Abstract: An image capture method, an image display method, and an apparatus are provided to reduce a difference between an image displayed on a display end and an image displayed on a capture end. During encoding, the capture end transmits data for describing a luminance mapping relationship between a before-compression image and an after-compression image to the display end, so that consistency between the image on the capture end and the image on the display end is ensured as much as possible. In addition, screen related information for describing luminance of the capture end is transmitted to the display end, so that the display end adjusts backlight and a pixel value based on the screen related information, to improve consistency between the image on the capture end and the image on the display end.

Abstract: Embodiments of this application provide an image processing method and an electronic device, and relate to the field of image processing technologies. The method includes: obtaining display information of a to-be-displayed image at current target backlight luminance of a display and display information of the to-be-displayed image at luminance that is of the display and that is higher than the current target backlight luminance, and obtaining display information of the to-be-displayed image based on the two types of display information.

Abstract: 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.
