Description
Technical field
The present invention relates generally to colour image sensing technology, relates more specifically to colour image sensing equipment and obtains number
The device of word coloured image may be used as various mobile phones, tablet computer, laptop, digital camera, DV etc.
Digital color image, video acquisition device further relate to the rendering and arrangement of the color filter element array of colour image sensing equipment
Method and image reconstructing method.
Background technology
Digital color image sensing equipment is digital camera, DV, the digital pictures such as mobile phone, tablet computer
The component of most critical in equipment, for the optical imagery of lens focus to be converted to digital color image.Colour image sensing
Equipment is collectively constituted by color filter element array and imaging sensor two parts.The function of imaging sensor (Image Sensor)
The brightness transition for being the visible light being emitted onto on sensor is electric signal, and is digitized in subsequent processing, and gray scale is generated
(black and white) image.Coloured image is generated in order to obtain the colouring information in nature, is typically employed in the surface of imaging sensor
The method for needing to cover one layer of color filter element array (Color Filter Array, CFA), by color filter element array and figure
As sensor two parts collectively constitute colour image sensing equipment.
The effect of digital image sensor is the intensity digitized of the visible light being emitted onto on sensor, generates gray scale
(black and white) image.Since a width digital picture is the pel array made of multiple pixel arrangements, correspondingly, imaging sensor is
The sensing element array being arranged in by multiple sensing elements, wherein each sensing element independently to the intensity (brightness) of the light received into
Digitized generates a pixel in digital picture.Colour image sensing equipment is to cover coloured silk on the surface of imaging sensor
Color colour filter element array, and corresponded with the sensing element array on imaging sensor so that imaging sensor can be to visible light
The light intensity (brightness) of middle different colours is digitized, and after the reconstruct of computing device, generates coloured image.Fig. 1 is shown
The structure composition schematic diagram of colour image sensing equipment, 1 indication color colour filter element array of label, label 2 indicate imaging sensor,
Imaging sensor is rearranged by sensing element, and R=Red indicate that red color filter member, G=Green indicate green color member in figure,
B=Blue indicates that blue color member, T=Transparency indicate that transparent colour filter member, colour filter member and sensing element correspond.
Color digital image equipment can be divided into three kinds according to the quantity of its internal color image sensor:(1) it is equipped with
The color digital image sensing equipment of single image sensor, the colour image sensing equipment by imaging sensor and covering thereon
Three color colour filter element array formed, the colour picture signal of acquired only one third, the signal passes through computing device
After processing, coloured image is reconstructed.Color image sensor based on single image sensor have sensor area is small, price just
Preferably, many advantages, such as manufacturing method is ripe, with the development of computing device, at present on a large scale be used for mobile phone, tablet computer,
In the various digital image devices such as digital camera, DV.(2) the color digital image equipment of multiple image sensor, such as
The external world is injected there are one polygon prism is divided in the DV of 3CCD, the DV etc. of 3CMOS, equipment inside
Visible light is divided into red, green, blue three beams, is received respectively by three independent imaging sensors (CCD or cmos image sensor),
And it is quantified as color digital image.There is no colour filter element array on 3CCD or 3CMOS color image sensors, but needs optical point
Light microscopic, bulky, manufacture is complicated, is currently only used in some medium-and-large-sized digital cameras.(3) stacked multiple image sensor
Color digital image equipment, i.e. X3 color image sensors (Japanese Sigma house journals), which uses three layer three
Color structure, i.e., the imaging sensor of three layers overlapping are respectively blue, green, red image sensor from top to bottom.It is extraneous incident
Light in blue portion first by first layer blue image sensor absorb and digitize, second layer green image sensor absorb
The red image sensor of green portion in incident light and digitlization, third layer absorbs remaining light and digitizes, to
Generate color digital image.Due to the stacking of sensor in X3 color image sensors, upper layer sensor and its circuit are to light
With certain attenuation so that the light that underlying transducer can receive is greatly decreased.In order to solve this problem, this
Class imaging sensor improves signal-to-noise ratio by increasing the area of the sensing element contained by the area and sensor of sensor, to make
It is larger to obtain entire camera volume, is generally used in the medium-and-large-sized digital camera such as slr camera.
The technical research of existing colour image sensing equipment also concentrates on the color rendering and arrangement mode of color filter member
On, such as most common color filter element array is Bayer color filter element array in color image sensor, by 2x2
RGGB (red green and green is blue) colour filter member repeated arrangement forms.
There are two types of basic generation types for color filter element array, and one is the random rows of the color filter of a variety of colors member
Row form color filter element array, and another kind is first to form a colour filter tuple by the colour filter member of different colours, then again by filtering
Color tuple repeated arrangement forms color filter element array.Above two arrangement mode has relevant patent, wherein about colour
The patent of colour filter tuple is more, and the technology of main existing color filter tuple is listed in table 1.
Table 1:The color of colour filter tuple and arrangement in color filter element array
The color filter element array of the prior art has following main feature:
1) colour filter element array is by three colors or four color colour filter member random alignments or repeated arrangement is formed in groups, colour filter tuple tool
There are 2x2,2x4,3x3, the diversified forms such as 4x4;
2) the colour filter member in color filter tuple has determining arrangement mode;
3) each colorful digital sensing equipment includes a color filter element array and an imaging sensor, and sensor
On each sensing element only acquire the signal of a color in three colors or four colors.
Although above-mentioned color filter element array adds the color digital image sensing equipment that imaging sensor is formed by image
Sensing equipment is transformed to color digital image sensing equipment from gray level image sensing equipment, but its colour filter element array filters off
2/3 light, only 1/3 light are actually reached imaging sensor and are imaged, and computing device is based on coloured silk using certain algorithm
The 1/3 obtained signal reconstruct of sampling of color image sensing equipment goes out coloured image.
Since each sensing element has inevitable stochastical sampling noise, 1/3 color samples to reduce coloured image
The signal-to-noise ratio of sensor, while independent random noise is introduced in the sampling of the color in each pixel.This problem is passing
In the medium-and-large-sized cameras such as the slr camera of system, micro- one camera, mm professional camera special, by increasing the area of sensor and correspondingly increasing
The camera lens of camera so that each sensing element obtains more light, improves the signal-to-noise ratio of imaging and is alleviated.But with
The mobile devices such as mobile phone it is universal, in order to reduce the volume and weight of coloured image image-forming module, cromogram used in mobile phone
As the area of the imaging sensor in sensing equipment is extremely limited, and pixel number is continuously improved, single pixel in imaging sensor
Area constantly reduce.To cause colour image sensing equipment in insufficient light, noise is relatively low, seriously affects cromogram
As the quality of sensing equipment acquired coloured image in illumination deficiency.And the color digital image processing in later stage is calculated with enhancing
Method (as shown in a in Fig. 8), it is difficult to inhibit the random coloration noise caused by imaging session.
The above problem can not be as traditional camera by increasing the area of imaging sensor and correspondingly increasing mirror
Head solves.The mobile-phone manufacturers such as Huawei improve the noise of image by increasing the scheme for the gray scale camera that one assists
Than to partly alleviate the above problem.For example, mobile phone of the Huawei in the models such as its P9 and P9 Plus, cruel group is in its Cool1
Etc. in the mobile phone of models, be proposed the dual camera scheme that colour imagery shot adds gray scale camera, colour imagery shot is used for obtaining
The color of object, and gray scale camera is used for obtaining the light and shade details of object.Then it is handled with color digital image and is enhanced calculation
Method (referring to the b in Fig. 8) merges coloured image and gray level image so that the coloured image taken pictures under half-light can also make
Object has abundant details.To inhibit the global noise of coloured image, the quality of coloured image is improved.But due to upper
It states in scheme, colour image sensing equipment of colour imagery shot itself does not change, therefore, in colour image sensing equipment
There is no improve for signal-to-noise ratio.Due to the noise of redgreenblue in colour image sensing equipment be it is random and mutually independent, this
The scheme of kind dual camera can enhance the details of image, but cannot still remove and derive from colour image sensing in coloured image
The noise of equipment, i.e. color noise in coloured image.
Other than the dual camera scheme of above-mentioned colour+black and white, also there is mobile phone to use dual camera scheme, such as based on double
The stereo camera of camera, the optical zoom based on dual camera.For example, the double of 7 Plus of iPhone of Apple Inc. take the photograph
As head, it is using two identical color digital image sensing equipments but the different scheme of camera lens, the i.e. camera lens of its dual camera
Wide-angle+telephoto lens, for realizing the fusion of optical zoom and digital zoom.These dual cameras are all based on existing colour and take the photograph
As the combination of head and colour imagery shot or gray scale camera, then algorithm software is used to obtain color image enhancement, optical zoom
The multiple functions such as fusion, stereoscopic vision with digital zoom, but as above-mentioned dual camera scheme, set in colour image sensing
Standby this is not innovated with it.
