Abstract: 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 the imaging effect may not be inferior to the effect of photographing with a tripod.

Abstract: The technology of this application relates to 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 can be improved while reducing power consumption of the display screen.
