Technical Field

The embodiment of the invention relates to the technical field of computers, in particular to a mobile terminal, a method and a device for adjusting the brightness of a display screen of the mobile terminal, and a storage medium.

Background

The mobile terminal, especially the vehicle-mounted mobile terminal such as a vehicle-mounted recorder and the like outputs image information for a user to refer to in the moving process. Taking the vehicle-mounted mobile terminal as an example, the brightness in the vehicle changes with the change of the environment during the driving process of the vehicle, and if the brightness of the display screen of the vehicle-mounted mobile terminal is fixed, the watching of the user is affected. For example, in daytime, the light in the vehicle is bright, and if the brightness of the display screen is dark, the user cannot clearly see the displayed image; at night, light in the vehicle is darker, and if the brightness of the display screen is too bright, the rear-view effect is affected.

In a traditional display screen brightness adjusting mode, ambient light information is acquired through a photosensitive element built in a mobile terminal, and the display screen brightness is adaptively adjusted according to the ambient light information.

However, due to factors such as cost and terminal structure, if the mobile terminal is not equipped with a photosensitive element, the brightness of the display screen cannot be adjusted by using a conventional method.

In view of the problem that the brightness of a display screen cannot be adjusted without a photosensitive element in the prior art, the invention provides a mobile terminal, a method and a device for adjusting the brightness of the display screen of the mobile terminal, and a computer readable storage medium, which can adjust the brightness of the display screen without installing the photosensitive element.

In a first aspect, an embodiment of the present invention provides a method for adjusting brightness of a display screen, where the method includes:

acquiring the geographical position information of the mobile terminal;

acquiring the environment brightness information of the area where the mobile terminal is located according to the geographical position information;

and after the display screen brightness of the mobile terminal is determined to be not matched with the environment brightness information, adjusting the display screen brightness of the mobile terminal to be matched with the environment brightness information.

Because the environment brightness is related to the geographical position, the method provided by the embodiment of the invention acquires the geographical position information of the mobile terminal, thereby acquiring the environment brightness information of the area where the mobile terminal is located, and further adjusting the brightness of the display screen of the mobile terminal, so that the brightness of the display screen is matched with the environment brightness. The method provided by the embodiment of the invention can realize the adjustment of the brightness of the display screen without depending on a photosensitive element, thereby avoiding the situation that a user cannot clearly see the image output by the display screen due to the mismatching of the brightness of the display screen and the ambient brightness as much as possible and improving the safety and the reliability of the use of the mobile terminal.

With reference to the first aspect, in a first implementation manner of the first aspect of the embodiment of the present invention, the obtaining the ambient brightness information of the area where the mobile terminal is located according to the geographic location information includes:

determining current sunshine position information and/or current weather information of the area where the mobile terminal is located according to the geographical position information;

and acquiring first ambient brightness information corresponding to the current sunshine position information and/or the current weather information.

In the embodiment of the present invention, the specific factor affecting the ambient brightness may be a sunshine position and/or a weather condition in an area where the mobile terminal is located, for example, the ambient brightness is greatly reduced after the sun falls, and for example, the ambient brightness is greatly reduced in rainy days. Therefore, the current sunshine position information and/or the current weather information of the area where the mobile terminal is located can be determined according to the geographical position information, and then the corresponding first environment brightness information can be determined. Because the sunshine position information and the meteorological information resources are rich, and the information sources are accurately determined to be higher, the reliability of sequentially determined environment brightness is ensured to be higher, and the reliability of brightness adjustment of the display screen is further improved. In addition, the sunshine position and the weather change slowly and do not need to be updated frequently, so that the processing resources are saved.

With reference to the first implementation manner of the first aspect, in the first implementation manner of the first aspect of the present invention, the obtaining the geographic location information of the mobile terminal includes:

and acquiring first geographical position information of the mobile terminal after detecting a starting signal of a vehicle bearing the mobile terminal.

All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.

The method provided by the embodiment of the present invention may be executed on a mobile terminal, as shown in fig. 1, for convenience of description, only the part related to the embodiment of the present invention is shown, and specific technical details that are not disclosed are referred to as the method part of the embodiment of the present invention. The mobile terminal can be any terminal equipment including a vehicle data recorder, an intelligent rearview mirror, a vehicle-mounted computer, a mobile phone and the like.

The method for adjusting the brightness of the display screen implemented by the mobile terminal is described in detail below with reference to the accompanying drawings.

In a first aspect, an embodiment of the present invention provides a method for adjusting brightness of a display screen of a mobile terminal, as shown in fig. 2, the method includes the following steps:

step 201, obtaining the geographical location information of the mobile terminal.

In the embodiment of the present invention, there are various ways to obtain the geographic location information of the mobile terminal, for example, the geographic location information is obtained from a satellite Positioning signal such as a GPS (Global Positioning System) or a beidou signal, and the geographic location information may also be obtained by using a Positioning technology such as inertial navigation.

The geographic location information may be, but is not limited to, latitude and longitude information.

Step 202, obtaining the environment brightness information of the area where the mobile terminal is located according to the geographical position information.

Specifically, the area where the mobile terminal is located can be obtained according to the geographical location information, and then the ambient brightness information of the area can be obtained.

In the embodiment of the present invention, the area of the mobile terminal may be divided into a plurality of areas, for example, a time zone in which the mobile terminal is located, a country in which the mobile terminal is located, a province/city in which the mobile terminal is located, a cell in which the mobile terminal is located, and the like.

Step 203, after determining that the display screen brightness of the mobile terminal is not matched with the environment brightness information, adjusting the display screen brightness of the mobile terminal to be matched with the environment brightness information.

The matching relation between the brightness of the display screen and the ambient brightness can be established in advance, and judgment and adjustment are carried out according to the matching relation.

The matching relationship may be in a table form, a formula form, a function curve form, and the like, which is not limited in the embodiment of the present invention.

Because the environment brightness is related to the geographical position, the method provided by the embodiment of the invention acquires the geographical position information of the mobile terminal, thereby acquiring the environment brightness information of the area where the mobile terminal is located, and further adjusting the brightness of the display screen of the mobile terminal, so that the brightness of the display screen is matched with the environment brightness. The method provided by the embodiment of the invention can realize the adjustment of the brightness of the display screen without depending on a photosensitive element, thereby avoiding the situation that a user cannot clearly see the image output by the display screen due to the mismatching of the brightness of the display screen and the ambient brightness as much as possible, and improving the safety and the reliability of the use of the mobile terminal.

In the embodiment of the invention, on the basis of the geographical position information, various factors influencing the environment brightness can be provided, such as special environments such as sunshine positions, meteorological conditions, underground parking lots and the like. The method provided by the embodiment of the invention is explained in detail below based on each influencing factor or the combination of the influencing factors.

In one implementation, the specific implementation manner of the step 202 may be: determining current sunshine position information and/or current weather information of the area where the mobile terminal is located according to the geographical position information; and acquiring first environment brightness information corresponding to the current sunshine position information and/or the current weather information.

In practical application, the system can be configured to determine only the current sunshine position information, can also be configured to determine only the current weather information, and can also be configured to determine both the sunshine position information and the weather information.

The corresponding relation between the sunshine positions and the time of different areas can be preserved in advance, the corresponding relation between the sunshine positions and the time of the area where the geographical position information is located is found according to the geographical position information, and the sunshine position information corresponding to the current time is searched in the corresponding relation; the geographical position information can also be sent to a network server, and the sunshine position information returned by the network server is received.

The geographical location information may be sent to a network server, which returns current weather information for the area in which the geographical location information is located to the mobile terminal.

The corresponding relation between the sunshine position information and/or the weather information and the environment brightness can be preserved in advance, and the environment brightness information corresponding to the current sunshine position information and/or the current weather information is obtained by searching the corresponding relation. In the embodiment of the present invention, the ambient brightness information corresponding to the sunshine position information and/or the weather information is referred to as first ambient brightness information.

If the ambient brightness information is not continuously determined based on other factors, the step 203 is directly performed according to the first ambient brightness information.

It should be noted that, in a specific application, the sunshine position information and the weather information can also be regarded as the environment brightness information, that is, the matching relationship between the sunshine position information and/or the weather information and the brightness of the display screen is established in advance, and then the above step 203 is executed.

In the embodiment of the present invention, the specific factor affecting the ambient brightness may be a sunshine position and/or a weather condition in an area where the mobile terminal is located, for example, the ambient brightness is greatly reduced after the sun falls, and for example, the ambient brightness is greatly reduced in rainy days. Therefore, the current sunshine position information and/or the current weather information of the area where the mobile terminal is located can be determined according to the geographical position information, and further the corresponding first environment brightness information can be determined. Because the sunshine position information and the meteorological information resources are rich, and the information sources are accurately determined to be higher, the reliability of the sequentially determined environment brightness is higher, and the reliability of the brightness adjustment of the display screen is further improved. In addition, the sunshine position and the weather change slowly and do not need to be updated frequently, so that the processing resources are saved.

As described above, since the sunshine position and the weather condition change slowly, it is not necessary to frequently acquire the geographical location information, and preferably, the geographical location information may be acquired after the vehicle bearing the mobile terminal is detected to be started, and the sunshine position information and/or the weather information may be subsequently determined according to the geographical location information acquired this time, thereby avoiding frequent occupation of communication and calculation resources. In this embodiment of the present invention, the implementation manner of obtaining the geographic location information of the mobile terminal may be: and after detecting a starting signal of a vehicle bearing the mobile terminal, acquiring the geographical position information of the mobile terminal.

In the embodiment of the invention, the geographical position information acquired after the starting signal is detected is called as the first geographical position information,

in the embodiment of the present invention, the vehicle may be, but is not limited to, a motor vehicle, a bicycle, a boat, etc.

The embodiment of the invention does not limit the specific implementation mode of detecting the starting signal. For example, an ACC (adaptive cruise control) signal of the vehicle is detected, and the detected ACC signal is used as the activation signal. For another example, the moving speed or acceleration of the mobile terminal is determined from an attitude sensor (e.g., an accelerometer, a gyroscope, etc.) of the mobile terminal, and the moving speed or acceleration is used as the activation signal when the moving speed or acceleration is detected and the vehicle of the mobile terminal is considered to be activated.

Even if the sunshine position and the weather condition change slowly, if the mobile terminal moves for a long time, the current sunshine position and the weather condition of the area where the mobile terminal is located may change, and in order to ensure the accuracy of the detection of the ambient brightness, the current sunshine position information and/or the current weather information can be determined according to a preset time interval. That is, the current sunshine position information and/or the current weather information of the area where the mobile terminal is located are determined according to the first geographical position information at a predetermined time interval.

Besides the above-mentioned manner of obtaining the geographical location information, the geographical location information may also be obtained at predetermined time intervals, and the sunshine location information and/or weather information may be obtained after the geographical location information is obtained each time.

If the first geographical location information is only used for acquiring the sunshine location information and/or the weather information, preferably, the time interval for acquiring the first geographical location information is the same as the time interval for acquiring the sunshine location information and/or the weather information.

On the basis of the implementation mode, whether an abnormal brightness area exists or not can be judged to determine the ambient brightness, and correspondingly, second geographical position information of the mobile terminal is obtained according to a preset time interval; step 202 may further include: determining whether the mobile terminal is located in a predetermined abnormal brightness area according to each piece of the second geographical location information, or determining whether a predetermined abnormal brightness area exists on a navigation path within a predetermined distance or time according to each piece of the second geographical location information; after determining that an abnormal brightness area exists, acquiring second ambient brightness information corresponding to the abnormal brightness area; and determining the environment brightness information of the area where the mobile terminal is located according to the first environment brightness information and/or the second environment brightness information.

In the embodiment of the present invention, the ambient brightness information determined based on the abnormal brightness region is referred to as second brightness information.

The abnormal brightness area refers to an area with an ambient brightness different from the normal outdoor ambient brightness of the local area, such as an underground parking lot, a tunnel, and the like.

In the embodiment of the invention, whether the mobile terminal is in the abnormal environment brightness area at present can be determined according to the real-time geographical position information of the mobile terminal. Specifically, the geographical position information is input into the electronic map, and whether the electronic map is in the abnormal environment brightness area or not is determined according to the electronic map.

If the mobile terminal is fast in moving speed, the brightness of the display screen is adjusted after the mobile terminal enters the abnormal environment brightness area, and the display effect can be influenced, so that whether the mobile terminal enters the abnormal environment brightness area or not can be judged in advance by utilizing the characteristics of a navigation planning path; in this case, the environmental brightness information of the area where the mobile terminal is located in step 202 specifically refers to the environmental brightness information of the area where the mobile terminal is located. Accordingly, in step 203, the brightness of the display screen may be adjusted after the abnormal ambient brightness area is actually entered, or may be adjusted in advance.

The following specifically describes the implementation manner by taking brightness adjustment of a display screen of the vehicle-mounted automobile data recorder as an example.

In one embodiment, after the vehicle-mounted automobile data recorder is started, an ACC signal of an automobile is detected, longitude and latitude information is acquired through a GPS signal after the ACC signal of the automobile is detected, current sunlight position information and current weather information of a region where the vehicle-mounted automobile data recorder is located are acquired according to the longitude and latitude information, environment brightness information is determined according to the two information, whether brightness adjustment of a display screen is needed or not is judged, and after the fact that the brightness adjustment is needed is judged, the brightness of the display screen is adjusted to be matched with the environment brightness information; and then, acquiring longitude and latitude information through a GPS signal according to a preset time interval, determining whether a preset abnormal brightness area exists on a navigation path within a preset distance or time according to the longitude and latitude information, acquiring environment brightness information corresponding to the abnormal environment brightness area if the abnormal environment brightness area exists within each time interval, further judging whether the brightness of the display screen needs to be adjusted, and adjusting the brightness of the display screen to be matched with the environment brightness information after judging that the brightness needs to be adjusted.

In another embodiment, after the vehicle-mounted automobile data recorder is started, an ACC signal of an automobile is detected, after the ACC signal of the automobile is detected, longitude and latitude information is acquired through a GPS signal, current sunshine position information and current weather information of a region where the vehicle-mounted automobile data recorder is located are acquired according to the longitude and latitude information, environment brightness information is determined according to the two pieces of information, whether display screen brightness adjustment is needed or not is judged, and after the judgment that the adjustment is needed, the display screen brightness is adjusted to be matched with the environment brightness information; then, according to a preset time interval, acquiring longitude and latitude information through a GPS signal, determining whether a preset abnormal brightness area exists on a navigation path within a preset distance or time according to the longitude and latitude information, if the abnormal environment brightness area exists within each time interval, acquiring environment brightness information corresponding to the abnormal environment brightness area, weighting the environment brightness information (second environment brightness information) and the environment brightness information (first environment information) acquired based on the sunshine position information and the weather information, acquiring environment brightness information, judging whether display screen brightness adjustment is needed according to the environment brightness information, and adjusting the display screen brightness to be matched with the environment brightness information after judging that the display screen brightness adjustment is needed.

Wherein the weight of the second ambient brightness information is greater than the weight of the first ambient brightness information.

In another implementation mode, the sunshine position information and/or the weather information do not need to be combined, the environment brightness is determined only based on the abnormal environment brightness area, and specifically, the second geographical position information of the mobile terminal is obtained according to a preset time interval; respectively determining whether the mobile terminal is located in a preset abnormal brightness area according to each piece of second geographical location information, or respectively determining whether a preset abnormal brightness area exists on a navigation path within a preset distance or time according to each piece of second geographical location information; and after determining that the abnormal brightness area exists, acquiring second ambient brightness information corresponding to the abnormal brightness area.

In the embodiment of the invention, on the basis of the geographical position information, various factors influencing the environment brightness can be provided, such as special environments such as sunshine positions, meteorological conditions, underground parking lots and the like. The method provided by the embodiment of the present invention is described in detail below based on each influencing factor or a combination of influencing factors.

In one implementation, the ambient brightness information includes first ambient brightness information, and the ambient brightness determination module is configured to:

determining the current sunshine position information and/or the current weather information of the area where the mobile terminal is located according to the geographical position information;

The corresponding relation between the sunshine positions and the time of different areas can be preserved in advance, the corresponding relation between the sunshine positions and the time of the area where the geographical position information is located is found according to the geographical position information, and the sunshine position information corresponding to the current time is searched in the corresponding relation; or sending the geographical position information to a network server and receiving sunshine position information returned by the network server.

The geographical location information may be sent to a network server, which returns the current weather information of the area in which the geographical location information is located to the mobile terminal.

The corresponding relation between the sunshine position information and/or the weather information and the environment brightness can be preserved in advance, and the environment brightness information corresponding to the current sunshine position information and/or the current weather information can be obtained by searching the corresponding relation. In the embodiment of the present invention, the ambient brightness information corresponding to the sunshine position information and/or the weather information is referred to as first ambient brightness information.

And if the environment brightness information is not judged based on other factors subsequently, matching and adjusting are directly carried out according to the first environment brightness information.

It should be noted that, in a specific application, the sunshine position information and the weather information may also be regarded as the environment brightness information, that is, a matching relationship between the sunshine position information and/or the weather information and the brightness of the display screen is established in advance, and then matching and adjustment are performed.

In the embodiment of the present invention, the specific factor affecting the ambient brightness may be a sunshine position and/or a weather condition in an area where the mobile terminal is located, for example, the ambient brightness is greatly reduced after the sun falls, and for example, the ambient brightness is greatly reduced in rainy days. Therefore, the current sunshine position information and/or the current weather information of the area where the mobile terminal is located can be determined according to the geographical position information, and then the corresponding first environment brightness information can be determined. Because the sunshine position information and the meteorological information resources are rich, and the information sources are accurately determined to be higher, the reliability of the sequentially determined environment brightness is higher, and the reliability of the brightness adjustment of the display screen is further improved. In addition, the sunshine position and the weather change slowly, and frequent updating is not needed, so that the processing resource is saved.

As described above, since the sunshine position and the weather condition change slowly, it is not necessary to frequently acquire the geographical location information, and preferably, the geographical location information may be acquired after the vehicle bearing the mobile terminal is detected to be started, and the sunshine position information and/or the weather information may be subsequently determined according to the geographical location information acquired this time, thereby avoiding frequent occupation of communication and calculation resources. Correspondingly, the geographic location information includes first geographic location information, and the geographic location determining module is configured to:

On this basis, in order to determine the current sunshine position information and/or the current weather information of the area where the mobile terminal is located according to the geographical position information, the environment brightness determination module is configured to:

In the embodiment of the present invention, the vehicle may be, but is not limited to, a motor vehicle, a bicycle, a boat, and the like.

The embodiment of the invention does not limit the specific implementation mode of detecting the starting signal. For example, an ACC (adaptive cruise control) signal of the vehicle is detected, and the detected ACC signal is used as the start signal. For another example, the moving speed or acceleration of the mobile terminal is determined from an attitude sensor (e.g., an accelerometer, a gyroscope, etc.) of the mobile terminal, and the moving speed or acceleration is used as an activation signal when the moving speed or acceleration is detected and the vehicle of the mobile terminal is considered to be activated.

Even if the sunshine position and the weather condition change slowly, if the mobile terminal moves for a long time, the current sunshine position and the weather condition of the area where the mobile terminal is located may change, and in order to ensure the accuracy of the detection of the ambient brightness, the current sunshine position information and/or the current weather information can be determined according to a preset time interval. That is, the current sunshine position information and/or the current weather information of the area where the mobile terminal is located are determined according to the first geographical position information at predetermined time intervals.

On the basis of the foregoing implementation manner, it may further be determined whether an abnormal luminance area exists to determine the ambient luminance, and correspondingly, the geographic location information includes second geographic location information, and the geographic location determining module is configured to: acquiring second geographical position information of the mobile terminal according to a preset time interval;

In addition to the effect of the current sunshine position, weather conditions, etc. of the area where the mobile terminal is located on the ambient brightness, the ambient brightness is also affected by the specific location area where the mobile terminal is located. For example, when the mobile terminal enters an abnormal brightness area such as an underground parking lot and a tunnel, the ambient brightness changes greatly, so that whether the mobile terminal is located in the abnormal brightness area or is about to enter the abnormal brightness area is judged, the ambient brightness information can be determined more accurately, and the reliability of adjustment is improved.

In the embodiment of the invention, whether the mobile terminal is currently in the abnormal environment brightness area can be determined according to the real-time geographical position information of the mobile terminal. Specifically, the geographical position information is input into the electronic map, and whether the electronic map is in the abnormal environment brightness area or not is determined according to the electronic map.

If the mobile terminal is fast in moving speed, the brightness of the display screen is adjusted after the mobile terminal enters the abnormal environment brightness area, and the display effect can be influenced, so that whether the mobile terminal enters the abnormal environment brightness area or not can be judged in advance by utilizing the characteristics of a navigation planning path; in this case, the ambient brightness information of the area where the mobile terminal is located is specifically ambient brightness information of the area where the mobile terminal is located. Correspondingly, the brightness of the display screen can be adjusted after the display screen actually enters the abnormal environment brightness area, and the display screen can also be adjusted in advance.

In an embodiment of the present invention, in order to determine the ambient brightness information of the area where the mobile terminal is located according to the first ambient brightness information and/or the second ambient brightness information, the ambient brightness determining module is configured to:

In another implementation manner, the sunshine position information and/or the weather information do not need to be combined, and only the ambient brightness needs to be determined based on an abnormal ambient brightness area, specifically, the geographic position information includes second geographic position information, and the geographic position determining module is configured to: acquiring second geographical position information of the mobile terminal according to a preset time interval;

the processor is configured to execute the program stored in the memory.

The audio circuit 160 may transmit the electrical signal converted from the received audio data to the speaker 161, and convert the electrical signal into a sound signal for output by the speaker 161; on the other hand, the microphone 162 converts the collected sound signal into an electrical signal, which is received by the audio circuit 160 and converted into audio data, and then the audio data is processed by the audio data output processor 180, and then the processed audio data is sent to another mobile phone through the WiFi module 170, or the audio data is output to the memory 120 for further processing.

WiFi belongs to short distance wireless transmission technology, and rear-view mirror vehicle event data recorder can help the user to receive and dispatch the email, browse the webpage and visit streaming media etc. through WiFi module 170, and it provides wireless broadband internet access for the user.

The processor 180 is a control center of the rear view mirror driving recorder, connects various parts of the whole rear view mirror driving recorder by using various interfaces and lines, and performs various functions and processes data of the rear view mirror driving recorder by running or executing an application program and/or a module stored in the memory 120 and calling data stored in the memory 120, thereby performing overall monitoring of the rear view mirror driving recorder. Alternatively, processor 180 may include one or more processing units; preferably, the processor 180 may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into the processor 180.
