Below in conjunction with drawings and Examples, the present invention is described in further detail.Be understandable that, specific embodiment described herein is only for explaining the present invention, but not limitation of the invention.It also should be noted that, for convenience of description, illustrate only part related to the present invention in accompanying drawing but not entire infrastructure.
Embodiment one
A kind of flow chart opening the method for mobile terminal camera function that Fig. 1 provides for the embodiment of the present invention one, the present embodiment is applicable to be avoided under mobile terminal in standby state, open by mistake the situation opening camera function, the method can be performed by the device opening mobile terminal camera function, this device is configured in mobile terminal, is realized by the mode of hardware and/or software.The method of described unlatching mobile terminal camera function specifically comprises the steps:
The gesture that under step 110, acquisition holding state, user inputs on terminal touch screen.
Wherein, described holding state is program (also may comprise micro-letter, navigation or game supervisor according to the service condition of user) and the touch control gesture handling procedure of the backstage only operational system critical processes of mobile terminal, and close the state of screen, wherein, when being in the state that idle screen is closed, mobile terminal support detects the function of the touch control gesture on screen.Described gesture is the track that the finger of user slides on the screen of the mobile terminal.
Mobile terminal in the standby state, periodically detects screen according to the periodic quantity preset and determines whether the gesture that user inputs.Such as, the variable quantity of the signal of telecommunication that the finger touch screen that mobile terminal can detect user by touch sensor causes, determine whether that the finger of user acts on the screen of mobile terminal, and when detecting that the finger of user acts on screen, determine the track that current finger slides on screen.Such as, mobile terminal closes the backlight of touch-screen in the standby state, makes touch-screen be in closed condition to reduce the power consumption of mobile terminal.But capacitive touch sensors is now still in running order, its according to preset the periodic sense terminals touch-screen of periodic quantity electrode on whether there is curent change.When the finger touch terminal touch screen of user, due to the effect of human body electric field, user and touch screen surface form a coupling capacitance.For high-frequency current, electric capacity is direct conductor, so finger siphons away a very little electric current from touch point.Flow out from the electrode the corner of touch-screen respectively according to the electric current siphoned away from touch point by finger again, and the principle that the electric current flowing through these four electrodes is directly proportional to the distance pointing corner, mobile terminal, by the accurate Calculation of the current ratio to these four electrodes outflows, draws the position of touch point.Connect each touch point successively according to the sequencing of position touch point being detected and obtain the track that current finger slides on screen.
Step 120, described gesture is opened gesture mate with the shooting preset.
Wherein, gesture is opened in described shooting is the gesture that under holding state, triggering mobile terminals starts camera function.The selection template that mobile terminal provides shooting to open gesture therefrom selects to open the gesture of camera function for user, what additionally provide personalized shooting unlatching gesture arranges function, and user can arrange according to the use habit of oneself and open shooting unlatching gesture corresponding to camera function.Mobile terminal will detect that the gesture that user inputs is opened gesture with the shooting of opening camera function under the holding state preset and mated; If described gesture and described shooting are opened gesture and matched, then determine that matching result is that the match is successful.If described gesture is opened gesture do not mate with described shooting, then determine that matching result is that it fails to match.When it fails to match, abandon carrying out response process to the gesture of user's input.
Step 130, when the match is successful, perform the operation of detection side bonded state, determine whether to open camera function according to testing result.
Wherein, side switch can be volume key, comprises volume and adds key and volume down key.The matching result opening gesture in above-mentioned gesture and the shooting preset be when the match is successful, starts volume in the side switch detection judge module detection volume key in mobile terminal and adds key or whether volume down key is pressed; If described volume adds key or volume down key is in the state be pressed, then open camera function.If described volume adds key or volume down key is not in the state be pressed, then determine that the gesture that user inputs is invalid, do not perform the operation of opening camera function.Such as, by default, the sampling resistor that volume adds key corresponding is in high level state, user press volume add key time, described sampling resistor is connected be in low level state with ground.When mobile terminal is in holding state, closes side switch and detect judge module, the process chip performing side switch detection judgement processes without the need to the signal of telecommunication gathering sampling resistor, reduces system power dissipation.Detect gesture that user inputs and the shooting preset opens gesture match time, restart side switch and detect judge module and carry out secondary detection, eliminating opens by mistake the situation opening camera function.If user pre-sets shooting and opens gesture and volume and add bond and closes the camera function starting mobile terminal, then detected the magnitude of voltage of judge module collection sampling resistor by side switch, and described magnitude of voltage and default threshold voltage are made comparisons.If described magnitude of voltage is more than or equal to default threshold voltage, then illustrate that volume adds key and is not pressed.Now, determine that described gesture is invalid, do not perform the operation of opening camera function.If described magnitude of voltage is less than default threshold voltage, then illustrate that volume adds key and is pressed.Now, mobile terminal opens gesture startup camera function according to shooting.
The technical scheme of the present embodiment, by the gesture that user under acquisition holding state inputs on terminal touch screen, described gesture is opened gesture with the shooting preset mate, when the match is successful, perform the operation of detection side bonded state, determine whether to open camera function according to testing result, solve in prior art and open camera and problem that the application of the flying power and user that affect mobile terminal is experienced because opening by mistake, it is accurate in the standby state to realize, open camera function fast, reach to reduce and open by mistake the probability opening camera function event, improve the effect that user applies the flying power of experience and mobile terminal.
Embodiment two
Fig. 2 is a kind of flow chart opening the method for mobile terminal camera function in the embodiment of the present invention two.The method of described unlatching mobile terminal camera function specifically comprises the steps:
The blank screen gesture of step 210, acquisition user input.
In the standby state, the capacitive touch sensors of mobile terminal detects the current change quantity produced at the electrode place of the screen of terminal when the finger contact screen of user, determines the position of the finger touch point on a terminal screen of user according to described current change quantity.Mobile terminal is according to the blank screen gesture that the time sequencing of described touch point connects described touch point and inputs on terminal touch screen to determine user being detected, wherein, blank screen gesture can be the track that slide in optional position on screen, and track can be letter, numeral or figure etc.
Whether step 220, detection blank screen gesture are that gesture is opened in shooting, if so, then perform step 230, if not, then perform step 240.
The blank screen gesture detected is opened gesture with the shooting preset and is mated by mobile terminal.Match if this blank screen gesture opens gesture with shooting, then perform step 230.Do not mate if this blank screen gesture opens gesture with shooting, then perform step 240.Such as, mobile terminal detects that the blank screen gesture that user inputs on terminal touch screen is English alphabet " S ", inquires about the shooting pre-set open gesture according to described blank screen gesture.If gesture is opened in the shooting pre-set comprise English alphabet " S ", then the blank screen gesture that current input is described and the shooting pre-set are opened gesture and are matched, then perform step 230.If gesture is opened in the shooting pre-set do not comprise English alphabet " S ", then illustrate that the blank screen gesture of current input and the shooting pre-set are opened gesture and do not mated, then perform step 240.
Step 230, startup side switch detect judge module.
In the standby state, the side switch of mobile terminal detects judge module and is in closed condition to reduce the power consumption of mobile terminal.When mobile terminal detects that the gesture that user inputs on terminal touch screen opens gesture for shooting, mobile terminal starts side switch and detects judge module.Detect judge module detection user by side switch and whether press side switch.If detect, user presses side switch, then described side switch detection judge module returns confirmation signal to the process chip of mobile terminal.If do not detect, user presses side switch, then described side switch detection judge module returns negative acknowledge character (NAK) to the process chip of mobile terminal.Such as, shooting is set user and opens gesture and volume down bond and closes the camera function starting mobile terminal, then by the magnitude of voltage of sampling resistor corresponding to side switch detection judge module collection volume down key.By default, the sampling resistor that volume down key is corresponding is in high level state, and when volume down key is pressed, the sampling resistor of its correspondence is then in low level state.
Step 240, abandon responding current blank screen gesture.
When the blank screen gesture that mobile terminal detects is not default shooting unlatching gesture, abandon carrying out response process to the gesture of user's input.Such as, the blank screen gesture inputted on terminal touch screen as user is English alphabet " S ", but the shooting unlatching gesture preset does not comprise English alphabet " S ", illustrates that user have input the blank screen gesture of mistake.Now, mobile terminal is abandoned responding current blank screen gesture, keeps holding state and does not open camera function.
Whether the voltage of the sampling resistor that step 250, judgement are preset is dragged down, and if not, then performs step 260, if so, then performs step 270.
Side switch detects judge module and is compared with the voltage threshold preset by the magnitude of voltage of the sampling resistor preset collected.If the magnitude of voltage of sampling resistor is more than or equal to voltage threshold, illustrate that side switch is in high level state, namely the side switch of mobile terminal is not pressed, then the process chip to mobile terminal returns negative acknowledge character (NAK), performs step 260 to make mobile terminal.If the magnitude of voltage of sampling resistor is less than voltage threshold, illustrate that side switch is in low level state, namely the side switch of mobile terminal is pressed, then the process chip to mobile terminal returns confirmation signal, performs step 270 to make described mobile terminal.
Step 260, determine that current blank screen gesture is invalid.
Mobile terminal, when receiving the negative acknowledge character (NAK) that side switch detection judge module returns, is determined that described gesture is invalid blank screen gesture, is not performed the operation of opening camera function.When mobile terminal is by opening gesture in the blank screen gesture detecting that user inputs on terminal touch screen for shooting, be not open camera function according to blank screen gesture immediately, but the side switch state-detection execution starting mobile terminal further confirms to detect, this testing mechanism reduces the probability of camera function by error starting of mobile terminal, and simple to operate, user operation burden can not be produced.Such as, the blank screen gesture inputted user is English alphabet " S ", and the shooting preset opens gesture when comprising English alphabet " S ", mobile terminal can't open camera function according to this blank screen gesture immediately, but inquiry side switch detects the signal that judge module sends.If now user does not press the side switch of mobile terminal or correctly do not press the side switch of specific mobile terminal, then the process chip of mobile terminal can receive the negative acknowledge character (NAK) that side switch detects judge module transmission.Now, mobile terminal determines that current blank screen gesture is invalid, does not open camera function according to described blank screen gesture.If the side switch pressing mobile terminal that now user is correct, then the process chip of mobile terminal can receive the confirmation signal that side switch detects judge module transmission.
Step 270, unlatching camera function.
Mobile terminal, when receiving the confirmation signal that side switch detection judge module returns, is determined that described gesture is effective blank screen gesture, is opened camera function according to described blank screen gesture.Such as, the blank screen gesture inputted user is English alphabet " S ", and the shooting preset opens gesture when comprising English alphabet " S ", mobile terminal can't open camera function according to this blank screen gesture immediately, but inquiry side switch detects the signal that judge module sends.If now the process chip of mobile terminal receives the confirmation signal that side switch detects judge module transmission, then illustrate that user have input the blank screen gesture of correct unlatching camera function on terminal touch screen, and the correct side switch pressing mobile terminal.Now, determine that described gesture is effective blank screen gesture, mobile terminal opens camera function according to described blank screen gesture.
