Abstract: Obtaining a first set including key point descriptors in a first image that is of a to-be-shot scene and that is formed by using a first camera in a dual camera system, and a second set including key point descriptors in a second image that is of the to-be-shot scene and that is formed by using a second; pairing a key point in the first set and a key point in the second set that match each other to form a key point pair; selecting the key point pair that meets a predetermined condition; generating an image alignment vector field according to the selected key point pair; and estimating an occlusion area according to the depth information of the first image and the second image, and eliminating an alignment vector of the occlusion area in the image alignment vector field, to form a corrected image alignment vector field.

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 includes: starting a camera in response to a first operation; entering a first video recording mode in response to a second operation; capturing first video frames in response to a third operation; and stopping capturing the first video frames in response to a fourth operation, to obtain a target video. The ith second video frame in the target video is obtained by fusing a foreground image of the kth first video frame captured by the camera and a background image of the jth first video frame captured by the camera, and the (i+1)th second video frame in the target video is obtained by fusing a foreground image of the (k+m)th first video frame captured by the camera and a background image of the (j+n)th first video frame captured by the camera, where m≠n. In this way, the electronic device can record a video with a special effect.

Abstract: A method and a terminal are provided by various embodiments of the present invention in which: M cameras are configured to continuously shoot a same scene for K times, where M≧2, K≧2, and each of the M cameras simultaneously collects one frame of image at each time of shooting; and a processor, connected to the M cameras and configured to perform registration on images obtained at the K times of shooting, and perform temporal and spatial filtering on the registered images. In the embodiments of the present invention. Because the multiple cameras simultaneously collect an image at each time of shooting, a time interval at which a particular quantity of images are collected by the terminal is shorter than that at which the particular quantity of images are collected by a single camera, and a probability of an occurrence of hand trembling or object motion within the time interval also correspondingly decreases.

Abstract translation: 本发明的各种实施例提供了一种方法和终端，其中：M个摄像机被配置为连续拍摄相同场景K次，其中M≥2，K≥2，并且M个摄像机中的每一个同时收集一帧 每次拍摄时的图像; 以及处理器，连接到M个摄像机并被配置为对在拍摄的K次获得的图像进行登记，并对登记的图像执行时间和空间过滤。 在本发明的实施例中。 由于多个照相机在每次拍摄时都同时收集图像，所以终端收集特定数量的图像的时间间隔比单个照相机收集特定数量的图像的时间间隔短，并且概率 在时间间隔内手抖或物体运动的发生也相应地减小。
