In the embodiments of the present disclosure, a method for controlling a flashlight of a mobile terminal is provided first, which overcomes the defect of uneven light intensity distribution in the related art at least to a certain extent.

FIG. 1 shows a schematic flowchart of a method for controlling a flashlight of a mobile terminal according to an exemplary embodiment of the present disclosure. The execution subject of the method for controlling a flashlight of a mobile terminal may be a mobile terminal that controls the flashlight.

Referring to FIG. 1 , a method for controlling a flashlight of a mobile terminal according to an embodiment of the present disclosure includes the following steps:

Step S110, when it is detected that the first flashing light and the second flashing light are in an on state, identify the current application scene;

Step S120, according to the current application scenario, adjust the driving parameters of the first flash and the second flash to adjust the illuminance parameters of the first flash and the second flash.

In the technical solution provided by the embodiment shown in FIG. 1 , on the one hand, by setting a first flash and a second flash with different illumination parameters on the mobile terminal (specifically, the central illumination of the first flash is greater than the ambient illumination, the second The central illuminance of the flash is less than the surrounding illuminance), the light of the first flash and the second flash can be superimposed to improve the uniformity of the light intensity distribution, and solve the technical problem of partial overexposure in night photography due to uneven light intensity distribution in the related art , which improves the quality of night shots and the visual effects of photos. On the other hand, when it is detected that the first flash and the second flash are turned on, the current application scene is identified, and the driving parameters of the first flash and the second flash are adjusted according to the current application scene, so as to adjust the first flash and the second flash. The illumination parameters of the flash can present different lighting effects according to different scenes and different user needs, which improves the problem of single and dazzling light effects of the traditional flash, and optimizes the user experience.

The specific implementation process of each step in FIG. 1 is described in detail below:

A mobile terminal refers to a computer device that can be used on the move. For example, a mobile terminal in the present disclosure may include a mobile phone, a notebook, a tablet computer, etc., which can be set according to actual conditions, and belong to the protection scope of the present disclosure.

The above-mentioned mobile terminal is provided with at least a first flashlight and a second flashlight, and the lampshade structures of the first flashlight and the second flashlight are different, so that the illuminance parameters (including the central illuminance and the surrounding illuminance) of the first flashlight and the second flashlight are different. , the central illuminance of the first flash can be set to be greater than the surrounding illuminance, and the central illuminance of the second flash can be set to be lower than the surrounding illuminance.

Exemplarily, an anti-reflection film may also be provided on the lampshade structure of the first flash according to actual needs (for example, an anti-reflection film is provided in the central area of the lampshade of the first flash), and/or, on the lampshade structure of the first flash An anti-reflection film is provided (for example, an anti-reflection film is set around the lampshade of the first flash) to increase the transmitted light intensity in the central area and reduce the transmitted light intensity in the surrounding area, so that the central illuminance of the first flash is greater than the surrounding illuminance.

An anti-reflection film can also be arranged on the lampshade structure of the second flash (for example, an anti-reflection film is arranged in the central area of the lampshade of the second flash) to reduce the transmitted light intensity in the central area, so that the central illumination of the second flash is lower than that of the surrounding area. Illumination. In addition, on the basis of disposing the anti-reflection film in the central area of the lampshade of the second flash, an anti-reflection film may also be disposed around the lampshade of the second flash to reduce the intensity of the transmitted light in the central area and increase the intensity of the transmitted light in the surrounding areas , so that the central illuminance of the second flash is smaller than the surrounding illuminance.

Exemplarily, FIG. 2 shows a schematic diagram of a flash control method of a mobile terminal in an exemplary embodiment of the present disclosure, and specifically shows a schematic diagram of the positional relationship between the first flash and the second flash on the mobile terminal. Referring to FIG. 2 , 201 Shown is a mobile terminal, and 202 is a camera. The first flash 203 and the second flash 204 can be set around the camera 202 with a preset distance and a left-right positional relationship, or they can also be set with a preset distance and a top-bottom positional relationship. around the camera. It should be noted that the specific number and mutual positional relationship of the above-mentioned flashing lights can be set by themselves according to the actual situation, and belong to the protection scope of the present disclosure. The form of annular distribution is set around the camera to ensure that the subject can be evenly illuminated by light and improve the shooting quality.

Exemplarily, the central illuminance and the peripheral illuminance of the first flashlight and the second flashlight under different driving parameters may be measured in advance at different distances (the distance between the measurement position and the mobile terminal). Wherein, the driving parameter may be a driving current or a driving voltage, etc. In the following embodiments, the driving parameter is a driving current as an example for description.

Exemplarily, FIG. 3A shows a schematic diagram of a flash control method for a mobile terminal in an exemplary embodiment of the present disclosure, and specifically shows that when the driving current is 1A, the central illuminance and the Referring to FIG. 3A for a schematic diagram of the surrounding illuminance, it can be known that the central illuminance at this time is A ₁ , and the surrounding illuminance is B ₁ . For example, the measured central illuminance A ₁ of the first flash at this time is 100 lux, the surrounding illuminance B ₁ is 20 lux, and the ratio of the surrounding illuminance to the central illuminance is 1:5.

3B shows a schematic diagram of a flash control method of a mobile terminal in an exemplary embodiment of the present disclosure, and specifically shows a schematic diagram of the central illuminance and the surrounding illuminance measured at the above target distance and only the second flash is turned on when the driving current is 1A 3B , it can be known that the central illuminance at this time is A ₂ , and the surrounding illuminance is B ₂ . For example, the measured central illuminance A ₂ of the second flash at this time is 30 lux, the surrounding illuminance B ₂ is 60 lux, and the ratio of the surrounding illuminance to the central illuminance is 2:1.

3C shows a schematic diagram of a flash control method of a mobile terminal in an exemplary embodiment of the present disclosure, and specifically shows that when the driving current of the first flash is I ₁ and the driving current of the second flash is I ₂ , the above target distance measurement The schematic diagram of the central illuminance and the surrounding illuminance formed by the superposition of the first flash and the second flash, the central illuminance at this time is A ₁ *I ₁ +A ₂ *I ₂ , and the surrounding illuminance is B ₁ *I ₁ +B ₂ *I ₂ .

Therefore, when the driving current of the first flashing light is set to be 1A and the driving current of the second flashing light to 1A, the central illuminance formed by the natural superposition can be 100*1+30*1=130 lux, and the surrounding illuminance can be 20 *1+60*1=80lux, thus, a display effect in which the center is brighter than the surroundings can be visually presented.

When the driving current of the first flash is set to be 0.9A (the central illuminance of the first flash can be measured to be 90 lux, and the ambient illuminance can be 18 lux), and the driving current of the second flash is 1.45 A (the central illuminance of the second flash can be measured to be 18 lux) The illuminance can be 43.5lux, the surrounding illuminance can be 87lux), then the central illuminance formed by natural superposition can be 90*0.9+43.5*1.45=144.075lux, the surrounding illuminance is 18*0.9+87*1.45=142.35lux, the surrounding The ratio of the illuminance to the central illuminance is approximately 98.9%, so that the display effect in which the center and the surroundings are approximately as bright can be visually presented. Compared with the prior art, the uniformity of the light intensity distribution can be greatly improved, and the light intensity distribution can be solved A technical problem with poor photo quality caused by unevenness.

When the driving current of the first flash is set to be 0.3A (the central illuminance of the first flash can be measured to be 30 lux, and the ambient illuminance can be 6 lux), and the driving current of the second flash is 1.3 A (the central illuminance of the second flash can be measured to be 6 lux) The illuminance can be 39lux, and the surrounding illuminance can be 78lux), then the central illuminance formed by natural superposition can be 30*0.3+39*1.3=59.7lux, and the surrounding illuminance is 6*0.3+78*1.3=103.2lux, thus, It is possible to present a display effect that the periphery is brighter than the center.

After the relevant parameters corresponding to different lighting effects (the driving current of the first flash, the driving current of the second flash) are determined, the different lighting effects and the corresponding relevant parameters can be stored in advance, so as to facilitate the subsequent related processing process direct call. Exemplarily, reference can be made to Table 1, which shows an exemplary table in which the above-mentioned lighting effects and related parameters are stored correspondingly:

Table 1

It should be noted that different lighting effects may correspond to multiple sets of different related parameters, which may be set by themselves in combination with actual conditions, which is not specifically limited in the present disclosure.

Continuing to refer to FIG. 1 , in step S110 , when it is detected that the first flashing light and the second flashing light are in an on state, the current application scene is identified.

In this step, when it is detected that the first flash and the second flash are turned on, the current application scene can be identified. Exemplarily, the current application scene can include a shooting scene and a lighting scene. For details, please refer to FIG. 4 , FIG. 4 . A schematic diagram of a sub-process of identifying a current application scenario in an exemplary embodiment of the present disclosure is shown, including steps S401-S402. The specific implementation is explained below with reference to FIG. 4 .

In step S401, when it is detected that the first flash and the second flash are in an on state and the mobile terminal is in a shooting mode, it is determined that the current application scene is a shooting scene.

In this step, when the first flash and the second flash are turned on, if it is detected that the mobile terminal is in the shooting mode (for example, the current display interface of the mobile terminal is the shooting interface, the user performs a click operation on the shooting icon, etc., Then it is determined that the mobile terminal is in the shooting mode), and it can be determined that the current application scene is the shooting scene.

In step S402, when it is detected that the first flashlight and the second flashlight are in an on state and the mobile terminal is in a torch mode, it is determined that the current application scene is a lighting scene.

In this step, when the first flash and the second flash are turned on, if it is detected that the mobile terminal is in the shooting mode (for example: the current display interface of the mobile terminal is the shooting interface), it can be determined that the current application scene is lighting Scenes.

Continuing to refer to FIG. 1 , in step S120 , according to the current application scenario, the driving parameters of the first flash and the second flash are adjusted to adjust the illuminance parameters of the first flash and the second flash.

In this step, exemplarily, referring to the relevant explanations of the above steps and Table 1, if the current application scene is a shooting scene, the relevant parameters corresponding to "the center is as bright as the surroundings or roughly the same as the surroundings" can be automatically called, that is, the first The drive current of the flash is set to 0.9A, and the drive current of the second flash is set to 1.45A, so that the center can be as bright or roughly as bright as the surroundings, so that the light is evenly distributed to avoid local overexposure , to improve the shooting quality. If the current application scene is a lighting scene, the relevant parameters corresponding to "surroundings are brighter than the center" can be automatically called, that is, the driving current of the first flash is set to 0.3A, and the driving current of the second flash is set to 1.3A to show The surrounding lighting effect is brighter than the center, so that the lighting can be avoided to be too dazzling and the user experience can be optimized. It should be noted that the specific parameter calling settings can be set by themselves according to the actual situation, and belong to the protection scope of the present disclosure.

If the current application scene is a shooting scene, reference may also be made to FIG. 5 . FIG. 5 shows a schematic sub-flow diagram of a flash control method for a mobile terminal in an exemplary embodiment of the present disclosure, specifically illustrating adjusting the first flash and the first flash according to the brightness of the surrounding environment. A schematic diagram of a sub-flow for realizing different light intensity distributions by driving parameters of the two flash lamps, including steps S501-S502, the specific implementation is explained below with reference to FIG. 5 .

In step S501, the brightness of the surrounding environment is acquired.

In this step, the brightness of the surrounding environment can be obtained through the brightness sensor of the mobile terminal (a sensor that uses a photoelectric device as a conversion element, which can be used to detect non-electricity that directly causes changes in light brightness, and a sensor that uses a photoelectric element as a detection element), Brightness refers to the brightness of the picture, and the unit is candela per square meter (cd/m2) or nits, which is the number of candles per square meter. For example, the brightness of the surrounding environment obtained in this step may be L ₁ (candela/square meter).

Exemplarily, after acquiring the brightness of the surrounding environment, if it is determined that the brightness L1 of the surrounding environment is greater _than the brightness threshold L (preset brightness value), the first flash and/or the second flash may be controlled to be automatically turned off to Avoid in the case of high brightness, affecting the shooting effect.

In step S502, according to the corresponding relationship between the brightness, the preset brightness and the driving parameters of the first flash, the driving parameters of the first flash are adjusted; according to the corresponding relationship between the brightness, the preset brightness and the driving parameters of the second flash , adjust the driving parameters of the second flash.

In this step, the driving parameters of the first flash and the second flash may be adjusted according to the brightness of the surrounding environment. Specifically, the corresponding relationship between the preset brightness and the driving parameters of the first flash can be obtained (for example, the brightness is divided into a plurality of numerical intervals, and different numerical intervals correspond to different driving currents of the first flash. Specifically, the brightness can be set. The smaller the value, the greater the driving current of the first flash), and the corresponding relationship between the preset brightness and the driving current of the second flash (for example, the brightness is divided into multiple numerical intervals, and different numerical intervals correspond to the second flash). Specifically, the lower the brightness can be set, the greater the driving current of the second flash), and then, the driving parameters of the first flash are adjusted to the first target value, and the driving parameters of the second flash are adjusted to the third Two target values.

Exemplarily, the driving parameters of the first flash and the driving parameters of the second flash can also be adjusted according to the brightness, so that the central illuminance after the light of the two is superimposed is equal to or approximately equal to the surrounding illuminance (the light is evenly distributed), so as to avoid shooting scenes at night. The uneven distribution of light in the medium leads to a technical problem of local overexposure, improving the quality of the photo.

Therefore, the present disclosure can adjust different driving parameters according to different brightness to control different illuminance parameters, and when the brightness of the surrounding environment is low (the surrounding environment is very dark), the illuminance parameters of the two flashes can be improved to Clearly illuminate the surrounding environment; when the brightness of the surrounding environment is high (the surrounding environment is slightly darker), the illumination parameters of the two flashes can be appropriately reduced to avoid excessive power consumption under the premise of clear lighting and prolong the flash’s service life.

If the current application scene is a shooting scene, reference may also be made to FIG. 6 . FIG. 6 shows a schematic sub-flow diagram of a flash control method for a mobile terminal in an exemplary embodiment of the present disclosure. A schematic diagram of a sub-flow for realizing different light intensity distributions by driving parameters of the flash and/or the second flash, including steps S601-S602, the specific implementation will be explained below with reference to FIG. 6 .

In step S601, the distance between the photographed object and the mobile terminal is obtained.

In this step, the distance between the photographed object and the mobile terminal may be acquired through a distance detection unit or an infrared distance sensor of the mobile terminal.

In step S602, according to the distance, the corresponding relationship between the preset distance and the driving parameters of the first flash, the driving parameters of the first flash are adjusted; according to the corresponding relationship between the distance, the preset distance and the driving parameters of the second flash , adjust the driving parameters of the second flash.

In this step, the driving parameters of the first flash and the second flash may be automatically adjusted according to the above distance. Specifically, the corresponding relationship between the preset distance and the driving parameters of the first flash can be obtained (for example, the distance is divided into a plurality of numerical intervals, and different numerical intervals correspond to different driving currents of the first flash. Specifically, the distance can be set. The larger the value is, the larger the driving current of the first flash is), and the corresponding relationship between the preset distance and the driving parameters of the second flash is obtained (for example, the distance is divided into multiple numerical intervals, and different numerical intervals correspond to the second flash (specifically, the larger the setting distance, the larger the driving current of the second flash), and then, the driving parameters of the first flash are adjusted to the third target value, and the driving parameters of the second flash are adjusted to the third Four target values.

Exemplarily, the driving parameters of the first flash and the driving parameters of the second flash can also be adjusted according to the distance, so that the central illuminance after the light of the two is superimposed is equal or approximately equal to the surrounding illuminance (the light is evenly distributed), so as to avoid shooting scenes at night. The uneven distribution of light in the medium leads to a technical problem of local overexposure, improving the quality of the photo.

Therefore, the present disclosure can adjust different driving parameters according to different distances to control different illuminance parameters. When the distance between the shooting target and the mobile terminal is relatively far, the illuminance parameters of the two flashes can be appropriately increased to clearly Illuminate the shooting target; when the surrounding environment is relatively close, you can appropriately reduce the illumination parameters of the two flashes to avoid overexposure and affect the shooting quality.

It should be noted that the driving parameters of the first flash and the driving parameters of the second flash can also be preset under different ambient brightness and different shooting distances, so as to present different lighting conditions according to different ambient brightness and different shooting distances. Lighting effect.

If the current application scene is a lighting scene, reference may be made to FIG. 7 . FIG. 7 shows a schematic sub-flow diagram of a method for controlling a flashlight of a mobile terminal in an exemplary embodiment of the present disclosure. A schematic diagram of a sub-flow for adjusting the driving parameters of the first flasher and/or the second flasher, including steps S701-S702, the specific implementation will be explained below with reference to FIG. 7 .

In step S701, a touch operation acting on a touch screen of the mobile terminal is detected.

In this step, exemplarily, if it is detected that the user performs a touch operation on the touch screen of the mobile terminal (for example, single click, double click, etc.) in the lighting scene, the touch operation may be determined as a parameter adjustment operate.

Exemplarily, one or more parameter adjustment icons may also be displayed on the touch screen of the mobile terminal, and further, the user may perform a touch operation on the above parameter adjustment icons to adjust the first flash and/or the second flash. drive parameters. It should be noted that the touch operation may be a sliding operation, a dragging operation, or the like. Exemplarily, if the user's touch operation on the above parameter adjustment icon is not detected within a preset time period (for example: 10 seconds), the above parameter adjustment icon may also be automatically hidden to reduce the occupancy rate of the graphical user interface. .

In step S702, the driving parameters of the first flash and/or the second flash are adjusted according to the touch operation.

In this step, the driving parameters of the first flash and/or the second flash may be adjusted according to the detected touch operation.

Specifically, referring to the relevant explanation of the above step S701, exemplarily, the touch position can be detected, and when the touch position is located above the touch screen, the driving current of the first flash and/or the second flash is increased, When the touch position is located below the touch screen, the driving current of the first flash and the second flash is reduced, so that the user can easily adjust the lighting effect of the flash even when the screen is off.

Exemplarily, one or more parameter adjustment icons may also be displayed on the graphical user interface, and further, when a touch operation acting on the parameter adjustment icon is detected, the direction of the touch track can be detected. When the direction is upward, the driving parameters of the first flash and/or the second flash can be increased, and when the direction of the touch track is downward, the driving parameters of the first flash and/or the second flash can be decreased.

If the current application scene is a lighting scene, you can also refer to FIG. 8 . FIG. 8 shows a schematic sub-flow diagram of a flash control method for a mobile terminal in an exemplary embodiment of the present disclosure, and specifically shows that in the lighting scene, according to the detected adjustment button , a schematic diagram of a sub-flow for adjusting the driving parameters of the first flash and/or the second flash, including steps S801-S802, and the specific implementation is explained below with reference to FIG. 8 .

In step S801, the change of the adjustment button is detected; the adjustment button is used to adjust the driving parameters of the first flash and/or the second flash.

In this step, the change of the adjustment key (used to adjust the driving parameters of the first flash and/or the second flash) may be detected, for example, the adjustment key may be a side volume key of the mobile terminal.

In step S802, the driving parameters of the first flash and/or the second flash are adjusted according to the change of the adjustment button.

In this step, the driving parameters of the first flashing light and/or the second flashing light may be adjusted according to the detected change of the adjustment button. Exemplarily, taking the driving parameter as the driving current as an example, when it is detected that the user presses the "+" of the volume key, the driving current of the first flash and/or the second flash can be increased. When the "-" of the volume key is pressed, the driving current of the first flashing light and/or the second flashing light can be reduced, so that different lighting effects can be displayed according to different needs of users.

Exemplarily, in a lighting scene, different lighting effects can also be automatically controlled according to different scenes. Exemplarily, multiple lighting modes can be preset, and the first flash and the first flash corresponding to the different lighting modes can be set. Two driving parameters of the flash, for example, a variety of lighting modes may include: Mode A (central illuminance is greater than ambient illuminance), Mode B (central illuminance is equal to or approximately equal to ambient illuminance), Mode C (central illuminance is less than ambient illuminance), Therefore, the user can select an appropriate lighting mode according to his own needs.

For example, when the user's current actual demand is general lighting, mode B can be selected to ensure uniform lighting without glare; when the user's current actual demand is to carefully observe the shape of a certain part, thread a needle, and find something, Mode A can be selected to make the light more concentrated and facilitate the observation and search of the target.

Based on the above technical solutions, the present disclosure can not only improve the uniformity of the light intensity distribution by superimposing the light of the flash and the second flash, but also solve the technical problem of partial overexposure of night photography caused by uneven light intensity distribution in the related art, and improve the nighttime photos. the quality of the shots and the lighting effects of the photos. On the other hand, it can also present different lighting effects according to different scenes and different user needs, improve the single and dazzling problem of traditional flash light effects, and optimize the user experience.

The present disclosure also provides a mobile terminal. FIG. 9 shows a schematic structural diagram of the mobile terminal in an exemplary embodiment of the present disclosure; as shown in FIG. 9 , the mobile terminal 900 may include a detection module 901 and an adjustment module 902 . in:

The detection module 901 is configured to identify the current application scene when it is detected that the first flashlight and the second flashlight are in an on state.
