The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of examples do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the present disclosure as recited in the appended claims.

The present disclosure relates to a video processing method. In a relevant processing method, anti jitter processing is performed on a video in a video recording stage, as illustrated in FIG. 1. FIG. 1 is an example diagram showing a video processing method in a related art. In a video anti jitter processing manner illustrated in FIG. 1, the anti jitter processing on an Mth image frame of the video is used as the example for description, t denotes time, and each image frame in a video to be recorded is acquired according to a time sequence. In order to perform the anti jitter processing on the Mth image frame of the video, it is necessary to continuously receive image data 101′ for Y frames of images, such as image data for the Mth image frame, image data for an (M+1)th image frame, . . . , till image data for an (M+Y−1)th image frame, and acquire Gyro data 102′ corresponding to the continuous Y frames of images, such as Gyro data corresponding to an mth image frame, Gyro data corresponding to an (m+1)th image frame, . . . , till Gyro data corresponding to an (m+Y−1)th image frame. The anti jitter processing 201′ is performed on the Mth image frame according to Y frames of Gyro data 102′ corresponding to the image data for the continuous Y frames of images. After the anti jitter processing, the image data for the Mth image frame is encoded. Then, the anti jitter processing is performed on the image data for the (M+1)th image frame, image data 103′ for the Y frames of images, such as image data for the (M+1)th image frame, image data for an (M+2)th image frame, . . . , till image data for an (M+Y)th image frame may continuously be received, and Y frames of Gyro data 104′ corresponding to the continuous Y frames of images, such as Gyro data corresponding to the (m+1)th image frame, Gyro data corresponding to the (m+2)th image frame, . . . , till Gyro data corresponding to the (m+Y)th image frame are acquired. The anti jitter processing is performed on the (M+1)th image frame according to the Gyro data 104′ corresponding to the continuous Y frames of images. After the anti jitter processing, the image data for the (M+1)th image frame is encoded, and so on, thereby completing the anti jitter processing on the recorded video. According to the above manner, to perform the anti jitter processing on a video book, the image data for the Y frames of images of the video to be recorded and the corresponding Y frames of Gyro data are at least stored, such that the required memory is large. Furthermore, since the anti jitter processing is completed in the video recording process, the power consumption of the electronic device is increased, and the electronic product is prone to heating.

According to a video processing method provided by the present disclosure, acquired image data for each image frame of a video to be recorded may directly be encoded to form encoded data for each image frame, parameter data of a motion parameter of an electronic device for performing the anti jitter processing on each image frame may be acquired, and an anti jitter processing policy for each image frame is determined according to the acquired parameter data of the motion parameter of the electronic device for performing the anti jitter processing on each image frame. In a video recording stage, the encoded data for each image frame of the video to be recorded and the corresponding anti jitter processing policy are stored as the corresponding frames of video files. In the video processing method provided by the present disclosure, only the parameter data of the motion parameter of the electronic device for correspondingly performing the anti jitter processing on each image frame may be cached in the video recording stage, and the corresponding number of image data may unnecessarily be cached, thereby reducing the memory occupation of the electronic device. Moreover, according to the video processing method provided by the present disclosure, the anti jitter processing is unnecessarily performed on the video to be recorded, such that the power consumption of the electronic device in the video recording process is reduced, and the heating state of the electronic product is reduced.

An embodiment of the present disclosure provides a video processing method. The video processing method is applied to an electronic device. FIG. 2 is a flow chart showing a video processing method according to an example. As illustrated in FIG. 2, the processing method is applied to a video recording process. The video processing method may include the following operations.

At S11, image data for an Nth image frame of a video to be recorded is acquired, and the N is a positive integer greater than or equal to 1.

At S12, the acquired image data for the Nth image frame is encoded to obtain encoded data for the Nth image frame.

At S13, x frames of parameter data of a motion parameter of an electronic device that are relevant to the Nth frame are acquired according to a preset rule, and the x is a positive integer greater than or equal to 1.

At S14, an anti jitter processing policy for the Nth image frame is determined according to the acquired x frames of parameter data of the motion parameter of the electronic device.

At S15, the encoded data for the Nth image frame and the anti jitter processing policy for the Nth image frame are stored as a video file for the Nth image frame.

The method is applied to the electronic device, such as a mobile phone, a portable android device (PAD), a tablet computer, and the like. When recording the video, the electronic device acquires the image data for the Nth image frame, and encodes the image data for the Nth image frame to obtain the encoded data for the Nth image frame. The x frames of parameter data of the motion parameter of the electronic device that are relevant to the Nth frame are acquired according to the preset rule; the anti jitter processing policy for the Nth image frame is determined according to the acquired x frames of parameter data of the motion parameter of the electronic device; and the encoded data for the Nth image frame and the anti-jitter processing policy for the Nth image frame are stored as the video file for the Nth image frame. The motion parameter of the electronic device refers to a motion parameter of the electronic device that affects the video recording in the video recording process. The motion parameter may include any motion parameter affecting the video recording, and may, for example, include at least one of: a motion direction parameter, a motion velocity parameter or a motion manner parameter. The parameter data of the motion parameter may be gyroscope data, i.e., the Gyro data.

According to the video processing method provided by the present disclosure, the corresponding number of image data may unnecessarily be cached in a video recording stage, thereby reducing the occupation of a memory of the electronic device. Moreover, the anti jitter processing is unnecessarily performed on the video to be recorded in the video recording stage, such that the power consumption of the electronic device in the video recording process is reduced, and the heating state of electronic product is reduced.

An embodiment of the present disclosure provides a video processing method. FIG. 3 is a method for acquiring x frames of parameter data of a motion parameter of an electronic device that are relevant to an Nth frame according to a preset rule at S13 in FIG. 2.

At S131, the x frames of parameter data of the motion parameter of the electronic device that are relevant to the Nth image frame are acquired according to either of following manners.

In a first manner, nth to (n+X−1)th frames of parameter data of the motion parameter of the electronic device that are corresponding to Nth to (N+X−1) frames of images are continuously acquired, and the X is a positive integer greater than or equal to 1.

In a second manner, according to an equal time interval from the Nth frame, the x frames of parameter data of the motion parameter of the electronic device that are corresponding to X frames of images are backwardly acquired, and the X is a positive integer greater than or equal to 1.

In the first manner, in order to accurately perform the anti jitter processing on the Nth image frame, the nth to (n+X−1)th frames of parameter data of the motion parameter of the electronic device that are corresponding to the Nth to (N+X−1)th frames of images are continuously and backwardly acquired along the time sequence from the Nth image frame, and the anti jitter processing policy for the Nth image frame is determined according to the acquired nth to (n+X−1)th frames of parameter data of the motion parameter of the electronic device. The X is equal to the x, and the nth to (n+X−1)th frames of parameter data of the motion parameter of the electronic device is the x frames of parameter data of the motion parameter of the electronic device.

In the second manner, in order to further reduce the cached data, on the basis of ensuring that the anti jitter policy for the Nth image frame can be accurately determined, the x frames of parameter data of the motion parameter of the electronic device that are corresponding to the X frames of images are backwardly acquired along the time sequence according to the equal time interval, and the anti jitter processing policy for the Nth image frame is determined according to the acquired X frames of parameter data of the motion parameter of the electronic device.

FIG. 4 is an example diagram showing a video processing method according to an example. The example diagram illustrated in FIG. 4 is the video processing method in the video recording process. In the example illustrated in FIG. 4, the x frames of parameter data of the motion parameter of the electronic device that are relevant to the Nth image frame are acquired according to the first manner. As illustrated in FIG. 4, whenever image data for one image frame is acquired, the image data is encoded to obtain encoded data for this image frame. For example, after the image data 101 for the Nth image frame is acquired, the image data is subjected to video encoding to obtain the encoded data N for the Nth image frame, and the encoded data is numbered as 102 in FIG. 4. The image data for the (N+1)th image frame is acquired, the image data is subjected to the video encoding to obtain the encoded data N+1 for the (N+1)th image frame, and so on; and each image frame of the video to be recorded is subjected to the video encoding to obtain the encoded data for each image frame. In order to accurately perform the anti jitter processing on each image frame of the video to be recorded, the x frames of parameter data of the motion parameter of the electronic device that are corresponding to the X frames of images are continuously and backwardly acquired along the time t sequence from the present image frame. The anti jitter processing policy for each image frame is determined according to the acquired corresponding parameter data of the motion parameter. Each frame of encoded data and the anti jitter processing policy for each image frame are stored as the video file for each image frame. For example, after the image data for the Nth image frame is acquired, the image data for the Nth image frame is encoded to obtain the encoded data N for the Nth image frame. In order to accurately perform the anti jitter processing on the Nth image frame, the nth to (n+X−1)th frames of data 103 of the motion parameter of the electronic device that are corresponding to the Nth to (N+X−1)th frames of images are continuously and backwardly acquired along the time t sequence from the Nth frame. The anti jitter processing policy for the Nth image frame is determined according to the acquired nth to (n+X−1)th frames of data 103 of the motion parameter of the electronic device. The encoded data N for the Nth image frame and the anti jitter processing policy for the Nth image frame are stored as the video file for the Nth image frame. After the image data for the (N+1)th image frame is acquired, the image data for the (N+1)th image frame is encoded to obtain the encoded data N+1 for the (N+1)th image frame. In order to accurately perform the anti jitter processing on the (N+1)th image frame, the (n+1)th to (n+X)th frames of parameter data of the motion parameter of the electronic device that are corresponding to the (N+1)th to (N+X)th frames of images are continuously and backwardly acquired along the time t sequence from the (N+1)th frame. The anti jitter processing policy for the (N+1)th image frame is determined according to the acquired (n+1)th to (n+X)th frames of parameter data of the motion parameter of the electronic device. The encoded data N+1 for the (N+1)th image frame and the anti jitter processing policy for the (N+1)th image frame are stored as the video file for the (N+1)th image frame. By the same reasoning, all video files of the video to be recorded are acquired.
