<Embodiment>
<Camera control method>
In the present embodiment, a kind of camera control method is provided, applied to the electronic equipment with camera.The electronics
Equipment can be mobile phone, tablet computer etc..In one example, which can be as shown in Figure 1.
The camera control method, as shown in Fig. 2, including step S2100 to S2200.
Step S2100 obtains the current working status of camera.
For the electronic equipment with camera, can be provided for example, by the operating system that electronic equipment is based on
, with camera relevant application interface obtain the current working status of camera.The current working status of camera includes
Opening and closed state.
Step S2200 when camera is in opening, detected when meeting preset sample rate regularization condition, will
The first current sample rate of camera is adjusted to the second sample rate,
Wherein, sample rate regularization condition turns down condition including at least sample rate.
The sample rate of camera is that camera samples the number for obtaining image data within the preset sampling period.Work as electronics
When the camera of equipment is in opening, external image data are obtained based on preset sample rate, it after the decoding will be corresponding
External image presentation will be in the display device of electronic equipment.
In the application scenarios of augmented reality, camera is based on after sample rate obtains external image data, using carrying
For augmented reality function application program to the image data decoding of the external object after, it is (such as empty with preset virtual image
Intend animation) synthesis obtain augmented reality image, then the application program by providing augmented reality function, based on preset rendering frame
Rate, rendering are presented in the display device of electronic equipment.
Inventor has found, reduces the sample rate of camera, can't influence finally to be presented on the display device of electronic equipment
On image rendering frame per second, that is, do not interfere with and picture quality on the display apparatus be presented.
For example, it is assumed that the first sample rate based on original camera：
The camera of 1 second inner electronic equipment obtains image data：A,B,C,D,E,F,G,H,I,J,K；
The virtual animation data of application program in 1 second：a,b,c,d,e,f,g,h,i,j,k；
The augmented reality image of synthesis is presented in inner electronic equipment within 1 second：
Aa,Bb,Cc,Dd,Ee,Ff,Gg,Hh,Ii,Jj,Kk；
It turns down as after the second sample rate：
The camera of 1 second inner electronic equipment obtains image data：A,B；
The virtual animation data of application program in 1 second：a,b,c,d,e,f,g,h,i,j,k
The augmented reality image of synthesis is presented in inner electronic equipment within 1 second：
Aa,Ab,Ac,Ad,Ae,Af,Ag,Ah,Ai,Aj,Bk。
As it can be seen that by when camera is opened, when detecting that meeting sample rate turns down condition, by camera it is current first
Sample rate is turned down as the second sample rate, and the external image data obtained based on the second sample rate are synthesized with virtual image, is obtained pair
The augmented reality image answered, it is to reduce the image data that camera obtains to reduce sample rate, can't influence what is finally presented
The rendering frame per second of augmented reality image does not interfere with the picture quality of the augmented reality image of presentation.
And the sample rate of camera is reduced, the working frequency of camera can be reduced, reduces the work consumption that camera is brought
Energy.Simultaneously, it is possible to reduce the image data that camera obtains correspondingly reduces the decoding process energy consumption of image data.
In the present embodiment, by the way that when camera is opened, when detecting that meeting sample rate turns down condition, camera is worked as
The first preceding sample rate is turned down as the second sample rate, under the premise of image rendering qualities are ensured, reduces the energy consumption of electronic equipment,
Phenomena such as avoiding the occurrence of equipment heating, equipment performance decline promotes the usage experience of user.
It should be understood that the first sample rate, the second sample rate can be according to concrete application scene or engineering experience values
Setting.
Specifically, sample rate turns down the application conditions that condition applies to reduce the working frequency of camera.It can basis
Specific application scenarios are configured.
For example, in certain application scenarios (such as augmented reality application scenarios), when electronic equipment moves, camera must be with
Certain sample rate works to obtain new image data in time, and when electronic equipment does not occur mobile, the figure that camera obtains
As data do not change, working frequency can be reduced.
Sample rate turn down condition can be do not occur in the first preset duration when the camera is in opening it is pre-
If equipment moving event.First preset duration can be historical experience value or experiment simulation in corresponding application scenarios
Value, for example, the first preset duration can be 3 seconds.
Specifically, it can start timer after obtaining camera and being in opening and carry out timing, by pre-setting
Monitoring module (such as electronic equipment operating system provide monitoring interface), monitor the state of electronic equipment, arrived in timing
Up to before the first preset duration, when detecting that preset equipment moving event occurs for electronic equipment, stop timer and count again
When, otherwise, after timing reaches the first preset duration, perform the step of subsequently turning down the sample rate of camera.
Specifically, equipment moving event is that mobile event occurs for characterization of electronic equipment, can be according to specific applied field
Scape is pre-set.
For example, the displacement that equipment moving event can be the electronic equipment is more than preset displacement threshold value.Wherein, this is pre-
If displacement threshold value can be historical experience value or experiment simulation value in corresponding application scenarios,
In one example, electronic equipment also has motion sensor.The signal that can be obtained according to motion sensor, is obtained
Take the displacement of electronic equipment.
The motion sensor is can be with the sensor of detection device motion state.
For example, usually there is gyroscope (also known as angular-rate sensor) or acceleration when electronic equipment is mobile phone, in mobile phone
This kind of motion sensor is counted, signal value of the mobile phone in three axis of X, Y, Z axis can be obtained by detection, with X, Y, Z signal value
It calculates or the displacement of characterization mobile phone, specific computational methods is not limited in the present embodiment.
During practical application, after the sample rate for the camera for turning down electronic equipment, since the transformation of application scenarios images
The sample rate of head mismatches scene after transformation, for example, electronic equipment moves, the sample rate of camera is too low to be obtained in time
Take the image data after scene change.
In the present embodiment, sample rate regularization condition can also include sample rate height-regulating condition.
After the sample rate detection for turning down camera, to when meeting sample rate condition be turned up, by camera it is current first
Sample rate is turned up as the second sample rate so that the sample rate of camera can match the transformation of application scenarios, obtain scene in time
Image data after transformation ensures the usage experience of user.
The application conditions that condition applies to improve the working frequency of camera are turned up in sample rate.It can be answered according to specific
It is configured with scene.
For example, in certain application scenarios (such as augmented reality application scenarios), in the sampling for the camera for turning down electronic equipment
After rate, user's mobile electronic device can cause extraneous scene changes, and the sample rate of camera should be turned up, to ensure to obtain electricity in time
New image data after sub- equipment movement.
Therefore, it is that occurrence of equipment is moved in the second preset duration after the sample rate for turning down camera that condition, which is turned up, in sample rate
Dynamic event.Second preset duration can be historical experience value or experiment simulation value in corresponding application scenarios, for example, second
Preset duration can be 3 seconds.
Specifically, it can start timer after the sample rate of camera is turned down and carry out timing, pass through pre-set prison
Module (such as the operating system of electronic equipment provide monitoring interface) is provided, monitors the state of electronic equipment, the is reached in timing
Before two preset durations, when detecting that preset equipment moving event occurs for electronic equipment, adopting for follow-up height-regulating camera is performed
Otherwise the step of sample rate, stops timer reclocking.
Equipment moving event is that mobile event occurs for characterization of electronic equipment, can be carried out according to specific application scenarios pre-
First set.The example of equipment moving event has been specifically described above, and details are not described herein.
In augmented reality application scenarios, after the sample rate of camera is turned down, the second preset duration inner electronic equipment hair
Generating apparatus moving event, it is the second sample rate that the first current sample rate of camera, which is turned up, is obtained based on the second sample rate
External image data are synthesized with virtual image, obtain corresponding new augmented reality image in time, ensure the augmented reality of user
Experience.
In practical applications, inventor has found that, if electronic equipment continues remains stationary (not moving), camera obtains
The image taken will not change, and close camera, have no effect on the augmented reality figure presented in the display device of electronic equipment
Picture.
For example, after camera is closed：
The last frame image data that camera obtains before closing：A；
The virtual animation data of application program in 1 second：a,b,c,d,e,f,g,h,i,j,k；
The augmented reality image of synthesis is presented in inner electronic equipment within 1 second：
Aa,Ab,Ac,Ad,Ae,Af,Ag,Ah,Ai,Aj,Ak。
As it can be seen that the last frame external image data obtained before being closed based on camera are synthesized with virtual image, obtain pair
The augmented reality image answered can't influence the picture quality of the augmented reality image presented.
Therefore, in the present embodiment, after the sample rate of camera is turned down, preset camera shooting can also be met detecting
During head closedown condition, camera is closed.The last frame external image data and virtual image obtained before being closed based on camera
Synthesis, obtains corresponding augmented reality image.The power consumption for the electronic equipment that camera is brought is preferably minimized, and avoids camera long
Phenomena such as equipment heating that time service is brought, equipment performance decline promotes the usage experience of user.
Specifically, camera closedown condition applies to close the application conditions of camera.It can be according to specific application
Scene is configured.
For example, camera closedown condition can be after the sample rate for turning down the camera in third preset duration not
The equipment moving event occurs.
Third preset duration can be historical experience value or experiment simulation value in corresponding application scenarios, for example,
Three preset durations can be 3 seconds.
Specifically, after the sample rate that camera can be turned down, start timer and carry out timing, pass through pre-set monitoring
Module (such as monitoring interface of the operating system offer of electronic equipment), monitors the state of electronic equipment, third is reached in timing
Before preset duration, when detecting that preset equipment moving event occurs for electronic equipment, stop timer reclocking, it is no
Then, after timing reaches third preset duration, camera is closed.
Equipment moving event is that mobile event occurs for characterization of electronic equipment, can be carried out according to specific application scenarios pre-
First set.The example of equipment moving event has been specifically described above, and details are not described herein.
During practical application, when the camera of electronic equipment is initially in closed state or is meeting camera closedown condition
After being closed by control, it may appear that application scenarios transformation needs to reopen the situation of camera.For example, when electronic equipment is sent out again
Raw movement, camera need to obtain the new external image after variation.
Therefore, in the present embodiment, when camera is closed, detect and meet preset camera open strip
During part, camera is opened, and the sample rate of camera is set as preset initial samples rate.
Initial samples rate can be pre-set according to the engineering experience under specific application scenarios or experiment simulation.
Camera unlocking condition applies to open the application conditions of camera.It can be carried out according to specific application scenarios
Setting.
For example, camera unlocking condition can be camera when being closed in the 4th preset duration occurrence of equipment
Moving event.4th preset duration can be historical experience value or experiment simulation value in corresponding application scenarios, for example,
Four preset durations can be 3 seconds.
Specifically, after determining that camera is closed, start timer and carry out timing, pass through pre-set monitoring module
(such as monitoring interface of the operating system offer of electronic equipment) monitors the state of electronic equipment, it is default to reach the 4th in timing
Before duration, when detecting that preset equipment moving event occurs for electronic equipment, open camera and sample rate is set, otherwise,
Stop timer reclocking.
Equipment moving event is that mobile event occurs for characterization of electronic equipment, can be carried out according to specific application scenarios pre-
First set.The example of equipment moving event has been specifically described above, and details are not described herein.
In augmented reality application scenarios, after closing camera, moved in the 4th preset duration inner electronic equipment occurrence of equipment
Dynamic event, opening camera and the sample rate for setting camera are initial samples rate, the extraneous figure obtained based on initial samples rate
Picture data are synthesized with virtual image, obtain corresponding new augmented reality image in time, ensure the augmented reality experience of user.
It should be understood that the words such as " first ", " second ", " third ", " the 4th " are only intended to distinguish in the present embodiment
The term of the same type of restriction, is easy to understand, and is not intended to limitation order priority or numerical values recited.
In addition, although the example in the present embodiment is mostly by taking the application in augmented reality scene as an example, it is not meant to
The application scenarios of the present embodiment are limited, the camera control method provided in the present embodiment can be adapted for any due to electronics
Equipment camera, which works long hours, brings electronic equipment hydraulic performance decline, influences the application scenarios of user experience.
