Description
Technical field
The present invention relates to technical field of image processing more particularly to a kind of image processing methods based on intelligent mobile terminal
And system.
Background technology
First, with the development of mobile phone technique, smart mobile phone is widely popularized, referred to as in people's daily life
Indispensable carry-on equipment, the camera function of mobile phone are also widely used, and more and more people get used to mobile phone
Camera shoots scenery at one's side.But the Deep Canvas for being all auto-focusing, cannot achieve on slr camera of mobile phone camera
And different focus.
Secondly, some existing U.S. figure softwares, it is mostly fairly simple, it can not be to background blurring or progress focusing process.I.e.
Individual software is set to be blurred, principle does not meet optical principle yet, and effect is undesirable.In addition, software cannot achieve
Focusing and total focus processing after taking pictures.
Finally, already present two inventive techniques：Mobile phone photograph method and system (application publication number CN 103152521
A) with the method and mobile terminal (103152521 A of application publication number CN) of realization Deep Canvas in a kind of mobile terminal, this two
And technology excessively is exactly the same, is only prominent personage's main body, blurs background.In addition, patent of invention：Mobile phone photograph method and system are also
It is proposed the technology of replacement personage's background.But it is background blurring when no discussion main body is not personage in their invention.Together
When, it does not mention even more, blurs main body, the calculating of prominent background.In addition, also without discussing virtualization foreground and background, in prominent
Between scenery technology.The limitation of this two inventive techniques is larger.
Currently, on apple and Android mobile phone, there is also some application software, such as AfterFocus, but the software is
Some virtualizations are carried out on existing picture, need oneself to formulate virtualization region, if the background on the original picture is relatively fuzzyyer,
Or foreground is relatively fuzzyyer, then later processing method can not also change its clarity.Only for the more visible picture of panorama,
By some image processing methods will clearly obscure portions, to reach the anti-shooting effect of similar large aperture list.So should
Software has significant limitation.
Invention content
It is an object of the invention to：When for solution, mobile intelligent terminal handles picture in the prior art, Wu Faxu
Change foreground and background and protrude intermediate scenery, also, fuzzy picture is compared for foreground or background itself can not to change it clear
Clear the problem of spending, the present invention provide a kind of image processing method and system based on intelligent mobile terminal.
Technical scheme is as follows：
On the one hand, the present invention provides a kind of image processing method based on intelligent mobile terminal, includes the following steps：
S1：Several images for focusing different Same Scenes are obtained and store by controlling focus storehouse；
S2：Image A to be treated is shot, the articulation curve per piece image in image A and S1 is calculated；
S3：It chooses in image A and needs highlighted image block；
S4：Clarity by the multiple image obtained in articulation curve movement images A and S1 obtains described image block
The most clearly image in image A and S1；
S5：Most clearly in image, the part of part or image block except image block will be blurred；
S6：Will most clearly image and image A carry out image co-registration, obtain the image of needs and shown by display screen.
Further, step of the invention further includes：
S7：The background parts for removing image block are substituted for other backgrounds.
On the other hand, the present invention discloses a kind of image processing system based on intelligent mobile terminal, including：
Focus storehouse image collection module, the image different for obtaining several focal lengths；
Memory module, the image different for storing several focal lengths；
Image processing module, for obtaining by being carried out pair to image different with several focal lengths in memory module image A
Than, choose and fusion, and obtain the image of needs；
Display module, for showing at the different image or image of several focal lengths that focus storehouse figure acquisition module obtains
Manage the image after resume module；
Specifically, the focus heap image collection module includes：
Camera unit, for shooting image；
Control unit shoots the image storehouse of different focusing for controlling camera, and these image storehouses is sent to
Memory module or display module；
Described control unit is the software mounted on intelligent mobile terminal.
Specifically, described image processing module includes：
Target selection unit, for the highlighted image block of selection needs in image A；
Computing unit, for calculating image A and the articulation curve per piece image in the image storehouse of different focusing, and
Clarity by the multiple image obtained in articulation curve movement images A and S1 obtains described image block in image A and S1
In most clearly image；
Blur unit, for most clearly the part of part or image block except image block carried out in image it is empty
Change, and for merging the image after blurring and image A.
Specifically, described image processing module further includes replacement unit, and the background parts for that will remove image block are replaced
At other backgrounds.
After adopting the above scheme, beneficial effects of the present invention are as follows：
(1) the invention enables can arbitrarily change the depth of field, prominent foreground master when taking pictures using mobile terminal or after taking pictures
Body, or prominent background scenery, or realize that the prominent of arbitrary depth of field scenery indicates so that mobile terminal, which is taken pictures, reaches single anti-
The effect that camera is realized.Nowadays, the popularization degree of the terminals such as smart mobile phone and pad is very high, live its gradually replace camera at
The main tool for shooting living scene or scenery for people has so the invention can undoubtedly be favored by consumers in general
Vast market prospect and value.
(2) present invention is by the clarity of the multiple image obtained in articulation curve movement images A and S1, described in acquisition
Image block most clearly image in image A and S1；Finally will most clearly image is merged with image A, solve foreground or the back of the body
Scape itself compares the problem of fuzzy picture can not change its clarity.
(3) present invention can choose image the background of part to be replaced, and can be substituted for the background of user's needs,
Function is more powerful, easy to spread.

S3：It chooses in image A and needs highlighted image block.
S4：Clarity by the multiple image obtained in articulation curve movement images A and S1 obtains described image block
The most clearly image in image A and S1.
S5：Most clearly in image, the part of part or image block except image block will be blurred.
S6：Will most clearly image and image A carry out image co-registration, obtain the image of needs and shown by display screen.
S7：The background parts for removing image block are substituted for other backgrounds.
Aforesaid operations repeatedly are carried out to image A, so that it may to obtain the picture of multiple and different depth of field.
Embodiment 2
As shown in Fig. 2, the image processing system based on intelligent mobile terminal of the present embodiment, including：
Focus storehouse image collection module, the image different for obtaining several focal lengths；
Memory module, the image different for storing several focal lengths；
Image processing module, for obtaining by being carried out pair to image different with several focal lengths in memory module image A
Than, choose and fusion, and obtain the image of needs；
Display module, for showing at the different image or image of several focal lengths that focus storehouse figure acquisition module obtains
Manage the image after resume module.
Wherein, focus heap image collection module includes：
Camera unit, for shooting image, for the mobile phone in intelligent terminal, camera unit images for postposition
Head or front camera are not necessarily to external camera.
Control unit shoots the image storehouse of different focusing for controlling camera, and these image storehouses is sent to
Memory module or display module；Specifically, control unit is the software mounted on intelligent mobile terminal.
Wherein, image processing module includes：
