Description

Image generation method and electronic equipment Technical Field The present application relates to the field of terminal technologies, and in particular, to an image generating method and an electronic device. Background A user typically captures, via an electronic device, some motion scenes, which refers to scenes in which a subject is in motion, e.g., motion scenes may include moving objects (e.g., running people, running vehicles), changing environments (e.g., blowing leaves), sporting events (e.g., football matches), etc. If the electronic device shoots a moving scene by adopting exposure time aiming at a static scene, the shot image has the effect of motion blur, and the quality of the image generated by the electronic device is poor. If the effect of motion blur is required to be avoided, the electronic device may reduce the exposure time in the motion scene, however, the reduction of the exposure time may result in a degradation of the signal-to-noise ratio of the captured image, and the quality of the image generated by the electronic device is poor. Therefore, when the electronic equipment shoots a moving scene, the generated image has poor quality, and the visual experience of a user is affected. Disclosure of Invention The embodiment of the application provides an image generation method and electronic equipment, which can generate higher-quality images when the electronic equipment shoots a motion scene, thereby improving the visual experience of a user. In a first aspect, an embodiment of the present application provides an image generating method, applied to an electronic device, where the image generating method is used for acquiring at least one image frame, where the image frame is used for capturing a same motion scene, the motion scene includes at least one motion subject, each image frame includes a subject area corresponding to the motion subject, and a non-subject area other than the motion subject, and generating a target image based on a target non-subject area in the non-subject area and a target subject area in the subject area, where in a same capturing period, an exposure time of the target non-subject area is greater than an exposure time of the target subject area, or in a same image frame, a resolution of the target non-subject area is greater than a resolution of the target subject area. According to the method provided by the application, the main body area corresponding to the moving main body and the non-main body areas except the moving main body are divided in the acquired image frames, the target main body area with higher image quality is selected from the main body areas, and the target non-main body area with higher image quality is selected from the non-main body areas for image fusion processing, so that a target image with higher quality can be generated, and the visual experience of a user is improved. In one implementation, acquiring at least one image frame includes displaying a first interface in a camera application and displaying a viewfinder window on the first interface, and capturing the motion scene in response to the viewfinder window to acquire the image frame.

Therefore, as the electronic equipment captures the motion scene when the user does not perform shooting operation, the shooting efficiency is improved, and the shooting experience is enhanced. In one implementation, acquiring at least one image frame includes displaying a first interface in a camera application, displaying a viewfinder window on the first interface, and displaying a first control on the first interface, wherein the viewfinder window is used for finding a motion scene, the first control is used for shooting the motion scene in the viewfinder window, and shooting the motion scene in response to a first operation of the first control to acquire the image frame. By adopting the implementation mode, the electronic equipment responds to the user operation to view, so that the image frame acquired by the electronic equipment meets the user requirement. In one implementation, the image frames comprise a first image frame and a second image frame, and acquiring at least one image frame comprises acquiring one first image frame based on a single-frame progressive-stabilized image processing mode and one second image frame in each shooting period under the condition that a moving scene is shot based on a first zooming mode, wherein the exposure time of the first image frame is longer than that of the second image frame, and the zooming magnification corresponding to the first zooming mode is smaller than or equal to a first threshold value. With the implementation manner, under the basic zoom magnification (for exam
