Coloured image is stated, the realistic colour of captured object can be preferably reduced.In addition, there there is no sensor in the electronic equipment 50
Low pass filter, it is to avoid weaken the deficiency of the reduction image resolution ratio that the generation of moire fringes is brought by low energy filter.
The converting unit 106 is used to judge that the coloured image is that first kind coloured image or Second Type are colored
Image；And when the coloured image is Second Type coloured image, the Second Type coloured image is converted into the first kind
Type coloured image.Because the image that the display of general electronic equipment can be presented is rgb format, therefore, when the electronic equipment
During the image of the 50 generation CMYK-formats, the image of the CMYK-format is then converted to rgb format by the converting unit 106
Image, so as on the electronic equipment 50 show.
In other embodiments, when first camera head 670, the second camera head 672 and the 3rd camera head
674 coloured images for being used to generate the first kind（Such as the coloured image of RGB）When, the sensor device 680 can pass through
4th camera head 676 generates the individual color channel image of white channel（That is white channel image）, the white channel figure
Each pixel has a brightness value W as in, and the synthesis unit 102 is by the white channel figure of the 4th camera head 676
As the image with first camera head 670, the second camera head 672 and the 3rd camera head 674 generation RGB is synthesized
Operation, has each monochrome value to generate each pixel（R,G,B）And brightness value（W）Coloured image, so can further carry
The definition of hi-vision.
Fig. 6 is referred to, the better embodiment of image generating method of the present invention includes：

Overlapping region.
Step S605, the monochromatic value of each pixel in the overlapping region is obtained according to each individual color channel image.Such as
When the coloured image is first kind coloured image, can be according to every in each individual color channel image acquisition overlapping region
The monochrome value R or G or B of one pixel；When the coloured image is Second Type coloured image, can be according to each individual color channel
Image obtains the monochrome value C or M or Y or K of each pixel in the overlapping region.
Step S607, according to each monochromatic value synthesis cromogram of corresponding each pixel in the overlapping region
Picture.Such as each pixel in the overlapping region according to（R,G,B）Synthesize the first kind coloured image, can also be according to institute
State each pixel in overlapping region（C,M,Y,K）Synthesize the Second Type coloured image.
Step S609, judges that the coloured image is first kind coloured image or Second Type coloured image, and
When the coloured image is Second Type coloured image, the Second Type coloured image is converted into first kind cromogram
Picture.Because the image that the display of general electronic equipment can be presented is rgb format, therefore, when electronic equipment generation is described
During the image of CMYK-format, then the image of the CMYK-format is converted to the image of rgb format, so as in the electronic equipment
Upper display.

As device obtains red channel image, green channel images and blue channel image.
Step S707, the 4th individual color channel image of the coloured image is obtained by one the 4th camera head.When described
When coloured image is first kind coloured image, can be by first camera head, the second camera head, the 3rd camera head
And the 4th camera head obtain cyan channel image, magenta channel image, yellow channels image and black channel image.At it
In his implementation method, when the coloured image is first kind coloured image, can be taken the photograph by first camera head, second
As device, the 3rd camera head and the 4th camera head obtain red channel image, green channel images, blue channel image and
Black channel image, with the definition of image after further raising synthesis.
Fig. 8 is referred to, the better embodiment of step S601 also includes：
Step S801, the first individual color channel image with the first exposure value is obtained by one first camera head.Such as to first
Individual color channel image carries out standard exposure.
Step S803, the second individual color channel image with the second exposure value is obtained by one second camera head.It is such as right
Second individual color channel image carries out reinforcement exposure.
Step S805, the 3rd individual color channel image with the 3rd exposure value is obtained by one the 3rd camera head.It is such as right
3rd individual color channel image carries out decrease exposure.In this way, can be synthesized by the individual color channel image with different exposure values
When can produce a HDR（High-Dynamic Range, HDR）Coloured image.
Step S807, the 4th individual color channel image with the 4th exposure value is obtained by one the 4th camera head.It is such as right
4th individual color channel image carries out standard exposure, so can also generate first kind coloured image or Second Type with HDR
Coloured image.
Above-mentioned video generation device and method obtain each individual color channel figure in coloured image by different camera heads
Picture, so can preferably reduce the realistic colour of captured object, it is to avoid the generation of false colour.In addition, in the electronic equipment
Sensor does not have low pass filter, it is to avoid weaken the reduction image resolution ratio that the generation of moire fringes is brought by low energy filter
Deficiency.In addition, above-mentioned video generation device and method carry out different exposures respectively by different individual color channel images, enter
And the image with HDR can be synthesized, can also further improve image by increasing the colourless camera of a black and white
