Abstract: A method includes obtaining a first preview picture collected by a camera, where an angle of view FOV of the camera is a first FOV value. The camera collects the first preview picture based on a second FOV value, and the second FOV value is less than the first FOV value. The method further includes adjusting the second FOV value to a third FOV value when it is detected that a quantity of at least one target human face in the first preview picture is greater than a first preset value, where the third FOV value is greater than the second FOV value, and the third FOV value is less than or equal to the first FOV value; and outputting an image that is photographed by the camera based on the third FOV value.

Abstract: A photographing method includes an electronic device that recognizes a gesture of a user using a front-facing camera, and sequentially displays a series of images in a preview box when recognizing a specific gesture. Preview angles presented by the series of images are gradually changed. For example, when the front-facing camera recognizes a gesture of opening a palm and pushing forward, the preview angles presented by the series of images sequentially displayed by the electronic device in the preview box are gradually increased, to present more scenes in the preview box.

Abstract: A photographing method and a device configured to capture, in a slow shutter exposure mode, a photo in which a subject image is clear and a background image has a motion blur, so as to improve a photographing experience. The device may display a preview image with an image of a first object in a preview background image a motion blur, and a preview subject image not having a motion blur. The device may display an intermediate image on a photographing interface after detecting a photographing operation. On the intermediate image, an image of a second object in an intermediate background image has a motion blur, and an intermediate subject image does not have a motion blur. On a generated photo, an image of the second object in a target background image has a motion blur, and a target subject image does not have a motion blur.

Abstract: This application discloses an image content removal method, and relates to the field of computer vision. The method includes: enabling a camera application; displaying a photographing preview interface of the camera application; obtaining a first preview picture and a first reference frame picture that are captured by a camera; determining a first object in the first preview picture as a to-be-removed object; and determining to-be-filled content in the first preview picture based on the first reference frame picture, where the to-be-filled content is image content that is of a second object and that is shielded by the first object in the first preview picture. The terminal generates a first restored picture based on the to-be-filled content and the first preview picture. In this way, image content that a user does not want in a picture or a video shot by the user can be removed.
