Detailed description of the invention
Embodiments of the present invention are described below in detail, and the example of described embodiment is shown in the drawings, the most identical or
Similar label represents same or similar element from start to finish or has the element of same or like function.Below by ginseng
Examine accompanying drawing describe embodiment be exemplary, be only used for explain embodiments of the present invention, and it is not intended that to this
The restriction of the embodiment of invention.
Refer to Fig. 1, the control method of embodiment of the present invention, it is used for controlling imaging device.Imaging device is applied to electricity
Sub-device, electronic installation includes touch screen.
Control method includes step:
S10, obtains imaging device current exposure value；And
S20, determines exposure bias value according to user's touch control operation on touch screen；And
S30, determines the exposure value of imaging device according to current exposure value and exposure bias value.
Referring to Fig. 2, the control device 100 of embodiment of the present invention includes acquiring unit 10, processing unit 20 and control
Unit 30 processed.As an example, the control method of embodiment of the present invention can be realized by controlling device 100, can be applicable to
Electronic installation 1000 also is used for controlling electronic installation 1000.Electronic installation 1000 can include controlling device 100, imaging
Device 200 and touch screen 300.
Wherein, step S10 of the control method of embodiment of the present invention can be realized by acquiring unit 10, step S20
Can be realized by processing unit 20, and step S30 can be realized by control unit 30.In other words, acquiring unit 10
For obtaining imaging device 200 current exposure value.Processing unit 20 is for according to user touch-control behaviour on touch screen 300
Make to determine exposure bias value.Control unit 30 for determining the exposure of imaging device 200 according to current exposure value and exposure bias value
Light value.
Generally, in imaging process, first have to wait that preview screen brightness completes automatically to adjust, that is to say that wait automatic exposure is steady
Fixed.Exposure compensating is a kind of control mode to exposure process, that is to say that the exposure value being used automatic exposure is adjusted,
Thus meet user's demand to picture brightness light and shade.Such as, when picture brightness is dark, exposure value can be increased, and work as picture
Time brighter, can less exposure value.
Exposure bias value includes positive offset and negative offset, and positive offset represents increase exposure, and negative offset represents minimizing exposure,
The absolute value of offset is the biggest, and the variable quantity of regulation is the biggest, that is to say that picture regulates the brightest or the darkest.
When user dissatisfied to the exposure of preview screen (crossing dark or overexposure), then can touch control operation on touch screen 300
Regulation exposure bias value.Current exposure value when final exposure value then completes according to automatic exposure and the touch-control according to user are grasped
The exposure bias value making to determine determines.That is to say that exposure value is equal to current exposure value with exposure value offset and or poor.
In sum, the control method of embodiment of the present invention, control device 100 and electronic installation 1000, can according to
Family compensates the regulation image with acquisition satisfaction to the operation of touch screen 300 to current exposure value, simple to operate, convenient
User operation.
In some embodiments, electronic installation 1000 can be mobile phone or panel computer.Imaging device 200 includes preposition phase
Machine and/or rearmounted camera.
It is appreciated that electronic installation 1000 includes but not limited to the example of present embodiment.
In some embodiments, touch screen 300 includes pressure transducer 310, and step S20 passes at pressure according to user
Touch control operation on sensor 310 determines exposure bias value.
Specifically, owing to touch screen 300 includes pressure transducer 310, therefore can detect that user presses touch screen 300
Operation, such as press surging, compressing time etc..Processing unit 20 will be able to be exposed according to the operation that user is concrete
The regulation of offset.
Referring to Fig. 3, specifically, in some embodiments, step S20 includes:
The pressure size being applied on pressure transducer according to user determines the rate of change of exposure bias value, and pressure is the biggest, exposure
Offset change is the fastest.
Pressure transducer 310 is able to detect that user presses the operation of touch screen 300, therefore can be by the tune of exposure bias value
Save the operation with pressure transducer 310 to be associated, will be to exposure bias value when user presses touch screen 310 when detecting
Be adjusted, and it is relevant to the rate of change of exposure bias value to press surging, such as, when pressure is the biggest, exposure is mended
Repay value change the fastest.As a example by exposure bias value forward regulates, 0 is acquiescence initial value, is not the most exposed compensating, directly
Connect employing current exposure value imaging.When with the pressure press pressure sensor 310 of dynamics F1, exposure bias value will be with
Each 0.2 unit carries out positive change, and when with the pressure press pressure sensor 310 of dynamics F2 more than F1,
Exposure bias value will carry out positive change with each 0.3 unit.And for example, exposure bias value when dispatching from the factory preset+0.3,
6 forward regulation stalls such as+0.7 ,+1.0 ,+1.3 ,+1.7 and+2.0, when the pressure with dynamics F2 more than F1
During press pressure sensor 310, compared to pressure F1, under the effect of pressure F2, exposure bias value will be at shorter time
Inside reach required gear.
It should be noted that the gear of exposure bias value arranges the side of setting included but not limited to disclosed in present embodiment
Formula.Change numerical value is also only used as schematically illustrating.
Referring to Fig. 4, specifically, in some embodiments, step S20 includes:
The direction of the pressure being applied on pressure transducer according to user determines the change direction of exposure bias value, the edge, direction of pressure
During first direction, exposure bias value positive change, when the direction of pressure is along contrary with first direction second direction, exposure compensating
Value negative sense change.
Owing to exposure value offset includes positive offset and negative offset, therefore when regulation, it is thus necessary to determine that positive negative regulator side
To.In operation, can the either direction of initialization system be positive direction, when user is applied to the pressure on pressure transducer 310
When direction is consistent with the positive direction of setting, then forward regulates exposure bias value, and when user is applied on pressure transducer 310
Pressure direction contrary with the positive direction of setting time then negative regulation exposure bias value.User can use the mode of slip to press
Power is applied on pressure transducer 310.And during sliding, pressure transducer 310 can be applied dynamics different
Pressure.To regulate the rate of change of exposure bias value.
Certainly, during regulation, it is possible to use stagewise action, the most first slide and determine the change direction of exposure bias value,
Afterwards pressure transducer 310 is applied different pressures to be adjusted exposure bias value.
Referring to Fig. 5, in some embodiments, control method includes step:
S40, controls touch screen display exposure bias value/and or exposure value.
In some embodiments, control device 100 to include showing control unit 40.Step S40 can be by display control
Unit 40 realizes.Show that control unit 40 is used for controlling touch screen 300 and shows exposure bias value/and or exposure in other words
Value.
Referring to Fig. 6, specifically, exposure bias value can show with the pattern such as bar shaped or disc, and by final
Exposure value shows in digital form.So, user will be facilitated to know the regulation process of exposure bias value and finally become
The exposure value used during picture.
It should be noted that the display format of exposure bias value includes but not limited to the mode that present embodiment discloses.
