detailed description

In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the embodiments of the present invention in detail through specific implementations in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

Example one:

In order to solve the problem that the video recording parameters are consistent and will not change during the entire video recording process in some cases, resulting in poor video effects and poor user experience, an embodiment of the present invention provides a video recording method. , By performing video recording when a video recording instruction is received, further, during the video recording process, adjust the video recording parameters according to the current recording environment, and further, perform video recording according to the adjusted video recording parameters; see As shown in FIG. 1, FIG. 1 is a schematic diagram of the basic flow of the video recording method provided by this embodiment.

S101: When a video recording instruction is received, perform video recording.

It should be understood that the video recording instruction in this embodiment can be issued by the user clicking or pressing a physical button, or it can be issued by the user clicking or pressing a virtual button, or it can be issued by a non-touch screen, such as voice. It can be. It is worth noting that in practical applications, it can be flexibly adjusted according to specific application scenarios. As long as it belongs to the way in which video recording instructions can be issued, all are within the protection scope of the present invention, and the present invention does not limit this.

S102: During the video recording process, adjust the video recording parameters according to the current recording environment.

In an example, the video recording parameters in this embodiment include but are not limited to exposure time, frame rate, contrast, and saturation, where the video recording parameters include any one or any combination of exposure time, frame rate, contrast, and saturation. form. It is worth noting that, here are just a few common video recording parameters, which can be flexibly adjusted according to specific application scenarios in actual applications.

In an example, the adjustment of the video recording parameters according to the current recording environment in this embodiment includes at least the following two ways:

Method 1: Adjust the video recording parameters according to the picture movement rate of the current recording environment.

In an example, the video recording parameters are adjusted according to the picture movement rate of the current recording environment, including:

Obtain the picture movement rate of the current recording environment, determine the target recording parameters according to the picture movement rate and the picture movement rate-target recording parameter mapping table, and adjust the current video recording parameters according to the target recording parameters.

In some examples, the frame movement rate of the current recording environment can be acquired by acquiring image frames, and performing image recognition on the acquired image frames, such as a difference method. It is worth noting that the present invention is not limited to this method, as long as it belongs to the method that can determine the picture movement rate of the current recording environment, it is within the protection scope of the present invention.

It should be understood that the picture movement rate-target recording parameter mapping table is pre-stored on the terminal. For a better understanding, a specific example is used for illustration, for example, see Table 1:

Table I

Screen movement rate	Exposure time	Frame rate	Contrast	saturation
below a2	K1	N1	M1	Q1
a2～a3	K2	N2	M2	Q2
a4～a5	K3	N3	M3	Q3
a6～a7	K4	N4	M4	Q4
above a7	K5	N5	M5	Q5

According to the above table 1, the video recording parameters include exposure time, frame rate, contrast, and saturation. The slower the picture movement rate (a2<a3<a4<a5<a6<a7) corresponds to the larger the exposure time (K1 >K2>K3>K4>K5>K6>K7), the smaller the frame rate (N1<N2<N3<N4<N5<N6<N7), the smaller the contrast (M1<M2<M3<M4<M5<M6< M7), the smaller the saturation (Q1<Q2<Q3<Q4<Q5<Q6<Q7).

In an example, the obtained screen movement rate can also be judged to determine whether it belongs to a non-moving scene or a moving scene, where the screen movement rate is less than the preset threshold corresponding to the non-moving scene, and the screen movement rate greater than the preset threshold corresponds to Mobile scenarios, for example, see Table 2:

Table II

Scenes	Moving rate	Exposure time	Frame rate	Contrast	saturation
Unmoved scene	below a5	K1	N1	M1	Q1
Mobile scene	above a5	K2	N2	M2	Q2

According to Table 2 above, the video recording parameters include exposure time, frame rate, contrast, and saturation. Among them, the picture movement rate below a5 corresponds to the unmoved scene, and the picture movement rate above a5 corresponds to the moving scene, and the exposure time is K1 >K2, frame rate N1<N2, contrast M1<M2, saturation Q1<Q2.

It is worth noting that the above list is only two examples of the picture movement rate-target recording parameter mapping table. In actual applications, the picture movement rate-target recording parameter mapping table is flexibly set by the developer based on experiments or experience.

Method 2: Adjust the video recording parameters according to the brightness value of the current recording environment.

In an example, the video recording parameters are adjusted according to the brightness value of the current recording environment, including:

Obtain the brightness value of the current recording environment, determine the target recording parameter according to the brightness value and the brightness value-target recording parameter mapping table, and adjust the current video recording parameter according to the target recording parameter.

In some examples, the brightness value of the current recording environment can be obtained by collecting image frames to perform image recognition on the collected image frames; in other examples, the brightness value of the current recording environment can be obtained by determining the brightness value of the current recording environment through a photosensitive sensor. Brightness value. It should be noted that the present invention is not limited to these two methods, as long as it belongs to the method that can determine the brightness value of the current recording environment, it is within the protection scope of the present invention.

It should be understood that the picture movement rate-target recording parameter mapping table is pre-stored on the terminal,

For a better understanding, here is a specific example for illustration, for example, see Table 3:

Table Three

Brightness value	Exposure time	Frame rate	Contrast	saturation
below b2	K1	N1	M1	Q1
b2～b3	K2	N2	M2	Q2
b4～b5	K3	N3	M3	Q3
b6～b7	K4	N4	M4	Q4
above b7	K5	N5	M5	Q5

According to the above table 3, the video recording parameters include exposure time, frame rate, contrast, and saturation. The smaller the brightness value (b2<b3<b4<b5<b6<b7) corresponds to the larger the exposure time (K1> K2>K3>K4>K5>K6>K7), the smaller the frame rate (N1<N2<N3<N4<N5<N6<N7), the smaller the contrast (M1<M2<M3<M4<M5<M6<M7) ), the smaller the saturation (Q1<Q2<Q3<Q4<Q5<Q6<Q7).

In an example, the obtained brightness value of the current recording environment can also be judged to determine whether it belongs to a night scene or a daytime scene, where the brightness value is less than the preset threshold value corresponding to the night scene, and the brightness value greater than the preset threshold value corresponds to the daytime scene. Scenarios, for example, see Table 4:

Table Four

Scenes	Brightness value	Exposure time	Frame rate	Contrast	saturation
Night scene	below b5	K1	N1	M1	Q1
Daytime scene	above b5	K2	N2	M2	Q2

According to the above table 4, the video recording parameters include exposure time, frame rate, contrast, and saturation. Among them, the brightness value below b5 corresponds to the night scene, and the brightness value above b5 corresponds to the day scene, and the exposure time is K1>K2. Frame rate N1<N2, contrast M1<M2, saturation Q1<Q2.

It is worth noting that the above listed are only two examples of brightness value-target recording parameter mapping tables. In actual applications, the brightness value-target recording parameter mapping tables can be flexibly set by the developer based on experiments or experience.

It should be understood that method 1 and method 2 can be executed separately or at the same time. When executed at the same time, for example, the video recording parameter values obtained from Table 1 and Table 2 may be different. In this case, it can be obtained from Table 1. The video recording parameter values in Table 2 shall prevail, or the video recording parameter values obtained in Table 2 shall prevail, or the average value of the obtained video recording parameter values in Table 1 and Table 2 may be taken or other calculations can be carried out. .

S103: Perform video recording according to the adjusted video recording parameters.

In this embodiment, video recording is performed according to the adjusted video recording parameters.

For a better understanding, here is still an example for explanation:

For example, as shown in Table 2, suppose that the terminal starts video recording with the video recording parameters corresponding to the moving scene, that is, when receiving a video recording instruction for video recording, the corresponding exposure time is K2, the frame rate is N2, and the contrast It is M2 and the saturation is Q2. The current environment is monitored and it is found that the current scene is not moving. At this time, the exposure time is automatically adjusted to K1, the frame rate is N1, the contrast is M1, and the saturation is Q1, because the exposure time is K1>K2. Frame rate N1<N2, contrast M1<M2, saturation Q1<Q2, so the automatic adjustment at this time is to increase the exposure time, reduce the frame rate, reduce the contrast, reduce the saturation, and further, according to the exposure time K1, frame rate N1, contrast M1, saturation Q1 for video recording; it should be understood that when it is detected that the current environment is in a moving scene, the exposure time is automatically adjusted to K2, the frame rate is N2, and the contrast is M2. , The saturation is Q2, and the automatic adjustment at this time is to reduce the exposure time, increase the frame rate, increase the contrast, and increase the saturation. Furthermore, according to the exposure time K2, the frame rate N2, the contrast M2, and the saturation Q2 Make video recording.

For another example, referring to Table 4, suppose that the terminal starts video recording with the video recording parameters corresponding to the daytime scene, that is, when receiving a video recording instruction to perform video recording, the corresponding exposure time is K2, and the frame rate is N2. The contrast is M2 and the saturation is Q2. The current environment is monitored and it is found that it is currently in a night scene. At this time, the exposure time is automatically adjusted to K1, the frame rate is N1, the contrast is M1, and the saturation is Q1, because the exposure time is K1>K2. Frame rate N1<N2, contrast M1<M2, saturation Q1<Q2, so the automatic adjustment at this time is to increase the exposure time, reduce the frame rate, reduce the contrast, reduce the saturation, and further, according to the exposure time K1, frame rate N1, contrast M1, saturation Q1 for video recording; it should be understood that when it is detected that the current environment is in a daytime scene, the exposure time is automatically adjusted to K2, the frame rate is N2, and the contrast is M2. , The saturation is Q2, and the automatic adjustment at this time is to reduce the exposure time, increase the frame rate, increase the contrast, and increase the saturation. Furthermore, according to the exposure time K2, the frame rate N2, the contrast M2, and the saturation Q2 Make video recording.

The video recording method provided by the embodiment of the present invention performs video recording when a video recording instruction is received. Further, during the video recording process, the video recording parameters are adjusted according to the current recording environment, and further, according to the adjusted Video recording parameters are used for video recording; it solves the problem that the video recording parameters are consistent and will not change during the entire video recording process in some cases, resulting in poor video effects and poor user experience. That is, in the video recording method provided by the embodiments of the present invention, the current video recording parameters are adjusted in real time according to the current recording environment during the video recording process, and then the video recording is performed according to the adjusted video recording parameters. Combined with the dynamic adjustment of video recording parameters in the current recording environment, the effect of video recording is greatly improved, thereby enhancing user experience satisfaction.

At the same time, the video recording method provided by the embodiments of the present invention, especially when the video recording parameters include exposure time and frame rate, are dynamically adjusted in real time according to the current recording environment, and the video recording parameter exposure time can effectively improve the definition of the video screen. , Video shooting effect, in terms of video recording parameter frame rate, it can effectively reduce the transmission bit rate of subsequent video uploads, reduce bandwidth waste, and further improve user experience satisfaction.

Embodiment two:

In order to solve the problem that the video recording parameters are consistent and will not change during the entire video recording process in some cases, resulting in poor video effects and poor user experience, an apparatus is provided in an embodiment of the present invention. Refer to FIG. 2, which is a schematic structural diagram of the apparatus provided in this embodiment:

The device provided in this embodiment includes a recording module 201 and an adjustment module 202;

Wherein, the recording module 201 is configured to perform video recording when a video recording instruction is received;

Wherein, the adjustment module 202 is used to adjust the video recording parameters according to the current recording environment during the video recording process;

It should be understood that the recording module 201 is also configured to perform video recording according to the adjusted video recording parameters.

It should be understood that the recording module 201 and the adjustment module 202 in this embodiment include but are not limited to being implemented by a processor or other hardware devices.

In an example, the video recording parameters in this embodiment include but are not limited to exposure time, frame rate, contrast, and saturation, where the video recording parameters include any one or any combination of exposure time, frame rate, contrast, and saturation. form. It is worth noting that, here are just a few common video recording parameters, which can be flexibly adjusted according to specific application scenarios in actual applications.

In an example, the adjustment module 202 in this embodiment adjusts the video recording parameters according to the current recording environment, including at least the following two ways:

Manner 1: The adjustment module 202 adjusts the video recording parameters according to the picture movement rate of the current recording environment.

In an example, the adjustment module 202 obtains the picture movement rate of the current recording environment, determines the target recording parameters according to the picture movement rate and the picture movement rate-target recording parameter mapping table, and adjusts the current video recording parameters according to the target recording parameters.

In an example, the adjustment module 202 can acquire the frame movement rate of the current recording environment by acquiring image frames, and perform image recognition, such as a difference method, on the acquired image frames.

Manner 2: The adjustment module 202 adjusts the video recording parameters according to the brightness value of the current recording environment.

In an example, the adjustment module 202 obtains the brightness value of the current recording environment, determines the target recording parameter according to the brightness value and the brightness value-target recording parameter mapping table, and adjusts the current video recording parameter according to the target recording parameter.

In an example, the adjustment module 202 may acquire the brightness value of the current recording environment by acquiring image frames to perform image recognition on the acquired image frames.

In an example, the adjustment module 202 can obtain the brightness value of the current recording environment by using a photosensitive sensor to determine the brightness value of the current recording environment.

In this embodiment, the video recording parameters including exposure time, frame rate, contrast, and saturation are taken as examples. The slower the picture movement rate, the greater the exposure time, the smaller the frame rate, the lower the contrast, and the lower the saturation. , The smaller the brightness value corresponds to the larger the exposure time, the smaller the frame rate, the smaller the contrast, and the smaller the saturation.

It is worth noting that, in order not to cumbersome description, this embodiment does not fully describe all the examples in the first embodiment, and it should be clear that all the examples in the first embodiment are applicable to this embodiment.

The device provided by the embodiment of the present invention performs video recording when receiving a video recording instruction through the recording module. Further, the adjustment module adjusts the video recording parameters according to the current recording environment during the video recording process, and further, the recording module adjusts the video recording parameters according to the current recording environment. The adjusted video recording parameters are used for video recording; it solves the problem that the video recording parameters are consistent and will not change during the entire video recording process in some cases, resulting in poor video effects and poor user experience. That is, during the video recording process, the device provided by the embodiment of the present invention adjusts the current video recording parameters in real time according to the current recording environment, and then performs video recording according to the adjusted video recording parameters, which realizes the combination of the current video recording process and the current video recording parameters. The dynamic adjustment of video recording parameters in the recording environment has greatly improved the effect of video recording, thereby enhancing user experience satisfaction.

The shooting effect, in terms of the video recording parameter frame rate, can effectively reduce the transmission bit rate of subsequent video uploads, reduce bandwidth waste, and further improve user experience satisfaction.

Example three:

The embodiment of the present invention provides a device on the basis of the second embodiment. Please refer to FIG. 3, which is a schematic structural diagram of the device provided in this embodiment:

The device provided in this embodiment includes a recording module 201 and an adjustment module 202. The adjustment module 202 includes a movement detection module 2021, an image sensor module 2022, and an encoder module 2023.

For a better understanding, this embodiment uses video recording parameters including exposure time and frame rate as examples.

In an example:

When the motion detection module 2021 detects that the picture in the current recording environment is not moving, it issues an instruction to the image sensor module 2022 to increase the exposure time per frame, and issues an instruction to the encoder module 2023 to reduce the frame rate.

Among them, after the image sensor module 2022 and the encoder module 2023 receive the instruction issued by the movement detection module 2021, they need to immediately stop the current operation, discard the current processed data, and then collect data and encode according to the new encoding method corresponding to the instruction.

The issuance of instructions is carried out in batches, each batch of instructions includes issuance to the image sensor module 2022 and the encoder module 2023, and the number of issued instructions can be determined according to actual usage scenarios.

E.g:

The first time an instruction is issued, the image sensor module 2022 increases the exposure time per frame to 100 milliseconds, and the encoder module 2023 reduces the frame rate to 10 frames per second.

The instruction is issued for the second time, the image sensor module 2022 increases the exposure time per frame to 200 milliseconds, and the encoder module 2023 reduces the frame rate to 5 frames per second.

The instruction is issued for the third time, the image sensor module 2022 increases the exposure time per frame to 500 milliseconds, and the encoder module 2023 reduces the frame rate to 2 frames per second.

In another example:

When the motion detection module 2021 detects that the picture in the current recording environment is moving, it issues an instruction to the image sensor module 2022 to reduce the exposure time of each frame, and issues an instruction to the encoder module 2023 to increase the frame rate.

Among them, after the image sensor module 2022 and the encoder module 2023 receive the instruction issued by the movement detection module 2021, they need to immediately stop the current operation, discard the current processed data, and then collect data and encode according to the new encoding method corresponding to the instruction.

The issuance of instructions is carried out in batches, and each batch of instructions includes the issuance to the image sensor module 2022 and the encoder module 2023, and the number of issued instructions can be determined according to the actual use scenario test experience.

E.g:

The first time an instruction is issued, the image sensor module 2022 reduces the exposure time per frame to 200 milliseconds, and the encoder module 2023 increases the frame rate to 5 frames per second.

The second time an instruction is issued, the image sensor module 2022 reduces the exposure time of each frame to 100 milliseconds, and the encoder module 2023 increases the frame rate to 10 frames per second.

The instruction is issued for the third time, the image sensor module 2022 reduces the exposure time per frame to 40 milliseconds, and the encoder module 2023 increases the frame rate to 25 frames per second.

It should be noted:

IDR: Instantaneous Decoding Refresh, abbreviated as I frame, key frame, intra-frame coded frame is an independent frame with all its own information, and can be decoded independently without referring to other images. The first frame in the video sequence is always I frame.

GOP: Group of picture, the period of the key frame, that is, the distance between two IDR frames.

P: Forward predictive coding frame.

In the above two examples, the motion detection module 2021 also needs to issue a key frame acquisition instruction to the encoder module 2023, that is, after the encoder module 2023 receives the key frame instruction, the first frame output by subsequent encoding is the key frame IDR, and The second frame does not need to be a key frame to be the forward predictive coding frame P, which needs to be determined according to the GOP in the actual application scenario.

Embodiment four:

The embodiment of the present invention provides a device on the basis of the second embodiment. Please refer to FIG. 4, which is a schematic structural diagram of the device provided in this embodiment:

The device provided in this embodiment includes a recording module 201 and an adjustment module 202. The adjustment module 202 includes a brightness detection module 2024, an image sensor module 2022, and an encoder module 2023.

For a better understanding, this embodiment uses video recording parameters including exposure time and frame rate as examples.

In an example:

When the brightness detection module 2024 detects that the current recording environment is a night scene, it issues an instruction to the image sensor module 2022 to increase the exposure time of each frame, and issues an instruction to the encoder module 2023 to reduce the frame rate.

Among them, after the image sensor module 2022 and the encoder module 2023 receive the instruction issued by the brightness detection module 2024, they need to immediately stop the current operation, discard the currently processed data, and then collect data and encode according to the new encoding method corresponding to the instruction.

The issuance of instructions is carried out in batches, each batch of instructions includes issuance to the image sensor module 2022 and the encoder module 2023, and the number of issued instructions can be determined according to actual usage scenarios.

E.g:

The first time an instruction is issued, the image sensor module 2022 increases the exposure time per frame to 100 milliseconds, and the encoder module 2023 reduces the frame rate to 10 frames per second.

The instruction is issued for the second time, the image sensor module 2022 increases the exposure time per frame to 200 milliseconds, and the encoder module 2023 reduces the frame rate to 5 frames per second.

The instruction is issued for the third time, the image sensor module 2022 increases the exposure time per frame to 500 milliseconds, and the encoder module 2023 reduces the frame rate to 2 frames per second.

In another example:

When the brightness detection module 2024 detects that the current recording environment is a daytime scene, it issues an instruction to the image sensor module 2022 to reduce the exposure time of each frame, and issues an instruction to the encoder module 2023 to increase the frame rate.

Among them, after the image sensor module 2022 and the encoder module 2023 receive the instruction issued by the brightness detection module 2024, they need to immediately stop the current operation, discard the currently processed data, and then collect data and encode according to the new encoding method corresponding to the instruction.

The issuance of instructions is carried out in batches, and each batch of instructions includes the issuance to the image sensor module 2022 and the encoder module 2023, and the number of issued instructions can be determined according to the actual use scenario test experience.

E.g:

The first time an instruction is issued, the image sensor module 2022 reduces the exposure time per frame to 200 milliseconds, and the encoder module 2023 increases the frame rate to 5 frames per second.

The second time an instruction is issued, the image sensor module 2022 reduces the exposure time of each frame to 100 milliseconds, and the encoder module 2023 increases the frame rate to 10 frames per second.

The instruction is issued for the third time, the image sensor module 2022 reduces the exposure time per frame to 40 milliseconds, and the encoder module 2023 increases the frame rate to 25 frames per second.

It should be noted:

IDR: Instantaneous Decoding Refresh, abbreviated as I frame, key frame, intra-frame coded frame is an independent frame with all its own information, which can be decoded independently without referring to other images. The first frame in the video sequence is always I frame.

GOP: Group of picture, the period of the key frame, that is, the distance between two IDR frames.

P: Forward predictive coding frame.

In the above two examples, the brightness detection module 2024 also needs to issue a key frame acquisition instruction to the encoder module 2023, that is, after the encoder module 2023 receives the key frame instruction, the first frame output by subsequent encoding is the key frame IDR. The second frame does not need to be a key frame to be the forward predictive coding frame P, which needs to be determined according to the GOP in the actual application scenario.
