The present application claims priority of chinese patent application entitled "data transmission method, apparatus, device, and computer readable storage medium" filed by the national intellectual property office of the people's republic of china, application number 201711468103.0, on 29/12/2017, the entire contents of which are incorporated herein by reference.

Technical Field

The present invention relates to the field of network technologies, and in particular, to a data transmission method, apparatus, device, and computer-readable storage medium.

Background

Currently, in the Video monitoring industry, a Network environment includes a terminal, a Network Video Recorder (NVR), and an Internet Protocol Camera (IPC). When the IPC has a specified function and the terminal wants to instruct the IPC to execute a specified operation based on the specified function, a packet needs to be transmitted to the IPC so that the IPC executes the corresponding operation according to the packet.

The process of transmitting data packets between the terminal and the IPC usually needs to be processed and forwarded by NVR. Taking the device information configuration function as an example, the terminal generates a data packet and sends the data packet to the NVR, where the data packet carries NVR authentication information, an instruction number corresponding to the device information configuration function, and a code block for configuring device information. After receiving the data packet, the NVR analyzes the data packet to obtain NVR authentication information and an instruction number, the NVR authentication information is verified, when the verification is passed, a preset instruction table is inquired based on the instruction number and is used for recording instruction numbers corresponding to all functions supported by the NVR and corresponding processing instructions, when the NVR determines that the instruction number belongs to the preset instruction table, the NVR modifies the NVR authentication information in the data packet into IPC authentication information, the processing instructions corresponding to the instruction numbers are executed, the data packet is processed, the processed data packet is sent to the IPC, the IPC analyzes the data packet to obtain IPC authentication information and a code block for executing specified operation, the IPC authentication information is verified, and when the verification is passed, the code block is operated, and equipment information is configured. And when the NVR determines that the instruction number does not belong to the preset instruction list, a failure notice is returned to the terminal to inform the terminal that the transmission process of the data packet fails.

In the process of implementing the invention, the inventor finds that the related art has at least the following problems:

when the NVR does not support the designated function, namely the designated instruction number corresponding to the designated function and the processing instruction are not stored in the preset instruction table, the terminal cannot transmit the data packet to the IPC through the NVR, the IPC cannot use the designated function according to the data packet, and the limitation is strong. Particularly, when the IPC pushes a new function, the NVR must be upgraded once, the instruction number and the processing instruction of the new function are added in the preset instruction table, and then the IPC can execute the operation according to the data packet of the terminal based on the new function, so that the pushing of the new function of the IPC is restricted by the NVR version, and the use of the new function of the IPC is affected.

401. and the terminal sends the data packet to the video recording equipment.

In this embodiment, the video recording device is used as a forwarding device between the terminal and the image capturing device, and when the terminal wants to control the image capturing device to execute a specified operation based on a specified function, a data packet corresponding to the specified function is generated and sent to the video recording device, so that the video recording device forwards the data packet to the image capturing device.

Wherein the designated function includes at least one of a device information configuration function, a device operation control function, a device capability set acquisition function, and a device alarm function. The device information configuration function is a function of configuring own device information by the camera device according to the instruction of the terminal, the device operation control function is a function of executing corresponding operation by the camera device according to the instruction of the terminal, the device capability set acquisition function is a function of acquiring the capability set of the camera device and transmitting the capability set to the terminal, and the device alarm function is a function of alarming by the camera device according to the instruction of the terminal.

In order to indicate that the data packet is used for controlling the camera device to use the designated function, the terminal may carry a designated instruction identifier in the data packet, where the designated instruction identifier is used to instruct the camera device to perform a designated operation based on the designated function, and the terminal, the video device, and the camera device may pre-agree an instruction identifier corresponding to each function, so that when the terminal sends the data packet carrying the designated instruction identifier, the video device may know that the data packet is to be processed according to a processing instruction corresponding to the designated function, and the camera device may know that the designated function is to be used.

In a possible implementation manner, in order to improve the security of data transmission, the terminal may further carry second authentication information in the data packet, so that the video recording device performs verification according to the second authentication information. The second authentication information is used for the video equipment to check whether the terminal has the control authority over the video equipment, when the second authentication information carried by the terminal is correct, the video equipment can determine that the terminal has the control authority over the video equipment, and when the second authentication information carried by the terminal is wrong, the video equipment can determine that the terminal does not have the control authority over the video equipment. The second authentication information may be a user identifier and a login password of the video device, and the terminal may pre-store the second authentication information of the video device, so that the second authentication information may be obtained when the data packet is generated, and the second authentication information is added to the data packet.

In addition, in order to ensure that the video recording device knows the image pickup device to which the data packet needs to be transmitted, the terminal may determine in advance a channel number of each image pickup device to which the video recording device is connected, where the channel number is used to determine the corresponding image pickup device, and when the terminal wants to transmit the data packet to a certain image pickup device, the terminal may obtain the channel number of the image pickup device, and carry the channel number in the data packet, so that the video recording device determines the corresponding image pickup device according to the channel number and transmits the data packet to the image pickup device.

In practical application, the data packet may include two parts, namely a data packet header and a data packet, and the terminal may carry a specified instruction identifier, second authentication information and a channel number in the data packet header and carry a code block required for executing a specified operation in the data packet. In addition, the terminal may also carry other information in the header, such as a terminal IP address, a terminal MAC (Media Access Control) address, and the like.

Exemplarily, referring to fig. 5, which shows a frame format schematic diagram of a data packet, line 1 in fig. 5 represents a data packet header including various information such as a specified instruction identifier, second authentication information, a channel number, a terminal IP address, a terminal MAC address, and line 2 represents a data packet including a code block of a specified operation.

402. And when the video recording equipment receives the data packet, checking the second authentication information in the data packet.

When the video recording device receives the data packet, the video recording device may analyze the data packet to obtain second authentication information and a designated instruction identifier, check the second authentication information, perform the following step 403 according to the designated instruction identifier when the second authentication information passes the check, and directly discard the data packet when the second authentication information does not pass the check.

The video recording equipment can acquire the prestored second authentication information aiming at the process of verifying the second authentication information, compares the second authentication information in the data packet with the prestored second authentication information, and when the second authentication information in the data packet is the same as the prestored second authentication information, verifies that the second authentication information passes, and determines that the terminal has the control authority for the video recording equipment. And when the two are different, verifying that the second authentication information does not pass, and determining that the terminal does not have the control authority for the video equipment and is possibly illegal equipment.

It should be noted that the process of checking the second authentication information is only an optional way, and the video recording device may also perform the following step 403 directly according to the specified instruction identifier after parsing the data packet.

403. And when the video equipment determines that the specified function is not supported according to the specified instruction identifier in the data packet, the video equipment sends a retransmission instruction to the terminal.

The method includes that the video equipment determines a mode that the video equipment does not support the designated function according to a designated instruction identifier, the video equipment can store a preset instruction list, the preset instruction list is used for recording instruction numbers corresponding to all functions supported by the video equipment and corresponding processing instructions, and when the video equipment determines that the designated instruction numbers do not belong to the preset instruction list, the video equipment can determine that the video equipment does not support the designated function.

In this embodiment, when the video recording device determines that the video recording device does not support the designated function, a retransmission instruction may be sent to the terminal, where the retransmission instruction is used to instruct the terminal to send the data packet again in a transparent transmission manner, that is, to send a transparent transmission data packet in which the data packet is encapsulated.

Optionally, the video recording device may carry the first authentication information in the retransmission instruction, and when the terminal receives the retransmission instruction of the video recording device and obtains the first authentication information carried in the retransmission instruction, it may be known that the video recording device does not support the specified function, and the transparent transmission data packet may be generated according to the obtained first authentication information.

The first authentication information is used for the camera equipment to check whether the video equipment has the control authority over the camera equipment, when the first authentication information is correct, the camera equipment can determine that the video equipment has the control authority over the camera equipment, and when the first authentication information is wrong, the camera equipment can determine that the video equipment does not have the control authority over the camera equipment. In addition, the first authentication information may be used to notify the terminal that the video recording device does not support a specific function, and may be a user identifier and a login password of the video recording device.

With regard to the manner in which the video recording apparatus acquires the first authentication information, the video recording apparatus may store the first authentication information of at least one image pickup apparatus that has been connected in advance, and when it is determined that the specified function is not supported, select the first authentication information of the image pickup apparatus to which the packet needs to be transferred from the at least one piece of first authentication information. For example, the video recording device may store the correspondence between the channel number and the first authentication information, and may determine the corresponding first authentication information according to the channel number in the data packet.

In addition, when the video recording device determines that the specified function is supported according to the specified instruction identifier, for example, when the specified instruction identifier is determined to belong to a preset instruction table, the second authentication information in the data packet may be modified into the first authentication information, and a processing instruction corresponding to the specified instruction number may be executed to process the data packet, and the processed data packet is forwarded to the image pickup device.

Optionally, when the video recording device determines that the specified function is not supported, the received data packet may be discarded, or the data packet may be discarded after being cached for a certain period of time.

404. And when the terminal receives the retransmission instruction, assembling the data packet and the transparent transmission head to obtain a transparent transmission data packet, and sending the transparent transmission data packet to the video equipment.

By executing the above steps 401 to 403, the terminal may detect whether the video recording device supports the designated function by whether the video recording device returns the retransmission instruction in a manner of first sending the data packet once, so as to know whether the transparent transmission data packet needs to be sent. Therefore, when receiving the retransmission instruction, the terminal can know that the video recording device does not support the designated function, and needs to send the data packet in a transparent transmission mode again.

Optionally, when the retransmission instruction carries the first authentication information, the terminal may obtain the first authentication information carried by the retransmission instruction when analyzing the retransmission instruction, so as to assemble the transparent transmission data packet according to the originally sent data packet and the first authentication information.

The process of assembling the transparent transmission data packet may specifically include the following steps 4041 and 4043:

4041. and the terminal modifies the second authentication information in the data packet into the first authentication information.

In this embodiment, in order to improve the security of data transmission, the process of transmitting the data packet from the terminal to the image capturing device through the video recording device may actually include a plurality of verification processes: the video equipment checks whether the terminal has the control authority to the video equipment or not according to the second authentication information in the data packet, the data packet is transmitted to the camera equipment after the check is passed, the camera equipment checks whether the video equipment has the control authority to the camera equipment or not according to the first authentication information in the data packet, and the designated function is reused after the check is passed.

Then, in order to ensure that the first authentication information can be obtained when the camera device analyzes the data packet in the subsequent process, after receiving the first authentication information, the terminal may obtain the previously sent data packet, or regenerate the data packet, modify the second authentication information in the data packet into the first authentication information, obtain a modified data packet, and subsequently generate a transparent transmission data packet according to the modified data packet and the transparent transmission header.

4042. And the terminal generates a transparent transmission head carrying the transparent transmission processing instruction identifier.

In order to make the video recording device know that the data packet is transmitted in a transparent transmission manner, a transparent transmission processing instruction identifier is introduced in this embodiment, and the transparent transmission processing instruction identifier is used for instructing the video recording device to transmit the data packet in a transparent transmission manner. The terminal and the video equipment can agree in advance: when the terminal hopes that the video equipment transmits the data packet in a transparent transmission mode, a transparent transmission head carrying a transparent transmission processing instruction identification is assembled in front of the data packet, and when the video equipment analyzes the transparent transmission head to obtain the transparent transmission processing instruction identification, the data packet is transmitted to the camera equipment. The terminal and the video recording device may store the transparent transmission processing instruction identifier in advance, where the transparent transmission processing instruction identifier may be a specific character string including numbers, letters, symbols, and the like, and may be "0 xnnnn", for example.

In a possible implementation manner, in practical application, when the video recording device receives a data packet sent by the terminal, the second authentication information is obtained from the data packet for verification, and in order to achieve the effect that the video recording device does not need to analyze the data packet and directly transparently transmits the data packet in the subsequent process, the terminal can carry the second authentication information in the transparent transmission head, so that after the video recording device obtains the transparent transmission data packet, the second authentication information can be obtained by analyzing the transparent transmission head for verification, and the data packet behind the transparent transmission head can not be analyzed any more, so that the video recording device can be ensured to verify the second authentication information, and the video recording device can be prevented from analyzing the data packet.

Similarly, the channel number needs to be obtained from the data packet by the video recording device, so that the camera device to which the data packet needs to be transmitted can be obtained according to the channel number, the effect of directly transmitting the data packet is achieved without analyzing the data packet by the video recording device for the follow-up process, the terminal can also carry the channel number of the camera device in the transparent transmission head, and then after the video recording device obtains the transparent transmission data packet, the channel number can be obtained by analyzing the transparent transmission head, so that the corresponding camera device can be determined according to the channel number, the data packet after the transparent transmission head can not be analyzed any more, so that the video recording device can be ensured to successfully determine the receiving party of the data packet, and the video recording device can be prevented from analyzing the data packet.

The first point to be described is that, in order to further ensure that the video recording device does not parse the data packet but pass through the data packet in the subsequent process, the contents of the pass-through header of the pass-through data packet and the data packet header of the data packet sent for the first time may be the same except for the instruction identifier, that is, the terminal may modify the instruction identifier of the data packet header of the data packet sent for the first time from the specified instruction identifier to a pass-through processing instruction identifier, and directly use the modified data packet header as the generated pass-through header.

The second point to be described is that, in this embodiment, only step 4041 is described in the foregoing, and step 4042 is described later as an example, in practical application, the terminal may also execute step 4042 first and then execute step 4041, that is, generate the transparent header and then modify the data packet.

4043. And the terminal assembles the modified data packet and the generated transparent transmission head to obtain a transparent transmission data packet.

The terminal may add the generated transparent transmission header before the modified data packet to obtain the transparent transmission data packet. Illustratively, referring to fig. 6, which shows a schematic diagram of a frame format of a transparent transmission data packet, line 1 in fig. 6 represents a transparent transmission header, line 2 represents a data packet header of the data packet, and line 3 represents a data packet of the data packet.

405. And when the video equipment receives the transparent transmission data packet, verifying the second authentication information in the transparent transmission head.

When the video equipment receives the transparent transmission data packet, the transparent transmission head can be analyzed to obtain second authentication information and a transparent transmission processing instruction identifier, the second authentication information is verified, when the second authentication information is verified to be passed, the following step 406 is executed according to the transparent transmission processing instruction identifier, and when the second authentication information is not verified to be passed, the transparent transmission data packet is directly discarded.

The process of checking the second authentication information in the transparent transmission header is similar to the process of checking the second authentication information in the data packet header in step 402. The video recording equipment obtains the second authentication information from the transparent transmission head, so that the data packet behind the transparent transmission head cannot be further analyzed.

It should be noted that the process of checking the second authentication information is only an optional way, and the video recording device may also directly execute the following step 406 according to the specified instruction identifier after parsing the data packet.

406. And the video equipment transparently transmits the data packet to the camera equipment according to the transparent transmission processing instruction identifier.

In order to enable the video recording device to implement the function of transmitting the data packet to the image capturing device, in this embodiment, a transparent transmission processing instruction is introduced, the transparent transmission processing instruction is used for transmitting the data packet, a processing logic of a transparent transmission process may be encapsulated, for example, a code block of the transparent transmission data packet may be included, the video recording device may store the transparent transmission processing instruction in advance, and once the transparent transmission processing instruction is called, the process of transmitting the data packet may be executed.

In practical application, the video recording device may add the corresponding relationship between the transparent transmission processing instruction and the transparent transmission processing instruction identifier in advance in a stored preset instruction table, so that when the video recording device analyzes the transparent transmission head to obtain the transparent transmission processing instruction identifier, the preset instruction table is queried according to the transparent transmission processing instruction identifier, the transparent transmission processing instruction corresponding to the transparent transmission processing instruction identifier is determined from the preset instruction table, the transparent transmission processing instruction is executed, and the data packet is transmitted to the camera device.

In the process of transparently transmitting the data packet, the video recording equipment can strip the transparent transmission head from the transparently transmitted data packet to obtain the residual data packet and transparently transmit the data packet to the camera equipment because the transparently transmitted data packet consists of the transparent transmission head and the data packet.

It should be noted that, by adopting the above scheme to realize the process of transparently transmitting the data packet by the video equipment, the effect of not disturbing the original processing logic of the video equipment to the data packet can be achieved. This is because the original processing logic of the video recording device for each data packet may be: the method includes the steps of obtaining an instruction identifier from a data packet, determining a processing instruction corresponding to the instruction identifier in a preset instruction list, executing the processing instruction to process the data packet, and sending the processed data packet to the camera device, wherein in the embodiment, only the transparent transmission instruction identifier and the transparent transmission processing instruction need to be added to the original preset instruction list, and the processing logic of the transparent transmission function of the camera device can be guaranteed, namely: and acquiring a transparent transmission instruction identifier from the transparent transmission data packet, determining a transparent transmission processing instruction corresponding to the transparent transmission instruction identifier in a preset instruction table, executing the transparent transmission processing instruction to strip a transparent transmission head of the transparent transmission data packet, and sending the obtained data packet to the camera equipment. Therefore, the newly added transparent transmission function of the video equipment can be ensured, the video equipment can be compatible with the original processing logic, and the steps are simple and effective.

407. The camera device receives the transparent data packet and verifies the first authentication information in the data packet.

When the camera device receives the data packet, the camera device may analyze the data packet header of the data packet to obtain first authentication information and a designated instruction identifier, check the first authentication information, execute the following step 408 according to the designated instruction identifier when the first authentication information passes the check, and directly discard the data packet when the first authentication information fails the check.

The method comprises the steps that in the process of checking first authentication information for the camera device, the camera device can acquire the first authentication information stored in advance, the first authentication information in the data packet and the first authentication information stored in advance are compared, when the first authentication information and the first authentication information are the same, the first authentication information is checked to pass, and the video recording device is determined to have the control authority over the camera device. When the first authentication information and the second authentication information are different, the first authentication information is not verified, and the video recording equipment is determined to have no control authority for the camera equipment and possibly be illegal equipment.

It should be noted that the process of checking the first authentication information is only an optional way, and the video recording device may also perform the following step 408 directly according to the obtained specified instruction identifier after parsing the data packet.

408. And the camera equipment executes the specified operation based on the specified function according to the specified instruction identification and returns a feedback result to the video equipment.

In this embodiment, the camera device may encapsulate processing logic of various functions as each function interface in advance, and the terminal and the camera device may use a frame of RPC (Remote Procedure Call), so as to achieve an effect that the terminal remotely calls the function interface of the camera device and instructs the camera device to use a corresponding specified function.

Specifically, the terminal and the camera device may agree in advance a corresponding relationship between the instruction identifier and the functional interface, when the terminal wants to instruct the camera device to execute a specified operation based on a specified function, the specified instruction identifier corresponding to the specified function is carried in a data packet header of a data packet, and a code block required for calling the specified functional interface is carried in a data packet of the data packet, when the camera device receives the data packet through the video device, the data packet header is analyzed to obtain the specified instruction identifier, the functional interface corresponding to the specified instruction identifier is determined, the code block in the data packet is executed, and the specified operation instructed by the terminal is executed in a process of operating the functional interface.

Further, the image capturing apparatus may generate a feedback result after the specified operation is performed, and return the feedback result to the image recording apparatus, where the feedback result may include an operation state indicating whether the specified operation is performed this time successfully, and may be a success state or a failure state. Alternatively, the feedback result may include parameter information that is a parameter of the image pickup apparatus that the terminal wants to acquire.

Illustratively, this step 408 may include the following steps 4081-4084 for the particular type of function specified.

4081. The specified function is a device information configuration function:

when the designated function is the device information configuration function, the designated instruction identifier is the instruction identifier corresponding to the device information configuration function interface, and the camera device can operate the device information configuration function interface to configure the device information. The device information may include, among other things, the resolution, bit rate, frame rate, etc. of the image capturing device.

In one possible implementation, the code block in the data packet may carry target device information, so that the image capturing device configures the original device information as the target device information. For example, the image capturing apparatus may obtain target apparatus information from a code block of the data packet, transfer the target apparatus information into the apparatus information configuration function interface, run the apparatus information configuration function interface, and configure the original apparatus information as the target apparatus information. Taking the device information as an example of the resolution, assuming that the original resolution of the image capturing device is 960x576, and the data packet carries the target resolution 1280x960, the image capturing device configures the resolution to be 1280x 960.

After the image pickup device configuration device information is finished, if the configuration is successful, a first feedback result can be generated, wherein the operation state in the first feedback result is a success state, and the first feedback result is used for informing the terminal that the image pickup device has successfully configured the device information. If the configuration fails, a second feedback result may be generated, the operation state of which is a failure state, the second feedback result being used to notify the terminal that the image pickup apparatus configuration apparatus information fails.

4082. The specified function is a device operation control function:

when the designated function is the device operation control function, the designated instruction identifier is the instruction identifier corresponding to the device operation control function interface, and the camera device can run the device operation control function interface to execute the designated operation. The specified operation may be PTZ (Pan/Tilt/Zoom, Zoom control) operation, such as rotating at a certain angle, moving a certain distance, adjusting a focal length, and the like.

In a possible implementation manner, a code block in the data packet may carry parameters of the specified operation, and the image capturing apparatus may obtain the parameters of the specified operation from the code block, send the parameters of the specified operation into the apparatus operation control function interface, run the apparatus operation control function interface, and execute the specified operation. Taking the rotation at a certain angle as an example, assuming that the data packet carries 90 °, the image pickup apparatus rotates 90 °.

After the image pickup apparatus finishes executing the specified operation, if the execution is successful, a third feedback result may be generated, where an operation state in the third feedback result is a success state, and the third feedback result is used to notify the terminal that the image pickup apparatus has successfully executed the specified operation. If the execution fails, a fourth feedback result may be generated, the operation state of which is a failure state, the fourth feedback result being used to notify the terminal that the image pickup apparatus failed to execute the specified operation.

4083. The designated function is a device capability set acquisition function:

when the designated function is the device capability set acquisition function, the instruction identifier is designated, namely the instruction identifier corresponding to the device capability set acquisition function interface, and the camera device can operate the device capability set acquisition function interface to acquire the current capability set so as to feed the capability set back to the terminal subsequently. Here, the capability set may be used to indicate all parameters that the image capturing apparatus can configure, for example, the capability set may be { sensitivity, contrast, sharpness, saturation, … … }, and further, the capability set may be used to indicate an adjustment range of each parameter. For example, the capability set may be { sensitivity (a, b), contrast (c, d), sharpness (e, f), saturation (g, h), … … }.

After the camera device obtains the capability set, a fifth feedback result may be generated, where the fifth feedback result carries the capability set, and the fifth feedback result is used to transmit the capability set of the camera device to the terminal.

4084. The designated function is an equipment alarm function:

when the appointed function is the equipment alarm function, the appointed instruction identification is the instruction identification corresponding to the equipment alarm function interface, and the camera equipment can operate the equipment alarm function interface to alarm.

After the alarm of the camera device is finished, if the alarm is successful, a sixth feedback result can be generated, wherein the operation state in the sixth feedback result is a success state, and the sixth feedback result is used for notifying the terminal that the camera device has successfully alarmed. If the alarm fails, a seventh feedback result may be generated, where an operation state in the seventh feedback result is a failure state, and the seventh feedback result is used to notify the terminal that the camera device failed to alarm.

409. And when the video equipment receives the feedback result, returning the feedback result to the terminal.

410. The terminal receives the feedback result.

When the video equipment receives the feedback result, the feedback result can be directly forwarded to the terminal without being processed, and after the terminal receives the feedback result, the feedback result can be analyzed to obtain the operation state of the camera equipment for executing the specified operation based on the specified function or obtain the parameter information of the camera equipment.

The first point to be noted is that the above process of returning the feedback result is only an optional step, and in practical applications, when the terminal does not need to know the operation state or parameter information of the video recording apparatus, the image capturing apparatus may only execute the specified operation based on the specified function, and does not generate and return the feedback result.

The second point to be noted is that various operations executed by the terminal may be encapsulated in an installation package of a specified client, and the terminal may install the specified client, and execute the operations executed by the terminal in the above embodiment in the process of running the specified client.

When the pressure sensor 1313 is disposed at a lower layer of the touch display screen 1305, the processor 1301 controls an operability control on the UI interface according to a pressure operation of the user on the touch display screen 1305. The operability control comprises at least one of a button control, a scroll bar control, an icon control and a menu control.

The fingerprint sensor 1314 is used for collecting the fingerprint of the user, and the identity of the user is identified by the processor 1401 according to the fingerprint collected by the fingerprint sensor 1314, or the identity of the user is identified by the fingerprint sensor 1314 according to the collected fingerprint. Upon recognizing that the user's identity is a trusted identity, processor 1401 authorizes the user to perform relevant sensitive operations including unlocking the screen, viewing encrypted information, downloading software, paying for, and changing settings, etc. The fingerprint sensor 1314 may be disposed on the front, back, or side of the terminal 1400. When a physical button or vendor Logo is provided on the terminal 1400, the fingerprint sensor 1314 may be integrated with the physical button or vendor Logo.

The optical sensor 1315 is used to collect the ambient light intensity. In one embodiment, the processor 1301 can control the display brightness of the touch display screen 1305 according to the intensity of the ambient light collected by the optical sensor 1315. Specifically, when the ambient light intensity is high, the display brightness of the touch display screen 1305 is increased; when the ambient light intensity is low, the display brightness of the touch display 1305 is turned down. In another embodiment, the processor 1301 can also dynamically adjust the shooting parameters of the camera assembly 1306 according to the ambient light intensity collected by the optical sensor 1315.

Proximity sensor 1316, also known as a distance sensor, is typically disposed on a front panel of terminal 1300. Proximity sensor 1316 is used to gather the distance between the user and the front face of terminal 1300. In one embodiment, the processor 1301 controls the touch display 1305 to switch from the bright screen state to the dark screen state when the proximity sensor 1316 detects that the distance between the user and the front face of the terminal 1300 gradually decreases; the touch display 1305 is controlled by the processor 1301 to switch from the rest state to the bright state when the proximity sensor 1316 detects that the distance between the user and the front face of the terminal 1300 gradually becomes larger.
