; obtaining a plurality of images of a photographed object for a plurality of focal lengths in the target focal length range; and registering and fusing the plurality of images to obtain an extended depth of field image. The target focal length range of concern to a user is selected based on the initial focal length, such that there is no need to obtain images of all focal lengths of a lens, a quantity of obtained images and processing time of registration and fusion can be reduced.
