摘要： Embodiments of this application provide a time-lapse shooting method and a device, and relate to the field of shooting technologies. Therefore, a shooting scenario may be automatically identified, a plurality of photos with a relatively good effect are obtained through shooting based on a target shooting parameter that matches the shooting scenario, and video coding is performed on the plurality of photos to generate a time-lapse video with a relatively good effect. A specific solution is: After detecting a first operation, an electronic device starts a camera; after detecting a second operation, enters a time-lapse mode, and displays a preview interface, where the preview interface includes a first preview image; identifies a shooting scenario based on the first preview image; determines a target shooting parameter based on the shooting scenario; after detecting a third operation that a user indicates to start shooting, obtains a plurality of target photos through shooting based on the target shooting parameter; displays a shooting interface; and after detecting a fourth operation that the user indicates to stop shooting, generates a time-lapse video based on the plurality of target photos. The embodiments of this application are used for time-lapse shooting.

摘要： A photographing method and an electronic device that relate to the field of terminal technologies are provided. An electronic device is enabled to record a video with a special effect. This makes video recording more interesting and improves user experience. The method is applied to an electronic device having a display and a camera. The method specifically includes: starting the camera in response to a first operation; entering a first video recording mode in response to a second operation; capturing first video frames in response to a third operation; and stopping capturing the first video frames in response to a fourth operation, to obtain a target video. The i th second video frame in the target video is obtained by fusing a foreground image of the k th first video frame captured by the camera and a background image of the j th first video frame captured by the camera, and the (i+1) th second video frame in the target video is obtained by fusing a foreground image of the (k+m) th first video frame captured by the camera and a background image of the (j+n) th first video frame captured by the camera, where m≠n. In this way, the electronic device can record a video with a special effect.

摘要： Embodiments of this application provide a photographing method and a device, and relate to the field of electronic technologies, 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 photographing experience of a user. A specific solution is as follows: An electronic device enters a target photographing mode, and displays a first preview image on a preview interface. On the first preview image, an image of a first object in a preview background image has a motion blur, and a preview subject image does not have a motion blur. The electronic device displays 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. The electronic device stops photographing and generates a photo. On the 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. Embodiments of this application are used for slow shutter photographing.

摘要： This application provides a picture processing method and an apparatus. At an encoder side, the method includes: The encoder side obtains a to-be-processed picture, obtains a plurality of groups of visual sensory experience parameters, and encodes the to-be-processed picture and the plurality of groups of visual sensory experience parameters. At a decoder side, the method includes: The decoder side obtains a to-be-processed picture, obtains a zoom-in operation instruction, obtains one or more groups of visual sensory experience parameters corresponding to one or more local pictures, and separately processes the corresponding local picture based on the one or more groups of visual sensory experience parameters to obtain a processed local picture. In this application, a picture presented by a zoomed-in region can be used to simulate visual sensory experience for a real scene that is of a to-be-zoomed-in region and that is perceived by human eyes. This resolves a problem that a zoomed-in picture is unclear and blurred, and can improve visual zoom-in experience of a user.

摘要： This application provides an image distortion correction method and an apparatus. The method includes: performing optical distortion correction on a collected source image, to obtain a first corrected image, where the first corrected image includes a background region and a portrait in which stretching deformation occurs, and the portrait in which stretching deformation occurs includes at least a first human body region in which stretching deformation occurs and a second human body region in which stretching deformation occurs; and performing algorithm constraint correction on the first human body region, the second human body region, and the background region, to obtain a second corrected image, where constraint terms used for the algorithm constraint correction respectively constrain the first human body region, the second human body region, and the background region. In this way, the stretching deformation in both the first human body region and the second human body region is corrected, and for human vision there is no discontinuity in image content throughout the portrait in the background region. In this application, natural image distortion correction can be implemented, and therefore user experience is improved.
