Description
Technical field
The present invention relates to communication technique field, and in particular to a kind of mobile phone photograph method, dim light or night are particularly well-suited to
The method that mobile phone is taken pictures in environment.
Background technology
With the fast development of mobile phone market, the equal only one of which camera in preposition face and rearmounted face of mobile phone gradually develops
Two cameras are set to rearmounted face, preposition face sets a camera；Or rearmounted face sets a camera, preposition face sets
Put two cameras.
The aperture of mobile phone camera is unmodifiable.In theory, if rearmounted is that a mobile phone photograph for camera is obtained
Unit light-inletting quantity than it is rearmounted be two cameras the few half of unit light-inletting quantity that obtain of mobile phone photograph.But, by reality
Shooting find that existing mobile phone taken pictures in dim light and in the case of night, it may appear that picture noise is particularly pertinent, it is overall partially
Secretly, the problem of definition extreme difference, i.e., the dual camera that the existing rearmounted face of mobile phone is set, still cannot meet under mobile phone low light environment
Effect demand of taking pictures under various scenes.
Quantity by being further added by camera of the invention, sets more than two cameras, so as to have in the rearmounted face of mobile phone
The existing mobile phone of effect is not enough because of light-inletting quantity, and the problem of the effect difference of taking pictures brought.
The content of the invention
For the shortcoming or deficiency of above-mentioned prior art, the technical problem to be solved in the present invention is to provide one kind and can solve the problem that
The mobile phone photograph method of photo-effect on mobile phone demand under mobile phone dim light or night scene environment.
In order to solve the above technical problems, the present invention has following composition：
A kind of mobile phone photograph method, including mobile phone body, also including being arranged on the camera in the rearmounted face of mobile phone body, the shooting
The setting quantity of head is two or more.
The optical property of the camera more than described two is identical.
The optical property includes focal length, the angle of visual field and relative aperture.
The resolution ratio of the camera more than described two is identical.
Camera more than described two is automatic focusing camera head.
Camera more than described two has identical frame synchronizing signal.
The index for weighing mobile phone picture useful signal is signal to noise ratio snr；The quantity of the camera is 4；Described first
The signal to noise ratio of the preview screen of taking pictures of the camera of individual unlatching is SNR1, the preview picture of taking pictures of the camera of second unlatching
The signal to noise ratio in face is SNR2, and the signal to noise ratio of the preview screen of taking pictures of the camera of the 3rd unlatching is SNR3, the described 4th
The signal to noise ratio of the preview screen of taking pictures of the camera of individual unlatching is SNR4, and SNR1 >=SNR2 >=SNR3 >=SNR4；When
During SNR ＞ SNR1, first camera is opened.
As SNR2 ＜ SNR≤SNR1, first camera and second camera are opened.
As SNR3 ＜ SNR≤SNR2, first camera, second camera and the 3rd camera are opened
Open.
As SNR4 ＜ SNR≤SNR3, first camera, second camera, the 3rd camera and
Four cameras are opened.
Compared with prior art, the present invention sets more than two cameras using rearmounted face, uses more than two phases
With optical property rear camera simultaneously take pictures, according to the varying environment that mobile phone is used, and obtain than it is rearmounted be dual camera
Or the more preferable effect of mobile phone of single camera, mobile phone shooting effect of the significantly more efficient solution under dim light or night scene environment need to
Ask；The present invention is reduced to photo environment requirement, and shooting effect is also more excellent；The present invention can greatly reduce commissioning engineer to taking the photograph
The workload of manual debugging is carried out as head.

Specific embodiment
The technique effect of design of the invention, concrete structure and generation is described further below with reference to accompanying drawing, with
It is fully understood from the purpose of the present invention, feature and effect.
As shown in Figures 1 to 4, mobile phone photograph method of the present invention, including mobile phone body 10 and it is arranged on mobile phone body 10
The camera 20 in rearmounted face, the setting quantity of the camera 20 is two or more, and the setting quantity of the camera 20 is preferred
It it is 4, the setting quantity of the camera 20 can carry out appropriate increasing or decreasing according to actual conditions.
The camera 20 is not limited to shown in above picture in the putting position at the mobile phone back side, can select arbitrary
Permutation and combination is arranged on the rearmounted face of mobile phone body 10.4 cameras 20 of rearmounted setting in the present invention, can be according to mobile phone
The varying environment for using, and obtain than it is rearmounted be the more preferable effect of the mobile phone of dual camera or single camera, significantly more efficient solution
Mobile phone shooting effect demand certainly under the conditions of dim light or night scene.
Camera 20 in the present invention is automatic focusing camera head, and its optical property is consistent with resolution ratio, the light
Performance is including focal length, the angle of visual field and relative aperture etc..The resolution ratio of 4 cameras is identical.If f-number is Fno, and
Lens focus are EFL, then Fno=EFL/D（D is the entering light aperture of mobile phone camera camera lens）.Dual camera light-inletting quantity theory is single
The twice of one camera light-inletting quantity, but be that loss of data and compression occurs image algorithm treatment is done, actual effective entering light
About 1.5-1.7 times of amount.Actual dim light is taken pictures, and effect is also and unsatisfactory, and especially noise is protruded, and definition is inadequate.
If mobile phone is taken the photograph from the consistent rear camera 20 of 4 optical parametrics, theoretical unit light-inletting quantity for single
As 4 times of head light-inletting quantity, but it is that loss of data and compression occurs image algorithm treatment is done, actual effective light-inletting quantity is about
2.5-3.1 times.So, i.e., the effect that dim light is taken pictures effectively is improved, more algorithm optimizations and effect can be done by software again
Fruit is extracted, such as rapid focus, depth of field virtualization, ultrahigh resolution, high dynamic, 3D modeling, the synthesis of various effect pictures.This hair
Bright that photo environment requirement is reduced, shooting effect is also more excellent, and can also substantially reduce commissioning engineer is carried out manually to camera
The workload of debugging.
Operation principle of the invention is as follows（As shown in Figure 5）：
