Detailed description of the invention
Being described below in detail the embodiment of 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, the control method of embodiment of the present invention, it is used for controlling imaging device and adopts contrast formula focal modes, phase place focal modes and/or the focusing of laser focal modes, control method includes:
Rate-determining steps S10, closes contrast formula focal modes, phase place focal modes or laser focal modes according to scenario parameters.
Referring to Fig. 2, the control device 100 of embodiment of the present invention is used for controlling imaging device 200 and adopts contrast formula focal modes, phase place focal modes and/or the focusing of laser focal modes, controls device 100 and includes controlling module 10.
The control method of embodiment of the present invention can be realized by the control device 100 of embodiment of the present invention.Wherein, rate-determining steps S10 can be realized by controlling module 10.In other words, module 10 is controlled for closing contrast formula focal modes, phase place focal modes or laser focal modes according to scenario parameters.
Under normal circumstances, contrast formula focal modes changes according to the contrast of focal point picture, lens location when searching contrast is maximum.When captured picture contrast is maximum, imaging is the most clear, namely realizes focusing.Being appreciated that in contrast little, for instance in pure color scene, contrast formula focal modes is likely difficult to lens location when finding contrast maximum thus causing focusing unsuccessfully.
In phase place focusing technology, the pixel of imageing sensor is generally made up of in pairs left and right pixel.Imaging device 200 generates the data waveform of left pixel and the data waveform of right pixel respectively.When the data waveform of left pixel and the data waveform waveform of right pixel overlap, captured picture is the most clear, namely focuses successfully.Thus, imaging device 200 can calculate the moving direction of lens set in imaging device 200 and distance according to the phase meter of the data waveform of left and right pixel and then realize focusing.Phase place focusing technology generally can successfully realize focusing under ordinary ray.
But in low-light scene, the imageing sensor in imaging device 200 is likely to need to adopt higher light sensitivitys imaging, causes that the color of image is made an uproar and is likely to relatively greatly, and then has influence on the data waveform of left and right pixel.In this case, the data waveform possibility of left and right pixel cannot overlap and ultimately result in imaging device 200 be likely to be at the state moving repeatedly lens set and cannot realize focusing.In other words, phase place focal modes uses limited in some low-light scene.
Laser focusing is then the characteristic utilizing iraser centrality not easily to spread by force, emits from device by recording iraser, reflects through target surface, the time difference finally received by diastimeter again, calculate the target distance to test instrunment.This distance is the object distance in focus process, and the focometer further according to lens set calculates the concrete numerical value of the required image distance adjusted and then adjusts focusing position, it is achieved focusing.
But existing laser focusing technology is likely difficult to realization focusing in the scene that the object distance of object is bigger.On the other hand, it will be understood that in high light scene, laser focal modes is susceptible to the impact of other light.In other words, laser focal modes uses in some object distance scene farther out or some high light scene and is restricted.
Specifically, embodiment of the present invention control method and control device 100 according to scenario parameters close corresponding focal modes.Scenario parameters includes the contrast of scene, scene brightness and/or object distance.It should be noted that in an initial condition, three kinds of focal modes may be in closed mode, and will determine that corresponding focal modes remains turned-off detecting after scenario parameters meets certain condition.Such as in pure color scene, contrast is relatively low, and contrast formula focal modes is restricted, it is determined that contrast formula focal modes remained turned-off.In other words, in this scene, contrast formula focal modes is constantly in closed mode.Imaging device 200 will not adopt contrast formula focal modes that this pure color scene is focused, and is possible with phase place focal modes or laser focal modes is focused.
Being appreciated that and close corresponding focal modes and adopt other focal modes in using limited scene, imaging device 200 does not have situation about cannot focus.
So, the control method of embodiment of the present invention and control device 100 and corresponding use limited focal modes by closing according to scenario parameters, it is possible to increase Consumer's Experience.
Referring to Fig. 3, in some embodiments, scenario parameters includes the object distance of the object in scene.Step S10 includes step:
S11: judge that whether object distance is more than first threshold；And
S12: close laser focal modes when object distance is more than first threshold.
Referring to Fig. 4, in some embodiments, scenario parameters includes the object distance of the object in scene, controls module 10 and includes the first judgement submodule 101 and the first process submodule 102.
By first, step S11 in the control method of embodiment of the present invention can judge that submodule 101 realizes, step S12 can be processed submodule 102 by first and realize.In other words, first judges that submodule 101 is used for judging that whether object distance is more than first threshold.First processes submodule 102 for closing laser focal modes when object distance is more than first threshold.
Specifically, laser focal modes when object object distance farther out possibly cannot realize focusing.Such as, outside the object distance range of 1 meter, laser focal modes possibly cannot realize focusing, then be set as first threshold by 1 meter, laser focal modes is closed in the object distance scene more than 1 meter.It should be noted that the size of first threshold is relevant with the hardware performance of imaging device 200, it is possible to obtain through test of repeatedly focusing.Certainly, user can set the size of first threshold according to the use habit of oneself in user interface.
So, imaging device 200 in object distance scene farther out, can cut out and use restricted laser focal modes.
Referring to Fig. 5, in some embodiments, imaging device 200 includes laser ranging system 21, and laser ranging system 21 is used for measuring object distance and adopts laser focal modes to focus with auxiliary imaging devices 200.Step 10 further comprises the steps of:
S13: control imaging device 200 and adopt laser focal modes to focus to measure object distance by laser ranging system 21.
Referring to Fig. 6, in some embodiments, imaging device 200 includes laser ranging system 21, and laser ranging system 21 is used for measuring object distance and adopts laser focal modes to focus with auxiliary imaging devices 200, controls module 10 and includes measuring submodule 103.
Step S13 in the control method of embodiment of the present invention can be realized by measuring submodule 103.In other words, measure submodule 103 to be used for controlling imaging device 200 and adopt laser focal modes to focus to measure object distance by laser ranging system 21.
So, it is possible to measure object distance by laser ranging system 21.
Referring to Fig. 7, in some embodiments, scenario parameters includes scene brightness.Step S10 includes step:
S14: judge that whether scene brightness is less than Second Threshold after closing laser focal modes；And
S15: close phase place focal modes when scene brightness is less than Second Threshold.
Referring to Fig. 8, in some embodiments, scenario parameters includes scene brightness, controls module 10 and includes the second judgement submodule 104 and the second process submodule 105.
By second, step S14 in the control method of embodiment of the present invention can judge that submodule 104 realizes, step S15 can be processed submodule 105 by second and realize.In other words second judges that submodule 104 for judging that whether scene brightness is less than Second Threshold after closing laser focal modes.Second processes submodule 105 for closing phase place focal modes when scene brightness is less than Second Threshold.
Specifically, after closing laser focal modes, being again in low-light scene farther out in some object distance, phase place focal modes possibly cannot realize focusing simultaneously.Such as, in luminous flux low-light scene in 100 lumen ranges, phase place focal modes possibly cannot realize focusing, then 100 lumens are set as Second Threshold, phase place focal modes is closed in luminous flux is less than the low-light scene of 100 lumens.It should be noted that the size of Second Threshold is relevant with the hardware performance of imaging device 200, it is possible to obtain through test of repeatedly focusing.Certainly, user can set the size of Second Threshold according to the use habit of oneself in user interface.
So, after closing laser focal modes, it is possible to be further turned off phase place focal modes according to the size of scene brightness.
Referring to Fig. 9, in some embodiments, imaging device 200 includes imageing sensor 21.Step S10 includes step:
S16: obtain scene brightness according to light sensitivitys (ISO) value of imageing sensor 21.
Referring to Figure 10, in some embodiments, imaging device 200 includes imageing sensor 21, controls module 10 and includes obtaining submodule 106.
Step S16 in the control method of embodiment of the present invention can be realized by obtaining submodule 106.In other words obtain submodule 106 and obtain scene brightness for light sensitivitys (ISO) value according to imageing sensor 21.
So, it is possible the sensitivity value according to imageing sensor 21 and determine scene brightness.
Referring to Fig. 9, in some embodiments, step S10 includes step:
S17: close contrast focal modes when scene brightness is more than or equal to Second Threshold.
Referring to Figure 10, in some embodiments, control module 10 and include the 3rd process submodule 107.Step S17 in the control method of embodiment of the present invention can be processed submodule 107 by the 3rd and realize.In other words the 3rd process submodule 107 for closing contrast focal modes when scene brightness is more than or equal to Second Threshold.
It should be noted that when scene brightness is more than or equal to Second Threshold, it is believed that phase place focal modes is always that by focusing.Compared with contrast focal modes, phase place focal modes focusing speed is higher than the focusing speed of contrast focal modes.
So, when scene brightness is more than or equal to Second Threshold, contrast focal modes is closed, be equivalent to help user to automatically select the more quick focal modes of one, be also avoided that the use restriction being subject to the low scene of contrast simultaneously.
Referring to Figure 11, in some embodiments, scenario parameters includes scene brightness.Step S10 includes step:
S18: judge that when object distance is less than or equal to first threshold whether scene brightness is more than the 3rd threshold value；And
S19: close laser focal modes when scene brightness is more than three threshold values.
Referring to Figure 12, in some embodiments, scenario parameters includes scene brightness, and control module 10 includes the 3rd and judges submodule 108 and fourth process submodule 109.
By the 3rd, step S18 in the control method of embodiment of the present invention can judge that submodule 108 realizes, step S19 can be realized by fourth process submodule 109.In other words, the 3rd judges that submodule 108 is for judging that when object distance is less than or equal to first threshold whether scene brightness is more than the 3rd threshold value.Fourth process submodule 109 for closing laser focal modes when scene brightness is more than three threshold values.
Being appreciated that and closely focusing in scene, whether laser focal modes is restricted the brightness also needing to reference scene.Such as in some logical light quantity scene more than 1000 lumens, laser focal modes possibly cannot realize focusing.Then 1000 lumens are defined as the 3rd threshold value, passing through to measure in the scene more than 1000 lumens, laser focal modes are closed.It should be noted that the size of the 3rd threshold value is relevant with the hardware performance of imaging device 200, it is possible to obtain through test of repeatedly focusing.Certainly, user can set the size of the 3rd threshold value according to the use habit of oneself in user interface.
So, imaging device 200 in high light scene, can cut out and use restricted laser focal modes.
Referring to Figure 11, in some embodiments, step S10 includes step:
S110: close phase place focal modes and contrast focal modes when scene brightness is less than or equal to three threshold values.
Refer to Figure 12, in some embodiments, control module 10 and include the 5th process submodule 110.Step S110 in the control method of embodiment of the present invention can be processed submodule 110 by the 5th and realize.5th process submodule 110 for closing phase place focal modes and contrast focal modes when scene brightness is less than or equal to three threshold values in other words.
It should be noted that closely focusing in scene, when scene brightness meets again the condition less than or equal to the 3rd threshold value, it is believed that laser focal modes is always that by focusing simultaneously.On the other hand, in different focal modes, the focusing speed of laser focal modes is better than the focusing speed of other focal modes.At this point it is possible to close contrast formula focal modes and phase place focal modes.
So, always it is that by the scene of focusing in laser focal modes, contrast formula focal modes and phase place focal modes are closed.Be equivalent to help user to automatically select the more quick focal modes of one, thus improve the experience of user.
In some embodiments, step S10 includes step:
S111: judge that whether brightness is less than Second Threshold when scene brightness is less than or equal to three threshold values；And
S112: close phase place focal modes when scene brightness is less than Second Threshold.
In some embodiments, control module 10 to include the 4th and judge submodule 111 and the 6th process submodule 112.By the 4th, step S111 in the control method of embodiment of the present invention can judge that submodule 111 realizes, step S112 can be processed submodule 112 by the 6th and realize.
In other words, the 4th judges when scene brightness is less than or equal to three threshold values, submodule 111 is for judging that whether brightness is less than Second Threshold.6th processes submodule 112 for closing phase place focal modes when scene brightness is less than Second Threshold.
So, in some scene being again simultaneously closely the low light level, it is possible to close phase place focal modes and be able to confirm that the not use by current scene of laser focal modes is limited.
In some embodiments, scenario parameters includes scene brightness, and rate-determining steps includes:
S113: judge that whether scene brightness is less than Second Threshold；And

In other words, the 5th judges that submodule 113 is used for judging that whether scene brightness is less than Second Threshold.7th processes submodule 114 for closing phase place focal modes when scene brightness is less than Second Threshold.
So, imaging device 200 when scene brightness is less than Second Threshold, can directly cut out phase place focal modes.
In some embodiments, step S10 includes step:
S115: close laser focal modes and contrast focal modes when scene brightness is more than or equal to Second Threshold.
In some embodiments, control module 10 and include the 8th process submodule 115.Step S115 in the control method of embodiment of the present invention can be processed submodule 115 by the 8th and realize.8th process submodule 115 for closing laser focal modes and contrast focal modes when scene brightness is more than or equal to Second Threshold in other words.
So, imaging device 200 when scene brightness is more than or equal to Second Threshold, can directly cut out laser focal modes and contrast focal modes, thus decreasing follow-up judgement step.
In some embodiments, scenario parameters includes the object distance of the object in scene.Step S10 includes step:
S116: judge that whether object distance is more than first threshold after closing phase place focal modes；And
S117: close laser focal modes when object distance is more than first threshold.
In some embodiments, scenario parameters includes the object distance of the object in scene, and control module 10 includes the 6th and judges that submodule 116 and the 9th processes submodule 117.By the 6th, step S116 in the control method of embodiment of the present invention can judge that submodule 116 realizes, step S117 can be processed submodule 117 by the 9th and realize.
In other words, the 6th judges that submodule 116 for judging that whether object distance is more than first threshold after closing phase place focal modes.9th processes submodule 117 for closing laser focal modes when object distance is more than first threshold.
It is appreciated that at some low light level it is again that in the remote scene focused, phase place focal modes and laser focal modes all cannot realize focusing simultaneously.
So, it is again in the remote scene focused at some low light level simultaneously, closes and use restricted phase place focal modes and laser focal modes, it is possible to increase Consumer's Experience.
In some embodiments, scenario parameters includes scene brightness.Step S10 includes step:
S118: judge that whether scene brightness is more than the 3rd threshold value；And
S119: close laser focal modes when scene brightness is more than three threshold values.
In some embodiments, scenario parameters includes scene brightness, and control module 10 includes the 7th and judges that submodule 118 and the tenth processes submodule 119.By the 7th, step S118 in the control method of embodiment of the present invention can judge that submodule 118 realizes, step S119 can be processed submodule 119 by the tenth and realize.
In other words, the 7th judges that submodule 118 is used for judging that whether scene brightness is more than the 3rd threshold value.Tenth processes submodule 119 for closing laser focal modes when scene brightness is more than three threshold values.
So, imaging device 200 can directly judge whether to cut out laser focal modes according to scene brightness.
