Abstract

When cameras are developed from film cameras to electronic cameras, a basis is provided for intellectualization of cameras, automatic and intelligent systems are provided at the aspects of focusing and aperture adjustment, however, the time for photographing is still controlled by an operator completely, so that the problems at the aspects of the operation stability and the definition of images collected by cameras exist. The intelligent photographing system and method for obtaining stable imaging thoroughly break through traditional thinking ways in the existing image stabilizing technical field, stable images are not obtained through stabilizing of a camera lens and a charge coupled device (CCD), features of existing photographing devices, which include electronic imaging and digital storage, are used, the time for photographing is selected intelligently, and the time for picture collection and pictures are evaluated, so that clear pictures are obtained.

Description

A kind of intelligent camera system and method for stablizing imaging of obtaining

Technical field

Present photograph, picture pick-up device a lot of anti-shake technology in order to obtain stable imaging, to develop, and have the people that this technical field is referred to as surely to look like technology.The present invention has jumped out the mode that the available technology adopting the whole bag of tricks is stablized camera lens and CCD, solves the problem of stablizing imaging of obtaining with more cheap mode.

Technical background:

Traditional camera, no matter be film camera or electronic camera, its moment of taking pictures is by Artificial Control, operation fully, also just gives birth to and press shake thereupon, in conventional art, the effective settling mode of this problem is pressed shake with the tripod stabilized camera with the cable release isolation exactly.Emerging steady picture technology mainly adopts the mode of relocatable camera lens and CCD, stablizes camera lens and CCD, and its basic principle is as the shock absorber of automobile.Certainly, existing surely also have some technology exquisiter than automobile damper as technology, for example utilizes maglev mode that camera lens and CCD are floated, and utilizes voltage to moving in addition, electromagnetism carries out reverse compensation to moving to the shake that has produced, thereby obtains stable image.The realization cost of this method is higher, complex structure, fragile and volume is bigger.Also has a kind of plain mode in the prior art, time-delay is taken pictures exactly, be exactly that the user does not gather picture immediately in the moment that presses the button, but gather picture again after delaying time about 0.2 second to 1 second, so just avoided pressing shake, but this method can't solve for the shake that causes because of other factors.

Summary of the invention

After camera evolves to electronic camera from film camera, for the intellectuality of camera provides the foundation, aspect focusing, the light modulation circle automatic, intelligent system is being arranged, but aspect the opportunity of selecting to take pictures, also be from master control fully by the operator.This has also brought operational stability and the problem of the picture clarity of gathering.

The present invention has thoroughly jumped out the conventional thought of existing steady picture technical field, not to obtain stable image by stablizing camera lens and CCD, but the characteristics that existing camera installation all is electronic imaging, digitlization storage have been taken full advantage of, intelligent camera system of the present invention can intelligent evaluation at opportunity and the picture thereof of the purpose picture of gathering in the time period of taking pictures, select photo opportunity, thereby obtain clear photograph.Its selection, assessment mode be divided into gather choose the right moment before the picture and gather picture after choose the right moment,

1. choose the right moment before gathering, built-in dynamic sensitive system responds to the dynamic of camera by camera, dynamically judge module is then judged present dynamic, is reached according to dynamic trend and predict the dynamic of next moment according to the data of dynamic sensitive system, thereby determines to gather a width of cloth or a few width of cloth picture in certain stable moment.

2. gathering the back assessment chooses the right moment, stable state when the mode of selecting before the above-mentioned collection is just gathered picture according to the dynamic trend prediction camera exposure of camera, and in fact,, intelligent camera system stable from the judgement camera sends and gathers the picture instruction, begins to gather picture, gathers picture up to end, dynamically may the having greatly changed of camera in this process, the back is selected, the assessment effect is better so gather.Be that the picture acquisition system is carried out the high speed of short time earlier, gathered the picture imaging continuously, then to these images and imaging thereof constantly dynamically carry out intellectual analysis, by recalling and selecting the stable picture of constantly gathering, reach in the external effect of selecting photo opportunity again with intelligent camera system afterwards.On the angle of time shaft, exactly with the image in a period of time and dynamically be set in earlier in the high-speed cache, select wherein the most stable opportunity gathering judging of picture afterwards, and find out the picture of gathering these the most stable opportunitys.And this processing mode afterwards can be divided into two submodes, and these two kinds of submodes all need continuous imaging, the use that can be superimposed, and can produce better effect.

1) in camera installation is taken pictures imaging process continuously, utilize the state of dynamic sensitive system monitoring camera installations such as the built-in gyro of equipment, acceleration of gravity transducer simultaneously, and record its state, after the continuous imaging of a period of time is finished, compare these photographs imaging moment dynamically, select those in dynamic one the most stable or comparatively stable or several photo storage of imaging moment then, in the present invention, this dynamically to be called camera dynamic.

2) after camera installation is taken pictures imaging continuously, each photo is carried out the pixel comparison, as a whole, do not change if the consistency of the pixel of the pixel of a photo and last or one sheet photo relevant position, back is all fine, be that pixel is dynamically very little, its imaging was static, stable during that just proved and takes pictures, thereby can infer that also its imaging is clearly.Otherwise then infer unstable during its imaging, imaging is unintelligible, in the present invention, this dynamically to be called pixel dynamic.

The present invention not only can be used for the electronic camera of specialty, can also be applied in mobile phone, panel computer, personal digital assistant, etc. in the middle of many electronic equipments with camera function.

System and the implementation step of specific implementation are described below

1. the purpose of the taking pictures acquisition system of intelligent camera system is gathered the purpose of taking pictures that camera operator is sent;

2. the dynamic sensitive system monitoring camera of intelligent camera system is dynamic;

The dynamic judge module of intelligent camera system judge camera operate condition, judge moment more stably, and send director information to the picture acquisition system, guide it to gather picture;

4. the picture acquisition system of intelligent camera system is according to the director information select time section continuous acquisition picture of camera, and gives storage system with the data delivery of the picture gathered;

5. the dynamic analysis module of intelligent camera system is according to the picture of the camera multidate information assessment continuous acquisition of dynamic sensitive system generation, and camera is in the picture of more stable moment and is submitted to the man-machine interaction selective system near the picture of idea point and with picture and the camera coefficient of dynamics of assessing out, idea point near camera multidate informations such as coefficients during being chosen in the collection picture, supplies the operator with reference to selection;

6. the pixel in the picture of the picture of intelligent camera system comparison judge module comparison continuous acquisition, and be chosen in and gather picture moment imaging picture or picture and the pixel multidate information assessed out be submitted to the man-machine interaction selective system more clearly, for the operator with reference to selection;

7. the man-machine interaction selective system of intelligent camera system shows the picture of comparing the compound selection of judge module through dynamic analysis module, picture at display screen, and show that with picture its coefficient of dynamics, idea point are near the clear coefficient of coefficient, imaging, select for the operator, the man-machine interaction selective system can also be compared judge module according to picture the judged result of the subregion comparison of each picture is distinguished, pointed out in each width of cloth picture clearly and unsharp part with modes such as frame lines at screen.

8. after the operator makes a choice, the man-machine interaction selective system with selected photo storage to storage system;

The implication of relevant technologies term and content further are explained as follows among the present invention:

1. intelligent camera system,

In the present invention, the operator just provides a purpose of taking pictures of bluring relatively in time, and the opportunity of picture is gathered in concrete taking pictures, do not determined by the operator, but decided or assist operator determines opportunity of taking pictures by the built-in computer of camera, decision-making on the opportunity mode that its computer is selected to take pictures is divided into

1) decision-making before picture is gathered, intelligent camera system monitor in real time the dynamic sensitive system, and pixel dynamic, which determines gather picture constantly and preserve.

2) make a strategic decision after the picture collection, data such as the picture of intelligence camera system continuous acquisition a period of time, camera multidate information, pixel multidate information, analyze the dynamic dispatching data of dynamic sensitive system and pixel comparison then, and determine to preserve which width of cloth picture as the photo of taking pictures.This mode is more calm, also allows the personnel selection alternant way, allows the operator participate in selecting.

The built-in dynamic algorithm of judgement of intelligence camera system can be divided into,

1) camera is dynamically judged, is judged with the built-in dynamic sensitive system of camera whether camera is shaken, and judges whether it is suitable photo opportunity.

2) pixel is dynamically compared judgement, pixel with the picture correspondence position of comparing continuous acquisition, the big zone of pixel change dynamics takes place in the difference whether value of analyzing its pixel changes, changes and statistics, thereby judges whether to be suitable photo opportunity or not preserve picture and leave next step processing for.

2. dynamic sensitive system

In the present invention, the inductor of energy sensing apparatus such as all similar gyros, acceleration of gravity inductor or human action state is referred to as " dynamic sensitive system ", do not get rid of yet can use up, wireless signal detects operate condition, for example, present laser mouse can by laser imaging detect mouse dynamically, the existing reflective mark of the sort of usefulness commonly used in animation is made comes the system of human body action and the principle in the future also may be for detection of dynamically; The gloves that many transducers are housed also can detect operate condition; And system like that can be considered as the dynamic sensitive system of a complexity.

3. the purpose of taking pictures

In the present invention, intelligent camera system need obtain operator's the purpose of taking pictures, and why is referred to as the purpose of taking pictures here, is because be not to press the button camera with the sort of operator in the traditional camera to carry out simply controlling of taking pictures at once among the present invention.In the present invention, the implication of the purpose of taking pictures is not a time point, but point has comprised a time period, wherein even can comprise a plurality of reference points.For example, aim at target, be ready to take pictures from the operator, pressed the button, until the operator unclamps the button of taking pictures, even can be deferred to behind operator's release button 1 to 2 second.And concrete photo opportunity, to be camera made by intelligent camera system from the moment that CCD gathers picture, can have a plurality ofly can stablize the opportunitys of gathering picture in the time period of the purpose of taking pictures.And in the time period of this purpose of taking pictures, can also comprise a plurality of reference points, select the reference on the opportunity of collection picture as assisting intelligent camera system, comparing present electronic camera with traditional camera can have more kinds of triggering modes to obtain operator's the purpose of taking pictures and reference point thereof, exemplify several below but be not limited in following several

1) the traditional mode of pressing button,

2) mode of touch button, capacitive sensing, resistance induction, temperature infrared induction etc. both can be to lay these Sensitive Apparatuses in entity button to realize, also can lay virtual push button at touch display screen and realize.

3) speech trigger mode, the operator can adopt the mode of language to express its purpose of taking pictures to intelligence system.

4) man-machine interaction mode because the present invention relies on the operator to determine to take pictures moment accurately at full stretchly, but is selected photo opportunity automatically by the auxiliary of computer, and the suitable picture of Intelligence Selection behind the continuous acquisition picture.So confirming the mode of the purpose of taking pictures can be very light, natural, diversified mode, for example adopts the mode of man-machine interaction menu to confirm, so also is convenient to add in camera more function; For example in the ordinary course of things, for the screen of power saving camera is in resting state, when taking pictures, preparation adopt certain operation to wake up, and intelligent camera system can be thought this wake actions the initial reference point of the purpose of taking pictures, can also be again in conjunction with the dynamic sensitive system, be in stable state and just can confirm the purpose of taking pictures in case monitor out camera; Again for example in mobile phone, camera is as an application program, in a single day common people open this application namely is to prepare to take pictures, also can with moment of opening camera application program just as the initial reference point of the purpose of taking pictures, in a single day can also be again monitor out camera in conjunction with the dynamic sensitive system and be in stable state and just can confirm the purpose of taking pictures;

Traditional with one below, be positioned at the button of taking pictures above the camera the purpose of taking pictures and the reference point thereof that can produce be example, illustrate one than the time period of the long purpose of taking pictures that comprises a plurality of minor time slices and reference point wherein with reference to Fig. 1, in practice can be with a bit of time period as the purpose of taking pictures wherein, but also a greater variety of reference points can be arranged and the division methods of the purpose time period of taking pictures, this paper does not enumerate one by one.

1) t1 is that operator's finger is put on the button of taking pictures and prepares to take pictures, can be with above-mentioned touch triggering mode, and this time point can be used as the reference point of the beginning of the purpose of taking pictures.

2) the t3 person of being to use presses the time in the forward position of taking pictures button and push-button switch produce being triggered, and from then on dot system can know that operator's determination takes pictures, and infers before the t3 time point, should also have a t2 time point that is called as idea point.The idea that the decision that produces in this t2 time point operator's brain is taken pictures but hand is not pressed button as yet.System can also be reference mark is inferred this idea point t2 in conjunction with the Monitoring Data of dynamic sensitive system position with t3, so t1 can be used as the complete purpose of a taking pictures time period to t3, can certainly be just as a segment in the whole photo opporunity section.

3) t3 also is a stable moment of taking pictures to the t4 between the t5, thus t3 to can be used as between the t5 the complete purpose of a taking pictures time period, can certainly be just as a segment in the whole photo opporunity section.

Push-button switch broke away from the time point that triggers when 4) t5 was operator's release button, i.e. back edge of Chu Faing, this point can be used as the reference point of the end of the purpose of taking pictures, but only be reference point, it might not be real end point, because after the t6 time point, the stage of stable development that a moment is still arranged, so system can t5 be reference mark and in conjunction with the Monitoring Data of dynamic sensitive system, infer the t6 point, and certain time point after the t6 time point is as the end point of the purpose time period that finishes to take pictures.So a period of time before and after the t6 can be used as the complete purpose of a taking pictures time period, can certainly be just as a segment in the whole photo opporunity section.

4. collection picture

In the present invention, this concept refers to that specially the system of camera gathers the action of imaging signal from CCD or other photosensitive arrays, this vocabulary of why need not taking pictures, be because traditional taking pictures, take pictures and once just gather picture once, be corresponding, and in the present invention, once photo taking may comprise several time periods, each time period is repeatedly gathered picture again, and which width of cloth of final decision or a few width of cloth picture may be decided by the module of intelligent camera system inside as the photo of taking pictures, and may also need etc. just finally to determine after the decision-making of man-machine interactive system.So in order to prevent obscuring, just with gathering this word more specifically of picture.And the continuous acquisition picture among the present invention and general video camera difference are, general video camera is to gather 50 frames or 60 frames regularly according to the different per seconds of standard, and in the present invention, the frequency of its collection can be much higher, the speed restriction of CCD itself is about per second 20,000 frames, and the bottleneck of reality is the speed of its high-speed cache, most important difference is in the present invention, the speed of its continuous acquisition picture can be according to the data of dynamic sensitive system, or pixel multidate information etc. changes frequency acquisition in real time, more approaching and stable status is just with more intensive frequency collection.

5. operation shake,

In the present invention, the problem that intelligent camera system mainly solves is exactly the fuzzy problem of photograph that the moment camera shake of picture causes of gathering, and in the various factors that cause shake, and pressing the shake of pressing that the button of taking pictures causes is maximum shake source.Press the shake that the button of taking pictures causes, just abbreviate as and press shake.Certainly the button of taking pictures here can also comprise the virtual push button on the screen.In addition, except the button of general push type, the trigger action mode of other modes can also be arranged, for example, sideslip type button, virtual push button, sideslip type virtual push button etc., these operations can cause the shake of camera, in the present invention, it is referred to as the operation shake.

6. idea point

This is important concept among the present invention, and two main actions are arranged in the process of taking pictures, and one is camera lens stably to be aimed at want the object of taking pictures; Another is to confirm to take pictures and to press the button of taking pictures, and can disturb that the former is stable and press the button of taking pictures.The implication of the idea point among the present invention is exactly to want the object of taking pictures when the operator stably aims at camera lens, and the idea in the brains is confirmed to advance to take pictures to this object but do not pressed the time point of the button of taking pictures as yet.Certainly, this is an antinomy for traditional camera, and not pressing as yet when taking pictures button is not press shake naturally, does not also have the picture that collects.I proposed with the data that continue record dynamic sensitive system in the invention " a kind of control system and method for handheld PC equipment " of earlier submission, and recalled the mode of idea point.Though but the data that only continue record dynamic sensitive system in the present invention can find that idea point, but find the image at that idea point, also need the picture acquisition system also to carry out continuous picture collection simultaneously, and the picture of gathering need be set up corresponding relation with the data of dynamic sensitive system.Could recall the picture that idea point is gathered smoothly like this.

7. camera multidate information

In the present invention, the camera multidate information both can be the raw information that the dynamic sensitive system monitoring arrives, also can be through the information after dynamic judge module or the dynamic analysis module initial analysis processing.The raw information more complicated that the dynamic sensitive system monitoring arrives, can comprise a lot of information, for example, at three speed, acceleration that axially rotate, at three axially mobile speed, acceleration etc., its comparativity is poor, be difficult to directly go out moment the most stably with its direct assessment.The readability of gathering for the picture of camera, some is important, some then influences not quite, in Fig. 1, only listed an axial multidate information that shake is maximum, in practice can to parameters according to number respectively according to the difference of its importance be weighted then summation or average etc. comparatively complicated algorithm carry out tabulate statistics processing.Through the camera multidate information after the processing of dynamic analysis module then can be a single dynamical system numerical value or idea point near coefficient value, succinct so relatively, be convenient to choose moment the most stably or close to moment of idea point.In description of the invention, for clear description, this function is divided in the dynamic analysis module realizes, in real system, because the division of software system module can be very flexible, do not get rid of its function merging or be divided in other modules and realize, for example dynamic judge module and dynamic analysis module can be merged into a big module, even the picture acquisition system also can be combined.

8. pixel multidate information

In the present invention, the pixel multidate information refers to, in the picture of a series of continuous acquisition, by the consistency of comparing every pictures corresponding pixel on the relevant position and the information that changes thereof.Be equivalent on certain location of pixels, along the direction of time shaft, it is dynamic that pixel value changes.Certainly the pixel multidate information can also comprise the information after being further processed based on this, and for example, the pixel that can comprise certain block in the picture dynamically and statistics; Can also comprise the division based on block, the pixel that institute's zoning goes out is bigger, less zone dynamically.Certainly for convenience relatively, the pixel multidate information can also be pixel multidate information with above-mentioned complexity through certain algorithm process, become the pixel coefficient of stability of a single numerical value.In description of the invention, for clear description, this function is divided in the picture comparison judge module realizes, in real system, because the division of software system module can be very flexible, do not get rid of its function merging or be divided in other modules and realize.

9. trigger

Because native system is based on intelligence system and realizes what intelligence was taken pictures, and non-traditional mechanical system, so trigger action among the present invention might not be leaveed no choice but comprise " contact " this action as the literal meaning; Just the operator expresses the instruction that need carry out certain operation to intelligence system, as long as this expression way is to be identified by intelligence system and to accept.Its mode even can comprise sound, nictation action etc. expression way.

Description of drawings

Fig. 1 is the curve chart of the button press shake of taking pictures of a typical camera.In practical operation, the heartbeat shake that may also have the operator waits some, and other disturb shake and its stack, but do not do embodiment in this figure.Wherein, t1 is that operator's finger is put into the extremely faint shake that preparation causes when taking pictures on the button of taking pictures; T2 is that operator's brain is made the idea point of taking pictures when determining, this idea point can't singly be declared accurately from curve and breaks out, recall and could infer more exactly from the triggering of t3; The t3 person of being to use presses and takes pictures button and push-button switch is produced the time point in the forward position of triggering; Push-button switch broke away from the time point that triggers, i.e. back edge of Chu Faing when t5 was operator's release button; T4 is a steady moment between t3 and t5, is fit to gather picture; T6 is that the operator unclamps a flex point that enters again after the bounce-back of taking pictures button and causing between the stabilization sub stage, and this flex point is a steady moment, is fit to gather picture.This figure is the curve synoptic diagram of pressing shake of the common camera of button on camera of taking pictures, if button in other positions, its shake axially and mode understand different; Its jitter curve also can be different in the time of some individuals with disabilities's operation, to these special circumstances, the intelligence camera system can have the time point of actual electrical triggering signal to carry out intelligent self-learning as the reference basic point with t1, t3, t5 etc., adapt to these special jitter curve, give unnecessary details no longer one by one at this.

Fig. 2 is a schematic diagram that comprises the functional module of intelligent camera system.In practice, this intelligent camera system also needs to carry out alternately with other system, for example need with camera in autofocus system, auto iris system etc. carry out information interchange, even will be with it as prerequisite, and interactive mode also has the different modes of plurality of optional, but in this figure these and other system reciprocal process is not done embodiment.The functions of modules dividing mode of this figure is to divide according to the mode of the easiest understanding, in the middle of the system of reality, the function of module is divided and name can be very flexible, several modules wherein can be merged, and also a module can be split as several modules.

Embodiment

Embodiment 1

The steady picture technology that the camera that embeds in present electronic camera or the mobile phone adopts is put forth effort in the moment of imaging and is stablized camera lens and CCD, thereby obtains imaging clearly.The present invention has then adopted mode off the beaten track, intelligence judge module on opportunity of the present invention then can be after the operator takes pictures purpose, according to the testing result of dynamic sensitive system, assist the operator to select to take pictures, gather the opportunity an of the best picture, the avoidance operation shake.The decision-making purpose of namely taking pictures of macroscopic view time period is just made in operator's operation, and concrete collection is then decided by intelligence judge module on opportunity constantly.Below be detailed description,

1. at first, need be in existing electronic camera dynamic sensitive system such as built-in gyro, acceleration of gravity inductor, be used for the dynamic of continuous monitoring camera itself.Because the system consumption of dynamic sensitive system is very little, so both can having waited the operator to send the purpose of taking pictures, native system just began later on to monitor the dynamic of camera, also can wait the purpose of taking pictures, and it is dynamic to continue to monitor camera for a long time.Particularly with the signal of dynamic sensitive system as the control screen in the middle of the control system of cursor, the dynamic sensitive system is in running status for a long time, under the situation of this shared dynamic sensitive system, intelligent camera system only needs to call the camera multidate information in needs and gets final product.

2. the purpose of taking pictures acquisition system is obtained operator's the purpose of taking pictures, and why is referred to as the purpose of taking pictures here, is not press the button simply directly controlling that camera takes pictures at once because among the present invention be with the sort of operator in the traditional camera.In the present invention, the purpose of taking pictures refers to that the operator has aimed at target, finishes time period of taking pictures from being ready to take pictures to, and concrete photo opportunity, to be camera made by intelligent camera system from the moment that CCD gathers picture.In the time period of the purpose of taking pictures, a plurality of reference points can also be arranged, can push away or determine to gather to pusher the moment of picture with these reference points as basic point forward.Comparing present electronic camera with traditional camera can have more kinds of modes to obtain operator's the purpose of taking pictures, exemplify several below but be not limited in following several,

1) the traditional mode of pressing button.

2) mode of touch button, capacitive sensing, resistance induction, temperature infrared induction etc., both can be to lay these Sensitive Apparatuses in entity button to realize, and also can lay virtual push button at touch display screen and realize that the operator expresses its purpose of taking pictures to intelligence system.

3) speech trigger mode, the operator can adopt the mode of voice to express its purpose of taking pictures to intelligence system.

4) its purpose of taking pictures of expression such as gesture, body gesture.

5) man-machine interaction mode because the present invention relies on the operator to determine to take pictures moment accurately at full stretchly, but is selected photo opportunity automatically by the auxiliary of computer, and the suitable picture of Intelligence Selection behind the continuous acquisition picture.So confirming the mode of the purpose of taking pictures can be very light, natural, diversified mode, for example adopts the mode of man-machine interaction menu to confirm, so also is convenient to add in camera more function.

3. dynamic judge module selects to gather the moment of picture according to the camera multidate information, Fig. 1 is the jitter curve figure of button when the camera of top-right normal arrangement is being taken pictures that takes pictures, this paper illustrates several its judgment modes of possible time point based on this, but be not limited in following several

1) button of taking pictures in this example not only has the conventional func of the triggering of pressing, also possess simultaneously on the button and touch the function that triggers, its basic principle as touch-screen or the touch pad of notebook computer, this function is as the part of the system of the purpose of taking pictures of obtaining the operator.When operator's finger is placed on the button, the purpose of the taking pictures judge module of intelligence camera system just confirms that the operator prepares will begin to have taken pictures, certainly this button just can be a virtual push button on the touch-screen in the cell-phone function of mobile phone and panel computer, this time point is exactly the t1 in Fig. 1, in the t2 of Fig. 1 time point person's of being to use brain, make the resolution of taking pictures, but pointed the time point of not making push action as yet or just having begun to make push action.The built-in dynamic sensitive system of camera can detect at t1 and arrive the dynamically steady relatively of this time period camera of t2, can be as the time point of gathering picture, certainly other factors, particularly slr camera that also will consider camera in practical operation also have other indispensable factors of taking a picture such as aperture, focal length adjustment.In the present invention, operator even can not need firmly to press entity button and confirm to have taken pictures, as long as above-mentioned factor all possesses, the intelligence judge module of taking pictures just begins to gather automatically picture, can also follow simultaneously and send shutter sound that electronic virtual draws up as feedback.The benefit of this mode is exactly can not only avoid pressing the shake that button causes, even connects because the slight jitter of the arm that heartbeat causes can shield.Shortcoming is exactly that the operator who gets used to traditional camera lacks the pleasant sensation of controlling machine, and particularly some is not well concerning those control mad people a bit.

2) based on a last example, the actual idea point of operator is t2, in order to allow the time point of the picture gathered close to operator's idea point, when pressing the button of taking pictures, the built-in dynamic sensitive system of camera, the operator detects camera when beginning the trend of downward acceleration is arranged, be exactly after t2, close to moment of t2 time point as the time point of gathering picture, at this time shake is still mild relatively, so photograph is also clear relatively.Simultaneously also solved the 1st) lack the shortcoming of controlling pleasant sensation in the individual example.

3) from the t3 of Fig. 1 to t5 during this period of time, be the triggering period of electronic button, t3 wherein is the button circuit closure, is equivalent to the forward position of electric current, and t5 is that circuit disconnects, and is equivalent to the back edge of electric current.General electronic camera utilizes t3 forward position triggering constantly as the signal of triggering collection picture, in the present invention can be with the signal of the t3 moment as operator's the purpose of taking pictures, but do not gather picture at once, but continue to monitor the data of dynamic sensitive system, wait for stage of stable development moment of a flex point, shown in the t4 time point of Fig. 1, the tangent line of its jitter curve almost is level, this is equivalent to extremely of short duration section quiescent time, gather picture constantly so can be chosen in t4, and the concrete moment of this time point is to carry out roughly prediction according to the variation tendency of the jitter curve from t3 to the t4 time period and acceleration thereof, thus at t4 this to gather picture constantly also be a desirable selection.And this time point is gathered the use habit that picture relatively meets the legacy user.

4) behind operator's release button, camera has a upwards process of bounce-back, can recover mild then, and this flex point shown in the t6 moment among Fig. 1 can be detected, and also can predict by the variation tendency of jitter curve by dynamic sensor-based system.So this time point also can be used as the time point of gathering picture.

5) stage of stable development after the t6 time point, intelligent camera system also can determine to gather picture according to the data of dynamic sensitive system.

6) had traditional floating lense and CCD at one, even adopt voltage or mechanical system to carry out in the system of jitter compensation, the prediction of its shake and calculating more complicated, because the camera multidate information not only comprise the phase machine frame dynamically also to consider camera lens dynamically, at that time jitter amplitude of the performance curve, camera that needs its anti-jitter of COMPREHENSIVE CALCULATING, etc. factor.Certainly, if the system that dynamic sensitive system such as gyro and Lens CCD etc. are floated binds together, then its camera that calculates dynamically is exactly the dynamic of the system of floating, rather than the phase machine frame is dynamic, so just can avoid this contradiction.Certainly, also can on the fuselage of the system of floating and camera, respectively put a cover dynamic sensitive system, can not only measure like this they separately dynamically, can also carry out further more complicated measurement, calculating and prediction according to both differences.

4. the picture acquisition system can be gathered picture according to the optional time point of director information any one in above-mentioned steps of dynamic judge module, also can gather a width of cloth picture or several pictures of continuous acquisition at each time point, select a width of cloth or a few width of cloth and storage for the user, like this user's sensation of controlling more being arranged and deciding.Why being referred to as director information rather than instruction, is because based on the flexibility of intelligence system, and the picture acquisition system is with dynamically the division of labor of judge module can be very flexible, can include but are not limited to following several,

1) dynamically judge module decides the opportunity of gathering picture, when dynamic judge module is judged stable moment, just sends the instruction of gathering picture to the picture acquisition system, and the picture acquisition system is complete passive fill order then.

2) dynamically judge module is issued the picture acquisition system with all multidate informations, is decided the opportunity of gathering picture by the picture acquisition system.

Issue the picture acquisition system as a reference when 3) dynamically judge module has the information of same of guide effect with all multidate informations and stable moment of judging thereof etc., the picture acquisition system then considers to judge the opportunity of gathering picture according to the informix of dynamic judge module and other modules, and the information of other modules recited above can be the image comparison judge module processing gained information described in the embodiment 3.

5. the picture acquisition system is gathered after the width of cloth picture, both these pictures also can be left in it in high-speed cache earlier, and is submitted to man-machine interactive system in Nonvolatile memory system as formal photo storage.

6. man-machine interaction selective system shows alternative picture at display screen, after the operator makes a choice, the man-machine interaction selective system can be with selected photo storage to Nonvolatile memory system, its storage format can be traditional digital picture form, it also can be the distinctive picture format that comprises the camera multidate information of the present invention, can certainly be the form that has comprised the camera multidate information of the continuous picture of several width of cloth and correspondence thereof, such form be convenient to post-production.

The specific implementation step

A kind of by the auxiliary intelligent photographic method that determines photo opportunity of built-in computer, it is characterized in that intelligent camera system adopts following steps

1) purpose of the taking pictures acquisition system of intelligent camera system is gathered the purpose of taking pictures that camera operator is sent;

Embodiment 2

Though the mode of embodiment 1 is effective, but it is perfect not enough, when dynamic judge module is analyzed the camera multidate information, and conclusion reinforms the collection of picture acquisition system for after stable, when the electronic shutter that waits the picture acquisition system collection that exposes again, at this moment camera dynamically may change, can only look to enough lacking from monitoring the dynamic time to the collection picture, and the dynamic variation of camera itself is very little, so need to improve.Present embodiment is exactly in the continuous acquisition picture, record the camera multidate information simultaneously, be about to the image in a period of time and dynamically be set in the high-speed cache earlier, select wherein the most stable opportunity in the judgement afterwards of gathering picture, and find out the picture of gathering these the most stable opportunitys, it below is detailed description

2. the purpose of the taking pictures acquisition system of intelligent photographic system is obtained operator's the purpose of taking pictures, and its concrete mode of obtaining is similar to Example 1.

3. the picture acquisition system of intelligent photographic system can determine to be temporarily stored in the high-speed cache at section continuous acquisition picture sometime according to the information of the purpose acquisition system of taking pictures.Certainly as optional mode, also can adopt the mode of similar embodiment 1, allow dynamic judge module or picture acquisition system select the time period of continuous acquisition picture according to the optimization of camera multidate information.Traditional electronic camera when taking a picture, just gather a width of cloth picture in the moment of pressing the button of taking pictures, and this action of pressing the button of taking pictures can cause pressing shake, and this presses shake and can cause bluring of picture.And adopted continuous acquisition picture of the present invention mode after, not only can avoid in time pressing the shake moment, can also avoid the shake that other factors cause.Its thinking is as aiming at a target running fire with machine gun, the bullet hit home always one, certainly playing machine gun, need not to determine the end be which bullet has been hit target, and the present invention after continuous acquisition, also need which width of cloth of intelligent decision or a few width of cloth picture be clearly, more near the take pictures picture of idea point of operator.Realize that this target mode also needs to solve following two problems,

1) continuous acquisition how quickly,

The electronic shutter technology of present electronic camera provides the foundation for the high-speed and continuous pictures taken, not only can reach the speed of 50～60 frame per seconds of general video camera, even might reach the above speed of 10000 frame per seconds.But existing storage mode is to exist in the flash memory, provide the significantly speed of high definition picture of continuous storage but existing Nonvolatile memory system is the storage speed of micro harddisk or flash memory to be nowhere near, so can adopt jumbo RAM to carry out fast cache, wait to select to determine to store in the flash memory again behind a few width of cloth pictures, the price of RAM is also supported such hardware structure now, certainly the speed of not getting rid of non-compression storage system in the future improves greatly, can directly use it as high-speed cache.But the high-speed and continuous collection can bring serious problems, be exactly moment collection tens even hundreds of width of cloth picture, it obviously is unpractical coming identification selection by human eye fully, and dynamic analysis module provided by the invention, picture comparison judge module has just solved the problem of this identification selection

2) selection of acquisition time section

A) as can be seen from Figure 1, the t1 time point is that finger touch is taken pictures moment of button, and slight shake is arranged, and the t2 time point person of being to use determines the idea point of taking pictures to begin to press the button of taking pictures after this.All more stable during this period of time from t1 to t2, can be used as the time period interval of gathering picture, wherein the t2 point is operator's idea point, match operation person's demand and will, so be best acquisition time section during this period of time from t1 to t2, the judgement of this time point of t2 is fuzzyyer certainly, so, end point can be fixed on t3, namely button is pressed the forward position of triggering, recalls the operation of idea point t2 more afterwards;

B) from the t3 point to the flex point t4 that a shake is arranged the t5 point, the tangent line of its jitter curve almost is level, this is equivalent to an extremely of short duration quiescent time, and traditional camera is all from the fast exposure gate of t3 point beginning or gather picture.So to continuous acquisition picture between the t5, or select wherein the mildest a period of time to gather picture according to the data of dynamic sensitive system at t3, also can be used as a kind of selection.

C) after t6, enter the mild phase, can consider that also a period of time is as the continuous acquisition time period after t6.

D) certain, also can be with certain time point after from t1 to t6, a long time is as the acquisition time section like this.

4. in the picture acquisition system continuous acquisition picture of intelligent photographic system, the dynamic sensitive system utilizes the dynamic of built-in dynamic sensitive system monitoring cameras such as gyroscope, and the camera multidate information that monitors delivered to cache systems, and camera multidate information and the picture that collects set up corresponding relation, in order to distinguish the Different Dynamic when gathering every width of cloth picture.The method of setting up corresponding relation has a variety of, includes but are not limited to following several mode,

1) intelligent photographic system adopts special picture file storage format, its data format not only comprises the picture Pixel Information, also comprise the camera multidate information that the dynamic sensitive system when gathering this picture monitors, this camera multidate information can not only comprise fast exposure gate, gather picture that moment data constantly, even can also comprise the camera multidate information of a period of time before and after this is constantly, so that ex-post analysis.

2) intelligent photographic system adopts special picture file storage format, and its data format not only comprises the picture Pixel Information, also comprise gather this picture the time time mark; Set up independently camera multidate information storage file simultaneously, its data format not only comprises the camera multidate information, also comprise detect the respective camera multidate information the time time mark.So just can utilize both time marks to set up both corresponding relations.

3) intelligent photographic system adopts special picture file storage format, its data format not only comprises the picture Pixel Information, also comprises sequence number, and each picture is corresponding with at least one sequence number, its sequence number both may reside in the file, also can be with the filename of sequence number as storage file; Set up independently camera multidate information storage file simultaneously, the camera multidate information is also corresponding with a series of sequence number respectively hereof; So just can utilize both sequence numbers to set up both corresponding relations.

4) in conjunction with the advantage of above-mentioned several modes, the information of each picture that the intelligence photographic system collected with each time period of a big file recording occurring continuously once photo taking, in proper order, time mark, reach the camera multidate information, utilize file format itself to set up every width of cloth picture and the corresponding relation of gathering camera multidate information at that time, be similar to form, the data of database frame mode is exactly one of ready-made available mode.Can be Intelligence Selection control for the moment of gathering picture wherein, then can be continuous recording for the camera multidate information.Be convenient to further intellectual analysis, selection like this.

5. the dynamic analysis module of intelligent photographic system can be compared the camera multidate information of the dynamic sensitive system that notes in the continuous acquisition picture, and its picture of dynamically gathering close to static the time will be the most clearly.Above-mentioned dynamic evaluation can be divided into four kinds at least,

1) first finishes when a pictures collection, and camera multidate information is constantly judged, and to select be to keep or abandon according to gathering at it in real time immediately;

2) it two is after a series of continuous picture collections are finished, concentrate again and judge and select, the benefit of doing like this is to carry out compound selection together in conjunction with the selection mode that the embodiment 3 described picture pixels of back are compared, and can also adopt man-machine interactive system to carry out secondary by the operator again and select.

3) it three is in the time period of whole continuous acquisition picture, all carries out dynamic evaluation in real time, and adjusts the frequency density of gathering picture in real time accordingly, and dynamically stable, the frequency of gathering picture is more high.

4) in conjunction with top three kinds of modes, adopt first kind of mode to carry out comparatively loose Preliminary screening earlier, the picture by Preliminary screening adopts in second mode to concentrate again and selects, and can carry out compound screening with other modes.

Certainly, moment collection tens even hundreds of width of cloth picture, it obviously is unpractical coming identification selection by operator's human eye fully, can be by dynamic analysis module analysis camera multidate information, select to shake a minimum pictures, also can select several, directly as formal photo storage, or be submitted to the man-machine interaction selective system, be presented on the screen, selected by the operator, and can be on every width of cloth picture when providing the operator to select or its periphery list the camera coefficient of dynamics, this coefficient is by handling the succinct relatively understandable dynamic data of embodiment camera that the camera multidate information draws, its expression-form both can be digital form, also can be other forms of, for example use the length of colour bar, or mode such as color is represented.

6. as shown in Figure 1, the dynamic analysis module can also be analyzed according to the performance graph during taking pictures, be that reference mark is carried out backstepping, recalled with t3, find out a t3 point steady moment t2 before, Here it is close to operator's idea point of idea of taking pictures, and find out a width of cloth or a few width of cloth picture gathered at this idea point and open photo as final take.Certainly, so-called idea point is present in operator's brain, it is not a definite point for system of the present invention, but this module is inferred out, so this module also can be listed several close to the picture of idea point, and to its assessment near coefficient, these several photos and assessment coefficient thereof are submitted to the man-machine interaction selective system in the lump and are carried out secondary by the operator and select the most at last, and its mode that shows coefficient also can be various ways.

7. if the setting of intelligent camera system is to allow the dynamic analysis module filter out several pictures, carry out postsearch screening by its man-machine interactive system again, then man-machine interaction selective system shows the picture that several are selected through the dynamic analysis module at display screen, and shows that its coefficient of dynamics and idea point are near coefficient.After the operator makes a choice, the man-machine interaction selective system with selected photo storage to storage system, its storage format can be traditional digital picture form, it also can be the distinctive picture format that comprises the camera multidate information of the present invention, can certainly be the form that has comprised the camera multidate information of the continuous picture of several width of cloth and correspondence thereof, such form be convenient to post-production.The operator is by the setting of man-machine interactive system, can also revise the internal algorithm of dynamic analysis module, for example revised the opportunity of idea point forward or backward, even man-machine interactive system can also be by the each picture of selecting of operator and corresponding time point thereof, sum up rule and carry out intelligent self-learning, revise algorithm and correction value that the idea point is recalled automatically.

The specific implementation step

A kind of by the auxiliary intelligent photographic method that determines photo opportunity of built-in computer, it is characterized in that intelligent camera system adopts following steps,

2) the dynamic sensitive system monitoring camera of intelligent camera system is dynamic;

3) the dynamic judge module of intelligent photographic system or picture acquisition system are selected time period of continuous acquisition picture according to the camera multidate information, the picture acquisition system at this moment between section continuous acquisition picture, and be submitted to storage system,

4) picture gathered of the storage system of intelligent camera system storage picture acquisition system, and the camera multidate information that produces of the dynamic sensitive system of camera;

5) the dynamic analysis module of intelligent camera system is according to the picture of the camera multidate information assessment continuous acquisition of dynamic sensitive system generation, and be chosen in and gather camera during the picture and be in the picture of more stable moment or the coefficient of stability of picture and the picture assessed out is submitted to the man-machine interaction selective system, for the operator with reference to, select.

6) the man-machine interaction selective system of intelligent camera system shows the picture that several are selected through the dynamic analysis module at display screen, and shows that its coefficient of dynamics and idea point are near coefficient.After the operator made a choice, the man-machine interaction selective system was submitted to storage system with selected photo;

Technical advantage

Because present embodiment has the function of recalling idea point, has special advantages aspect splendid moment that candid photograph is difficult to predict, for example in competitive sports, senior sports photography reporter often has extremely strong anticipation ability, because from you see, to judge this be an excellent picture, again to press the button of taking pictures, camera shutter action with hand, this a series of action needs certain hour, general new hand often sink into visible candid photograph less than predicament.And with the mode of recalling idea point t2 of present embodiment among the present invention, can finish candid photograph easily.

Embodiment 3

Though the mode of embodiment 1 and embodiment 2 is effective, but perfect not enough, mainly contain two problems, first problem is, above-mentioned two embodiment select photo opportunity intelligently by intelligent camera system, and it is smudgy to avoid, eliminate the picture that operator's shake causes really effectively.But the picture that action caused is smudgy can't eliminate for rocking of the object of being taken pictures etc., in conventional art, the mode that addresses this problem has two, the first is by the searching of the operator's anxiety of taking pictures and catch object static moment, and second it be by being shown a static attitude by the photographer.Second problem is, if the operator follows the object of a movement to clap, then use the mode of above-mentioned two embodiment, the intelligence camera system may be faced with and be difficult to find suitable acquisition time section or gather the problem that picture does not meet operator's purpose opportunity, because among operator's camera is in dynamically all the time.Present embodiment is exactly in order to solve the solution of above-mentioned two problems, to find out automatically and catch by the opportunity of photographer's stable moment with intelligent camera system, simultaneously, the mode of present embodiment also can effectively be filtered and screen because the picture that the shake of camera itself causes is fuzzy.Be described in detail as follows.

1. the purpose of the taking pictures acquisition system of intelligent camera system is obtained operator's the purpose of taking pictures, and its concrete mode of obtaining is similar to Example 1.

2. the picture acquisition system of intelligent camera system determines to be temporarily stored in the high-speed cache at section continuous acquisition picture sometime according to the information of the purpose acquisition system of taking pictures., and record time mark or the sequence number of the collection of its correspondence simultaneously.Picture can be very flexible with the corresponded manner of corresponding time mark, sequence number, and is similar with the corresponded manner of picture among the embodiment 2 and camera multidate information, repeats no more.

3. the picture of intelligent camera system comparison judge module carries out the self-consistentency that each picture was compared and added up to pixel to each photo, as a whole, if the consistency of the pixel of the pixel of a photo and last or one sheet photo relevant position, back is fine, its imaging was static, stable during that just proved and takes pictures, thereby can infer that also its imaging is clearly, otherwise then infer unstable during its imaging, imaging is unintelligible, in the present invention these information is referred to as the pixel multidate information.Its pixel alignment algorithm can have following several but be not limited only to following several,

1) the most basic individual element, line by line or by the row contrast.This be the most stupid also be the most basic mode.So also the comparison result of each pixel can be prompted to the operator with modes such as flickers, but the result who shows like this can be more numerous and diverse, the operator is difficult to identification, can only identify judgement for the computer of intelligent camera system.

2) comparison of pixel at interval, both can be that continuous two of being close to of comparison, three pictures are compared mutually, also can be to compare mutually behind several pictures at interval, or the comprehensive comparison mode that combines of several modes, because the comparison of adjacent picture can only be calculated the readability of picture itself, the continuous integrated comparison then can be calculated variation tendency, even according to the next variation constantly of variation tendency prediction.Its algorithm more complicated is not given unnecessary details at this, but its external effect is just as among the embodiment 1, estimate next moment dynamic class seemingly with former and current camera multidate information and variation tendency thereof, and the two can be used for selecting to gather the opportunity of picture or adjusting the frequency of gathering picture in real time.

3) piecemeal progressively contrasts, and is about to picture and is divided into a plurality of picture blocks, compares with regard to the consistency of the respective pixel of each pixel of this block and front and back picture respective block then and add up, and can make prompting to one or several block of pixel variation maximum wherein.A Fu Dai benefit is can not only identify because the shake that camera shake causes can also identify the picture that causes owing to actions such as rocking of the object oneself of being taken pictures and blur like this, for example blinks, shakes the head etc.Like this, when the man-machine interactive system of camera when display screen is listed one or several picture that collects, can not only give the readability of every photo of user prompt, can also make prompting to unsharp block, for example in many people's group photos, the operator who takes pictures is difficult to identify at once wherein someone's nictation or shakes and first-classly causes the local unsharp situation of photograph, and adopts the intelligent camera system of the manner can identify unsharp part at once and make prompting with modes such as frame line, flickers to the operator that takes pictures.

4) adopt special-purpose hardware alignment algorithm, or compare with existing video compression chip, its basis of the compression algorithm of existing MPEG4 also is the pixel of frame before and after the contrast, data after its compression are just less if this frame is little with the previous frame difference, if it is just bigger to change data big then after the compression.So can utilize the auxiliary pixel of carrying out of existing hard compression chip fully compares.Certainly after the present invention is able to large-scale promotion, just can adopt special-purpose chip to compare.

5) the conforming criterion of pixel also can be divided into severally, and whether two pictures its correspondence position pixel values was identical before and after one was judged exactly; It two is exactly to adopt the fuzzy Judgment mode, for example, set up the color saucer in the edit colors function in the picture application program among the similar Windows, based on the position of pixel in color saucer, the degree of closeness of the coordinate figure of pixel in color saucer of two its correspondence positions of pictures before and after judging, if very approach or be no more than a certain threshold values or whole photo all towards certain tone direction offset some small amount, then can be judged as unanimity, this color saucer also can be three-dimensional or even four-dimensional certainly; The benefit of the mode of this fuzzy Judgment be exactly when light flicker, can Intelligent Recognition when changing, can not produce erroneous judgement, and first kind of mode just may produce erroneous judgement.Certainly, other more complicated conforming algorithms of identification pixel can also be arranged, for example the calculating of contiguous pixel being included together in algorithm is just given unnecessary details here no longer one by one when medium.

After stating algorithm in the use picture being compared, according to drawing pixel multidate information, picture comparison judge module can be autonomous filter out a width of cloth or a few width of cloth picture as formal photo storage, also picture and pixel multidate information thereof can be submitted to the man-machine interaction selective system, further screen.

4. man-machine interaction selective system is according to the pixel comparison result, several pictures and comparison result thereof form or other the form with pixel dynamical system numerical value is listed on the screen, select for the operator, and this coefficient can with embodiment 2 in camera coefficient of dynamics, idea dot factor show in the lump.

Certainly, picture comparison judge module can be namely to bring into operation with the picture acquisition system after the operator makes the purpose of taking pictures in the 1st step, and show its contrast judged result, mark clear or unsharp zone at screen in real time, the operator can adjust the attitude of taking pictures of oneself in real time like this, this point for do with the work of clapping moving object of great use.In fact do like this is exactly after the purpose of taking pictures that collects the operator, just gathers picture continuously and compares judgement in real time.Unique problem is for the CPU of current camera, to accomplish to compare in real time to judge that its operational performance also needs raising that estimation will be developed the chip of special-purpose alignment algorithm just can realize comparing in real time judgement.Under the prerequisite that has realized the comparison of high-speed real-time pixel, intelligence camera system in addition can utilize before and current pixel go dynamically roughly to predict that next step pixel is dynamic, if namely current pixel dynamically is in more stable state, and the dynamic trend of a few width of cloth picture pixels in the past also is to be tending towards more and more stablizing, a few width of cloth pictures that then can infer next step continuous acquisition also will be stable, and increase the density of gathering picture automatically, and can no longer compare and it be selected as formal photo storage or hand the man-machine interaction selective system over to regard to determining.So the operational mode of pixel multidate information can have following three kinds at least, but be not limited only to following three kinds,

1) in continuous acquisition after a series of pictures, analyze, infer its readability, thereby assist the operator to select picture.

2) at the continuous acquisition picture at that time, analyze the readability of each block in real time, thereby assist the operator with clapping.

3) at the continuous acquisition picture at that time, analyzed pixel in real time dynamically and variation tendency, estimated the dynamic of next step, thereby determine to gather the density of picture or select next step width of cloth that will gather or the formal photo of a few width of cloth picture conduct.

5. the operator is according to comparison result, after coefficient makes a choice to many pictures, the man-machine interaction selective system dumps to storage system with selected photo from cache systems, its storage format can be the digital picture form of traditional individual sheet form, it also can be the distinctive form that has comprised the continuous picture of several width of cloth and time corresponding order thereof of the present invention, such form is convenient to post-production, for example in No. 1 picture, take a group photo people's first in nictation, the people's first of taking a group photo in No. 3 pictures has been opened eyes, but group photo people second is in nictation, but other pixels of these two pictures do not have to change substantially, in post-production, just can utilize special software that No. 1 picture and No. 3 pictures are spliced merging like this, produce the perfect photo of a width of cloth, the intelligence camera system, or special-purpose post-processed software even can propose the splicing scheme for the operator, even finish splicing automatically.

The specific implementation step

1. the intelligent photographic method by the auxiliary decision of built-in computer photo opportunity is characterized in that intelligent camera system adopts following steps,

2) the picture acquisition system continuous acquisition picture of intelligent camera system, and deliver storage system;

3) pixel in the picture of the picture of intelligent camera system comparison judge module comparison continuous acquisition, according to the assessment of pixel multidate information, selection picture, or the coefficient of stability of picture and the picture assessed out is submitted to the man-machine interaction selective system, for the operator with reference to selection;

4) the man-machine interaction selective system of intelligent camera system is according to the pixel comparison result, and several pictures and comparison result thereof form or other the form with coefficient value is listed on the screen, selects for the operator, and the most selected picture-storage is to storage system;

Technical advantage

With when clapping mobile object, often require the mobile object clapped clear, and do not do requirement to background is whether clear, the mode of this embodiment of the present invention can judge rapidly which part is clear in a width of cloth picture, which part is unintelligible.No matter be to carry out the picture comparison in real time to judge, select, still afterwards to the picture of having gathered judgements of comparing, can filter out the better picture of effect intelligently, all provide detailed auxiliary reference for photographer's decision-making, selection.
