Shooting.Originally it should be understood that in other embodiments, in the case where ensuring the enough situations of image quality, for some special scenes (examples
If reference object is single object, such as shooting certificate photo scene), it can only start corresponding camera and be shot.
Step S14 determines the major-minor relationship of long-focus camera and wide-angle camera according to the present filming scene.
It should be understood that under general scene, since the focal length of wide-angle camera is smaller, commonly used in shooting main body, based on
Camera, and long-focus camera focal length is larger, is commonly used in shooting background, is auxiliary camera.But for some specific
Scene (is preset), such as focal length photographed scene (distant view), then can be with long-focus camera for main camera, and wide-angle is taken the photograph
Picture head is auxiliary camera, preferentially to guarantee distant view clarity, sacrifices the depth of field.Simultaneously under normal circumstances, long-focus camera and
Wide-angle camera will remove shooting image all with highest clarity, in order to subsequent processing.
Step S15 judges that long-focus camera and wide-angle camera whether can when under nonspecific screening-mode
Guarantee highest clarity simultaneously.
It should be noted that the specific screening-mode is professional mode and manually selects virtualization effect mode, work as terminal

Supplemented by image captured by the auxiliary camera in major-minor relationship, by the long-focus camera and the wide-angle camera
The image of shooting is synthesized with highest clarity, to obtain lossless zoom image.
The purpose of this step is, when the image that focal length, wide-angle camera are shot can retain highest clarity, with
Highest clarity synthesizes the image that they shoot.
Step S17, based on determining major-minor relationship, based on image captured by the main camera in major-minor relationship,
Supplemented by image captured by the auxiliary camera in major-minor relationship, guarantee that the highest picture of the image of main camera shooting is clear
Degree, and the electing property of image of auxiliary camera shooting is blurred, and synthesize the main camera and auxiliary camera bat
The image taken the photograph, to obtain lossless zoom image.
The purpose of this step is, excellent when the image that focal length, wide-angle camera are shot can not retain highest clarity
First retain the highest clarity of the image of main camera (the main camera determined in step S14), and auxiliary camera is shot
Image carry out virtualization processing.
Step S18 synthesizes the image that black and white camera and colour imagery shot are shot, with one compensation figure of synthesis
Picture.
As an implementation, the concrete mode image that black and white camera and colour imagery shot are shot synthesized
It can be with are as follows:
The image shot using the black and white camera carries out details compensation, synthesis to the image of colour imagery shot shooting
Image is consistent with color image pixel.
As a kind of alternative embodiment, the tool that the image that black and white camera and colour imagery shot are shot is synthesized
Body mode can be with are as follows:
The image that colour imagery shot is shot is split as luminance signal image and carrier chrominance signal image；
The image that luminance signal image is shot with black and white camera is synthesized and (is schemed on the basis of luminance signal image when synthesis
Picture), and composograph and carrier chrominance signal image are synthesized.
Need specified, when shooting photo, colour imagery shot and black and white camera shoot image simultaneously, cancel color separation filter
The black and white camera of mirror possesses higher light-inletting quantity than colour imagery shot, therefore possesses clearer image detail, therefore utilizes
Black and white camera shooting image, to colour imagery shot shooting image carry out details compensation, can synthesis ratio common color take the photograph
As the photo that head is more clear, this clarity enhancement effect acts on particularly evident when night scene is shot.
In addition, it should be noted that, in other embodiments, if also being enabled multiple in addition to wide-angle+focal length camera
Other cameras have carried out sync pulse jamming (such as enabling 5 is taken the photograph and takes pictures), then can carry out the image that other cameras are shot
Synthesis, to synthesize a compensation image, compensates lossless zoom image with the image shot using other cameras；If removing
Other than wide-angle+focal length camera, only exists an other cameras and carried out sync pulse jamming (i.e. enabling 3, which is taken the photograph, takes pictures), then
Directly lossless zoom image is compensated with the image that the camera is shot.
Step S19 compensates the lossless zoom image using the compensation image, to obtain output image.
Specifically, include: using the specific steps that the compensation image compensates the lossless zoom image
Choosing ultra-wide angle+focal length camera composograph (i.e. lossless zoom image) is benchmark image, then utilizes black and white+coloured silk
Composograph (the i.e. compensation image) compensating color and details of color camera, are finally synthesizing an image.
It, can also be using the colour of two conventional burnt sections in other embodiments as a kind of alternative embodiment
Come black and white+colour imagery shot for substituting in the present embodiment, (equivalent focal length and arrangement can be taken the photograph camera with black and white+colour
It is consistent as head scheme), in response to this, each colour imagery shot can be made to shoot the figure of default number respectively when shooting
Picture, then utilizes image stack algorithm, and all images of synthesis colour imagery shot shooting are shone with obtaining the compensation an of high image quality
