Photographing method and electronic device

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.

SELECTIVELY INCREASING DEPTH-OF-FIELD IN SCENES WITH MULTIPLE REGIONS OF INTEREST
20230012219 · 2023-01-12 ·

The present disclosure provides systems, apparatus, methods, and computer-readable media that support multi-frame depth-of-field (MF-DOF) for deblurring background regions of interest (ROIs), such as background faces, that may be blurred due to a large aperture size or other characteristics of the camera used to capture the image frame. The processing may include the use of two image frames obtained at two different focus points corresponding to the multiple ROIs in the image frame. The corrected image frame may be determined by deblurring one or more ROIs of the first image frame using an AI-based model and/or local gradient information. The MF-DOF may allow selectively increasing a depth-of-field (DOF) of an image to provide focused capture of multiple regions of interest, without causing a reduction in aperture (and subsequently an amount of light available for photography) or background blur that may be desired for photography.

Method for the noise optimization of a camera, in particular a handheld thermal imaging camera

The disclosure relates to a method for the noise optimization of a camera, in particular a handheld thermal imaging camera. Images are captured by means of the camera in at least one method step; at least one movement characteristic variable is detected by means of at least one sensor unit of the camera in at least one method step; and image data of captured images is averaged by means of a computing unit of the camera in at least one method step. At least a number of images to be averaged are determined by means of the computing unit of the camera at least on the basis of an intensity of the detected movement characteristic variable, in particular a change rate, in at least one method step.

Methods and apparatus for using a controllable physical light filter as part of an image capture system and for processing captured images

Methods and apparatus for using a controllable filter, e.g., an liquid crystal panel, in front of a camera are described. The filter is controlled based on the luminosity of object in a scene being captured by the camera to reduce or eliminate luminosity related image defects such as flaring, blooming or ghosting. Multiple cameras and filters can be used to capture multiple images as part of a depth determination processes where pixel values captured by cameras at different locations are matched to determine the depth, e.g., distance from the camera or camera system to object in the environment. Pixel values are normalized in some embodiments based on the amount of filtering applied to a sensor region and sensor exposure time. The filtering allows for regional sensor exposure control at an individual camera even though the overall exposure time of the pixel sensors may be and often will be the same.

Method for stabilizing a camera frame of a video sequence
11531211 · 2022-12-20 · ·

A method for stabilizing a video sequence comprises: obtaining an indication of camera movement from acquisition of a previous camera frame to acquisition of a current camera frame; determining an orientation for the camera at a time of acquiring the current camera frame; and determining a candidate orientation for a crop frame for the current camera frame by adjusting an orientation of a crop frame associated with the previous camera frame according to the determined orientation. A boundary of one of the camera frame or crop frame is traversed to determine if a specific point on the boundary of the crop frame exceeds a boundary of the camera frame. If so, a rotation of the specific point location which would bring the specific point location onto the boundary of the crop frame is determined and the candidate crop frame orientation updated accordingly before the crop frame is displayed.

The present disclosure provides systems and methods that use and/or generate image files according to a novel microvideo image format. For example, a microvideo can be a file that contains both a still image and a brief video. The microvideo can include multiple tracks, such as, for example, a separate video track, audio track, and/or one or more metadata tracks. As one example track, the microvideo can include a motion data track that stores motion data that can be used (e.g., at file runtime) to stabilize the video frames. A microvideo generation system included in an image capture device can determine a trimming of the video on-the-fly as the image capture device captures the microvideo.
