The embodiment of the present invention is applied to, described first image collecting device is used to gather the first image, described
Second image capture device is used to gather the second image.Further, first image can be to focus on
The image of color；Second image can be the image for focusing on profile, details and brightness.
Further, first image can be coloured image；Second image can be black white image.
Specifically, in embodiments of the present invention, first image capture device includes colour RGBW
Sensor, is responsible for color, can be used for gathering coloured image；Second image capture device includes black and white
Night vision sensor, is responsible for the details depth of field such as profile, details and brightness, can be used for gathering black white image.
RGBW and RGB maximum difference, in that the filter array before sensor is different.
So-called RGBW technologies are exactly to increase on original RGB red (R), green (G), blue (B) trichromatic technique
W white pixels, as the design of four colour pattern pixels.W i.e. white portion, are no optical filters
, therefore, the input quantity of light is exactly 3-4 times of other regions, significantly improves pixel in low illumination
Under light-inletting quantity, reduce noise.It is demonstrated experimentally that the first image capture device uses RGBW sensors,
High-contrast ambient brightness is enabled to lift 40%, low luminous environment noise reduction by 78%.In addition, RGBW
The W area of sensor can provide an independent gray scale induction region, and it can also be realized during low illumination
Accurate crawl to gray scale, that is, more accurately low smooth white balance can be realized.
Black and white night vision sensor, i.e. MONO sensors, are a full impregnated optical sensor, all light
All be passed directly to sensor and be captured, it takes nesting structural embedded control, advantage be possess under low light environment compared with
Degree of purity high, equipment can still be tackled calmly in the middle of the environment of insufficient light for this.
In implementing, colored RGBW sensors include colour filter filter, and black and white night vision sensor
Do not include colour filter filter.
Specifically, a photo-sensitive cell is integrated with inside each image capture device, is covered with above
Thickly dotted pixel, but each pixel is only capable of experiencing the power of light and can not experience color, so
Color filter film (i.e. colour filter filter) is added to allow the light of designated color to be radiated at picture by the top of pixel
On element, the purpose of identification color just can be reached, but entered because colour filter filter blocks most of light,
So needing to improve the sensitivity of sensor, that is, ISO under subdued light conditions, but can so bring difficulty
With the noise for avoiding.On the other hand, if the color filter film of image capture device removed, then although
It can not experience the color of light, also reform into black white image collecting device, but each pixel can
To obtain electric signal, simultaneously because light can be received by sensor completely, light-inletting quantity is more so that imaging
More clear, details is abundanter, and experiment shows, without entering for the black and white night vision sensor for carrying color filter film
Light quantity is 4 times of the light-inletting quantity of the color sensor for commonly carrying color filter film.
Therefore, in embodiments of the present invention, at least two image capture devices are employed, using coloured light point
From technology, an image capture device (i.e. the first image capture device) includes colour filter filter, is responsible for color
