Embodiment 1

[0065] An embodiment of the present invention provides a video data processing method based on dual cameras.

[0066] The execution subject of this embodiment is a mobile terminal with dual cameras.

[0067] The mobile terminal may be a terminal device such as a smart phone or a tablet computer. The dual cameras can be located on the front or back of the mobile terminal at the same time, or can be located on the front and back of the mobile terminal respectively.

[0068] When the dual cameras are respectively located on the front and back of the mobile terminal, at least one of the dual cameras can adjust the viewing angle by rotating, stretching, folding, etc., so that the viewing ranges of the dual cameras are the same or basically the same, so that the captured images captured by the dual cameras can be captured by the dual cameras. Depth data of the subject.

[0069] The video data processing method based on dual camera of the present invention is described below in con...

Embodiment 2

[0092] In order to make the present invention more clear, this embodiment further describes the steps of synthesizing time-still video data. In this embodiment, the time-still video data only includes pictures of the target object moving in a still environment, and does not include the motion track of the target object.

[0093] Figure 5 is a flow chart of steps for synthesizing time-still video data according to the second embodiment of the present invention.

[0094] Step S510, copying the static video image to obtain multiple frames of the static video image with the same number of frames as the dynamic video data.

[0095] According to the number of image frames contained in the dynamic video data, the static video image is copied, so that the frame number of the static video image is the same as that of the image in the dynamic video data.

[0096] In step S520, according to the position data and depth data of the target object in each frame of image, the target object...

Embodiment 3

[0112] This embodiment provides a video data processing device based on dual cameras. The video data processing apparatus based on dual cameras in this embodiment can be set in a mobile terminal with dual cameras.

[0113] Such as Figure 8 Shown is a structural diagram of a video data processing device based on dual cameras according to a third embodiment of the present invention.

[0114] The video data processing device based on dual cameras includes:

[0115] The calling module 810 is used for calling the video data captured by the dual cameras.

[0116] The selection module 820 is configured to select a target object and a frame of still video image in the video data.

[0117] The extracting module 830 is configured to extract dynamic video data of the target object from the video data.

[0118] A synthesis module 840, configured to synthesize the static video image and the dynamic video data to obtain time-still video data of the target object.

[0119] In one embod...

Abstract

The invention discloses a video data processing method and device based on double cameras. The method comprises the steps of calling the double cameras to photograph video data; selecting a target object and a frame of static video image from the video data; extracting dynamic video data corresponding to the target object from the video data; synthesizing the static video image and the dynamic video data, thereby obtaining time static video data of the target object. According to the method and the device, the dynamic video data of the target object in the video data is extracted, the dynamic target object is synthesized into the static video image according to depth of filed data, further a dynamic and static combined special effect image is obtained, and a scene that the dynamic target object shuttles freely in a time static environment is built. According to the method and the device, a user does not need to have specialized knowledge, the special effect image can be photographed through the mobile terminal with the double cameras, the photographing is convenient, the operation complexity is low, and the device cost and labor cost are low.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a video data processing method and device based on dual cameras. Background technique [0002] With the continuous development of mobile terminal technology, mobile terminals can take pictures, shoot videos, record data, query information and control other terminal devices. Therefore, mobile terminals rely on powerful functions and have become an indispensable part of people's daily life. [0003] At present, when using mobile terminals to shoot video data, the definition is high, which can efficiently restore the images collected by users and record users' lives. However, the existing mobile terminals are unable to shoot pictures with special effects combining motion and stillness, and furthermore, the existing mobile terminals cannot meet the personalized needs of users. For example: in a video picture, the user wants the target object to be in a moving state ...
