Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein.
It is understood that the execution subject of the embodiment of the present application may be an electronic device such as a smart phone or a tablet computer. The electronic device may be any device that includes an encoder, such as a video encoder.
Referring to fig. 1, fig. 1 is a schematic flowchart of a first process of an electronic device control method according to an embodiment of the present application, where the process may include:
101. and acquiring the operating parameters of the electronic equipment.
With the development of technology, more and more components are configured in electronic devices. For example, the components related to Image Processing include a Central Processing Unit (CPU), an Image Signal Processor (ISP), a Neural-Network Processing Unit (NPU), a Graphics Processing Unit (GPU), and the like. However, when the electronic device operates these components, the electronic device consumes much power and generates heat.
In the embodiment of the present application, for example, before or during the encoding operation performed by the electronic device, the electronic device may acquire the operating parameter.
In some embodiments, the encoding operations may include video encoding and the like.
After the operation parameters of the electronic device are acquired, the electronic device may detect whether the operation parameters satisfy preset conditions.
If the operating parameters are detected not to meet the preset conditions, the electronic equipment can continue to perform the encoding operation according to the current mode.
If the operating parameters are detected to satisfy the predetermined conditions, the process flow 102 may be entered.
102. If the operation parameter meets a preset condition, the complexity of the encoding operation performed by the electronic equipment is reduced, and the condition that the operation parameter meets the preset condition indicates that the electronic equipment is in at least one of the following states: a state requiring a limit on power consumption, a state requiring a limit on heat generation, and a state requiring allocation of at least one application among a set of system resources.
For example, if the electronic device detects that the operation parameter satisfies the preset condition, the electronic device may reduce the complexity of performing the encoding operation. The condition that the operating parameter of the electronic device satisfies the preset condition may indicate that the electronic device is in at least one of the following states: a state requiring a limitation of power consumption, a state requiring a limitation of heat generation, and a state requiring a centralized allocation of system resources to at least one application.
For example, the electronic device detects that the electronic device is in a low power state according to the operation parameter, that is, the electronic device is in a state that power consumption needs to be limited. In this case, the electronic device may reduce the complexity of performing the encoding operation.
For another example, the electronic device detects that the electronic device is in a state of high heat generation according to the operation parameter, that is, the electronic device is in a state of needing to limit heat generation. In this case, the electronic device may reduce the complexity of performing the encoding operation.
For another example, the electronic device detects that the electronic device is in a state where power and computational resources need to be allocated to a certain application or module in a centralized manner according to the operating parameters. In this case, the electronic device may reduce the complexity of performing the encoding operation.
It can be understood that, in the embodiment of the present application, the electronic device may first acquire the operating parameter. Then, if it is detected that the operating parameter of the electronic device satisfies the preset condition, the electronic device may reduce the complexity of performing the encoding operation. The condition that the operation parameter meets the preset condition can indicate that the electronic equipment is in at least one of the following states: a state requiring a limit on power consumption, a state requiring a limit on heat generation, and a state requiring allocation of at least one application among a set of system resources. Since the encoding operation may cause higher power consumption and device heating, and the embodiment of the present application may reduce the complexity of the encoding operation when the electronic device is in at least one of the three states, that is, the state in which power consumption needs to be limited, the state in which heating needs to be limited, and the state in which system resources need to be collectively allocated to at least one application, the embodiment of the present application may reduce power consumption and heating of the electronic device.
In one embodiment, the process of acquiring the operating parameters of the electronic device may include: and acquiring a residual electric quantity value of the electronic equipment.
Then, if the operation parameter satisfies the preset condition, the process of reducing the complexity of the encoding operation performed by the electronic device may include: and if the residual electric quantity value is smaller than the first threshold value, reducing the complexity of the coding operation of the electronic equipment, wherein the fact that the electronic equipment is in a state that the electric quantity consumption needs to be limited is indicated by the fact that the residual electric quantity value is smaller than the first threshold value.
For example, before or during the encoding operation, the electronic device may obtain a residual electric quantity value thereof, and detect whether the residual electric quantity value is smaller than the first threshold.
If the remaining power value is detected to be greater than or equal to the first threshold value, the power of the electronic device can be considered to be sufficient. In this case, the electronic device may continue to perform the encoding operation in the current manner.
If the remaining power value is detected to be smaller than the first threshold, the electronic device may be considered to be in a power shortage state, that is, the electronic device is in a state in which power consumption needs to be limited. In this case, the electronic device may reduce the complexity of the encoding operation, thereby saving power by reducing the complexity of the encoding operation. Since the complexity of the encoding operation can be reduced to reduce the workload of the devices related to the encoding operation, the heat generation of these devices can be reduced, and the heat generation of the entire electronic apparatus can be reduced.
In another embodiment, the process of acquiring the operating parameters of the electronic device may include: the temperature of the electronic device is acquired.
Then, if the operation parameter satisfies a preset condition, the process of reducing the complexity of the encoding operation performed by the electronic device may include: and if the temperature of the electronic equipment is greater than a second threshold value, the complexity of the coding operation performed by the electronic equipment is reduced, wherein the temperature greater than the second threshold value indicates that the electronic equipment is in a state that the heating is required to be limited.
For example, before or during the encoding operation, the electronic device may obtain a temperature of the at least one component and detect whether the temperature is greater than the second threshold.
If the temperature is detected to be less than or equal to the second threshold, the temperature of the electronic device may be deemed low. In this case, the electronic device may continue to perform the encoding operation in the current manner.
If it is detected that the temperature is greater than the second threshold, it may be determined that the electronic device is in a state in which heat generation is severe, that is, the electronic device is in a state in which heat generation needs to be limited. In this case, the electronic device may reduce the complexity of the encoding operation, so as to reduce the workload of the devices related to the encoding operation by reducing the complexity of the encoding operation, and thus achieve the effect of reducing the overall heat generation of the electronic device by reducing the heat generation of the devices. In addition, reducing the workload of the components associated with the encoding operation may also save power for the electronic device.
It should be noted that, in the embodiment of the present application, the temperature acquired by the electronic device may be the temperature of at least one of the following components: a battery, a dynamic random access memory controller DRAM, a central processing unit CPU, a graphics processing unit GPU, a neural network processor NPU, an image signal processor ISP, a digital signal processor DSP, an electronic device shell and the like.
In yet another embodiment, the electronic device may set different priorities for different applications in advance. Wherein, higher priority of the application may indicate that the application has higher demand on system resources (such as power, computational resources, etc.).
Based on this, the process of obtaining the operating parameters of the electronic device may include: the priority of the applications running in the electronic device is obtained.
Then, if the operation parameter satisfies a preset condition, the process of reducing the complexity of the encoding operation performed by the electronic device may include: and if a second application with higher priority than the first application exists in the running applications, reducing the complexity of the encoding operation performed by the electronic equipment, wherein the first application is the application performing the encoding operation, and the second application with higher priority than the first application exists in the running applications, which indicates that the electronic equipment is in a state that the system resources are required to be allocated to the second application in a centralized manner.
For example, at time T1, the electronic device is running a first application that performs an encoding operation. And at the time T2 after a period of time, the electronic equipment starts to run the second application. Wherein the priority of the second application is higher than the priority of the first application. Since the second application has a higher priority than the first application, the second application may be considered to have a higher demand for system resources than the first application, and the electronic device may be in a state that requires allocation of system resources to the second application in the set. In this case, the electronic device may reduce the complexity of the encoding operation, thereby reducing power consumption and device heating by reducing the complexity of the encoding operation and leaving more power and computational resources for the second application.
Referring to fig. 2, fig. 2 is a schematic flow chart of a control method of an electronic device according to an embodiment of the present application, where the flow chart includes:
201. and acquiring the operating parameters of the electronic equipment.
For example, the electronic device may obtain the operating parameters before or during the encoding operation.
Thereafter, the electronic device may detect whether its operating parameters satisfy a preset condition. The condition that the operating parameter of the electronic device satisfies the preset condition may indicate that the electronic device is in at least one of the following states: a state requiring a limitation of power consumption, a state requiring a limitation of heat generation, and a state requiring a centralized allocation of system resources to at least one application.
If the operation parameters are detected not to meet the preset conditions, the electronic equipment can continue to perform the coding operation according to the current mode.
If the operating parameters are detected to satisfy the predetermined conditions, then the process flow of 202 may be entered.
202. If the operation parameter meets a preset condition, reducing the complexity of the encoding operation performed by the electronic equipment by using a first type of operation, wherein the condition that the operation parameter meets the preset condition indicates that the electronic equipment is in at least one of the following states: a state requiring a limitation of power consumption, a state requiring a limitation of heat generation, and a state requiring a distribution of a set of system resources to at least one application, the first type of operation comprising at least one of: reducing the number of reference frames when performing motion estimation, increasing the merge level when performing motion estimation, compressing to I-frames, compressing to P-frames of a single reference frame, compressing to non-referenced frames.
For example, if the electronic device detects that its operating parameters satisfy a predetermined condition, the electronic device may use the first type of operation to reduce the complexity of performing the encoding operation. Wherein the first type of operation may include at least one of: reducing the number of reference frames when motion estimation is performed, increasing the merging level when motion estimation is performed, compressing into I-frames, compressing into P-frames of a single reference frame, compressing into non-referenced frames.
It should be noted that reducing the number of reference frames during Motion Estimation (ME) can increase the number of frames that need not be referred to, because the electronic device will not write the reconstructed pixel data of the frames that need not be referred to into a Dynamic Random Access Memory (DRAM). Therefore, reducing the number of reference frames reduces the power consumption of the DRAM, and the reconstructed frame DMA does not need to be operated, and the power consumption is reduced by the number of seeks. It will be appreciated that the overall heat generation of the electronic device may also be reduced, since reducing the workload of the motion estimation ME may reduce the heat generation of the relevant components.
Increasing the Merge Level (Merge Level) when performing motion estimation may enable the electronic device to save a portion of the energy of motion estimation. The compression into I-frames may allow the electronics to completely omit the energy of motion estimation. The adaptation of a P frame to a single reference frame may result in the electronic device only needing to expend the energy of motion estimation once. The compression to be unreferenced frames may allow the electronic device to save the energy of entropy coding. It can be understood that, since the above operation can reduce the workload of the related components and the battery discharge while saving the power consumption of the electronic device, thereby reducing the heat generation of the related components and the battery, the overall heat generation of the electronic device can also be reduced.
It should be noted that the first type of operation may refer to an operation performed on the image Frame (Frame) level to reduce the encoding complexity. That is, the first type of operation belongs to a frame-level or Slice-level operation. In addition to the above-listed operations, the present embodiment is not specifically limited and listed, as the operations for reducing the encoding complexity that can be performed on the image frame level belong to the first type of operations.
In one implementation, the embodiments of the present application may further include:
before encoding each image frame, if the operation parameters of the electronic equipment are detected to meet the preset conditions, determining first encoding parameters for the image frame by using a first type of operation;
encoding each image block in the image frame by using the first encoding parameter until each image block in the image frame is encoded;
or, before encoding each image slice, if it is detected that the operating parameters of the electronic device satisfy a preset condition, determining second encoding parameters for the image slice by using a first type of operation;
and encoding each image block in the image slice by using the second encoding parameter until each image block in the image slice is encoded.
For example, before encoding each image frame, the electronic device may detect whether its operating parameters satisfy a predetermined condition.
If the operation parameters are detected not to meet the preset conditions, the electronic equipment can carry out coding operation according to the current mode.
If the operating parameter is detected to satisfy the preset condition, the electronic device may determine a first encoding parameter for reducing encoding complexity for the image frame using a first type of operation. Then, the electronic device may encode each image block in the image frame by using the first encoding parameter until each image block in the image frame is encoded. The above-described process may be as shown in fig. 3.
Alternatively, before encoding each image Slice (Slice), the electronic device may detect whether its operating parameters satisfy preset conditions.
If the operation parameters are detected not to meet the preset conditions, the electronic equipment can carry out coding operation according to the current mode.
If it is detected that the operational parameters satisfy the preset condition, the electronic device may determine a second encoding parameter for reducing encoding complexity for the image slice using the first type of operation. Then, the electronic device may encode each image block in the image slice by using the second encoding parameter until each image block in the image slice is encoded, and the above process may be as shown in fig. 4.
It is understood that the operating parameters of the electronic device may change from time to time. For example, the power of the electronic device at this moment is still lower than the first threshold, but at the next moment, the user may have quickly charged the electronic device, so that the power of the electronic device is no longer lower than the first threshold. In this case, the operating parameters of the electronic device may change from meeting the preset conditions to no longer meeting the preset conditions. Therefore, the electronic device can detect whether the operation parameters of the electronic device meet the preset conditions before each image frame or image slice is coded, and decide whether the coding complexity needs to be reduced according to the detection result. Therefore, the embodiment of the application can adaptively determine whether the encoding complexity needs to be reduced according to the actual operating parameters of the electronic device.
In some embodiments, before encoding each image frame, a process of encoding a frame header (FrameHeader) to obtain a corresponding code stream may also be included. After all the image blocks in the image frame are encoded, a post-processing (PostProcessing) process may be further included to the code stream obtained after the frame header is encoded. The above-described process may be as shown in fig. 5.
In some embodiments, before encoding each image slice, a flow of encoding a slice header (SliceHeader) to obtain a corresponding code stream may be further included. After all the image blocks in the image slice are coded, the method can also comprise a flow of post-processing the code stream obtained after the slice header is coded. The above-described process may be as shown in fig. 6.
Referring to fig. 7, fig. 7 is a seventh flowchart illustrating an electronic device control method according to an embodiment of the present application, where the flowchart may include:
301. and acquiring the operating parameters of the electronic equipment.
For example, the electronic device may obtain the operating parameters before or during the encoding operation.
The electronic device may then detect whether its operating parameters satisfy a predetermined condition. The condition that the operating parameter of the electronic device satisfies the preset condition may indicate that the electronic device is in at least one of the following states: a state requiring a limitation of power consumption, a state requiring a limitation of heat generation, and a state requiring a centralized allocation of system resources to at least one application.
If the operation parameters are detected not to meet the preset conditions, the electronic equipment can continue to perform the coding operation according to the current mode.
If the operating parameters are detected to satisfy the predetermined conditions, the process flow 302 may be entered.
302. If the operation parameter meets a preset condition, reducing the complexity of the encoding operation performed by the electronic equipment by using a second type of operation, wherein the condition that the operation parameter meets the preset condition indicates that the electronic equipment is in at least one of the following states: a state requiring a limitation of power consumption, a state requiring a limitation of heat generation, and a state requiring allocation of a set of system resources to at least one application, the second type of operation comprising at least one of: in the mode comparison loop, the shape of the comparison block is reduced, the comparison of frequency domain conversion and inverse conversion types is reduced, the inter prediction mode is reduced, the intra prediction mode is reduced, and the prediction number of the block is reduced.
For example, if the electronic device detects that its operating parameters satisfy a predetermined condition, the electronic device may use a second type of operation to reduce the complexity of performing the encoding operation. Wherein the second type of operation may include at least one of: in the mode comparison loop, the shape of the comparison block is reduced, the comparison of frequency domain conversion and inverse conversion types is reduced, the inter prediction mode is reduced, the intra prediction mode is reduced, and the prediction number of the block is reduced.
It should be noted that the mode comparison loop in the video encoder is a large power consumption and heat source. A Mode comparison loop (ComparisonLoop) composed of a Forward Transform and Quantization (FTQ), a reverse Quantization and Transform (De-Quantization & inv. Transform, DQIT), a picture Block region Reconstruction (Block Reconstruction, blkRec), an Intra Prediction (Intra Prediction, intra p), an Intra Block Copy (Intra bc), a Motion Compensation (Motion Compensation, MC), a Mode Decision (Mode Decision, MD) and the like can compare and refer to various Prediction Block sizes, prediction modes, transform Block sizes, transform Block modes, and the like. Since the conversion circuit involved in the mode comparison loop consumes very much power, the embodiments of the present application can effectively reduce power consumption and heat generation by at least one of the following operations: in the mode comparison loop, the shape of the comparison block is reduced, the comparison of frequency domain conversion and inverse conversion types is reduced, the inter prediction mode is reduced, the intra prediction mode is reduced, and the prediction number of the block is reduced.
It should be noted that the second type of operation may refer to an operation performed on the layer of image blocks (blocks) to reduce the encoding complexity. That is, the second type of operation belongs to a Block (Block) level operation. In addition to the operations listed above, the operations that can be performed on the image block level to reduce the encoding complexity all belong to the second type of operations, and this embodiment is not specifically limited to this one.
In one embodiment, when performing the encoding operation, all the encoded image blocks within the same image frame may use the same encoding parameters, or all the encoded image blocks within the same image slice may use the same encoding parameters.
It can be understood that, the same encoding parameters are used for all the image blocks to be encoded in the same image frame or the same image slice, which can greatly reduce the workload of encoding operation and reduce the operation burden of the electronic device, thereby greatly reducing the power consumption and heat generation of the electronic device.
In another embodiment, if the electronic device determines the encoding parameters for each image block separately, the encoding parameters are controlled to remain unchanged during the encoding of the image block after determining the encoding parameters for the image block to be encoded during the encoding operation.
For example, in video coding, a video is composed of a plurality of image frames (frames), and each image Frame is composed of a plurality of image blocks (blocks). Each image frame may comprise at least one image slice, each image slice in turn may comprise a plurality of image blocks. In video encoding, an electronic device encodes each image Block (Block) in each image frame. In this embodiment, if the electronic device determines the encoding parameters for each image block individually, the encoding parameters are controlled to remain unchanged when the image block is encoded after determining the encoding parameters for the image block to be encoded.
For example, the electronic device reduces the complexity of the encoding operation by reducing the number of operations of the pattern comparison loop. For example, when an image block is encoded without reducing the complexity of the encoding operation, the number of operations of the mode comparison circuit is 8. When the operation parameters are detected to meet the preset conditions, the operation times of the mode comparison loop can be reduced from 8 times to 4 times when the electronic equipment encodes the image block, so that the effect of reducing the complexity of the encoding operation of the electronic equipment is achieved. After the number of operations of the pattern comparison circuit is determined to be 4 for the image block to be encoded, the number of operations of the pattern comparison circuit is kept unchanged for 4 times when the image block is encoded, and the number of operations is not suddenly changed to 5 times or 3 times, and the like. In this way, the workload of the electronic device mode comparison circuit is reduced, thereby achieving the effect of reducing the power consumption and heat generation of the electronic device.
In one implementation, the embodiments of the present application may include:
before each image block in the image frame is coded, if the operation parameters of the electronic equipment are detected to meet the preset conditions, determining third coding parameters for the image block by using a second type of operation;
and encoding the image block by using the third encoding parameter.
For example, in the case of using the second type of operation to reduce the encoding complexity, the electronic device may detect whether its operating parameters satisfy a preset condition before encoding each image block in each image frame.
If the operation parameters are detected not to meet the preset conditions, the electronic equipment can carry out coding operation according to the current mode.
If the operating parameters are detected to satisfy the preset condition, the electronic device may determine, for the image block, a third encoding parameter for reducing encoding complexity using a second type of operation. The electronic device may then encode the image block using the third encoding parameter without changing the encoding parameter. The above-described process may be as shown in fig. 8.
It is understood that the operating parameters of the electronic device may change from time to time. For example, the power of the electronic device at this moment is still lower than the first threshold, but at the next moment, the user may quickly charge the electronic device, so that the power of the electronic device is no longer lower than the first threshold. In this case, the operating parameters of the electronic device may change from meeting the preset conditions to no longer meeting the preset conditions. Therefore, the electronic device may detect whether the operating parameters of the electronic device satisfy the preset condition before encoding each image block in the image frame, and determine whether to reduce the encoding complexity according to the detection result. Therefore, the embodiment of the application can adaptively determine whether the encoding complexity needs to be reduced according to the actual operating parameters of the electronic device.
In some embodiments, before encoding each image frame, a process of encoding a frame header (FrameHeader) or a slice header (SliceHeader) to obtain a corresponding code stream may also be included. After all the image blocks in the image frame are coded, the method also can comprise a flow of post-processing the code stream obtained after the frame header or the slice header is coded. The above-described flow may be as shown in fig. 9.
In another implementation, the embodiment of the present application may further include the following process:
if the complexity of the encoding operation is reduced by using the first type of operation and the second type of operation, detecting whether the operating parameters of the electronic equipment meet preset conditions before encoding each image frame;
if the operation parameters of the electronic equipment are detected to meet the preset conditions, determining fourth encoding parameters for the image frames by using the first type of operation;
before each image block in the image frame is coded, if the operation parameters of the electronic equipment are detected to meet the preset conditions, determining fifth coding parameters for the image block by using the second type of operation;
and encoding the image block by using the fourth encoding parameter and the fifth encoding parameter.
For example, the electronic device may use the first type of operation and the second type of operation simultaneously to reduce the complexity of the encoding operation, i.e., the electronic device may reduce the complexity of the encoding operation at the image frame/slice level and at the image block level simultaneously.
Based on this, before encoding each image frame, the electronic device may first detect whether its operating parameters satisfy a preset condition.
If the operation parameters are detected not to meet the preset conditions, the electronic equipment can carry out coding operation according to the current mode. For example, the electronic device does not reduce encoding complexity.
If it is detected that the operating parameter meets a preset condition, the electronic device may first determine a fourth encoding parameter for the image frame to be encoded using a first type of operation. After the fourth encoding parameter used in the image frame level is determined, before each image block in the image frame to be encoded is encoded, the electronic device may further detect whether the operating parameter of the electronic device meets the preset condition. If it is detected that the operating parameters thereof still satisfy the preset conditions, the electronic device may determine fifth encoding parameters for the image block using a second type of operation. The electronic device may then encode the image block using the fourth encoding parameter and the fifth encoding parameter. The above process may be as shown in fig. 10.
For example, before encoding the image frame a, the electronic device may first detect whether its operating parameters satisfy a preset condition.
If the operation parameters are detected not to meet the preset conditions, the electronic equipment can carry out coding operation according to the current mode. For example, the electronic device does not reduce the encoding complexity.
If it is detected that the operating parameter meets the preset condition, the electronic device may first determine the fourth encoding parameter C1 for the image frame a using the first type of operation.
After determining the fourth encoding parameter used in the image frame level, before encoding the first image block a1 in the image frame a, the electronic device may further detect whether the operating parameter of the electronic device meets the preset condition again. If it is detected that the operating parameters still satisfy the preset conditions, the electronic device may determine the fifth encoding parameters D1 for the image block a1 using the second type of operation. Thereafter, the electronic device may encode the image block a1 using the fourth encoding parameter C1 and the fifth encoding parameter D1.
Then, before encoding the second image block a2 in the image frame a, the electronic device may further detect whether the operating parameter thereof satisfies the preset condition. If it is detected that the operating parameters thereof still satisfy the preset conditions, the electronic device may determine the fifth encoding parameters D2 for the image block a2 using the second type of operation. Thereafter, the electronic device may encode the image block a2 using the fourth encoding parameter C1 and the fifth encoding parameter D2.
That is, the fourth encoding parameter is applicable to the entire image frame currently being encoded, and the fifth encoding parameter is applicable to the image block currently being encoded in the image frame.
In some embodiments, before encoding each image frame, a process of encoding a frame header (FrameHeader) or a slice header (SliceHeader) to obtain a corresponding code stream may further be included. After all the image blocks in the image frame are coded, the method also can comprise a flow of post-processing the code stream obtained after the frame header or the slice header is coded. The above process may be as shown in fig. 11.
In one embodiment, the electronic device may decide whether to use the first type of operation to reduce the encoding complexity or the second type of operation to reduce the encoding complexity or both the first type of operation and the second type of operation to reduce the encoding complexity according to the current computing power.
For example, when the computing power of the electronic device is less than the third threshold, that is, the computing power of the electronic device is poor, only the first type of operation may be used to reduce the encoding complexity. For example, in a case that the computing capability of the electronic device is poor, when the electronic device performs an encoding operation, all the image blocks to be encoded within the same image frame use the same encoding parameters, or all the image blocks to be encoded within the same image slice use the same encoding parameters.
When the computing power of the electronic device is greater than or equal to the third threshold and less than the fourth threshold, i.e., the computing power of the electronic device is medium, the first type of operation and the second type of operation may be used simultaneously to reduce the encoding complexity. For example, in the case of the electronic device having a moderate arithmetic capability, when the electronic device performs an encoding operation, all of the image blocks to be encoded within the same image frame/image slice use the same encoding parameters, and the electronic device may determine the encoding parameters for each image block and control the encoding parameters to remain unchanged when encoding the image block.
When the computing power of the electronic device is greater than or equal to the fourth threshold, that is, the computing power of the electronic device is strong, only the second type of operation may be used at the same time to reduce the encoding complexity. For example, in a case where the computing power of the electronic device is strong, the electronic device may determine the encoding parameters for each image block individually, and control the encoding parameters to remain unchanged when encoding the image block.
Referring to fig. 12 to 14, fig. 12 to 14 are schematic views of scenes of an electronic device control method according to an embodiment of the present application.
For example, the electronic device starts video encoding at time T3. At time T4, the electronic device detects that the remaining power is lower than the first threshold, that is, the electronic device is in a low power state. At this time, the electronic device may generate a prompt message for prompting the user that the current remaining power is low, as shown in fig. 12. In the case where the electronic device is in a low power state, the electronic device can reduce the complexity of the encoding operation, thereby reducing power consumption and heat generation.
As another example, the electronic device starts video encoding at time T5. At time T6, the electronic device detects that the battery temperature is higher than the second threshold, i.e., the electronic device is in a state where the battery is heated more severely. At this time, the electronic device may generate a prompt message for prompting the user that the current battery temperature is high, as shown in fig. 13. Under the condition that the battery of the electronic equipment generates heat seriously, the electronic equipment can reduce the complexity of coding operation, thereby reducing the power consumption and the heat generation.
For another example, the electronic device starts video encoding at time T7. At time T8, the electronic device detects that the user clicked on gaming application Y, as shown in FIG. 14. Because the game application has higher requirements on system resources, the electronic equipment can reduce the complexity of coding operation, thereby reducing the power consumption and heating, and reserving more power, operation resources and the like for the game application.
