Specific embodiment
To make present disclosure more clear understandable, below in conjunction with Figure of description, present disclosure is made into oneStep explanation.Certainly the invention is not limited in the specific embodiment, the general replacement known to those skilled in the artCover within the scope of the present invention.
Fig. 1 show a kind of mobile terminal dual camera changing method flow chart of the invention, and Fig. 2 show of the inventionA kind of mobile terminal dual camera switching device, the switching device includes detection module 10, judge module 20, camera switching mouldBlock 30.The present invention is described in detail below with reference to Fig. 1 and Fig. 2.
By taking a preferred embodiment of the invention as an example, as shown in figure 1, mobile terminal dual camera changing method includes：
Step S10：Open mobile terminal camera function.
In this step, front camera and rearmounted shooting are configured with mobile terminal such as smart mobile phone, PAD or mobile PCHead.Front camera and rear camera can be respectively the combination of different types of camera, such as narrow viewing angle camera with it is commonVisual angle camera, or common view angle camera and wide viewing angle camera combination.When user opens taking pictures on mobile terminalDuring function, the display screen of mobile terminal shows the page of taking pictures, and automatically opens up any one in front camera and rear camera.It is mobile wholeEnd can open the camera for using when taking pictures last time, it is also possible to open the camera (such as rear camera) of default setting.Such asThe camera that fruit mobile terminal is opened is not that user wants, and user can carry out operations described below to switch out to mobile terminalOpen required camera.
S20：Whether detection user performs certain gestures, the certain gestures and display screen touch-control and entity key to mobile terminalPressing is unrelated.
In this step, while camera function is opened, mobile terminal dual camera switching device is also opened.The deviceDetection module 10 detects user to the gesture operation performed by mobile terminal.Judge module 20 judges the gesture of the user for detectingWhether operation is certain gestures.It should be noted that certain gestures do not include the touch control operation to mobile terminal display screen curtain,The pressing operation to mobile terminal physical button is not included.
In a specific embodiment of the invention, certain gestures in a non-contact manner along specific direction slide finger orPalm.Such as user's finger is streaked every sky from left to right or from right to left in front of the display screen of mobile terminal.If detectionModule 10 does not detect the contactless slip of user's finger, or it is not along from left to right to detect the slip of user's palmOr the direction turned left from the right side, then judge module 20 judges that the gesture of user does not meet certain gestures.Wherein certain gestures can be withIt is stored in advance in a memory module.In one embodiment, can be made using the suspension inductive pick-up of mobile terminal display screen curtainThe non-contact gesture of user is detected for detection module, the identification of user gesture is realized using suspension touching technique.AnotherIn one embodiment, it would however also be possible to employ optical sensor detects the non-contact gesture of user as detection module, using light sensingThe identification of user gesture is realized in the light change of device sensing.Preferably, optical sensor can be the light sensing of any one cameraDevice, user can be carried out in work in work or rear camera according to front camera in the front or the back side of mobile terminalGesture operation, the camera of work is the gesture of detectable user.In another embodiment, it would however also be possible to employ ligh-ranging is sensedDevice detects the non-contact gesture of user as detection module.Judge module 20 judges that the gesture of user meets certain gesturesWhen, camera handover module 30 starts corresponding camera according to the glide direction of user's finger or palm.For example when user's handRefer to that camera handover module 30 opens front camera from left to right when sky is slided, when user's finger is turned left every empty sliding from the right sideWhen dynamic, camera handover module 30 opens rear camera.
In another embodiment of the invention, certain gestures are to perform the shake for reaching parameter preset, example to mobile terminalSuch as hold mobile terminal and rock mobile terminal.If detection module 10 does not detect the shake gesture of user, or userShake gesture is not reaching to parameter preset, then, then judge module 20 judges that the gesture of user does not meet certain gestures.OneIn embodiment, the shake gesture of user can be detected as detection module using the motion sensor of mobile terminal itself.MotionSensor for example including gravity sensor, gyroscope etc., can sense the change from the kinematic parameter in three-dimensional, such asThe change of the kinematic parameters such as acceleration, speed, displacement, judge module 20 judges shake gesture of the user to mobile terminal with thisWhether certain gestures are met.Specifically, during user shakes, motion sensor also gathers the change of above-mentioned kinematic parameter.Judge module 20 can be judged the parameter for collecting, if having reached parameter preset, then it represents that this time shake is effectively shake,Otherwise it is invalid shake, it is believed that do not meet certain gestures.When judge module 20 judges that the shake gesture of user meets certain gestures,The inceptive direction that the user that camera handover module 30 is arrived according to detection module shakes starts corresponding camera.For example work as userWhen shaking mobile phone to the right at the beginning, camera handover module 30 opens front camera, when user's whipping mobile phone to the left at the beginningWhen, camera handover module 30 opens rear camera.
In sum, compared to prior art by way of touching virtual switching key and switching camera, the present inventionMobile terminal dual camera changing method can allow being switched between different cameras of user's fast free, and need notThe display screen of terminal is touched by finger or the physical button of mobile terminal is pressed, and supported that user is singlehandedOperation.User's operating experience is not only improved, and due to without virtual switching key, simplifying the page of taking pictures, increased batAccording to preview page area.
