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 only 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.
Intelligent terminal in the embodiment of the present invention includes rotating camera, and rotating camera is connected with motor, rotates with revolution.
Please refer to Fig. 1, for the present invention resets the schematic flow sheet of the first embodiment of method of rotating camera, in the present embodiment, said method comprising the steps of:
S101, when meeting pre-conditioned, starting the motor controlling described rotating camera, opening the signal projector in described rotating camera.
Wherein, described pre-conditioned can include but not limited to following at least any one:
Receive incoming call; Or
Receive the instruction exiting camera applications; Or
Receive the instruction of system reboot.
Described signal projector can be configured in rotating camera initial position one end near intelligent terminal display screen, also can be configured in the side of rotating camera near intelligent terminal both sides, not be limited in any way herein,
Intelligent terminal can be mobile phone or panel computer etc.
Signal projector can be wireless signal emission and signal can possess generator compared with highly directive, as infrared transmitting tube, laser generator etc.
S102, reads the intensity level of the signal that signal receiver receives.
Wherein, described signal projector and the described signal receiver forward when described rotating camera resets is relative.
Therefore, only need to guarantee that signal projector is relative with signal receiver energy forward when namely rotating camera reset replys initial position (the general and same direction of display screen).Such as, signal projector is arranged on when rotating camera resets near one end of intelligent terminal display screen, then signal receiver is arranged on intelligent terminal one end near rotating camera, if signal projector is arranged on the side of rotating camera near intelligent terminal both sides, then signal receiver is arranged on the position of intelligent terminal both sides near rotating camera side, when keeping rotating camera to reset, signal projector is relative with signal receiver forward.Like this, when rotating camera resets, the signal strength signal intensity that signal receiver receives is maximum.
It should be noted that, rotating camera can be arranged on the top of intelligent terminal, bottom or both sides, the embodiment of the present invention is not limited in any way, in order to user is easy to use, improve the convenience of intelligent terminal and ease for use, generally rotating camera is arranged on the upper end when top of intelligent terminal and user normally use intelligent terminal.
S103, judges whether the intensity level of described signal reaches predetermined threshold value.If reach, then perform step S104, otherwise motor will work on, and continue to rotate with rotating camera.
Alternatively, predetermined threshold value can be preset by producer when intelligent terminal dispatches from the factory and be stored in intelligent terminal, when also can be used by user, when rotating camera resets, test, then will test the value that obtains as predetermined threshold value, and along with other factors such as increase of the use duration of intelligent terminal cause the sensitivity of signal projector or signal receiver to change time, adaptive adjustment can also be carried out by user according to test result, thus guarantee the accuracy of reset.
S104, stops described motor.
When the intensity of signal reaches predetermined threshold value, then illustrate that signal projector is relative with signal receiver forward, now rotating camera returns to initial position, therefore can stop motor immediately, and the reset of rotating camera completes.
When meeting the trigger condition that rotating camera resets, rotated by motor driving rotating camera, and coordinating by signal projector and signal receiver, stop revolution when signal strength values reaches predetermined threshold value, thus guarantee that rotating camera completes reset, control simple and convenient, accuracy is high, and there will not be resets exceeds the situation of position, decreases the life consumption of motor, also save the power consumption of system, improve intelligent terminal ease for use and convenience.
It should be noted that, before step S101, namely before starter, first can also be detected the intensity level of the signal be currently received by signal receiver, if reach predetermined threshold value, then without the need to starter, thus save system power dissipation.In addition, the method for the reset rotating camera described in the present embodiment can use with other repositioning methods simultaneously, improves reset accuracy, also independently can use, not be limited in any way herein.
Please refer to Fig. 2, for the present invention resets the schematic flow sheet of the second embodiment of method of rotating camera, in the present embodiment, said method comprising the steps of:
S201, receives incoming call.
Due to user receive incoming call time, if answered near ear by intelligent terminal, conventionally, distance-sensor will control display screen and extinguish, thus avoid misoperation.If now rotating camera does not reset, cause distance-sensor cannot normal induction distance, so display screen can not extinguish.Therefore, a kind of mechanism of the rotating camera that automatically resets now is needed.In addition, if rotating camera have rotated 180 degree, then when intelligent terminal being lain in desktop, intelligent terminal may put out screen, can affect the normal use of user equally.
S202, starts the motor controlling described rotating camera, opens the infrared transmitting tube in described rotating camera.
Alternatively, infrared technology is very ripe, and power consumption is lower, and transmits and have stronger directivity, and the cost of components and parts is also very low, therefore, adopts infrared transmitting tube as signal projector in the present embodiment.
S203, reads the intensity level of the signal that infrared receiving tube receives.
Respective signal reflector, signal receiver is herein infrared receiving tube.
Wherein, described infrared transmitting tube and the described infrared receiving tube forward when described rotating camera resets is relative.
S204, judges whether the intensity level of described signal reaches predetermined threshold value.If reach, then perform step S205, otherwise motor will work on, and continue to rotate with rotating camera.
S205, stops described motor.
Please refer to Fig. 3, for the present invention resets the schematic flow sheet of the 3rd embodiment of method of rotating camera, in the present embodiment, said method comprising the steps of:
S301, receives the instruction exiting camera applications.
When user is after auto heterodyne or video calling terminate, the instruction that user exits camera applications may be received, if now rotating camera do not resetted, then may cause user in follow-up use, there is misoperation or other harmful effects, therefore need to reset to rotating camera.
S302, starts the motor controlling described rotating camera, opens the signal projector in described rotating camera.
S303, obtains the intensity parameters of the signal that described signal receiver receives.
Wherein, described signal projector and the described signal receiver forward when described rotating camera resets is relative.
S304, carries out analog-to-digital conversion to the intensity parameters of described signal, obtains the signal strength values of described signal.
Wherein, the signal received at first is analog signal, and for the ease of terminal judges and identification, needing analog-signal transitions is digital signal, thus obtains the signal strength values of signal.
S305, judges whether the intensity level of described signal reaches predetermined threshold value.
S306, stops described motor.
S307, closes described signal projector and described signal receiver.
Rotating camera is after completing reset, and motor stops operating, now all right shutdown signal reflector and signal receiver, thus the power consumption of further reduction system, extend the useful life of signal projector and signal receiver.
