First above-mentioned problem of the present invention solves like this: a kind of image sensor is provided, formed by light sensation assembly two-dimensional arrangements, described light sensation assembly comprises by long video sensing assembly and the short displacement inductive component that is used for the change of sensing projection image of time for exposure that is used to take in projection image's (promptly see through optical lens and be projected in image on the described inductor) of the time for exposure of logical partitioning; The size of described displacement inductive component is not more than described video sensing assembly.
According to image sensor provided by the invention, the blue assembly of the red assembly of monochrome (monochrome) assembly that described light sensation assembly can be photometry brightness or survey ruddiness or the green color component of survey green glow or survey blue light.In the legend, make code name monochromatic, red, green, blue video sensing assembly 1 with M, R, G, B.Make code name monochromatic, red, green, blue displacement inductive component 2 with m, r, g, b.
According to image sensor provided by the invention, no matter described video sensing assembly is monochromatic or colored (promptly by R, G, B composition), described displacement inductive component also can be monochromatic or colored.In other words, monochromatic image capturing though be to adopt monochromatic video sensing assembly, also can adopt monochrome or colored displacement inductive component.And on the other hand, colored image capturing though be to adopt colored video sensing assembly, also can adopt monochrome or colored displacement inductive component.
According to image sensor provided by the invention, described image sensor can be the image sensor of CCD or CMOS or all two-dimensional arrangements matrix forms.
Above-mentioned another problem of the present invention solves like this, and a kind of video sensing method is provided, and uses image sensor, comprises the steps:
1) the light sensation component logic is assigned as the displacement inductive component that is used to take in the video sensing assembly of projection image and is used for the change of sensing projection image;
2) between described video sensing assembly exposure period, repeatedly read the value of described displacement inductive component, as calculating projection image's delta data.
3) control according to described delta data that described image sensor moves or see through the described optical lens of control and on image sensor, keeps extremely constant greatly, thereby make filmed image more clear to reach to described projection image.
4) video sensing assembly exposure finishes, and reads the value of whole video sensing assemblies and handles.
According to video sensing method provided by the invention, described step 2) in number of times fix.For example 15 times.In other words, if the time for exposure of video sensing assembly is Δ t, the displacement inductive component read at interval that (readout interval) (annotating: read the interval=time for exposure+time for reading) is Δ t/15.Be noted that because the quantity of displacement inductive component generally is seldom, so the time for reading of displacement inductive component also is quite few.Under this situation, we can suppose that the time for exposure of displacement inductive component is probably to equal to read at interval.
According to video sensing method provided by the invention, described step 2) in number of times be with regular time as foundation.For example 1/200 second (5ms).In other words, every 1/200 second, the displacement inductive component just can be read once.

Figure 13 is a video sensing method principle schematic of the present invention.

Embodiment
At first, image sensor of the present invention is described.The present invention is the two-dimensional array that is formed by a plurality of light sensation assembly row examples, be its light sensation assembly with the difference of existing image sensor, except looking like traditionally as the video sensing assembly, wherein partly (generally being little part) light sensation assembly can be changed and be used for responding to the image that is projected in image sensor and move, and this light sensation assembly is defined as the displacement inductive component.This displacement comprises that the straight line on the plane moves, rotates and because of optical axis changes the deformation of image cause, thereby makes corresponding rectification, to avoid image blur.In the use of reality, the quantity of displacement inductive component can be lacked a lot than the quantity of video sensing assembly.Such arrangement has two benefits; 1. reduce influence to the image quality.2. the value that makes high-frequency read whole displacement inductive components becomes pratical and feasible.The displacement inductive component generally is but is not restricted to the co-ordination of large-spacing and fixes or be not distributed on the image sensor regularly.The sample frequency of displacement inductive component is more a lot of soon than video sensing assembly.So can have a little just can respond in moving being projected in image on the image sensor, thereby make suitable rectification.
The second, key of the present invention is described: the displacement inductive component.
(1) the displacement inductive component is independent of the operation of video sensing assembly.Be that the stored value of displacement inductive component is can read at any time and do not influence the video sensing assembly and continue recording image.
(2) the displacement inductive component generally is but is not restricted to the co-ordination of large-spacing and fixes or be not distributed on the image sensor regularly.Between the co-ordination at a distance of number row or column even more than the dried row or column.Generally on image sensor, each 10 row or column of co-ordination are very enough.Even if get only 1,2 row or column, also can bring into play certain effect.So the quantity of displacement inductive component only accounts for few part of whole photosensory assemblies: one of tens of part and even one of 1,000,000 parts.Influence to the image quality is very little.
(3) size of displacement inductive component can be the same or less with the video sensing assembly.Less displacement inductive component closely links up the drift that bigger displacement inductive component more can spy out image observantly.
(4) the sensitization color of displacement inductive component is not necessarily the same with video sensing assembly on every side.It both can be monochromatic, can be again colored (B forms for R, G).The advantage of using monochromatic displacement inductive component is hundred parts of ratios that reduce its quantity and account for whole inductor area.The former helps reading fast, and the latter helps the image quality.Using the advantage of colored displacement inductive component is to increase its resolution capability to color.Avoid different colours but the resolution difficulty of the picture point of same brightness and the error that causes.Fig. 1-12 has specifically showed different sizes, some image sensor examples of the displacement inductive component of different colours and video sensing assembly.
(5) the picture point value that has lacked because of the existence of displacement inductive component can be filled up or reduce with method for processing signals.If in the position of certain picture point is to be occupied jointly by displacement inductive component and video sensing assembly, through operation program or electronic circuit follow do suitable amplification according to the area magnitude proportion after, the value of this video sensing assembly gained just can be as the value of calculating this picture point.
The 3rd, operation principle of the present invention is described:
(1) because the reading frequency of displacement inductive component is high more a lot of than the reading frequency of video sensing assembly.In other words: the time for exposure of video sensing assembly than the time for exposure long number of displacement inductive component doubly to hundreds of times.Specifically, the reading frequency of displacement inductive component can be fixed in a numerical value, for example, and per second 200 times; Or regulate according to the time for exposure of image, for example, " the displacement inductive component the time for exposure=time for exposure/10 of video sensing assembly "; Again or according to the speed of the image drift velocity on the displacement inductive component and regulate reading frequency automatically, fast more image drift correspondence reading more frequently.More frequently the corresponding regulation and control more frequently of reading are corrected.
(2) as shown in figure 13, when projection image at the position change of displacement inductive component, just to make suitable adjustment, for example, moving lens system or image sensor be not so that in the video sensing assembly time for exposure, too many change takes place in the position of image sensor in projection image.Can guarantee like this to take the photograph image definition.The change that is projected in the displacement inductive component is not limited to simple displacement, also comprises complicated displacement, and as torsional displacement (angular displacement), or the influence that causes because of the change of optical axis also can correspondingly be corrected.
(3) except the data of blurring, the displacement inductive component also can be used as speed or the acceleration induction device uses.Method is that the change in displacement of utilizing continuous two width of cloth displacement inductive component data computation to go out draws the speed added value to change in displacement divided by time interval again, and the speed that speed added value and last time are calculated is added up and drawn up-to-date speed then.The method of calculating acceleration is simpler, is exactly divided by corresponding time interval the difference of two continuous speed.Be noted that the speed that calculates like this or acceleration just the time interval that when it calculates, adopted of representative every in speed or the mean value of acceleration.Except shaking because of camera the image fog that is caused, the mobile fuzzy (motion blur) because of main body fast moving in the picture causes also can be lowered.The calculating of above-mentioned blurring, speed or acceleration can be taken by the electronic circuit of microcontroller (MCU) or custom-made.Further, can also be combined into a circuit module to microcontroller exclusive disjunction circuit with image sensor.
In addition, this image sensor can be used in combination with existing camera or video camera shake-proof technology, to strengthen shockproof effect, makes image more clear.The design of this image sensor is applicable to the image sensor that all kinds of two-dimensional arrangements matrix form light sensation assemblies are formed, as image sensors such as CCD or CMOS.
The 4th, further describe the inventive method in conjunction with control program, image sensor control program of the present invention specifically as shown in figure 14, comprising:
510) photograph or shooting beginning.At this moment, the time for exposure is known.Image sensor or lens system have also been got back to the centre position, convenient later mobile regulation and control.
520) high frequency reads the value of the displacement inductive component in the image sensor;
530) compare judge to calculate secondary read between change in location (the being displacement) data of projection image;
540) further computational speed and acceleration as required;

600) picked-up of end one frame image.Image sensor or lens system are got back to the centre position awaits orders.

In the middle of image sensor legend of the present invention, even in same image sensor, the size of some video sensing assemblies can be with other video sensing assembly difference.In addition, the size of some displacement inductive components can be with other displacement inductive component difference.As the signal value of the assembly gained that will compare different sizes (make comparisons), just should suitably increase the method for the value of less assembly earlier with software or hardware with the area size.Software approach is meant its numerical value surplus big when the computing.Hardware approach is meant and adds that in image sensor suitable amplifying circuit increases signal.
