摘要： This application discloses a voltage adjustment method and an electronic device. The method includes: obtaining a target luminance value of current display of a display pixel; determining a voltage increment value based on the target luminance value; and adjusting, based on the voltage increment value, an initial cathode voltage of an OLED device corresponding to the display pixel, where after voltage adjustment, a change amount between a luminance value of the display pixel and the target luminance value falls within a preset range. This application may be applied to an electronic device, and display quality of a display screen may be improved while power consumption of the display screen is reduced.

摘要： This application discloses a photographing method and apparatus, to overcome blurring that occurs during photographing. When a zoom ratio is greater than a first zoom ratio threshold, a long-focus camera is started to capture an image. A zoom ratio of the long-focus camera is greater than or equal to the first zoom ratio threshold. Because a high zoom ratio causes large shake, a rotational blur occurs in the image. According to the photographing method disclosed in this application, a first neural network model for rotational image deblurring is used to implement rotational image deblurring processing. In this way, high imaging quality of an image, a video, or a preview image is presented to a user to some extent, and an imaging effect may not be inferior to an effect of photographing with a tripod.

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.
