Problems solved by technology

[0002] Current electronic devices, such as DV (Digital Video, digital video camera), smartphones, tablet computers, etc., cannot realize the intelligent screen recording of video, and the display direction of the recorded screen during video playback will change with the posture of the electronic device during the recording process. change, cannot remain stable and consistent
[0003] That is to say, in the process of recording video, when the display direction of the screen of the current electronic device changes, it cannot perform linkage processing on the recorded video screen, so as to maintain the consistency of the display direction of the entire video content
For example, in the process of using a smartphone to record vertically, if the smartphone is rotated 90 degrees to the left and then recorded horizontally, when the video is played, the recorded video after rotating the screen will be in a direction that is 90 degrees away from the recorded screen before turning the screen. Playing and displaying, the display direction of the recorded video screen changes with the change of the posture of the electronic device during recording, which cannot maintain the consistency of the entire video display direction, resulting in poor user experience

Embodiment 1

[0058] refer to figure 1 , figure 1 It is a flow chart of Embodiment 1 of a video processing method provided by this application. The method is applied to electronic equipment, for example, it can be specifically applied to electronic equipment with video recording functions such as DV, smart phones, and tablet computers, such as figure 1 As shown, the method may include the following steps:

[0059] S101: After the video recording is started by the electronic device, the attitude parameter of the electronic device is acquired in real time through a sensor.

[0060] During the video recording process, when the posture of electronic devices such as DV, smartphones, and tablet computers changes, the display direction of the screen (you can choose to use a side line of the display screen as a reference) will also change accordingly. For example, when using a smartphone During the process of recording video on the vertical screen, rotate it 90 degrees to the left for horizontal ...

Embodiment 2

[0071] refer to figure 2 , figure 2 It is a flow chart of Embodiment 2 of a video processing method provided by this application. This embodiment specifically provides a solution for performing angle compensation processing on each recorded frame of image in real time during the video recording process. Such as figure 2 As shown, the step S103 can be realized through the following steps:

[0072] S201: During the video recording process, calculate the current angular displacement of the electronic device in real time according to the angular velocity and the linear acceleration, and the angular displacement is based on the position of the electronic device when recording is started;

[0073] S202: Based on the angular displacement, determine in real time the current first rotation direction and first rotation angle of the screen display direction of the electronic device;

[0074] S203: Determine in real time a first angle compensation strategy in which the compensation ...

Embodiment 3

[0088] refer to image 3 , image 3 It is a flow chart of the third embodiment of a video processing method provided by the present application. This embodiment specifically provides a solution for performing angle compensation processing on each frame of the recorded image after the video recording ends. Compared with the second embodiment, The time node for realizing the angle compensation processing in this embodiment has been changed. Such as image 3 As shown, the step S103 can be realized through the following steps:

[0089] S301: After the video recording ends, calculate the angular displacement of the electronic device at that time according to the angular velocity and the linear acceleration acquired during the recording process, and the angular displacement is based on the position of the electronic device when the recording is started;

[0090] S302: Based on the angular displacement, determine a second rotation direction and a second rotation angle of the scree...

Abstract

The invention discloses a video processing method and electronic equipment. The video processing method comprises the following steps of obtaining attitude parameters corresponding to the electronic equipment in a video recording process in real time through a sensor, making an angle compensation strategy for corresponding intake image frame data by utilizing the obtained attitude parameters, and subsequently carrying out corresponding angle compensation processing on the frame image according to the made angle compensation strategy so as to still keep a video recording picture stable and consistent in an attitude variation process of the electronic equipment when a video is played. Through the video processing method and the electronic equipment, the angle compensation is carried out in a display direction of the video recording picture based on the attitude parameters of the electronic equipment in the video recording process, so that the problem of intelligent screen rotation recording of the video is solved, the display direction of the recorded picture cannot change with the attitude of the electronic equipment during recording when the video is played, and the user experience is better.

Description

technical field [0001] The invention belongs to the technical field of video recording and processing, and in particular relates to a video processing method and electronic equipment. Background technique [0002] Current electronic devices, such as DV (Digital Video, digital video camera), smartphones, tablet computers, etc., cannot realize the intelligent screen recording of video, and the display direction of the recorded screen during video playback will change with the posture of the electronic device during the recording process. And changes cannot remain stable and consistent. [0003] That is to say, when the display direction of the screen of the current electronic device is changed during the video recording process, the recorded video images cannot be linked and processed so as to maintain the consistency of the display direction of the entire video content. For example, in the process of using a smartphone to record vertically, if the smartphone is rotated 90 de...
