Image obtaining method and electronic device

An electronic device, comprising:

• a touchscreen, a memory, a camera, a display screen, and one or more processors;
• wherein the touchscreen, the memory, the camera, and the display screen are coupled to the processor;
• and the memory stores computer program code, the computer program code comprises computer instructions, and when the computer instructions are executed by the processor, the electronic device is enabled to perform operations comprising:
• receiving a first operation of a user, wherein the first operation triggers starting video recording;
• displaying a first interface in response to the first operation, wherein the first interface is a viewfinder interface on which the electronic device is recording a video, the first interface comprises a preview image, and the preview image is obtained from a first image collected by a camera of the electronic device after the electronic device receives the first operation;
• selecting a second image from a first video stream, wherein the second image comprises an image of a target object, and the first video stream is obtained by an image signal processor (ISP) of the electronic device by performing first processing on a plurality of frames of first images, and the first processing comprises subsampling;
• buffering, in a first buffer queue, the first image collected by the camera, wherein n frames of first images collected by the camera are buffered in the first buffer queue, n≥1, and n is an integer;
• using, as an input, m frames of first images corresponding to the second image in the n frames of first images, and running a preset original RAW domain image processing algorithm to obtain a third image;
• wherein the preset RAW domain image processing algorithm has a function of improving image quality;
• and m≥1, and m is an integer;
• performing second processing on the third image by using the ISP, to obtain a fourth image;
• wherein the second processing does not comprise the subsampling;
• and
• displaying, after video recording ends, a highlight image obtained by encoding the fourth image.

A non-transitory computer-readable storage medium, comprising computer instructions which, when run on an electronic device, cause the electronic device to perform operations comprising:

• receiving a first operation of a user, wherein the first operation triggers starting video recording;
• displaying a first interface in response to the first operation, wherein the first interface is a viewfinder interface on which the electronic device is recording a video, the first interface comprises a preview image, and the preview image is obtained from a first image collected by a camera of the electronic device after the electronic device receives the first operation;
• selecting a second image from a first video stream, wherein the second image comprises an image of a target object, and the first video stream is obtained by an image signal processor (ISP) of the electronic device by performing first processing on a plurality of frames of first images, and the first processing comprises subsampling;
• buffering, in a first buffer queue, the first image collected by the camera, wherein n frames of first images collected by the camera are buffered in the first buffer queue, n≥1, and n is an integer;
• using, as an input, m frames of first images corresponding to the second image in the n frames of first images, and running a preset original RAW domain image processing algorithm to obtain a third image, wherein the preset RAW domain image processing algorithm has a function of improving image quality;
• and m≥1, and m is an integer;
• performing second processing on the third image by using the ISP, to obtain a fourth image;
• wherein the second processing does not comprise the subsampling;
• and
• displaying, after video recording ends, a highlight image obtained by encoding the fourth image.
