Picture, and then final blending image is obtained by image co-registration.Since the field angle of wide-angle lens is big, focal length is short, it is suitble to low coverage
From taking pictures；And the field angle of telephoto lens is small, focal length is long, is suitble to take pictures at a distance, therefore, takes pictures when using dual camera fusion
When, the first image of large viewing can be obtained by first camera, and part is obtained by the second camera
Amplified second image of zoom, and then by Image Fusion by the first image and the second image co-registration, it obtains close
Like the blending image of optical zoom effect, to guarantee picture quality.
When the terminal gets the length of the self-shooting bar, and the target is calculated according to the length gauge of the self-shooting bar
Distance after, can by the way that the target range is compared with the described first default focal length and the second default focal length respectively, into
And different imaging patterns is selected according to section locating for the target range.For example, it is assumed that the target range is f, institute
Stating the first default focal length is f1, and the second default focal length is f2, f1 < f2, and f >=f1 under normal conditions.If f=f1 is controlled
The terminal is made to select the first camera imaging and export；If f1 < f < f2, the first camera shooting of terminal selection and the are controlled
Two camera fusion of imaging simultaneously export fused image；If f=f2, the terminal selection second camera imaging is controlled simultaneously
Output；If f > f2, control terminal selection second camera and be imaged, and according to the proportionate relationship of f and f2 by second
The image that camera imaging obtains exports after carrying out digital amplification.
In one embodiment, the control first camera shooting of terminal selection and second camera fusion of imaging, packet
It includes:
It controls first camera imaging and exports the first image of the reference object；
Control the second image that the second camera is imaged and exports the reference object；
Using the first image as master image, and image co-registration, shape are carried out using second image as assistant images
At the blending image of the reference object.
Specifically, the visual angle (FOV) of first camera is greater than the visual angle of the second camera, therefore, described the
That there are partial regions is Chong Die with second image for one image.Simultaneously as the focal length of first camera is less than described the
The focal length of two cameras, so that second image is relative to the picture overlay region in the first image with second figure
Domain is amplified certain multiple.It is appreciated that carrying out fusion of imaging using first camera and the second camera
When, the target object is in the overlapping region, and in the first image in addition to comprising the target object, relatively
Include wider array of background area in second image, so that wide-angle image effect be presented；And it is described in second image
Target object then relative to the target object in the first image have bigger amplification factor, thus present focal length at
As handing over.Herein on basis, by using the first image as master image, and will second image as assisting figure
Picture, and then handled by image co-registration, the blending image of similar optical zoom effect can be obtained.It is appreciated that the fusion
Image may include background area more wider array of than second image, and the data of the background area are by merging first figure
The data of the background area of picture obtain；Meanwhile the blending image also has the Zoom effect with second image approximate, institute
It states the corresponding zoom data of Zoom effect and is obtained by merging the zoom data of second image.In this way, then can be according to described
The difference of the length of self-shooting bar, i.e., the difference of the described target range control the terminal and different cameras are selected to be imaged,
To realize better imaging effect.Meanwhile the described first default focal length and the described second default coke are in the target range
It when away between, controls the terminal and selects the first camera and second camera fusion of imaging, to be realized by dual camera
The imaging effect of simulated optical zoom.
