Method for capturing image in video recording and electronic device

An electronic device, comprising:

• a touchscreen, a memory, a camera, a display, a temperature sensor, and a processors, wherein the touchscreen, the memory, the camera, and the display are coupled to the processor, 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 a method, the method comprising:
• receiving a first operation of a user, wherein the first operation is used to trigger the electronic device to start to record a video;
• collecting, with the camera, a first image in response to the first operation, and displaying a first interface, wherein the first interface is a viewfinder interface in which the electronic device is recording the video, a preview stream is displayed in the viewfinder interface, the preview stream comprises a preview image obtained based on the first image, the first interface further comprises a snapshot shutter, and the snapshot shutter is configured to trigger the electronic device to capture an image to obtain a photo;
• 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;
• selecting, based on additional information of the first image in response to a second operation performed by the user on the snapshot shutter, a second image from the n frames of first images buffered in the first buffer queue, wherein the additional information of the first image comprises at least one of contrast of the first image, an angular velocity at which the camera collects the first image, or a timestamp of the first image;
• and
• performing first image processing on m frames of first images comprising the second image, to obtain a captured image, wherein the first image processing comprises cropping processing performed based on a cropping manner and a cropping parameter of a target preview image, the target preview image is a frame of image that is in the preview stream and that is collected by the camera when the electronic device receives the second operation, m≥1, and m is an integer, wherein the cropping parameter of the target preview image comprises center point coordinates of a cropping area of the target preview image and cropping size information and wherein the first image processing further comprises:
• collecting current temperature of the electronic device,
• in response to the current temperature of the electronic device being greater than a preset temperature threshold, performing the first image processing on only the second image to obtain a third image,
• in response to the current temperature of the electronic device being less than or equal to the preset temperature threshold, performing image fusion on a plurality of the m frames of first images to obtain the third image, and
• determining the captured image based on the third image.

A non-transitory computer-readable storage medium, comprising computer instructions, wherein when the computer instructions are run on an electronic device, the electronic device is enabled to:

• receive a first operation of a user, wherein the first operation is used to trigger the electronic device to start to record a video;
• collect, with a camera, a first image in response to the first operation, and displaying a first interface, wherein the first interface is a viewfinder interface in which the electronic device is recording the video, a preview stream is displayed in the viewfinder interface, the preview stream comprises a preview image obtained based on the first image, the first interface further comprises a snapshot shutter, and the snapshot shutter is configured to trigger the electronic device to capture an image to obtain a photo;
• buffer, 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;
• select, based on additional information of the first image in response to a second operation performed by the user on the snapshot shutter, a second image from the n frames of first images buffered in the first buffer queue, wherein the additional information of the first image comprises at least one of a contrast of the first image, an angular velocity at which the camera collects the first image, or a timestamp of the first image;
• and
• perform first image processing on m frames of first images comprising the second image, to obtain a captured image, wherein the first image processing comprises cropping processing performed based on a cropping manner and a cropping parameter of a target preview image, the target preview image is a frame of image that is in the preview stream and that is collected by the camera when the electronic device receives the second operation, m≥1, and m is an integer, wherein the cropping parameter of the target preview image comprises center point coordinates of a cropping area of the target preview image and cropping size information and wherein the first image processing further comprises to:
• collect current temperature of the electronic device,
• in response to the current temperature of the electronic device being greater than a preset temperature threshold, perform the first image processing on only the second image to obtain a third image,
• in response to the current temperature of the electronic device being less than or equal to the preset temperature threshold, perform image fusion on a plurality of the m frames of the first images to obtain the third image, and
• determine the captured image based on the third image.
