Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the subject matter of the present disclosure can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and the like.

In the related art, a flash lamp cover is generally arranged in front of a flash lamp, and the flash lamp cover is provided with a fresnel pattern structure, which can change the illumination distribution of light emitted by the flash lamp (properly reduce the central illumination and improve the surrounding illumination), so that the light can be uniformly filled in the shooting view field of a camera. However, even if the lampshade exists, the central illumination of the flash lamp is still far greater than the ambient illumination, and the ambient illumination is only about 25% -40% of the central illumination.
Therefore, even if the driving current is increased in the case of arranging a plurality of flash lamps, only the intensity of light emission can be changed, and the display effect after light superposition is still a problem that the central illuminance is far higher than the ambient illuminance, the uneven light intensity distribution cannot be changed, and the shooting effect as in the daytime cannot be obtained.
In the embodiment of the disclosure, firstly, a flash lamp control method of a mobile terminal is provided, which overcomes the defect of uneven light intensity distribution in the related art at least to some extent.
Fig. 1 illustrates a flowchart of a flash control method of a mobile terminal in an exemplary embodiment of the present disclosure, and an execution subject of the flash control method of the mobile terminal may be a mobile terminal that controls a flash.
Referring to fig. 1, a flash control method of a mobile terminal according to one embodiment of the present disclosure includes the steps of:
step S110, when detecting that the first flash lamp and the second flash lamp are in an open state, identifying a current application scene;
and step S120, adjusting the driving parameters of the first flash lamp and the second flash lamp according to the current application scene so as to adjust the illumination parameters of the first flash lamp and the second flash lamp.
In the technical scheme that the embodiment that fig. 1 shows provided, on the one hand, through set up first flash lamp and the second flash lamp that the illuminance parameter is different on mobile terminal (specifically, the central illuminance of first flash lamp is greater than surrounding illuminance, the central illuminance of second flash lamp is less than surrounding illuminance), can be through the light stack of first flash lamp and second flash lamp, improve light distribution's homogeneity, solve among the related art because of the inhomogeneous technical problem that leads to the local overexposure of shooing night of light distribution, the visual effect of the shooting quality and the photo at night has been improved. On the other hand, when detecting that first flash lamp and second flash lamp are in the on-state, discernment current application scene to according to current application scene, adjust the drive parameter of first flash lamp and second flash lamp, with the illuminance parameter of adjusting first flash lamp and second flash lamp, can demonstrate different light efficiency of polishing according to different scenes and different user's demands, improved that traditional flash lamp light efficiency is single, dazzling problem, optimized user's use and experienced.
The following describes the specific implementation of each step in fig. 1 in detail:
the mobile terminal refers to a computer device that can be used in a mobile process, for example, the mobile terminal in the present disclosure may include a mobile phone, a notebook, a tablet computer, and the like, and may be set by itself according to an actual situation, which belongs to the protection scope of the present disclosure.
Above-mentioned mobile terminal is provided with first flash lamp and second flash lamp at least, and the lamp shade structure of first flash lamp and second flash lamp is different for the illuminance parameter (including central illuminance and surrounding illuminance) of first flash lamp and second flash lamp is different, and is exemplary, can set up the central illuminance of first flash lamp and be greater than surrounding illuminance, and the central illuminance that sets up the second flash lamp is less than surrounding illuminance. For example, an antireflection film may be further disposed on the lampshade structure of the first flash lamp and/or the second flash lamp according to actual needs, so as to increase the intensity of transmitted light. Alternatively, a transmittance reducing film may be provided on the structure of the lamp cover of the first flash lamp and/or the second flash lamp to reduce the intensity of transmitted light.
For example, 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 a positional relationship between the first flash and the second flash on the mobile terminal, referring to fig. 2, 201 shows the mobile terminal, 202 shows a camera, and the first flash 203 and the second flash 204 may be disposed around the camera 202 at a preset distance and in a left-right positional relationship, or may be disposed around the camera at a preset distance and in a top-bottom positional relationship. It should be noted that the specific number and the mutual position relationship of the flash lamps can be set according to the actual situation, and the flash lamps belong to the protection scope of the present disclosure.
For example, the central illuminance and the ambient illuminance of the first flash and the second flash under different driving parameters may be measured at different distances (measuring the distance between the position and the mobile terminal) in advance. The driving parameter may be a driving current or a driving voltage, and the following embodiments will describe the driving parameter as a driving current.
For example, fig. 3A is a schematic diagram illustrating a flash control method of a mobile terminal according to an exemplary embodiment of the disclosure, and particularly, a schematic diagram illustrating a central illuminance and a surrounding illuminance when only a first flash is turned on for target distance measurement when a driving current is 1A, and referring to fig. 3A, the central illuminance at this time is a1Ambient illuminance of B1. For example, the central illuminance A of the first flash lamp is measured at this time1100lux, ambient illuminance B120lux, with a ratio of ambient to central illumination of 1: 5.
Fig. 3B is a schematic diagram illustrating a flash control method of a mobile terminal according to an exemplary embodiment of the disclosure, and particularly, a schematic diagram illustrating a central illuminance and a peripheral illuminance of only the second flash being turned on when the driving current is 1A, as can be seen from fig. 3B, when the central illuminance is a2Ambient illuminance of B2. For example, the central illuminance A of the second flash lamp measured at this time230lux, ambient illuminance B260lux, with a ratio of ambient to central illumination of 2: 1.
Fig. 3C is a schematic diagram illustrating a flash control method of a mobile terminal in an exemplary embodiment of the disclosure, specifically illustrating that when a driving current of a first flash is I1The driving current of the second flash lamp is I2When the target distance is measured, the central illumination and the ambient illumination formed by overlapping the light of the first flash lamp and the light of the second flash lamp are shown as A1*I1+A2*I2Ambient illuminance of B1*I1+B2*I2。
Therefore, when the driving current of the first flash lamp is set to be 1A and the driving current of the second flash lamp is set to be 1A, the central illuminance formed by natural superposition may be 100 × 1+30 × 1 to 130lux, and the ambient illuminance may be 20 × 1+60 × 1 to 80lux, so that the display effect that the center is brighter than the ambient can be visually presented.
When the driving current of the first flash lamp is set to 0.9A (the measured central illuminance of the first flash lamp may be 90lux and the measured ambient illuminance may be 18lux), and the driving current of the second flash lamp is set to 1.45A (the measured central illuminance of the second flash lamp may be 43.5lux and the measured ambient illuminance may be 87lux), the central illuminance formed after natural superposition may be 90 × 0.9+43.5 × 1.45 — 144.075lux, the ambient illuminance may be 18 × 0.9+87 × 1.45 — 142.35lux, and the ratio of the ambient illuminance to the central illuminance may be 98.9%, so that the display effect that the center is approximately as bright as the periphery can be visually presented.
When the driving current of the first flash lamp is set to 0.3A (the measured central illuminance of the first flash lamp may be 30lux and the measured ambient illuminance may be 6lux) and the driving current of the second flash lamp is set to 1.3A (the measured central illuminance of the second flash lamp may be 39lux and the measured ambient illuminance may be 78lux), the central illuminance formed by natural superposition may be 30 × 0.3+39 + 1.3 — 59.7lux and the ambient illuminance may be 6 × 0.3+78 + 1.3 — 103.2lux, so that a brighter display effect than the center around can be presented.
After the relevant parameters (the driving current of the first flash lamp and the driving current of the second flash lamp) corresponding to the different lighting effects are measured, the different lighting effects and the corresponding relevant parameters can be stored in advance so as to facilitate the direct calling of the subsequent relevant processing procedures. For example, reference may be made to table 1, where table 1 shows an exemplary table in which the above-described polishing effect is stored in correspondence with the relevant parameters:
TABLE 1
It should be noted that different polishing effects may correspond to multiple sets of different related parameters, and may be set by itself in combination with actual situations, which is not particularly limited in this disclosure.
With continued reference to fig. 1, in step S110, when the first flash and the second flash are detected to be in the on state, the current application scene is identified.
In this step, when it is detected that the first flash and the second flash are in the on state, a current application scene may be identified, for example, the current application scene may include a shooting scene and a lighting scene, specifically, refer to fig. 4, where fig. 4 shows a sub-flow diagram for identifying the current application scene in an exemplary embodiment of the present disclosure, which includes steps S401 to S402, and a specific implementation manner 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 the on state and the mobile terminal is in the shooting mode, it is determined that the current application scene is the shooting scene.
In this step, if it is detected that the mobile terminal is in the shooting mode (for example, if the current display interface of the mobile terminal is a shooting interface, and a user performs a click operation on a shooting icon, etc., it is determined that the mobile terminal is in the shooting mode) under the condition that the first flash lamp and the second flash lamp are in the on state, it may be determined that the current application scene is the shooting scene.
In step S402, when it is detected that the first flash and the second flash are in the on state and the mobile terminal is in the flashlight mode, it is determined that the current application scene is the lighting scene.
In this step, under the condition that the first flash lamp and the second flash lamp are in the on state, if it is detected that the mobile terminal is in the shooting mode (for example, a display interface of the current mobile terminal is a shooting interface), it may be determined that the current application scene is the lighting scene.
With continued reference to fig. 1, in step S120, the driving parameters of the first flash and the second flash are adjusted according to the current application scenario, so as to adjust the illumination parameters of the first flash and the second flash.
In this step, for example, referring to the relevant explanation of the above step and table 1, if the current application scene is a shooting scene, the relevant parameter corresponding to "the center is as bright as the surroundings or as bright as the surroundings", that is, the driving current of the first flash lamp is set to 0.9A, and the driving current of the second flash lamp is set to 1.45A, so that a lighting effect that the center is as bright as the surroundings or as bright as the surroundings can be presented, light is uniformly distributed, local overexposure is avoided, and shooting quality is improved. If the current application scene is the lighting scene, the relevant parameters corresponding to the 'surrounding is brighter than the center' can be automatically called, namely the driving current of the first flash lamp is set to be 0.3A, and the driving current of the second flash lamp is set to be 1.3A, so that the surrounding bright polishing effect is presented, therefore, the lighting light can be prevented from being too dazzling, and the user experience is optimized. It should be noted that, the specific parameter calling setting can be set according to the actual situation, and belongs to the protection scope of the present disclosure.
If the current application scene is a shooting scene, refer to fig. 5, where fig. 5 is a sub-flow diagram illustrating a flash control method of a mobile terminal in an exemplary embodiment of the present disclosure, and specifically illustrates a sub-flow diagram that adjusts driving parameters of a first flash and a second flash according to brightness of a surrounding environment to achieve different light intensity distributions, including steps S501 to S502, and the following describes a specific implementation manner 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 by a brightness sensor (a sensor using a photoelectric device as a conversion element, which can be used to detect a non-electric quantity directly causing a change in brightness, and a sensor using a photoelectric element as a detection element) of the mobile terminal, where the brightness refers to the brightness of the picture, and is given by candela per square meter (cd/m2) or nits, that is, candles per square meter. For example, the brightness of the surrounding environment obtained in this step may be L1(candela/m squared).
For example, after the brightness of the surrounding environment is obtained, if the brightness L of the surrounding environment is determined1Greater than a brightness threshold L (preset brightness value), and also controllableThe first flash lamp and/or the second flash lamp are/is automatically turned off so as to avoid the influence on the shooting effect under the condition of higher brightness.
In step S502, adjusting a driving parameter of the first flash lamp according to the corresponding relationship between the brightness, the preset brightness, and the driving parameter of the first flash lamp; and adjusting the driving parameters of the second flash lamp according to the corresponding relation between the brightness, the preset brightness and the driving parameters of the second flash lamp.
In this step, the driving parameters of the first flash lamp and the second flash lamp can be adjusted according to the brightness of the surrounding environment. Specifically, a preset correspondence relationship between the brightness and the driving parameter of the first flash lamp may be obtained (for example, the brightness is divided into a plurality of value intervals, different value intervals correspond to different driving currents of the first flash lamp, and specifically, it may be set that the smaller the brightness, the larger the driving current of the first flash lamp is), and a preset correspondence relationship between the brightness and the driving current of the second flash lamp is obtained (for example, the brightness is divided into a plurality of value intervals, different value intervals correspond to different driving currents of the second flash lamp, and specifically, the smaller the brightness is set, the larger the driving current of the second flash lamp is set), so that the driving parameter of the first flash lamp is adjusted to a first target value, and the driving parameter of the second flash lamp is adjusted to a second target value.
Exemplarily, the driving parameters of the first flash lamp and the driving parameters of the second flash lamp can be adjusted according to the brightness, so that the central illumination of the first flash lamp and the peripheral illumination of the first flash lamp are equal or approximately equal (the light is uniformly distributed) after the light is superimposed, the technical problem that local overexposure is caused by nonuniform light distribution in a scene shot at night is avoided, and the picture shooting quality is improved.
Therefore, the method can adjust different driving parameters according to different brightness to control different illumination parameters, and can improve the illumination parameters of the two flash lamps under the condition that the brightness of the surrounding environment is low (the surrounding environment is dark) to clearly illuminate the surrounding environment; when the brightness of the surrounding environment is high (the surrounding environment is slightly dark), the illumination parameters of the two flash lamps can be properly reduced, so that the electric quantity is prevented from being excessively consumed on the premise of clear illumination, and the service life of the flash lamps is prolonged.
If the current application scenario is a shooting scenario, refer to fig. 6, where fig. 6 is a sub-flow diagram illustrating a flash control method of a mobile terminal in an exemplary embodiment of the present disclosure, and specifically illustrates a sub-flow diagram that adjusts driving parameters of a first flash and/or a second flash according to a distance between a shooting target and the mobile terminal to achieve different light intensity distributions, including steps S601-S602, and a specific implementation manner is explained below with reference to fig. 6.
In step S601, the distance between the subject and the mobile terminal is acquired.
In this step, the distance between the shooting object and the mobile terminal may be acquired by a distance detection unit or an infrared distance sensor of the mobile terminal.
In step S602, adjusting a driving parameter of the first flash lamp according to a corresponding relationship between the distance, the preset distance, and the driving parameter of the first flash lamp; and adjusting the driving parameters of the second flash lamp according to the corresponding relation among the distance, the preset distance and the driving parameters of the second flash lamp.
In this step, the driving parameters of the first flash lamp and the second flash lamp can be automatically adjusted according to the distance. Specifically, a preset corresponding relationship between the distance and the driving parameter of the first flash lamp may be obtained (for example, the distance is divided into a plurality of value sections, different value sections correspond to different driving currents of the first flash lamp, and specifically, it may be set that the larger the distance is, the larger the driving current of the first flash lamp is), and a preset corresponding relationship between the distance and the driving parameter of the second flash lamp may be obtained (for example, the distance is divided into a plurality of value sections, different value sections correspond to different driving currents of the second flash lamp, and specifically, the larger the distance is, the larger the driving current of the second flash lamp is), so that the driving parameter of the first flash lamp is adjusted to a third target value, and the driving parameter of the second flash lamp is adjusted to a fourth target value.
Exemplarily, the driving parameters of the first flash lamp and the driving parameters of the second flash lamp can be adjusted according to the distance, so that the central illumination of the first flash lamp and the peripheral illumination of the first flash lamp after the light is superimposed is equal or approximately equal (the light is uniformly distributed), the technical problem that local overexposure is caused by nonuniform light distribution in a scene shot at night is avoided, and the picture shooting quality is improved.
Therefore, the method and the device can adjust different driving parameters according to different distances so as to control different illumination parameters, and can properly improve the illumination parameters of the two flash lamps under the condition that the distance between the shooting target and the mobile terminal is longer so as to clearly illuminate the shooting target; when the distance between the surrounding environment is short, the illumination parameters of the two flash lamps can be properly reduced, so that the phenomenon that overexposure affects the shooting quality is avoided.
It should be noted that, the driving parameters of the first flash lamp and the driving parameters of the second flash lamp may also be preset under different ambient brightness and different shooting distances, so as to achieve different lighting effects according to different ambient brightness and different shooting distances.
If the current application scene is an illumination scene, refer to fig. 7, where fig. 7 shows a sub-flow diagram of a flash control method of a mobile terminal in an exemplary embodiment of the present disclosure, and specifically shows a sub-flow diagram of adjusting driving parameters of a first flash and/or a second flash according to a detected touch operation of a user in the illumination scene, including steps S701 to S702, and a specific implementation is 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, for example, if it is detected that the user performs a touch operation (e.g., a single click, a double click, etc.) on the touch screen of the mobile terminal in the lighting scene, the touch operation may be determined as a parameter adjustment operation.
For example, one or more parameter adjustment icons may be displayed on a touch screen of the mobile terminal, and then, a user may perform a touch operation on the parameter adjustment icons to adjust driving parameters of the first flash and/or the second flash. Note that the touch operation may be a slide operation, a drag operation, or the like. For example, if the touch operation of the user on the parameter adjustment icon is not detected within a preset time period (e.g., 10 seconds), the parameter adjustment icon may be automatically hidden to reduce the occupancy of the graphical user interface.
In step S702, 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 lamp and/or the second flash lamp can be adjusted according to the detected touch operation.
Specifically, referring to the above explanation related to step S701, for example, the touch position may 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, and when the touch position is located below the touch screen, the driving current of the first flash and the second flash is decreased, so that the user may conveniently adjust the lighting effect of the flash even in the screen-off state.
For example, one or more parameter adjustment icons may be displayed on the graphical user interface, and then, when a touch operation acting on the parameter adjustment icon is detected, the direction of the touch trajectory thereof may be detected, when the direction of the touch trajectory is upward, the driving parameters of the first flash lamp and/or the second flash lamp may be increased, and when the direction of the touch trajectory is downward, the driving parameters of the first flash lamp and/or the second flash lamp may be decreased.
If the current application scene is an illumination scene, refer to fig. 8, and fig. 8 shows a sub-flow diagram of a flash control method of a mobile terminal in an exemplary embodiment of the present disclosure, and specifically shows a sub-flow diagram of adjusting a driving parameter of a first flash and/or a second flash according to a detected change of an adjustment key in an illumination scene, including steps S801 to S802, and a specific implementation is explained below with reference to fig. 8.
In step S801, a change in the adjustment key is detected; the adjusting key is used for adjusting the driving parameters of the first flash lamp and/or the second flash lamp.
In this step, a change of an adjustment key (for adjusting a driving parameter of the first flash and/or the second flash) may be detected, which may be, for example, a side volume key of the mobile terminal.
In step S802, driving parameters of the first flash and/or the second flash are adjusted according to the change of the adjustment key.
In this step, the driving parameters of the first flash lamp and/or the second flash lamp can be adjusted according to the detected change of the adjusting key. For example, the driving parameter is taken as the driving current for explanation, when it is detected that the user presses "+" of the volume key, the driving current of the first flash lamp and/or the second flash lamp may be increased, and when it is detected that the user presses "-" of the volume key, the driving current of the first flash lamp and/or the second flash lamp may be decreased, so that different lighting effects may be exhibited according to different needs of the user.
