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.

Abstract: A content push method is provided. The method is applied to a terminal, which includes a first set of cameras. The method includes: when the terminal is in a screen-locked state and an off-screen is woken up, capturing a first set of face images of a user by using the first set of cameras; determining whether the first set of face images matches a registered user; if the first set of face images matches the registered user, performing, by the terminal, an unlocking operation, and determining a facial attribute of the user based on the first set of face images; determining a to-be-pushed media resource based on the facial attribute; and pushing the media resource in an interface displayed after the terminal is unlocked.

Abstract: A method and an apparatus for obtaining an extended depth of field image, and an electronic device are disclosed. The method includes: determining a target focal length range based on an initial focal length (101), 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 (102); and registering and fusing, the plurality of images to obtain an extended depth of field image (103). The target focal length range of concern to a user is selected based on the initial focal length, so 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.
