The camera image sensor of unitary design.
Background technique
Now with the development of intelligent machine, mobile phone photograph is just becoming the indispensable Xiang Gongneng of people's daily life, and
Demand to effect of taking pictures is also higher and higher, has currently substituted traditional card type digital camera, however as mobile phone thickness by
Tapered small trend, also requires becoming smaller in size or controlling within an acceptable range for mobile phone camera, however opponent
The requirement of machine pixel size is gradually increased again, and the size for resulting in single pixel in this way is smaller and smaller, the light entered in this way
Also can reduce, this will result in sensitivity decline and noise becomes more, influence shooting effect, imaging sensor picture traditional at present
Element design is as shown in Figure 3.
In order to solve the problems, such as this contradiction, the technology and technique of imaging sensor be also quickly grow, however when so far
Day, Pixel Dimensions size has encountered bottleneck, then it is small if be not only extremely difficult in technique, and can also become very in effect
Difference, so present manufacturer is made up pixel by some other method and become smaller the problem of bringing, such as the coloured silk that Huawei P9 is used
Color camera (Fig. 3)+black and white camera, one is responsible for acquisition color, and one is used to acquire brightness, is synthesized by algorithm better
Effect has better light-inletting quantity, brightness and lower noise, obtains better mobile phone shooting effect with this.Problem is
The design of two cameras not only increases only cost, but also more occupies handset structure spacial influence and set to cell phone appearance
Meter.If realizing that its function can greatly reduce cost and improve the structure and appearance of optimization mobile phone using a mould group.
However, a kind of, using the colored camera image sensor for blackening white double image element unitary design, there is not been reported.
Summary of the invention
It is an object of the invention to overcome the shortage of prior art, provides and a kind of blacken white double image element integral type using colour and set
The camera image sensor of meter.

The top of color filter disc, middle part anti-dazzling screen and monochrome pixels is arranged in the micro lens.
A kind of colour blackens the method for arranging of the imaging sensor of white double-colored pixel unitary design, and the color filter disc is adopted
It with red, green, blue, is formed ' red+white ', ' green+white ', the double image element integral structure of ' blue+white '；
Each pixel is made of color and white two parts, and a part is used to perceive color signal, and a part is used to perceive
Two-part Signal averaging is got up to realize final picture signal by luminance signal.
The pixel arrangement of each unit is 2 × 4 structures, has 8 pixels；
Specially upper row is from left to right followed successively by red pixel, monochrome pixels, green pixel, monochrome pixels；Lower row is green
Color pixel, monochrome pixels, blue pixel, monochrome pixels.
Beneficial effects of the present invention:
1, the sensitivity enhancing and decrease of noise functions that camera mould group had only both been able to achieve two mould groups of colour+black and white with 1.
2, to manufacturing technique requirent with commonly singly take the photograph as mould group, substantially reduce cost, do not need complicated algorithm and after
The processing of phase synthesis.
3, the present invention is ingenious in design, novel, can conveniently obtain better photographic quality in photo-effect on mobile phone.
