In the exemplary embodiments described below, a terminal is sometimes also referred to as an intelligent terminal device, where the terminal may be a Mobile terminal, and may also be referred to as a User Equipment (UE), a Mobile Station (MS), and the like. A terminal is a device that provides voice and/or data connection to a user, or a chip disposed in the device, such as a handheld device, a vehicle-mounted device, etc. having a wireless connection function. Examples of terminals may include, for example: the Mobile terminal comprises a Mobile phone, a tablet computer, a notebook computer, a palm computer, Mobile Internet Devices (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in remote operation, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home and the like.

In a dark environment, the user manually searches for the application with the illumination function in the terminal and then manually opens the application with the illumination function, so that on one hand, time is consumed, and on the other hand, if the user cannot find and open the application with the illumination function in time, safety risks exist.

The embodiment of the disclosure provides an illumination compensation method. According to the illumination compensation method, the light intensity of the current environment of the terminal is obtained, the state parameter of the terminal is obtained when the light intensity is determined to be smaller than the preset light intensity threshold value, and if the current scene of the terminal is determined to accord with the preset scene based on the state parameter, the light compensation can be automatically carried out on the terminal, so that the illumination requirement of a user in a dark environment is facilitated. The light intensity of the environment where the terminal is located is judged to be expected in sequence, and the terminal is judged to be located based on the state parameters of the terminal, after the scene where the terminal is located is judged to be in accordance with the preset scene, the terminal automatically carries out light compensation, the user does not need to manually search and open the application with the illumination function, the time of operating the terminal by the user is saved, and the use experience of the user on the terminal is improved.

Fig. 1 is a flowchart illustrating an illumination compensation method according to an exemplary embodiment, where the illumination compensation method is used in a terminal, as shown in fig. 1, and includes the following steps.

In step S11, the light intensity of the current environment of the terminal is obtained, and when it is determined that the light intensity is less than the preset light intensity threshold, the state parameter of the terminal is obtained.

According to the method and the device, the light intensity of the current environment of the terminal can be acquired through the light sensor installed in the terminal, the acquired light intensity of the current environment of the terminal is compared with the preset light intensity threshold value, and when the light intensity of the current environment of the terminal is determined to be smaller than the preset light intensity threshold value, the current light intensity of the terminal can be determined to meet the expectation. And further acquiring the state parameters of the terminal according to the condition that the light intensity of the current environment of the terminal is smaller than a preset light intensity threshold value.

Among them, the light sensors installed in the terminal may include a front light sensor and a rear light sensor. The light intensity of the current environment of the terminal is obtained, which may be a first light intensity of the current environment of the terminal collected by a front light sensor and a second light intensity of the current environment of the terminal collected by a rear light sensor. For convenience of description, the light intensity of the current environment of the terminal, collected by the front light sensor, is referred to as a first light intensity, and the light intensity of the current environment of the terminal, collected by the rear light sensor, is referred to as a second light intensity.

Determining that the light intensity is less than the preset light intensity threshold may be determined, for example, by:

and comparing the first light intensity and the second light intensity with the light intensity threshold respectively, and determining that the current ambient light intensity is smaller than a preset light intensity threshold when the first light intensity and the second light intensity are both smaller than the light intensity threshold.

And after the first light intensity and the second light intensity are both smaller than the light intensity threshold, state parameters representing the current state of the terminal can be obtained. The state parameters may include, for example, the state of motion of the terminal and the angle of inclination of the terminal relative to the ground. The motion state of the terminal and the inclination angle of the terminal relative to the ground may be based on an Inertial Measurement Unit (IMU) including an acceleration sensor and a gyroscope, and based on the IMU, after acquiring the attitude data of the terminal in the three-dimensional coordinate plane, it may be known whether the terminal is in the motion state, and the inclination angle of the terminal relative to the ground may be obtained by preprocessing the attitude data of the terminal in the three-dimensional coordinate plane.

For example, the terminal may have one side of the terminal screen as an X-axis and the other side of the terminal screen as a Y-axis in a three-dimensional coordinate plane, and a direction perpendicular to the terminal screen as a Z-axis in the three-dimensional coordinate plane. After the IMU acquires the current attitude data of the terminal on the three-dimensional coordinate plane, the terminal is determined to be in a motion state at present, and the inclination angle of the current terminal and the ground can be obtained to be 40 degrees according to the fixed relation between the accelerometer sensor coordinate system and the terminal position coordinate system.

In step S12, if it is determined that the current scene of the terminal matches the preset scene based on the state parameters, light compensation is performed on the terminal.

In this disclosure, the preset scene may be a dark environment in which the current environment representing the terminal is weak in light and needs to be illuminated in the dark environment. In a real-time mode, the preset scene may be a dark environment where the light intensity of the current environment of the terminal is lower than a preset light intensity threshold value and the characteristic light is weak, the terminal is in motion, and the inclination angle of the terminal relative to the ground is greater than or equal to 20 degrees and less than or equal to 90 degrees.

In a real-time mode, for example, the light intensity of the current environment of the terminal is obtained through a light sensor installed in the terminal, the obtained light intensity of the current environment of the terminal is compared with a preset light intensity threshold value, the light intensity of the current environment of the terminal is determined to be in accordance with a dark environment, the terminal obtained through an IMU is in motion, the inclination angle of the terminal relative to the ground is 40 degrees, and then a scene in which the terminal is currently located is determined to be in accordance with a preset scene based on a state parameter that the inclination angle of the terminal relative to the ground is 40 degrees.

In order to improve the user experience of the terminal, in one embodiment, when it is determined that the current scene of the terminal conforms to the preset scene, the terminal may be automatically subjected to light compensation based on the state parameters of the terminal.

In an exemplary embodiment of the disclosure, the light intensity of the current environment of the terminal is obtained, the state parameter of the terminal is obtained when the light intensity is determined to be smaller than a preset light intensity threshold, and if it is determined that the current scene of the terminal meets a preset scene based on the state parameter, light compensation can be automatically performed on the terminal, so that the illumination requirement of a user in a dark environment is facilitated. The light intensity of the environment where the terminal is located is judged to be expected in sequence, and the terminal is judged to be located based on the state parameters of the terminal, after the scene where the terminal is located is judged to be in accordance with the preset scene, the terminal automatically carries out light compensation, the user does not need to manually search and open the application with the illumination function, the time of operating the terminal by the user is saved, and the use experience of the user on the terminal is improved.

In step S21, the light intensity of the current environment of the terminal is obtained, and when it is determined that the light intensity is smaller than the preset light intensity threshold, a status parameter of the terminal is obtained, where the status parameter includes an air pressure value variation of the terminal.

In order to prevent an error in the acquired terminal state parameters based on the IMU and ensure that the state of the terminal is accurate, in the disclosure, after a first light intensity of the current environment of the terminal acquired by a front light sensor and a second light intensity acquired by a rear light sensor are acquired, and both the first light intensity and the second light intensity are smaller than a light intensity threshold, an inclination angle of the terminal relative to the ground determined based on the IMU is acquired, and when it is determined that the current scene of the terminal conforms to a preset scene based on the inclination angle of the terminal relative to the ground determined based on the IMU, a state parameter of another terminal, that is, an air pressure value variation of the terminal, can be acquired based on an air pressure gauge installed in the terminal.

For example, the air pressure value change amount may be obtained by obtaining a current air pressure value displayed by the barometer and determining an air pressure change amount between the current air pressure value and an air pressure value displayed last time.

In step S22, if it is determined that the current scene of the terminal matches the preset scene based on the state parameters, light compensation is performed on the terminal.

In one embodiment, if the terminal is in motion, the current inclination angle of the terminal relative to the ground is within a preset angle range, and if the air pressure variation is greater than or equal to a preset air pressure threshold, it is determined that the current scene where the terminal is located conforms to the state parameters of the preset scene. And then through the terminal motion state based on IMU confirms, the inclination of terminal relative ground to and the atmospheric pressure value variable quantity of confirming through the barometer, can ensure that the state parameter of terminal is accurate, based on accurate state parameter, can accurately confirm whether the scene that the terminal is currently located accords with the preset scene, and then the scene that the terminal is currently located can carry out light compensation to the terminal when according with the preset scene.

For example, the preset scene is a scene of going upstairs or downstairs, if the terminal is in motion, the current inclination angle of the terminal relative to the ground is 40 degrees, and the air pressure variation is greater than or equal to the preset air pressure threshold value, it is determined that the terminal is currently in dark ambient light, and in the scene of going upstairs or downstairs, illumination compensation can be automatically performed on the terminal based on that the terminal is currently in dark ambient light, and in the scene of going upstairs or downstairs, the illumination requirement of a user in a dark environment is facilitated, and the use experience of the user on the terminal is improved.

In the exemplary embodiment of the disclosure, when it is determined that the light intensity is smaller than the preset light intensity threshold, the state parameter determined based on the IMU is acquired, and the state parameter including the air pressure value variation of the terminal is acquired, so that the state of the terminal can be ensured to be accurate, and further, based on the accurate state of the terminal, when the current scene of the terminal meets the preset scene, the light compensation can be timely and automatically performed on the terminal, so that the illumination requirement of a user in a dark environment is facilitated. By automatically performing light compensation on the terminal, the user does not need to manually search and open the application with the illumination function, so that the time for operating the terminal by the user can be saved, and the use experience of the user on the terminal is improved.

Fig. 3 is a flowchart illustrating an illumination compensation method according to an exemplary embodiment, where the illumination compensation method is used in a terminal, as shown in fig. 3, and includes the following steps.

In step S31, the light intensity of the current environment of the terminal is obtained, and when it is determined that the light intensity is less than the preset light intensity threshold, the state parameter of the terminal is obtained.

In step S32, if it is determined that the current scene of the terminal matches the preset scene based on the state parameters, the current state parameters of the terminal are reported to a designated application having an illumination function, and light compensation is performed on the terminal through the designated application.

A specific application with a lighting function in the present disclosure may be, for example, a flashlight of a terminal.

The following description of the illumination compensation method according to the present disclosure is made with reference to the state parameters of the terminal including the air pressure variation, the preset scene is a scene in which the ambient light intensity is lower than the preset light intensity threshold and the terminal is in an upward motion.

FIG. 4 is a flow chart illustrating a method of illumination compensation according to an exemplary embodiment. In fig. 4, when detecting the light sensing data of the terminal, the first light intensity L1 of the current environment of the terminal is mainly collected by the front light sensor installed in the terminal, the second light intensity L2 of the current environment of the terminal is collected by the rear light sensor installed in the terminal, the first light intensity L1 and the second light intensity L2 are compared with the light intensity threshold, and after determining that the first light intensity L1 and the second light intensity L2 are both smaller than the light intensity threshold, the terminal is determined to be in a dark environment. And then after the terminal is determined to be in a dark environment, the terminal is determined to be in motion based on the IMU, and after the terminal is determined to be in an inclination angle relative to the ground, the variation of the air pressure value of the terminal is obtained, wherein the variation of the air pressure is larger than a preset air pressure threshold value, so that the current scene where the terminal is located is determined to accord with the preset scene based on the state parameters. And then according to the fact that the current scene of the terminal accords with the preset scene, the illumination compensation device with the illumination function is automatically started to perform light compensation on the terminal, and the illumination requirements of a user in a dark environment are facilitated.

In fig. 5, in the process that a user carries a terminal to go upstairs, a first light intensity L1 of the current environment of the terminal is acquired by the front light sensor installed in the terminal, a second light intensity L2 of the current environment of the terminal is acquired by the rear light sensor installed in the terminal, and the first light intensity L1 and the second light intensity L2 are compared with a light intensity threshold to determine that both the first light intensity L1 and the second light intensity L2 are less than the light intensity threshold. Further, after the first light intensity L1 and the second light intensity L2 are determined to be smaller than the light intensity threshold, the terminal is in motion based on the IMU, the inclination angle of the terminal relative to the ground is, for example, 30 °, the terminal air pressure value variation is obtained, and the air pressure variation is larger than the preset air pressure threshold, so that after the current scene of the terminal is determined to accord with the preset scene based on the state parameters, the state of the current scene of the terminal, which accords with the preset scene, is reported to the flashlight of the terminal, and the flashlight of the terminal is automatically turned on based on the received reported information, so as to perform light compensation on the terminal. The front light sensor after the light compensation acquires a first light intensity L1 'of the current environment of the terminal, and the rear light sensor after the light compensation acquires a second light intensity L2' of the current environment of the terminal. Therefore, the user can conveniently meet the illumination requirement of the user in a dark environment based on the terminal after light compensation.
