Problems solved by technology
[0004] At present, in electronic devices such as mobile phones, the maximum frame rate supported by image sensors is usually low, such as 30fps, 60fps, 120fps or 240fps, etc., and the video frame rate of electronic devices is also 30fps, 60fps, 120fps or 240fps, which usually cannot meet People want to distinguish the needs of high-speed motion process
For example, see figure 1 As shown in the playback effect diagram, when the video of the falling process of water droplets is recorded at a video frame rate of 240fps, and the video is played at a playback frame rate of 30fps, it is still difficult for users to see the rebound process of the water droplets falling on the water surface or the splashing when falling on the water surface The movement details of the small water droplets

Embodiment Construction
[0059] For ease of understanding, some descriptions of concepts related to the embodiments of the present application are given by way of example for reference. As follows:
[0060] Original frame rate: During video recording, the maximum number of video frames that can be collected per unit time supported by the hardware of the image sensor.
[0061] Video frame rate: The number of video frames recorded by electronic equipment per unit time. In the embodiment of the present application, when there is frame insertion, the video frame rate is greater than the original frame rate, the total number of video frames per unit time after the frame insertion.
[0062] Playback frame rate: when playing video, the number of video frames played by the electronic device per second.
[0063] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Among them, in the descrip...

Embodiments of the present application provide a slow-motion video recording method and electronic equipment, which relate to the field of camera technology, and can make the recording frame rate higher than the maximum frame rate supported by image sensor hardware, thereby improving user experience in recording slow-motion video. The specific solution is: the electronic device increases the recording frame rate of the recorded slow-motion video by interpolating frames. The embodiment of this application is used for video recording.
Description
technical field [0001] The present application relates to the field of electronic technology, in particular to a video recording method and electronic equipment. Background technique [0002] During video playback, if the number of frames per second played by electronic devices such as mobile phones is less than the number of frames recorded per second during video recording, there will be a slow-motion playback effect. For example, if the video is played at a playback frame rate of 30 frames per second (fps), then if the electronic device records the video at a recording frame rate of 60 fps, there will be a double slow-motion playback effect; 120fps video frame rate recording video, there will be 4 times the slow motion playback effect. [0003] Human eyes have limited ability to distinguish high-speed moving objects, and slow-motion video helps people see clearly the details of high-speed motion. The higher the video frame rate when recording a video, the better the slo...
