Abstract: This application discloses a video image anti-shake method and a terminal, and relates to the field of image processing, to implement compensation for translational shake in a Z direction. A video image anti-shake method includes: turning on, by a terminal, a camera lens, and photographing a video image by using the camera lens; detecting, by the terminal, shake on an X-axis, a Y-axis, and a Z-axis during photographing, where the Z-axis is an optical axis of the camera lens, the X-axis is an axis perpendicular to the Z-axis on a horizontal plane, and the Y-axis is an axis perpendicular to the Z-axis on a vertical plane; and performing, by the terminal, anti-shake processing on the video image based on the shake on the X-axis, the Y-axis, and the Z-axis. Embodiments of this application are applied to video image anti-shake.

Abstract: Embodiments of this application provide an image obtaining method and a terminal device. When the terminal device moves, a motion sensor collects motion data of the terminal device, and sends the motion data to an optical image stabilization OIS controller and an electronic image stabilization EIS controller, where the terminal device includes the motion sensor, the OIS controller, the EIS controller, and an image sensor. The OIS controller controls, based on the motion data, a lens of the terminal device to move. The image sensor collects an image sequence. The EIS controller performs, by using movement information of the lens and the motion data, jitter compensation on the image sequence collected by the image sensor, so that stability of an obtained image can be improved.

Abstract: This application provides a photographing method and an electronic device, and relates to the field of terminal technologies, to ensure stabilization performance existing during photographing in a zoom scenario, and improve definition of a photographing image. The method includes: obtaining a first photographing image through a first camera; determining a first crop ratio of the first photographing image based on a first zoom ratio of the first photographing image; cropping the first photographing image based on the first crop ratio; obtaining a second photographing image through the first camera in response to a first zoom operation; and cropping the second photographing image based on the second crop ratio; wherein the second crop ratio is greater than the first crop ratio, and a stabilization angle of the second photographing image is a product of the FOV of the first camera and the second crop ratio.
