Detailed description of the invention
Describe the embodiment of embodiments of the present invention below in detail, the example of described embodiment is shown in the drawings,Wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Exemplary below by the embodiment being described with reference to the drawings, only for explaining embodiments of the present invention, and can notBe interpreted as the restriction to embodiments of the present invention.
Refer to Fig. 1, the control method of embodiment of the present invention, adopts laser focal modes pair for controlling imaging deviceBurnt. Wherein, imaging device comprises laser beam emitting device.
Control method comprises the following steps:
S10, judges whether to produce focusing triggering signal; And
S20 is controlled to as device unlatching laser beam emitting device and focuses and do not producing focusing in the time producing focusing triggering signalWhen triggering signal, be controlled to as device and close laser beam emitting device.
Refer to Fig. 2, the control device 100 of embodiment of the present invention comprises judge module 10 and control module 20. As exampleSon, the control method of embodiment of the present invention can be realized by the control device of embodiment of the present invention 100, can be applicable to electronicsDevice 1000, electronic installation 1000 can comprise control device 100 and imaging device 200. Imaging device 200 comprises laserEmitter 30.
Wherein, the step S10 of the control method of embodiment of the present invention can be realized by judge module 10, and step S20 canTo be realized by control module 20. That is to say, judge module 10 is for judging whether to produce focusing triggering signal. Control module20 for being controlled to when triggering signal as device 200 and opening that laser beam emitting device 30 is focused and do not producing producing focusingWhen focusing triggering signal, be controlled to as device 200 and close laser beam emitting device 30.
Laser focal modes is applied in electronic installation more and more widely because of its speed of focusing faster. Laser focusing is mainUtilize infrared light centrality to be difficult for by force the characteristic of diffusion, emit warp by recording infrared light from laser beam emitting deviceCross target surface reflection, the last received time difference, image-signal processor calculates the distance of target to imaging device.This distance is the object distance in focus process, then calculates image distance concrete of required adjustment according to the focometer of eyeglass moduleNumerical value and then adjustment focusing position, realize focusing. Be understandable that, laser focal modes is as the one mould of initiatively focusingFormula, in the time that user enters camera applications, laser beam emitting device can launch infrared light for finding range to complete focusing, thereforeCan produce higher power consumption.
Open electronic installation 1000 user, for example, when the camera applications of mobile phone, conventionally before focusing, do not produce startingWhen focusing triggering signal, mobile phone is conventionally in unsteady state, and now normally user will in the process of finding objectMobile phone is placed in diverse location, will ensure the stable of mobile phone in the time of focusing. When mobile phone is aligned object and mobile phone by userAfter stable state, will produce focusing triggering signal.
Detecting focusing triggering signal after, by control imaging device 200 open laser beam emitting device 30 find range withComplete focusing.
And in the process in unsteady state, can not produce focusing triggering signal at mobile phone, be now controlled to picture dressPut 200 and close laser beam emitting device 30.
In some instances, user also prepares the scenery in this scene and/or personage to take in certain scene,User opens mobile phone and chooses object by display screen as view finder unit, Laser emission dress in the process of choosing objectPut 30 in closed condition, choose object complete and prepare when focusing until user, user aims at imaging device 200Object also keeps electronic installation 1000 to remain static, and now produces focusing triggering signal, and opens Laser emissionInstall 30 pairs of objects and found range focusing.
In sum, the control method of embodiment of the present invention, control device 100 and electronic installation 1000, according to imagingWhether device 200 produces focusing triggering signal is controlled the unlatching of laser beam emitting device 30 and closes, and makes Laser emission dressPut 30 is only just to open in focus process after imaging device 200 is stable, and closes laser beam emitting device at other times30, thus power consumption effectively saved.
In some embodiments, electronic installation 1000 can be the electric terminal that mobile phone or panel computer etc. have camera function.And imaging device 200 comprises preposition and/or rearmounted camera.
Be appreciated that electronic installation 1000 includes but not limited to the example of present embodiment.
