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.

Abstract: A photographing method in a telephoto scenario and a mobile terminal are disclosed, which are related to the field of communications technologies, so as to improve sharpness of a photographed object in an image, blur a background, highlight the photographed object, and improve an overall visual effect of the image. The method specifically includes: in a telephoto photographing scenario, when a mobile terminal display a preview or photographed image, recognizing a target photographed object and a background of the target photographed object based on the image collected by a camera; and improving image sharpness of an area in which the target photographed object is located, and adding a blurring effect to the image of the area in which the background of the target photographed object is located.

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.

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: A method for calculating a dual-camera relative position provided in the present disclosure includes obtaining M groups of dual-camera images, where each group of dual-camera images in the M groups includes two images obtained by photographing a same scene by dual cameras at the same time, screening the M groups of dual-camera images to obtain Q groups of dual-camera images that can be used to calculate the dual-camera relative position, obtaining dual-camera relative position parameters corresponding to each group of dual-camera images in the Q groups according to each group of dual-camera images in the Q groups, and obtaining optimal dual-camera relative position parameters from the Q groups of dual-camera relative position parameters. Therefore, the dual-camera relative position can be calculated when a scene is relatively difficult to recognize.
