Detailed description of the invention
Being described below in detail embodiments of the present invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of same or like function from start to finish.The embodiment described below with reference to accompanying drawing is illustrative of, and is only used for explaining embodiments of the present invention, and it is not intended that restriction to embodiments of the present invention.
Refer to Fig. 1 and Fig. 2, the control method of embodiment of the present invention, it is used for controlling imaging device and adopts the focusing of laser focal modes, wherein, imaging device includes laser beam emitting device.
Control method includes:
Step S1, it is judged that whether the light sensitivitys of the imageing sensor of imaging device is more than first threshold.
Step S2, reduces the power of laser beam emitting device when the light sensitivitys of imageing sensor of imaging device is more than first threshold.
Laser focal modes, because of its focus faster speed and focusing accuracy rate higher under half-light environment, is increasingly widely applied in electronic installation.Laser focusing mainly utilizes the characteristic that infrared light centrality not easily spreads by force, emits from laser beam emitting device by recording infrared light, reflects through target surface, and the time difference finally received, image-signal processor calculates the target distance to imaging device.This distance is the object distance in focus process, and the focometer further according to eyeglass module calculates the concrete numerical value of the required image distance adjusted and then adjusts focusing position, it is achieved focusing.It is understood that laser focal modes is as one actively focal modes, when user enters camera applications, namely laser beam emitting device can launch infrared light for range finding to complete focusing, therefore can produce higher power consumption.
In half-light environment, infrared light, because not disturbed by other ambient, remains to keep accuracy rate and the success rate of focusing, it can be considered to by the use environment of detection. electronics to control the power of laser beam emitting device thus realizing the control of power consumption.
In the embodiment of the present invention, when opening electronic installation, for instance during the camera applications of mobile phone, imaging device detects the brightness value being presently in environment automatically, when judging that this brightness value is less than preset luminance threshold, namely show that electronic installation is currently at half-light environment, and light is more weak.Now, electronic installation can improve the current light sensitivitys of imageing sensor.When the light sensitivitys of imageing sensor is more than first threshold, it is possible to control laser beam emitting device and adopt relatively low Power operation.
And when the light sensitivitys of imageing sensor is less than first threshold, infrared light is relatively big by the interference of other light, now for ensureing the success of focusing, it should the power keeping laser beam emitting device is constant.
In one example, first threshold may be configured as light sensitivitys more than 800, is the interference preventing other light when light sensitivitys is less than 800, it is necessary to keeps the operation power of laser beam emitting device, to guarantee the accuracy of focusing.And when light sensitivitys is higher than 800, it is believed that laser beam emitting device can adopt relatively low Power operation still to can ensure that the accuracy when focusing, therefore can reduce operation power, reduces power consumption.
It should be noted that the power reducing laser beam emitting device premised on the accuracy that ensure that focusing, on this basis, can should reduce the power of laser beam emitting device to a certain extent.
In sum, the control method of embodiment of the present invention judges ambient brightness according to the light sensitivitys of imageing sensor, owing to environment is more bright, environment light is more big to the interference of the infrared light that laser beam emitting device is launched, therefore, in order to improve accuracy, laser beam emitting device need to bigger Power operation.And when the light sensitivitys of imageing sensor is more than certain value (such as first threshold), may determine that environment is dark, therefore imageing sensor improves light sensitivitys, under dark situation, laser beam emitting device can adopt relatively low Power operation still to can ensure that the accuracy in focusing, therefore can reduce operation power, reduce power consumption.
Referring to Fig. 3 and Fig. 4, in some embodiments, control method is essentially identical with above-mentioned embodiment, and it is different in that, in order to ensure accuracy and the success rate of focusing, step S2 also includes:
Step S21, judges that when the light sensitivitys of imageing sensor of imaging device is more than first threshold whether object distance is less than Second Threshold.
Step S22, reduces the power of laser beam emitting device when object distance is less than Second Threshold.
Such as the explanation of above-mentioned embodiment, when that is to say light sensitivitys imageing sensor being detected under half-light environment more than first threshold, it is believed that infrared light is not disturbed by other ambient.It is contemplated that reduce the power of laser beam emitting device, and along with running the reduction of power, also will have influence on the finding range of infrared light simultaneously, and reducing along with finding range, it would be possible to influence whether success rate and the accuracy of focusing.Therefore, while the light sensitivitys of detection imageing sensor, should also be as the distance between detection imaging device and object.
Under normal circumstances, effective detecting distance of the infrared light that laser beam emitting device is launched when working with normal power is for about 1 meter, and in other words along with the reduction of laser beam emitting device power, the coverage that infrared light can record will less than 1 meter.Therefore, for ensureing when time success of focusing, it is considered to the distance that when power should detect the acquired previous frame image of imageing sensor on the basis of above-mentioned embodiment, infrared light records of running whether reducing laser beam emitting device current that is to say the distance of imaging device and object.
In one example, Second Threshold is set to 40 centimetres, it is believed that under half-light environment, when imaging device receives distance that infrared light records less than 40 centimetres, the power reducing laser beam emitting device to a certain extent will not impact when time focusing, now can control laser beam emitting device and reduce operation power.
It is understood that the action reducing laser beam emitting device power can be compared with first threshold and Second Threshold according to the relevant parameter obtaining imaging device by electronic installation, when satisfying condition, automatically reduce and run power.In the process of focusing, detection can be completed and judge.And be ensure to use when camera applications to obtain effective distance parameter, when entering camera applications, it should keep laser beam emitting device to run with peak power. every time.
And when the object distance that infrared flash ranging obtains is more than Second Threshold, infrared light also will strengthen owing to insufficient strength is subject to other interference, the success of reliability and focusing for ensureing range finding, the power that now should keep laser beam emitting device is constant.
In some embodiments, the power of laser beam emitting device includes multiple rank, and Second Threshold includes multiple.When object distance is less than a Second Threshold, reduce the power rank to correspondence of laser beam emitting device.
Such as the explanation of above-mentioned embodiment, under half-light environment, when the object distance that infrared flash ranging obtains is less than Second Threshold, reduce the power of laser beam emitting device to a certain extent, still can ensure success rate and the accuracy of focusing.
And according to the object distance recorded, multiple Second Threshold is set, the power level of each Second Threshold corresponding laser beam emitting device respectively, under the premise guaranteeing focusing, can reduce the power of laser beam emitting device to reduce power consumption to the full extent.
In one example, Second Threshold can include 40 centimetres, 30 centimetres and 20 centimetres, respectively to the corresponding power three grades of laser beam emitting device, two grades and one-level, three grades of power to laser beam emitting device corresponding to one-level are gradually lowered, its change can be linear can also be nonlinear, generally can record the relation of transmitting power and effective finding range according to experiment and be set.
In operation, persistently judging the object distance that infrared light records, whenever object distance is less than a Second Threshold, laser beam emitting device can being reduced to appropriate level, thus reducing power consumption.
In some embodiments, first threshold and Second Threshold can pass through user's input and be configured, and in other embodiments, first threshold and Second Threshold can also be that electronic installation is arranged before dispatching from the factory.System arranges and is likely the success rate of experience and the focusing ensureing most of users, relatively wide in range in threshold value setting, and for some advanced level user, can manual adjustments voluntarily, to meet demand.
Analogously, the unlatching of laser energy saver mode can be that electronic apparatus system acquiescence is opened, it is also possible to is that user setup is manually opened.Such as, when electronic installation electric power needs relatively plentifully and only to use camera applications in short-term, can without opening laser energy saver mode.
