Abstract: Embodiments of this application provide a photographing method and an electronic device. In the method, the electronic device displays an image preview interface of a target application, where the target application is an application with a camera function, and a preview image frame displayed in the image preview interface is collected based on an image preview request continuously delivered by the target application; the target application generates an image shooting request in response to a received user operation, where an exposure parameter of the image shooting request is different from an exposure parameter of the image preview request; and if both the unprocessed image preview request and the unprocessed image shooting request exist, the electronic device invokes an image sensor to collect a shot image frame corresponding to the image shooting request.

Abstract: A shooting method and a related device. According to the shooting method, a camera application in an electronic device may send an instruction of shooting in advance through a custom interface when a user taps a shutter control. The electronic device may determine a current 3 A state based on the instruction of shooting. If the current 3 A state is a 3 A lock state, the electronic device obtains an image frame. In the foregoing process, the electronic device may further capture a variable exposure frame in advance, and obtain an image in a buffered frame queue based on address information and a reference count of the image. The electronic device may not only increase a shooting response speed of the electronic device, but also select a clearer image for fusion more accurately. This increases definition of a shot image and improves shooting experience of the user.

Abstract: An automatic photographing method and an electronic device. The method includes: collect an image frame sequence from image data obtained by a camera sensor, and detect a semantic meaning and picture quality of each image frame in the image frame sequence; buffer the image frame if it is detected that the semantic meaning and the picture quality of the image frame meet a preset buffer condition; and if it is detected that the semantic meaning and the picture quality of the image frame meet a preset photographing triggering condition, invoke a preset photographing algorithm to process to-be-photographed data to generate a photographing result. An entire process does not need to be actively triggered by a user. The hardware abstraction layer may detect each frame of image in real time after a camera application is started, and automatically buffers the image or triggers photographing when the image meets a preset condition.

Abstract: Embodiments of this application provide a photographing method and related apparatus, which are applied to terminal technologies. The method includes: when the terminal device displays the photo previewing interface, frames are previewed in a cache queue; receiving and responding to the photo-taking operation in the previewing interface, The image from the cache queue is managed in undeletable state; After completing the algorithm processing based on the selected image, the selected image is deleted; The terminal device generates a photo based on the processed image. In this way, the selected image in the cache queue is managed undeletably, so that the selected image is not cleared when the terminal device generates the picture. Then, the cache queue may reserve the selected image for a long time, and the terminal device does not need to copy and store the selected image. Therefore, large memory occupation caused by copy is reduced, and save power.
