Description

Method, device and system for configuring camera configuration parameters of terminal equipment

Technical Field

The present disclosure relates to the field of internet technologies, and in particular, to a method, an apparatus, and a system for configuring camera configuration parameters of a terminal device.

Background

With the rapid development of the short video and live broadcast industries, the use frequency of the camera function of the terminal equipment is greatly increased. When a user takes a video using camera functionality within various applications (e.g., short video applications, live applications, social applications), the configuration parameters (e.g., resolution and frame rate) set for the camera directly affect the quality of the video and the user experience. If the set resolution and frame rate are too low, the captured video may be blurred. If the set resolution and frame rate are too high and the hardware configuration of the terminal device is low, the phenomena of application blocking, application flash back and the like can occur when the camera function is used. The models of terminal devices with camera functions vary widely, and it is necessary to select the most appropriate camera resolution and frame rate for different models, so that a user can smoothly use the camera functions and produce high-quality videos.

If the function of the camera or the application uses one configuration parameter for all models of terminal devices, only a uniform and low configuration parameter can be set for the model of terminal device with poor hardware performance, so that the terminal device with high hardware performance cannot produce high-quality video. In the related art scheme, models of various terminal devices on the market are counted and tested manually, and different camera parameter configurations are selected for the various models. However, when a new model comes on the market, manual procurement and testing are required. If the performance of the old terminal equipment is reduced, the camera configuration parameters for the old terminal equipment also need to be manually adjusted downwards, so that a large amount of labor cost is needed.

Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

For example, "include at least one of a and B" includes the following three cases in parallel: (1) comprises A; (2) comprises B; (3) including a and B.

Fig. 1 illustrates a system environment of a camera parameter configuration method according to an exemplary embodiment of the present disclosure. As shown in FIG. 1, the system environment may include a plurality of terminal devices 100-1, 100-2, … 100-n, a server 200. Here, the terminal device 100 may be a terminal device having a communication function and a camera function, for example, the terminal device 100 in the embodiment of the present disclosure may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, a netbook, a Personal Digital Assistant (PDA), an Augmented Reality (AR)/Virtual Reality (VR) device. Various applications using a camera function, such as a short video application, a live application, a social application, a video conference application, an online education application, and the like, may be run on the terminal device 100. When the terminal device 100 is running these applications and using the camera function, it connects and communicates with the server 200 through the network, thereby using the corresponding service provided by the server 200.

According to the exemplary embodiment of the present disclosure, the plurality of terminal devices 100-1, 100-2, … 100-n may send performance data about a video recorded when the video is recorded to the server 200 through the network, so that the server 200 may obtain big data about performance exhibited when cameras of the terminal devices 100 of the same model record the video, and may further perform a decision according to the big data to obtain a camera parameter configuration that can achieve the best performance for a certain model of terminal device. For example, for a particular model of smartphone, the server 200 may collect thousands of performance data about the videos that the smartphone records when recording short videos, and determine from the collected big data the best camera configuration parameters for that model of smartphone. A method of configuring camera configuration parameters performed at a terminal device and a method of determining camera configuration parameters performed at a server will be described below with reference to fig. 2 and 3, respectively.

Fig. 2 illustrates a flowchart of a camera parameter configuration method performed by a terminal device according to an exemplary embodiment of the present disclosure. In the following description, a smartphone is described as an example of a terminal device, but the present disclosure is not limited thereto. The camera parameter configuration method according to an exemplary embodiment of the present disclosure may be performed by an application installed in a terminal device when using a camera function.

Specifically, first, in step S201, when the terminal device 100 captures a video using a camera, performance data of the video recorded by the camera of the terminal device is recorded.

For example, when a user opens a short video application to record a short video, the short video application may record performance data of the recorded video. According to an exemplary embodiment of the present disclosure, the performance data of the video may include at least frame rate information of the video, model information of the terminal device, and frame time information of the video. For example, when the terminal device 100 records a video using a short video application, the short video application may record a frame rate, a model of the terminal device, and frame time information of each frame of the video in a recording process. Here, the time information of each frame of the video may be time stamp information of each video frame formed when the video is encoded. For example, if the user takes a short video with the application "fast hand" on the iPhone11 and uploads it to the server, the recorded performance data may be "iPhone 11,30fps, Timestamp [ i ]", where iPhone11 indicates the model of the terminal device, 30fps indicates the frame rate of the video, and Timestamp [ i ] indicates the Timestamp of the video frame with sequence number i.

According to an exemplary embodiment of the present disclosure, the video recorded by the terminal device 100 may be a real-time video transmitted to the server synchronously or a non-real-time video uploaded to the server after the recording is finished. For example, when video live broadcasting is performed using a camera of the terminal apparatus 100 and a live broadcasting application, the video recorded by the terminal apparatus 100 is real-time video, and when video is recorded using the camera of the terminal apparatus 100 and the recorded video is uploaded to a server after the recording of the video is completed, the video recorded by the terminal apparatus 100 is non-real-time video.

Next, in step S203, the performance data of the recorded video is transmitted to the server by the terminal device 100. As described above, the performance data of the recorded video may be transmitted to the server according to a predetermined protocol through the communication unit of the terminal device 100. For example, the terminal device 100 may access the network 300 (e.g., a mobile communication network of 3G, 4G, 5G) through the communication unit, so that an application using a camera function running on the terminal device 100 may transmit the performance data to the server through a preset protocol such as an HTTP protocol.

According to an exemplary embodiment of the present disclosure, when a user records a real-time video using the terminal device 100, performance data of the recorded video may be transmitted to a server at predetermined intervals. For example, recorded performance data about the video may be sent to the server every 5 seconds. When a video recorded by a user using the terminal device 100 is a non-real-time video, the recorded performance data of the video may be transmitted to the server after the recording of the video is completed. It should be understood that the timing of transmitting the performance data of the video is not limited to the above manner, and the performance data on the real-time video may be transmitted after the recording of the real-time video is finished, or the performance data may be transmitted at a predetermined interval while the non-real-time video is recorded.

In this way, after the server receives performance data on videos from a plurality of terminal apparatuses 100, the camera configuration parameters for the terminal apparatuses 100 can be determined from big data of the performance data on videos recorded by terminal apparatuses of the same model. The process of determining the camera configuration parameters will be described in detail later with reference to fig. 4.

Then, the terminal device 100 receives the camera configuration parameters from the server 200 and configures the camera of the terminal device 100 according to the received camera configuration parameters at step S205.

When the received camera configuration parameters are not changed, the terminal device 100 may not do any operation. When the received camera configuration parameters are higher or lower than the current camera configuration parameters, according to an exemplary embodiment of the present disclosure, step S205 may run the camera function using the configured camera parameters when the camera function is restarted. For example, the configured camera parameters may be used when the user records the video again after stopping the recording of the video. It should be understood that the exemplary embodiments of the present disclosure are not limited thereto, and for example, the user may be asked whether the camera parameters need to be reconfigured when the user records a video, and the timing for configuring the camera parameters may be determined according to the user's selection.

According to an exemplary embodiment of the present disclosure, the camera configuration parameters of the terminal device 100 include at least a frame rate and a resolution when the camera captures a video. The size of a picture in a video frame is in units of pixels, and the resolution is how many pixels are in each of the length and width of the picture, for example, 720 × 1080, which indicates that the width is 720 pixels and the height is 1080 pixels, and the higher the resolution is, the sharper the video is. The unit of the frame rate is fps (frame per second), and the higher the frame rate is, the smoother the video is. It should be understood that the camera configuration parameters may also include other parameters such as color space parameters, white balance, HDR, etc., which are not limited by the exemplary embodiments of the present disclosure.

Alternatively, according to an exemplary embodiment of the present disclosure, the camera configuration parameters may be divided into a plurality of gears, and the camera of the terminal device 100 is configured to operate in one of the plurality of gears according to its hardware parameters. For example, 7 camera parameter configuration gears may be set, having the following resolution and frame rate from the lowest gear L0 to the highest gear L6, respectively:

l0: resolution ratio: 540 × 960, frame rate: at a rate of 30fps to 30fps,

l1: resolution ratio: 720 × 1080, frame rate: at a rate of 30fps to 30fps,

l2: resolution ratio: 1080 × 1920, frame rate: at a rate of 30fps to 30fps,

l3: resolution ratio: 1440 × 2560, frame rate: at a rate of 30fps to 30fps,

l4: resolution ratio: 2160 × 4096, frame rate: at a rate of 24fps, the first,

l5: resolution ratio: 2160 × 3740, frame rate: at a rate of 30fps to 30fps,

l6: resolution ratio: 2160 × 4096, frame rate: 30 fps.

If the hardware of the camera of the terminal device 100 supports recording of a video with a resolution of 1440 × 2560 and a frame rate of 30fps, the gears of the camera configuration parameters of the terminal device 100 can be four gears L0 to L3.

A method of determining camera configuration parameters of the terminal device 100, which is performed by the server 200 according to an exemplary embodiment of the present disclosure, will be described below with reference to fig. 3.

According to an exemplary embodiment of the present disclosure, the server 200 may be a server for providing a video-related service. For example, the server 200 may be a server that provides services related to a short video application, a live application, a social application, a video conference application, an instant messaging application, or an online education application. The server 200 can acquire various information from the terminal device 100 by performing communication interaction with an application installed in the terminal device 100.

As shown in fig. 3, in step S301, performance data of a video recorded by the terminal apparatus 100 when the video is recorded is received from the terminal apparatus 100, and the performance data of the video received from the terminal apparatus 100 is stored.

As described above, the application on the terminal device 100 may record performance data of a video when recording the video and transmit the performance data to the server. The server 200 may receive performance data from a plurality of terminal devices 100-1, 100-2, 100-3, … 100-n and store the received performance data in a database, so that large data on performance data of various models of terminal devices may be formed.

Next, in step S303, big data of performance data on videos recorded by a plurality of terminal devices of the same model of the terminal device is read, and camera configuration parameters for the terminal device are determined from the read big data.

As described above, the server 200 can receive performance data recorded when recording video from a plurality of terminal apparatuses 100, so that large data on performance exhibited when recording video of the same model of terminal apparatus 100 can be counted. According to an exemplary embodiment of the disclosure, the performance data of the video at least comprises frame rate information of the video, model information of the terminal device and frame time information of the video, and the camera configuration parameters at least comprise a frame rate and a resolution of the video recorded by the camera.

According to an exemplary embodiment of the present disclosure, the camera configuration parameters for a terminal device 100 of the same model may be determined according to the katon rate of videos recorded by a plurality of terminal devices 100 of the model. Here, the seizure rate corresponding to a certain model of terminal device refers to a ratio of occurrence of seizure of videos recorded by the terminal device under the same camera parameter configuration, which is obtained through big data statistics.

For example, according to an exemplary embodiment of the present disclosure, the stuck rate is the total number of times that a plurality of terminal devices of the same model have stuck in a video recorded under the same camera parameter configuration/the number of times that the plurality of terminal devices record the video. For example, if performance data of 100 videos is received from 100 terminal apparatuses 100 of the same model, the server 200 may determine the number of times of hitching occurring in the 100 videos from the performance data of the 100 videos. According to an exemplary embodiment of the present disclosure, a case where an interval of frames continuously occurring n times in one recorded video is greater than a threshold corresponding to a frame rate of the video may be determined as one pause occurring in the recorded video. For example, if it is determined from the frame rate information that the frame rate of a video is set to 30fps, the frame interval thereof should be 1/30 seconds (about 33ms), and if it is determined from the frame time information on the video (e.g., the time stamp of each frame) in the performance data at this time that the interval of three consecutive frames in the video exceeds the threshold (e.g., 200ms), it is determined that a pause occurs in the video. Thus, the click rate can be calculated as the sum of the number of times of click-through occurring in 100 videos/the number of times of video recording (i.e., 100). That is, if the number of times of katon occurrence in 100 videos is 5, the katon rate determined for the terminal device 100 is 5/100 ═ 0.05.

It should be understood that the morton rate is only an example of an index for determining the camera configuration parameters, and those skilled in the art may determine the camera configuration parameters for the terminal device using other indices calculated from the big data of the performance data of the video as needed.

According to an exemplary embodiment of the present disclosure, in step S303, in response to the katon rate being greater than the threshold, it is determined to decrease the camera configuration parameters of the terminal device 100; in response to the katton rate being less than or equal to the threshold, it is determined to increase the camera configuration parameters of the terminal device 100. For example, the threshold value of the stuck rate is preset to 0.02, it is determined that the camera configuration parameter corresponding to the terminal device 100 needs to be decreased when the calculated stuck rate corresponding to the terminal device 100 is higher than 0.02, and it is determined that the camera configuration parameter corresponding to the terminal device 100 can be increased if the stuck rate is lower than 0.02.
