Change the structure of terminal, improve Consumer's Experience.
The infrared transmitter control method of the embodiment of the present application is illustrated with reference to Fig. 1.
Fig. 1 is the flow chart of the infrared transmitter control method of the application one embodiment.
As shown in figure 1, this method is applied to have close in function and the terminal of infrared light filling function, including：
Step 101, the current use state of terminal and/or the luminous intensity of place environment are determined.
Wherein, infrared transmitter control method provided in an embodiment of the present invention, can be configured in arbitrarily has close to work(
Performed in the terminal of energy and infrared light filling function.Wherein, the type of terminal is a lot, can be selected according to using needs, example
Such as：Mobile phone, computer etc..
Wherein, use state, can be that take pictures state, non-front camera of front camera is taken pictures state etc..
It should be noted that the state of taking pictures in the embodiment of the present invention, the camera for referring to terminal is in the state opened；It is non-
Take pictures state, the camera for referring to terminal is in the state closed.
Step 102, according to the current use state of terminal and/or the luminous intensity of place environment, the first infrared emission is determined
The objective emission pattern of device.
Wherein, emission mode, can the tranmitting frequency including the first infrared transmitter, lighting angle, the speckle number of transmitting
Amount, operating current and/or operating voltage etc..
Step 103, according to objective emission pattern, control the first infrared transmitter transmitting infrared light.
It is understood that infrared light filling function is different with the requirement close to function to the transmission power of infrared transmitter.
Infrared light filling function requires that infrared transmitter launches infrared light with larger lighting angle；And close to function, only need infrared emission
Device launches infrared light with less lighting angle.Therefore, in embodiments of the present invention, for the same infrared emission of utilization
Device realizes infrared light filling function and close to function, can set the first infrared transmitter in the terminal, infrared by control first
Transmitter launches infrared light with different emission modes, so as to realize different functions.Wherein, different emission modes is corresponding not
Same lighting angle.
Specifically, due to terminal use state and/or place environment luminous intensity difference when, terminal needs the work(realized
Can be different, for example when the luminous intensity of environment where the state of taking pictures and terminal is smaller, terminal needs to realize infrared light filling function；
When the luminous intensity of environment where exposal model and terminal is larger, or during non-exposal model, without realizing infrared light filling function,
It need to only realize close to function.Therefore, can according to the use state of terminal and/or the luminous intensity of place environment, it is determined that with
Which kind of emission mode transmitting infrared light, with function corresponding to the realization under different use states.
During specific implementation, the use state of terminal and/or the luminous intensity of place environment and first infrared can be pre-set
The corresponding relation of the emission mode of transmitter, so as to it is determined that the current use state of terminal and/or the luminous intensity of place environment
Afterwards, can be determined according to default corresponding relation corresponding to the current use state of terminal and/or the luminous intensity of place environment
The objective emission pattern of one infrared transmitter, so as to according to objective emission pattern, control the first infrared transmitter transmitting infrared light.
Wherein, terminal is in different usage situations and/or during the luminous intensity difference of place environment, corresponding first infrared hair
The emission mode of emitter, can be according under different use states and/or during the luminous intensity difference of place environment, and terminal needs to realize
Function determine.
Such as luminous intensity that the use state of terminal is the state of taking pictures and place environment it is smaller when, terminal needs to realize red
Outer light filling function, and infrared light filling function needs infrared transmitter to launch infrared light with larger lighting angle, then can set
Corresponding emission mode is that infrared transmitter launches infrared light with larger lighting angle.And the use state of terminal is shape of taking pictures
State and the luminous intensity of place environment is larger or the use state of terminal for it is non-take pictures state when, due to need to only realize close to function,
Emission mode corresponding to can then setting is that the first infrared transmitter launches infrared light with less lighting angle.
It should be noted that because terminal is close to function, what is generally detected is external object apart from terminal touch screen
Distance, therefore, the first infrared transmitter in the embodiment of the present invention, it can be arranged on below the touch-screen of terminal front side.
During specific implementation, the use state of terminal can be set to be taken pictures state and local environment light intensity for front camera
When degree is less than threshold value, corresponding emission mode is first mode；The use state of terminal is taken pictures state and institute for front camera
When place's ambient light intensity is more than threshold value, corresponding emission mode is second mode；The use state of terminal is non-front camera
During state of taking pictures, corresponding emission mode is second mode.Corresponding, step 102 determines the target hair of the first infrared transmitter
Emission mode, including：
State is taken pictures if the current use state of terminal is front camera and local environment luminous intensity is less than threshold value,
Determine that the first infrared transmitter launches infrared light in the first pattern；
Or if the current use state of terminal takes pictures state for front camera and local environment luminous intensity is more than threshold
Value, it is determined that the first infrared transmitter lights in a second mode；
Or if the current use state of terminal is taken pictures state for non-front camera, it is determined that the first infrared transmitter
Light in a second mode.
Wherein, first mode, it is the larger pattern of lighting angle, second mode, is the less pattern of lighting angle.
Threshold value, it can be arranged as required to.
Specifically, whether camera open command can be received according to terminal, determine that the current use state of terminal is
State of taking pictures or non-state of taking pictures.
Wherein, camera open command, can be the phonetic order of user, as user says " I will take pictures " to terminal, or
The instruction that person or user are triggered by touch control operations such as click, long-press or slips, is not restricted herein.
During specific implementation, if terminal receives camera open command, it can determine that the current use state of terminal is
Take pictures state, if not receiving camera open command, or receive camera out code, then can determine that terminal is current
Use state is non-state of taking pictures.
Further, the camera switching command that can be received according to terminal, it is determined whether taken pictures for front camera.
Specifically, it is determined that the current use state of terminal is taken pictures state and local environment luminous intensity for front camera
During less than threshold value, due to needing to carry out light filling, then the first infrared transmitter can be controlled to launch infrared light in the first pattern, with reality
The infrared light filling function of existing terminal；It is determined that the current use state of terminal is taken pictures state and local environment for front camera
When luminous intensity is more than threshold value, or the current use state of terminal for non-front camera take pictures state when, due to that need not be mended
Light, then the first infrared transmitter can be controlled to launch infrared light in a second mode, with realize terminal close to function.
It should be noted that because the lighting angle of first mode is larger, it is higher so as to the luminous power of first mode, because
This when the current use state of terminal is that front camera exposal model and local environment luminous intensity are less than threshold value, if first
Infrared transmitter launches infrared light in the first pattern always, and power consumption can be caused larger.In embodiments of the present invention, in order to subtract
Small-power is lost, and can set the first infrared transmitter alternate emission infrared light in the first mode and a second mode successively.That is, walk
Rapid 102 can include：
State is taken pictures if the current use state of terminal is front camera and local environment luminous intensity is less than threshold value,
The first infrared transmitter alternate emission infrared light in the first mode and a second mode successively is determined, wherein, first mode and second
The lighting angle of pattern is different.
Wherein, first mode and the alternating frequency of second mode can be arranged as required to.
By being that front camera takes pictures state and local environment luminous intensity is less than threshold value in the current use state of terminal
When, the first infrared transmitter of control alternate emission infrared light in the first mode and a second mode successively, ensureing that terminal can be real
While existing infrared light filling function, low power loss can be subtracted again.
Further, in order to avoid being that front camera is taken pictures state and local environment in the current use state of terminal
When luminous intensity is less than threshold value, alternate emission infrared light in the first mode and a second mode successively, in fact it could happen that at the moment of taking pictures,
One infrared transmitter launches the situation of infrared light in a second mode just, so as to the effect for the moment infrared light filling function that causes to take pictures
It is poor, in embodiments of the present invention, front camera can be arranged on and taken pictures the moment, the first infrared transmitter of control is with the first mould
Formula launches infrared light, and before and after front camera takes pictures the moment, still controls the first infrared transmitter successively in the first pattern
With second mode alternate emission infrared light.
Or in a kind of possible way of realization, the first infrared transmitter can be controlled when front camera is taken pictures
Carve, launch infrared light in the first pattern, before and after front camera takes pictures the moment, launch infrared light in a second mode, so as to
Subtract low power loss to greatest extent.
That is, it is determined that the first infrared transmitter successively in the first mode and a second mode after alternate emission infrared light, also
It can include：
When getting photographing instruction, control first transmitter lights in the first pattern；
After image is got, control first transmitter lights in a second mode.
Wherein, the lighting angle of second mode is less than the lighting angle of first mode.
Infrared transmitter control method provided in an embodiment of the present invention, it is determined that the current use state of terminal and/or institute
After the luminous intensity of environment, pass through basis target corresponding with the luminous intensity of use state and/or place environment that terminal is current
Emission mode, control infrared transmitter transmitting infrared light, is realized and is realized using same infrared transmitter close to function and red
Outer light filling function, the space-consuming of infrared transmitter is reduced, has saved the manufacturing cost of terminal, simplify the structure of terminal,
Improve Consumer's Experience.
It is that front camera is taken pictures state and local environment in the current use state of terminal by above-mentioned analysis
When luminous intensity is less than threshold value, can by control the first infrared transmitter in the first pattern or successively in the first pattern with the second mould
Formula alternate emission infrared light, so as to realize infrared light filling function.In actual applications, the current use state of terminal is taken the photograph to be preposition
As head takes pictures state and when local environment luminous intensity is less than threshold value, infrared light filling function can also be realized simultaneously and close to function.
With reference to Fig. 2, the above situation is described in detail.
Fig. 2 is the flow chart of the infrared transmitter control method of another embodiment of the present invention.
As shown in Fig. 2 can also include proximity transducer in the terminal, the infrared transmitter control method includes：
Step 201, determine the current use state of terminal for front camera take pictures state and local environment luminous intensity it is small
In threshold value.
Step 202, according to the current use state of terminal and the luminous intensity of place environment, the first infrared transmitter is determined
Objective emission pattern is first mode.
Step 203, the first infrared transmitter of control launches infrared light in the first pattern.
Wherein, above-mentioned steps 201-203 specific implementation process and principle, it is referred to retouching in detail for above-described embodiment
State, do not repeat herein.
Step 204, the infrared luminous intensity obtained according to proximity transducer, determines the distance between active user and terminal.
It is understood that when user is taken pictures using front camera, the first infrared transmitter transmitting infrared light
Afterwards, a part of infrared light can reflex to proximity transducer by the touch-screen of terminal, and some infrared light can pass through terminal
Touch-screen reflexes to proximity transducer by user.The infrared light that the user that proximity transducer can be got according to it reflects
Intensity, determine the distance of user and terminal.
Specifically, the infrared luminous intensity of proximity transducer acquisition according to the use environment of terminal, can be pre-set, and use
The corresponding relation of the distance between family and terminal, can basis after the infrared light that user's reflection is got so as to proximity transducer
The infrared luminous intensity currently obtained, determines the distance between active user and terminal.
Step 205, according to distance, first mode is adjusted.
Specifically, because light has a transmission loss in communication process, and transmission loss is to apart from directly proportional, that is to say
Say, the distance between active user and terminal farther out when, the transmission loss of light is larger.Therefore, when terminal and subject
The distance between farther out when, can by increase the first infrared transmitter operating voltage or operating current, or increase transmitting
The mode of the suitably transmission power of increase first mode such as speckle count, to ensure light filling effect.
Further, when the distance between terminal and subject is nearer, because the infrared ray of light filling is low-angle
Area source, and it is closer to the distance when, low-angle area source may can only cover the sub-fraction of object, and can not realize larger
The light filling of scope, therefore in order to ensure light filling effect, the lighting angle of the first infrared transmitter can be increased.
In addition, the current use state of terminal takes pictures state for front camera and local environment luminous intensity is less than threshold value
When, if controlling the first infrared transmitter alternate emission infrared light in the first mode and a second mode, can also utilize close to sensing
Device, the distance between active user and terminal are determined, and according to distance, first mode and/or second mode are adjusted.
That is, step 202 and step 203 can replace with respectively：
According to the current use state of terminal and the luminous intensity of place environment, determine the first infrared transmitter successively with first
Pattern and second mode alternate emission infrared light；
Control the first infrared transmitter alternate emission infrared light in the first mode and a second mode successively.
It should be noted that in a kind of possible way of realization, the second infrared transmitter can also be set in the terminal,
Make terminal that there is structure light camera function.
Specifically, can be according to the current use state of terminal, it is determined whether start the second infrared transmitter, to realize end
The structure light camera function at end.
During specific implementation, when the current use state of terminal takes pictures state for front camera, in order to utilize structure light
Imaged, can now start the second infrared transmitter；In other situations, then the second infrared transmitter is not started.
That is, infrared transmitter control method provided in an embodiment of the present invention, can also include：
Taken pictures state if the current use state of terminal is front camera, start the second infrared transmitter.
It should be noted that transmission loss during due to infrared light emission to subject be present, and transmission loss
To apart from directly proportional, in other words, when the distance between active user and terminal is nearer, the transmission loss very little of infrared light.
At this point it is possible on the premise of the effect of structure light camera function is ensured, by the operating voltage for reducing the second infrared transmitter
Or operating current, or reduce the speckle count of transmitting etc., the mode of the appropriate transmission power for reducing first mode, to reduce power
Loss.
Accordingly, when the distance between user and terminal farther out when, then can pass through increase the second infrared transmitter work
Make voltage or operating current, or speckle count of increase transmitting etc., the mode of the appropriate transmission power for increasing first mode, to protect
Demonstrate,prove the effect of structure light camera function.
That is, after the second infrared transmitter is started, can also include：
The infrared luminous intensity obtained according to proximity transducer, determines the distance between active user and terminal；
According to distance, the emission mode of the second infrared transmitter is adjusted.
Specifically, can be as needed, be positioned proximate to sensor only obtain it is anti-by user after the transmitting of the first infrared transmitter
The infrared light penetrated, or the infrared light reflected after the transmitting of the second infrared transmitter by user is only obtained, or acquisition first is infrared simultaneously
The infrared light reflected after transmitter and the transmitting of the second infrared transmitter by user.And according to the use environment of terminal, pre-set
When proximity transducer obtains first, second or obtains the infrared light of the first and second infrared transmitters transmitting simultaneously, infrared light intensity
The corresponding relation of the distance between degree, user and terminal, so that after the infrared light that proximity transducer gets user's reflection,
The distance between active user and terminal can be determined according to the infrared luminous intensity currently obtained, then according to distance, adjustment the
The transmission power of two infrared transmitters.
Infrared transmitter control method provided in an embodiment of the present invention, it is determined that the current use state of terminal is taken the photograph to be preposition
As head takes pictures state and when local environment luminous intensity is less than threshold value, by according to the use state current with terminal and residing
First mode corresponding to ambient light intensity launches infrared light, the infrared luminous intensity then obtained according to proximity transducer, it is determined that working as
The distance between preceding user and terminal, so as to according to distance, be adjusted to first mode.Realize and utilize same infrared hair
Emitter is realized close to function and infrared light filling function, is reduced the space-consuming of infrared transmitter, has been saved being manufactured into for terminal
This, simplifies the structure of terminal, improves Consumer's Experience.
Further aspect of the present invention embodiment also proposes a kind of terminal.
Fig. 3 is the structure chart for the terminal that the application one embodiment provides.
Wherein, the type of terminal is a lot, can be selected according to using needs, such as：Mobile phone, computer etc..Fig. 3 is with end
Hold and illustrated for mobile phone.
As shown in figure 3, the terminal includes：Processor 31, memory 32 and infrared transmitter 33.
Wherein, memory 32 is used to store executable program code；Infrared transmitter 33 is used to launch infrared light；Processor
31 by reading the executable program code stored in memory 32, to realize such as the infrared transmitter control in previous embodiment
Method.
Specifically, infrared transmitter can be open-celled structure or non-open-celled structure, it is not limited herein.
, accordingly, in terminal can be with when infrared transmitter 33 is open-celled structure in a kind of possible way of realization
Proximity transducer including open-celled structure, now, the edge of infrared transmitter 33 and the center spacing of proximity transducer are more than 2 millis
Rice.
Wherein, the open-celled structure of infrared transmitter 33, which refers to apply on the touch-screen on the top of infrared transmitter 33, can allow infrared ray
By the infrared ray ink for blocking visible light and ultraviolet, receiver open-celled structure refers to the filter in proximity transducer
Upper painting can allow infrared ray to pass through the infrared ray ink of blocking visible light and ultraviolet.
It is understood that the infrared light that infrared transmitter 33 is launched, a part can be reflected by the touch-screen of terminal,
Sensor acquisition is approached, some can pass through the touch-screen of terminal, when there is external object close to touch-screen, through tactile
Proximity transducer can be reflected to by touching a part of infrared light of screen.Proximity transducer is mainly reflected red by the detection external world
Outer light, it may be determined that the distance of external object and terminal.
Because infrared transmitter 33 and proximity transducer are open-celled structure, therefore the infrared light that infrared transmitter 33 is launched is only
There is very small percentage to be reflected by the touch-screen of terminal, the touch-screen of terminal can be largely passed through, so as to which proximity transducer leads to
The infrared light that detection is reflected by external object is crossed, can accurately determine the distance of external object and terminal.Now, infrared hair
Emitter 33 and the distance of proximity transducer, little to the influence close to sensor instrument distance, therefore, infrared transmitter 33 passes with close
The distance of sensor, it can be arranged as required to.
In embodiments of the present invention, the in small distance such as infrared of infrared transmitter 33 and proximity transducer can be set
The edge of transmitter 33 and the center spacing of proximity transducer are more than 2 millimeters, to reduce infrared transmitter 33 and proximity transducer
Space-consuming.
In alternatively possible way of realization, when infrared transmitter 33 is non-open-celled structure, accordingly, in terminal also
The proximity transducer of non-open-celled structure can be included.
The edge of infrared transmitter 33 and the center spacing of proximity transducer are more than 7 millimeters.
Wherein, 33 non-open-celled structure of infrared transmitter refers to that painting can block red on the touch-screen on the top of infrared transmitter 33
The white ink of outside line or other ink, the non-open-celled structure of receiver refer to that painting can block red on the filter of proximity transducer
The white ink of outside line or other ink.
Because infrared transmitter 33 and proximity transducer are non-open-celled structure, therefore the infrared light that infrared transmitter 33 is launched
Major part can be reflected by the touch-screen of terminal, and only fraction can pass through the touch-screen of terminal, i.e. proximity transducer obtains red
Outer light, most of is the infrared light reflected by the touch-screen of terminal, so as to which proximity transducer can not be by detecting by external object
The infrared light reflected, the accurate distance for determining external object and terminal.
In embodiments of the present invention, in order to improve proximity transducer determine external object and terminal apart from when it is accurate
Property, the distance of infrared transmitter 33 and proximity transducer can be set slightly larger, for example the edge of infrared transmitter 33 passes with close
The center spacing of sensor is more than 7 millimeters, so that the infrared light by terminal touch screen reflection that proximity transducer receives is less,
To reduce the infrared light of the touch-screen of terminal reflection to the influence close to sensor instrument distance.
It should be noted that proximity transducer provided in an embodiment of the present invention, can be that the infrared proximity being separately provided passes
The two-in-one sensor that sensor or infrared proximity transducer are made jointly with photosensitive sensors, is not restricted herein.
In addition, the end in the embodiment of the present invention is also applied in previous embodiment to the explanation of infrared transmitter control method
End, here is omitted.
The terminal that the embodiment of the present application provides, pass through the light according to the use state and/or local environment current with terminal
Objective emission pattern corresponding to intensity, control infrared transmitter transmitting infrared light, is realized real using same infrared transmitter
Now close to function and infrared light filling function, the space-consuming of infrared transmitter is reduced, has saved the manufacturing cost of terminal, simplified
The structure of terminal, improves Consumer's Experience.
The embodiment of the present application also proposes a kind of computer-readable recording medium, is stored thereon with computer program, when the journey
Realized when sequence is executed by processor such as the infrared transmitter control method in previous embodiment.
