Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
In specific implementation, terminal mentioned in the embodiment of the present invention includes but not limited to: the electronic equipment such as smart mobile phone (as Android phone, IOS mobile phone), panel computer, notebook computer, palmtop PC, wearable intelligent equipment.
Below in conjunction with Fig. 1 to Fig. 5 to the embodiment of the present invention provide a kind of prevent camera from dallying method and terminal be specifically described.
See Fig. 1, be a kind of method flow schematic diagram preventing camera from dallying that the embodiment of the present invention provides, the method preventing camera from dallying as shown in the figure can comprise the following steps:
S101, receives camera rotation command, starts described camera to single direction uniform rotation.
In specific implementation, user is when needs rotating camera, and the camera application provided by terminal opens interface of taking pictures, and then operates rotating camera function, starts this camera to single direction uniform rotation.Such as this cueing track of interface display operation rotating camera of taking pictures, this track divides upper and lower both direction, and user, according to this cueing track, when inputting track upwards by touch-screen, then starts camera and rotates to direction, terminal back; When inputting downward track by touch-screen, then start camera and rotate to terminal screen direction.And for example, user can pre-set the angle on target of camera, and when terminal receives camera rotation command, terminal, according to the difference between the current angle of camera and angle on target, automatically controls camera and rotates to angle on target.
S102, obtains Hall value with Fixed Time Interval by digital hall sensor in terminal, and calculates the difference between the current Hall value that gets and the front Hall value once got.
In specific implementation, the rotating camera that electro-motor controls is provided with magnet, position corresponding with magnet on camera on the terminal body at camera place is also provided with digital hall sensor, when camera rotates, the angle of camera is in change, on camera, the distance of magnet and digital hall sensor also changes thereupon, and now the Hall value of digital hall sensor also changes along with the distance change between digital hall sensor and magnet, the anglec of rotation of camera therefore can be judged according to Hall value.
Camera is in rotary course, and terminal obtains Hall value with the digital hall sensor in fixed time interval timing reading terminals, then calculates the difference between the current Hall value that gets and the front Hall value once got.At present, the maximum anglec of rotation of common rotating camera is generally about 210 degree, if when camera is rearmounted, the angle of camera is 0 degree, time preposition, the angle of camera is 180 degree, when usual camera rotates from 0 degree to 210 directions, when the angle that camera revolves is very fast close to the change of Hall value when 180 degree, and camera from 210 degree to 0 degree rotate time, when camera rotate over 180 degree to 0 degree near time Hall value transform slower, when therefore rotating from 0 degree to 210 directions, fixed time interval can be selected shorter, and when rotating from 210 degree to 0 degree direction, fixed time interval can be selected more longer.
S103, if the number of times that the difference occurring continuously between the current Hall value that gets and the front Hall value once got is not more than the first preset value reaches default lasting number of times, then stops the rotation of described camera.
In specific implementation, a Count of Status value can be pre-set, this Count of Status value difference being used for recording between the Hall value of the current acquisition of appearance continuously and the Hall value of previous acquisition is not more than the number of times of the first preset value, and in camera rotation process, the value of this read-around ratio is: current state count value deducts Count of Status value initial value later divided by the value of fixed step size.Terminal gets Hall value in second time, just start to calculate the difference between the Hall value of current acquisition and the Hall value of previous acquisition, if this difference is not more than the first preset value, just Count of Status value is added one or increase progressively with other fixed step sizes, and when judging that Count of Status value reaches the 3rd preset value (read-around ratio reaches default lasting number of times), stop camera rotating; If this difference is greater than the first preset value, just Count of Status value is recovered initial value, and then continue to perform step S102.
In another embodiment, described method also comprises: judge whether described camera dallies in the process of single direction uniform rotation; If dally, then stop the rotation of described camera, and reduce described default lasting number of times with the numerical value of specifying.
In specific implementation, the spinfunction of terminal camera is in the process constantly used, its inner member (as electro-motor) is in continuous aging individual difference of adding terminal, although shooting head-turned angle therefore may be caused not reach theoretic maximum angle, but camera has turned motionless, just there will be idle running phenomenon.Further causing the mechanical loss of motor to prevent from dallying, now, this lasting number of times preset can be reduced when idle running occurs camera, when startup next time camera is rotated, camera rotation can be stopped before generation idle running.
Further, judge that the method whether described camera occurs to dally in the process of single direction uniform rotation specifically comprises: gather the stall sound that described camera occurs in the process of single direction uniform rotation; If the number of times that described stall sound occurs continuously reaches the second preset value, determine that described camera dallies.
In specific implementation, the sound that can send during electro-motor stall in acquisition camera when terminal is dispatched from the factory, and store, start when camera rotates user and open microphone function simultaneously, acquisition camera rotates the sound sent, the sound whether sound judging to collect by the sound recognition module in terminal sends when being electro-motor stall, and when the number of times that this stall sound occurs continuously reaches the second preset value, can think that camera dallies.
In another embodiment, before execution step S102, described method also comprises: the rotation direction judging described camera, determines the account form of the difference between the current Hall value that gets of described calculating and the front Hall value once got according to the rotation direction of described camera.
In specific implementation, camera there will be with the Digital Hall on terminal body apart from identical situation in some position in rotary course, therefore the method described in the present embodiment is adopted, when calculating the difference between the current Hall value that gets and the previous Hall value got, the account form of absolute difference should not be adopted; And account form should be determined in advance, this account form comprises the described current Hall value got and deducts the described previous Hall value that gets or the described previous Hall value got deducts the described current Hall value got.
In another embodiment, after execution step S103, described method also comprises: receive camera rotation command, start the uniform rotation round about of described camera, and described Count of Status value is recovered initial value.Perform the method described by the present embodiment, can realize, when each use camera spinfunction, can judging whether camera soon turns to maximum angle in advance, and before camera turns to maximum angle, stopping camera rotating.
Further, in another optional enforcement, the described camera of described control specifically comprises to the method for single direction uniform rotation: start the electro-motor in described camera, controls described camera to single direction uniform rotation by described electro-motor.
The embodiment of the present invention, camera rotation command can be received, start described camera to single direction uniform rotation, Hall value is obtained by the digital hall sensor in terminal with Fixed Time Interval, and the difference calculated between the current Hall value that gets and the front Hall value once got, and then when the number of times occurring that continuously the difference between the current Hall value that gets and the front Hall value once got is not more than the first preset value reaches default lasting number of times, stop the rotation of described camera, can prevent rotating camera from dallying, save the electric power resource of terminal, reduce the mechanical loss of electro-motor in rotating camera, thus increase the useful life of the spinfunction of rotating camera.
