Description of the Invention: [Technical Field] The present invention relates to an image anti-vibration system and method, and more particularly to a general-purpose digital image anti-vibration system and method. [Prior Art] Digital image anti-vibration technology is divided into three types: (1) electronic anti-vibration, (2) optical anti-vibration, and u) digital anti-vibration. The electronic anti-vibration is mainly used to detect the camera or the camera, and the money is used to reinforce the image. The optical anti-vibration mainly uses the movement of the cymbal combination to achieve the compensation effect. Since the first two types are related to the structure of the hardware, the application range is limited to the processing devices and programs built into the specific equipment. Digital anti-vibration is based on the treatment of Cheng Sijie's unnecessary secret __ compensation effect, because it is a digital image processing program rather than a hardware mechanism such as accelerometer, gyroscope or liquid prism, so it is not online (〇 N-line or offline (Gff_Hne) restrictions, and only a small amount of hardware can be achieved. The methods for digital image anti-reduction can be divided into two parts: social processing unit, mobile vector estimation and motion compensation. The motion vector estimation mainly determines the reliable overall motion vector (GMV). First, the local decoration vector is searched through the money collection ([Er], the entire image can be searched for a more reliable local miscellaneous vector, and then the calculation amount Too large, in the practical application, it is obvious that it is not economical, so there is another comparison method of the calculation of the amount of the calculation, such as the proposed representative point comparison (RPMW, κ · test, etc. (4) edge comparison (ΕρΜ) or S · J. Κο et al. proposed the bit-plane comparison (ΒρΜ), whose main purpose is to reduce the amount of calculations with the same amount of 1307438 without sacrificing too much reliability. - (4), representing the point Rm (Rm) section can be reduced the most The amount of calculation is not the same as the case where there are axial objects in the image, translation during shooting, repeated _ or large contrasting scales in the image, and difficulties in creation. In view of this, the present invention is directed to In view of the above problems, a general-purpose digital image anti-vibration system and method are proposed, which can be used for anti-vibration processing of general or different conditions, and the reliability of the overall shift detection is increased. [Summary of the Invention] The purpose is to provide a digital image _ System and method, the efficiency of the overall motion vector detection when dealing with various abnormal conditions in the low-gas region of the lacking and repeating in the efficient digital processing. The other-purpose of the present invention is provided Image system and method, using background detection to estimate the overall chicken vector to strengthen the background crane compensation effect. The re-purpose of the present invention is to provide the image-enhanced image anti-vibration method to improve the camera's function of preventing vibration during translation. According to the present invention, the digital image anti-vibration system includes: the motion vector estimation subsystem selects the _axis vector from a T-substance, and then uses the inverse three-counter-difference index to obtain the conditional motion vector; The overall motion vector estimates the subsystem connection/quantity estimation sub-secret and receives the local motion vector and the conditional axis vector, and estimates the motion vector, the conditional motion vector, the zero motion vector, and the pre-to-global motion by a number of estimates. Vector receiving integer _; job vector estimator _ _ _ _ computing subsystem parallel movement vector, edit the overall axis vector _ _ vector; homing subsystem 130743 connect the compensation vector rotor and receive the compensation vector At the same time, the image of the root cake is compensated to produce a special image output device. The other digital image anti-vibration method includes receiving a sequence of images from an image device, and comparing the sequence image with the front image. In order to calculate the local motion vector, and then calculate the reliability chain by the triangulation method, the conditional shift axis amount is obtained, and the motion vector of the cage field, the conditional moving direction, the zero motion vector and the previous overall motion vector estimation are calculated. The overall motion vector, then estimate the traditional cumulative motion vector and use the internal integration loop to eliminate the problem of image location obstruction backwardness, and then use the fine-limit 嶋义嫩小术-complement _((10)), and finally compensate the sequence image by compensation And output to an output device. The purpose, technical content, features, and merits of the present invention are more readily understood by the detailed description of the embodiments and the accompanying drawings. [Embodiment] The present invention is a hybrid effect. She still relies on the detection method, and calculates a robust and reliable image motion vector, and then performs a specific chopping process to solve the image compensation vector to make it smooth; Smooth image participation. Please refer to the first figure for the system circle of the present invention; [including two modules: a moving direction module 1 and a motion compensation module 20. The motion vector estimation module 1 receives the image and determines the overall motion vector, and the __: (1)_____ = signal amount, and the coffee object is greeted by 12. Section, the shaft compensation material is mainly to reduce the overall machine «, the material must be surfaced and the part of the axis is moved to make it stable _ like 'by _ subsystem, (1) compensation vector estimation subsystem (4) 1307443 and (ii The hybrid compensator is purely 22. Finally, the stable sequence is rotated; among them, the secret image is 峨, and the sequential sequence image is transmitted. Referring again to the second figure, the local motion vector and the conditional motion vector of the present invention are the operator system = "the original image is transmitted after the previous image represents the point sm and the current image is compared to produce H«_S113, Objects and privates may contain moving objects, panning during shooting, Panyu θ>, lack of feature images or large low contrast areas, etc., resulting in reduced reliability of local motion vectors, so the common phase _ comparison matrix Take the most ^Y S114 5 " y ^ and ask for the co-rotation (4) local cranes to move the 镰 镰 镰 低于 低于 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , SU8. In addition, please refer to the three figures for the reliability index calculation of the invention. The peak of the my axis is the triangle with the minimum value, with a high compensation of one suitable and the bottom of the game. -n as the weighting value', so 2d'n is used as the reliability index. The smaller the value is, the more reliable the reliability is. The moving to the Nacher is the local motion vector of the 4th, the conditional motion vector. Zero-axis vector, front-quantity: The estimation of the overall crane vector is to avoid the search for moving objects and misjudge the overall movement. Therefore, the back-green of the can be used as the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ For example, the object (4), 嶋 (4), _ 嶋 嶋 嶋 嶋 嶋 嶋 嶋 嶋 嶋 嶋 嶋 嶋 嶋 嶋 嶋 嶋 嶋 嶋 嶋 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对 绝对Faces are given different scores'. If the error value is large, the score is given in large order (minus), and finally the score is summed. The moving vector with the smallest score represents the overall shift amount. This method of material evaluation avoids the high contrast characteristics of an area in the image that dominates the overall estimated results. At the same time, the high-period background area is used as the basis for estimation' so that the obtained motion vector is similar to the actual back-movement. The compensation vector estimation subsystem 21 generates a compensation vector based on the overall migration vector to compensate for the image to produce a smooth sequenced image. The estimated square side is as shown in the fifth example of the conventional cumulative motion vector estimation 211, and its calculation formula is (1) CMV{t) = k{CMV{t-1)) + (aaGMV(t) + (1 -a) GMV{t-1))...... 〇) The number of images, CMF (〇 is the first, the compensated motion vector of the image, the 移动 ( (4) The overall motion vector of the second image, 0 small 1 and. Increasing the green will reduce the unwanted vibration effect of the image. 'But it also increases the CMVm. The burial payment will be smaller. Especially when the image is shifted, the situation is more serious. Therefore, the integral circuit 212 is added to eliminate the image. The problem of positional backwardness caused by translation, and the wave of _CMy value is added to ensure the effective image area after compensation. The calculation formula is (2) C_)=k, CM^-l)+[aeGM ^)+(1_a)··^,c by (4) CW_Uf)=CMVJ(t-\)+CW{t) ......

See Figure 6 for the internal integration loop 5〇2 improved results: (a ) is a phenomenon in which the traditional method is seriously backward in the position caused by the translation of the image 1307443, and (6) is the riding of the hair. (4) The method has a significant improvement on the positional trajectory caused by the image shifting.
