Brief description
Accompanying drawing described herein is used for providing a further understanding of the present invention, constitutes the part of the application,
The schematic description and description of the present invention is used for explaining the present invention, does not constitute the improper limit to the present invention
Fixed.In the accompanying drawings：
Fig. 1 is the flow chart of the image combining method based on dual camera according to embodiments of the present invention；
Fig. 2 is the structure chart of the image synthesizer based on dual camera according to embodiments of the present invention.
Specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing and be embodied as
Example, is described in further detail to the present invention.
According to embodiments of the invention, there is provided a kind of image combining method based on dual camera.Fig. 1 is
The flow chart of the image combining method based on dual camera according to embodiments of the present invention.
Step S110, controls black and white photographic head and colour imagery shot to shoot visual field identical image simultaneously.
Mobile terminal is provided with two photographic head of visual field identical, in other words, the angle of visual field of this two photographic head
Identical and image viewing area size is identical.Further, (Image Signal is processed by picture signal
Processing, abbreviation ISP) image scaling techniques and image stay alone pattern binning ensure two shooting
The image display area size of head is identical, and makes two to be placed in difference by technology such as Error Calculation, rectifications
The photographic head angle of visual field of position is identical.
In two photographic head of this visual field identical, including black and white photographic head and colour imagery shot.Black and white photographic head
For shooting black white image；Colour imagery shot is used for shoot coloured image.
Start the image camera function of mobile terminal, the image capture operations that detection user sends, according to detection
The image capture operations arriving, control black and white photographic head and colour imagery shot to shoot visual field identical image simultaneously.
For example：When user needs shooting image, press shutter key, shutter key at this moment can be detected and be triggered,
Control two photographic head shooting images simultaneously.
Step S120, the black white image of both full-pixel of acquisition black and white photographic head output and colour imagery shot output
The coloured image of non-both full-pixel.
Both full-pixel refers to the maximum pixel of photographic head.
By pixel setting is carried out to black and white photographic head and colour imagery shot, make the black and white that black and white photographic head exports
The pixel of image is higher than the pixel of the coloured image of colour imagery shot output, and that is, the pixel of black white image is higher than coloured silk
The pixel of color image.Further, when colour imagery shot is carried out with pixel setting, need to ensure that this colour is taken the photograph
As the coloured image of head output is undistorted.
For example：The both full-pixel of black and white photographic head and colour imagery shot is all 13M pixel, shooting image it
Afterwards, black and white photographic head exports the black white image of 13M pixel；Colour imagery shot exports the cromogram of 3M pixel
Picture.
Step S130, based on described black white image and described coloured image, synthesizes dual camera image.
Based on black white image and coloured image, synthesize the brightness using black white image, adopt coloured image
The dual camera image of color.In other words, black and white picture and coloured image are synthesized an image, should
The brightness synthesizing the image obtaining is identical with black white image, and color is identical with coloured image.
Further, the coloured image of the black white image of black and white photographic head output and colour imagery shot output is all
Bayer format；Black white image and coloured image are converted to yuv format, by the black and white of yuv format
Image and coloured image carry out synthesis process, obtain the brightness using black white image (Y), adopt cromogram
The dual camera image of the color (UV) of picture, this dual camera image is yuv format.By this YUV
The dual camera compression of images of form becomes the dual camera image of Jpeg form.
For example：The black white image of yuv format is Y1U1V1, and the coloured image of yuv format is Y2U2V2,
The dual camera image of the yuv format of synthesis is Y2U1V1, and Y2U1V1 is being compressed into Jpeg form.
The coloured image of the present embodiment is lower than the pixel of black white image, as such, it is possible to both ensured the brightness of image,
Color, undistorted, can guarantee that the dual camera image of synthesis compared to black white image and coloured image more again
Clearly, the details in image is more.
The present embodiment is clapped compared to more simultaneously than the image shooting both full-pixel coloured image and both full-pixel black white image
Take the photograph speed soon and image aggregate velocity is fast, mobile terminal power consumption is low, and Consumer's Experience is good.
Present invention also offers a kind of image synthesizer based on dual camera.Fig. 2 is real according to the present invention
Apply the image synthesizer based on dual camera of example.
This device includes:
Control module 210, for controlling black and white photographic head and colour imagery shot to shoot visual field identical figure simultaneously
Picture.
Acquisition module 220, for receiving the black white image of both full-pixel of described black and white photographic head output and described
The coloured image of the non-both full-pixel of colour imagery shot output.
The pixel of the described black white image of both full-pixel is higher than the pixel of the described coloured image of non-both full-pixel.Enter one
Step ground, the black white image of described black and white photographic head output is 13M pixel；Described colour imagery shot output
Coloured image is 3M pixel.
Synthesis module 230, for based on described black white image and described coloured image, synthesizing dual camera figure
Picture.
In one embodiment, synthesis module 230 is used for based on described black white image and described coloured image,
Synthesize brightness using described black white image, using described coloured image color dual camera image.
Further, described synthesis module 230 is specifically for turning described black white image and described coloured image respectively
It is changed to yuv format；Described black white image based on yuv format and described coloured image, synthesize and adopt
Dual camera figure with the brightness of described black white image, the yuv format of the color adopting described coloured image
Picture；The described dual camera compression of images of yuv format is become Jpeg form.
The function of the device described in the present embodiment is described in the embodiment of the method shown in Fig. 1,
Therefore not detailed part in the description of the present embodiment, may refer to the related description in previous embodiment, here is not
Repeat.
