摘要： This application discloses a recording frame rate control method, including the following steps: First, a mobile terminal receives first input of a user, and the mobile terminal starts video recording in response to the first input. Then, the mobile terminal collects N video frames of a photographing scenario at a first frame rate. Next, the mobile terminal determines light intensity in the photographing scenario based on the collected N video frames, and automatically adjusts a recording frame rate of the mobile terminal based on the light intensity in the photographing scenario, where a recording frame rate obtained after the adjustment is different from the first frame rate, and N is a positive integer greater than 2. Further, the mobile terminal continues collecting a video frame of the photographing scenario based on the recording frame rate obtained after the adjustment. Finally, the mobile terminal generates a video file based on the video frames that are collected at the first frame rate and the video frame that is collected based on the recording frame rate obtained after the adjustment. In this way, a frame rate used during video recording is automatically adjusted, and quality of a video image is improved.

摘要： 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, where a stabilization angle of the first photographing image is a product of an FOV of the first camera and the first crop ratio; 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; determining a second crop ratio of the second photographing image based on a second zoom ratio of the second photographing image, where the second zoom ratio is greater than the first zoom ratio, 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; and cropping the second photographing image based on the second crop ratio.

摘要： Embodiments of the present invention disclose a depth information obtaining method and apparatus, and an image acquisition device. The image acquisition device includes a first camera and a second camera. When detecting that shaking occurs, the depth information obtaining apparatus may obtain images captured by the first camera and the second camera, detect an initial distance between a target shooting object in the two images, correct the initial distance by using an offset difference between a first image and a second image, and determine a depth of the target shooting object by using the corrected initial distance. In the embodiments of the present invention, the two cameras may both have an OIS function, or either of the cameras has an OIS function. When performing OIS, the depth information obtaining apparatus corrects the distance between the same shooting object in the images obtained by the two cameras, so that finally obtained depth information is relatively accurate. This can accurately and quickly implement focusing on the shooting object.
