Embodiment 1

[0023] refer to figure 1 , shows a flow chart of a video shooting method according to Embodiment 1 of the present invention.

[0024] The video shooting method of the embodiment of the present invention comprises the following steps:

[0025] Step 101: Determine the shooting subject.

[0026] The video shooting method of the embodiment of the present invention is applicable to a mobile terminal with a first camera and a second camera. When shooting a video, only any one of the cameras can be controlled to shoot, and of course two cameras can also be controlled to shoot at the same time. This is not specifically limited in the embodiments of the invention. If you control two cameras to shoot video at the same time, you need to correct the two cameras before shooting the video.

[0027] The video shooting method provided by the present invention mainly distinguishes the shooting subject from the surrounding scenery, that is, the shooting sub-body, and allows the main body and...

Embodiment 2

[0038] refer to figure 2 , shows a flowchart of a video shooting method according to Embodiment 2 of the present invention.

[0039] The video shooting method provided by the embodiment of the present invention is applied to a mobile terminal having a first camera and a second camera, and the mobile terminal simultaneously controls the first camera and the second camera to perform video shooting respectively during the video shooting process. Before video shooting, since the two cameras are controlled simultaneously for video shooting, dual camera correction is required to make the video images recorded by the two cameras the same.

[0040] There are many ways to correct the dual camera. For example, the structure of the two cameras on the device is fixed. After taking pictures of the same scene, comparing the position deviation of the two pictures of the same scene, and then cutting out the deviation respectively, two The same purpose as the picture taken by the author.

...

Embodiment 3

[0071] refer to image 3 , shows a flowchart of a video shooting method according to Embodiment 3 of the present invention.

[0072] The video shooting method provided by the embodiment of the present invention can be applied to a mobile terminal including one or more cameras. In the embodiment of the present invention, the mobile terminal controls a camera to perform video shooting during the video shooting process as an example. The video shooting method of the present invention Be explained.

[0073] The video shooting method provided by the embodiment of the present invention specifically includes the following procedures:

[0074] Step 301: Determine the shooting subject.

[0075] The video shooting method provided by the embodiment of the present invention is mainly to distinguish the video main body and the video sub-body in the video picture, that is, the scenery around the video main body, so that the shooting main body and the shooting sub-body can be interestingly...

Abstract

The present invention provides a video shooting method and a mobile terminal. The video shooting method is applied to a mobile terminal with a first camera and a second camera. The method includes: determining the shooting subject; receiving a video shooting instruction from a mobile terminal user Carrying out video shooting, tracking the subject during shooting, and generating first video image data and second video image data; performing image synthesis on the first video image data and second video image data to generate target video. Through the video shooting scheme provided by the present invention, it is possible to record a video in which the time of the shooting subject and the surrounding objects in the picture is not synchronized.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a video shooting method and a mobile terminal. Background technique [0002] At present, the video recording mode on the mobile terminal is relatively single, and the video recording modes currently provided by the mobile terminal include: a normal video recording mode, a fast video recording mode and a slow video recording mode. [0003] The working principle of normal recording mode is: the recording frame rate is the same as the video playback frame rate (for example, the recording video frame rate is 30fps, and the playback frame rate is also 30fps), which will synchronize the video screen with the actual recording screen time. The working principle of the fast recording mode is: record at a low frame rate, but play the video at a high frame rate (for example, the frame rate of the recorded video is 5fp, but the frame rate of the video playback is 30fps, and ...
