Description

201039291 IX. Description of the Invention: [Technical Field] The present invention relates to a method of pronunciation learning and correction, and more particularly to a method of using a mirror image and an image composition. [Prior Art] The General Language Training Center or the Medical Research Center often uses the language of the language to learn how to perform the pronunciation practice and the treatment of the face and mouth. There are four common methods: general teaching method, rehabilitation bridge method, acoustic wave analysis method and computer self-study method. The first general teaching method is shown in Figure 1. ❹ Ο Please refer to Figure 1 for a face-to-face illustration of the practice embroidery. As shown in Figure 1, the traditional methods of pronunciation learning and correction are usually corrected by the instructor (or orthodontist, teacher) 11 and the learner (or student, patient) 12 in a face-to-face manner. And practice. For example, when the instructor speaks the pronunciation and says "丫!", the learner 12 then opens π and says "丫丨". According to the sound of the learner 12 and the movement of the tongue and tongue, the correct green and repeated exercises are given. The advantage of this general teaching method is that: - the teaching of the pair has a significant effect on the teaching results than the -to-multiple teaching, and the different methods of correction can be provided for the learner 12 not to make the wrong reason. The disadvantage is that if both sides are young, such a face, face may have an "unnatural" feeling of men and women. Or the other party has the "bad breath" embarrassment. In order to improve the lack of embarrassment caused by this "face-to-face", in recent years there has been a replacement by one, as shown in Figure I. Please refer to Figure 1 for the practice and correction of traditional mirrors. Such as 囷一A, some schools or kindergartens, usually also use a common plane mirror 13 by the teacher U to teach the students 12, the teacher u and the students 12 are together ^ plane mirror 13, by the plane mirror _ age, county Teacher = can be a mirror of their own. The large-sized f-plane mirrors 13 can also simultaneously see the student's 12-ported oral motion mirror 12a and the teacher 11 scaled lip-shaped motion mirror ua. The first type of rehabilitation correction method, such as 囷-β. 5 201039291 Please refer to Figure 1 B for the rehabilitation correction method. In recent years, there have been large medical centers such as the Rehabilitation Section of Taiwan Veterans General Hospital, which provide a set of rehabilitation correction and practice equipment. Such a device comprises a large conventional flat mirror 13 for use with a color camera 32, as shown in Figure 1b. In the first B, both the patient 12 and the orthodontist 11 face the front side of the ordinary plane mirror 13 by the mirror image of the plane mirror 13 to see each other and the other party, so as shown in Fig. 1A, neither side is necessary. The "face-to-face" opposites can see each other. Such as 囷B' This ordinary plane mirror 13 is nailed to the wall of the correction room, and a corner of the patient 12 and the orthodontist 11 are located at a far corner of the back, and a color camera 32 is suspended from the far side. The image capturing can be performed on the learning mouth motion of the patient 12 reflected by the ordinary plane mirror 13.囷B is different from 囷一A, the difference is that there is a color camera 32 in Fig. 1B. The necessity of setting up a color camera 32 is mainly to photograph and archive the learning and correction process of the patient 12 for analysis of other teaching or corrective treatment. The remoteness of the color camera 32 is mainly to prevent the "tension" or "uneasy" mental emotion that may be generated when the patient 12 (especially a part of the language disabled person or the mentally handicapped person) directly sees the color camera 32. As a result, there is a gap between the images taken and the correction results.既然 Since it is necessary to set up a color camera 32, it is also considered to be hidden. The next step is to pay attention; is the image of the mouth movement captured and the actual mouth movement consistent? If inconsistent, does such a drop affect the analysis of the conformational treatment? In fact, does the ingested lip motion image match the actual lip motion? In general, the position of the color camera 32 should be the most appropriate for the mirror position of the ordinary plane mirror 13. That is to say, the position where the color camera is placed is directly placed in front of the front of the user (patient 12 and Dwarf Zheng 11), and is the position for obtaining the best "mouth-and-lip" action.囷三A has a detailed description. The color camera 32 is placed directly in front of the front of the user. There are two methods commonly found in other fields: 'First, a hole is drilled in the front mirror surface of the ordinary plane mirror 13, and the color camera 32 is hidden in the ordinary plane mirror 13. At the rear, the lens of the color camera 201039291 is exposed at the hole to facilitate the image acquisition. For example, dig a small hole to accommodate a pin-hold camera. However, this will destroy the effect of the specular reflection of the ordinary flat mirror 13, and it is especially important that the image is destroyed by the small hole to form an incomplete mirror image. Secondly, a clip is attached to the color camera 32, and then the color camera 32 is placed on the edge of the frame of the ordinary flat mirror 13, as if the popular webcam PC Cam is held on the edge of the frame of the notebook. Can capture a more accurate image. However, this exposed color camera 32 lens will also cause the patient 12 to face the "tight" or "uneasy" mood of the color camera 32 lens. 〇 〇 Therefore, if a device that uses both the ordinary plane mirror 13 and the color camera 32 is used, the general language training center or the medical research center almost always has such a problem that it is not easy or impossible to obtain the best "lip-and-mouth" shooting position. At present, in the language learning and correction method, for example, "the device and method for interactive vocal pronunciation" of the Republic of China Invention Gazette No. 2_1, and the "Right and Right Device and Method" of the Republic of China Invention Gazette No. 200515368, Chinese People's Patent Gazette Announcement No. 5_5, "Auxiliary Words with Accented Prompts, Learning Systems and Methods", Republic of China Invention Patent Certificate No. (3), "Portable Language Reading and Pronunciation Residents and Methods", China The Republic of China Inventions J Report No. j00701131 "Visualized Interaction" Digital Learning Language Pronunciation Grading System Invention Disclosure No. 2_4613 "Image of Face Diagnosis ίίϋίίί 1 etc*" These patented technologies are mostly silk sound waves, and Pure photography and green positive 'have not found a device that uses a common flat mirror 13 machine 32. It is enough to be visible, in language learning and problems. Flying flawless to get the best "lip and tongue action" photography position. Teaching methods, such as the second.

Formula === At the meeting, there is a so-called electric 7 201039291 field dry, for example, the pronunciation of the word "eat" is now in the teaching of Fan Zhong. Among them, the screen of the computer 2 includes a lip that can display the language teacher's commentary, the language teacher's 11 standard pronunciation "如" = the image of the image 11b, "cat", and the image of the "cat" font. The secret of the language-like teaching, most of them use the language teacher 11 as the main character' and let the learners learn by themselves before the computer. ί = person ^1 If you have a mistake in learning $, you must have limited success according to the painting interest displayed by the computer. It is not easy to cause learner 11 to learn by himself in front of the computer. ο The fourth sonic teaching method, as shown in the figure Second.

It is said that the computer has come to a large-scale school or medical research center at home and abroad, and there is a computer-based sonic language teaching system, which also includes a computer.

Such educational institutions (such as the University of Taiwan) have obtained sufficient subsidies from the Ministry of Education to use: ^? The third type of audio-based language-based language teaching system, and the fourth brain ^ • sonic-type speech system for use together. The patent information previously disclosed by the inventor: for example, the medium-profit certificate M326646, which was applied for in April 2007, "the key-type hemispherical cover photographic device", and the new face of the Shenhua Republic of China patent certificate No. 1 in September 2007 "The double-layer anti-shield device for surveillance photography", the 2nd year of June, the application for the new disclosure of the patent certificate of the Republic of China, "the wide-angle reflex mirror device from the 201039291 cash dispenser", etc. Coated lens and a color camera. A coated lens of this type of device is a non-planar spherical shape. It has the decorative effect of spherical wide-angle reflection. Its decorative function is only to hide and decorate its color camera, so that the criminals can not find the color. The existence of a camera cannot deliberately avoid its monitoring, and it is applied to anti-theft surveillance. As for the anti-theft monitoring coating mirror, the mirror effect can be achieved by hiding the camouflage. The degree of brilliance does not care. In previous embodiments of such devices, it was found that the reflectance of the coated mirror of such devices to incident light is not high, and the specular reflection effect caused by the reflectance between about 50% and 60% is sufficient. The color camera set behind the coating mirror of such a device achieves the effect of hidden camouflage. If the reflectance reaches about 80%, the key mirror of such a device is too bright and dazzling, and it is easy to attract the attention of the unscrupulous. The chain mirror of the anti-theft monitoring device is different from the plane mirror used in the second rehabilitation correction method disclosed in the prior art: the rigid short plane mirror must be flat and must have a bright mirror surface to be correctly It clearly reflects all the "mirror" images of the user in front of the coated mirror, allowing the user to achieve the practice of practice and correction through the reflection of the coated mirror. The coated mirror of such anti-theft monitoring device should not present a bright mirror surface, so as not to cause easy The content of the lawless person. [Summary of the Invention] U First, the present invention is applied to a device for pronunciation learning and short positive method, and The second method of rehabilitation and the anti-theft monitoring device disclosed in the technology, the matching mirror and the color camera are matched, and the comparison is as follows: (1) Mirror: (a) Mirror property: (al), the mirror used for rehabilitation is a general mirror, and the visible light incident on the mirror surface of the general mirror cannot penetrate the general mirror surface. (a2), the mirror used in the present invention and the mirror for anti-theft surveillance are all chain mirrors. The visible light incident on the mirror surface of the coated mirror can partially penetrate the coating mirror. (b) Mirror use: (bl), the size of the anti-theft monitoring mirror is not limited, and the minimum size is larger than the size of the color camera lens. For example, if the area diameter is larger than 3 cm, the 9 201039291 color camera lens can be hidden. (b2) The mirror used in the present invention and the mirror used for the rehabilitation end are limited in size. The minimum size is larger than the pre-camera learner 12 and correction. The size of the two sides can be juxtaposed, for example, the area is 4 cm + 25 cm. Otherwise, neither the learner 12 nor the orthodontist 11 can see the image that he and the other party reflect. (c) Mirror surface: (cl) The surface of the anti-theft monitoring mirror may be planar or spherical. (c2) The mirror used in the present invention and the mirror used in the rehabilitation structure must be planar, otherwise the reflected image may be distorted. (d) Color camera placement: ο (dl), the color camera placement position for rehabilitation is placed on the back of both the learner π and the orthodontist 11 (see Figure 1 β). (d2) The color camera used in the present invention is placed directly in front of both the learner 12 and the orthodontist 11. (The color camera for anti-theft monitoring can of course also place the front side of both the learner 12 and the green teacher 11', but it does not make sense, because there is no clear specular reflection effect, and if it is only hidden, it should not be placed directly in front of the user). (e) Use of a color camera: (el) The use of the color camera of the present invention shall be notified prior to activation. ❹ (e2), anti-theft surveillance The use of color cameras does not need to be notified before activation, so secretly enabled. Take (f) the problem solved by the combination of the rhodium-plated mirror and the color camera: (Π), the present invention utilizes features that can generate mirror images and images to achieve learning and correction. This is less i12), anti-theft surveillance is the use of features that can produce mirror images to achieve a hidden color camera. In terms of the method and use of pronunciation learning and correction: It is obvious that after the mirror of the present invention is combined with a color camera, the method for learning and correcting the pronunciation of the present invention is The second type of rehabilitation correction method disclosed in the technique (Fig. _B) is very similar. However, the method of the present invention is to solve the problem that the second rehabilitation correction method has occurred in the long term and cannot be solved. 10 201039291 That is to say, the present invention has an unpredictable effect on the method of pronunciation learning and correction. The effect is that in the process of learning and correct photography, a "correct" position of photography can be obtained. The method of rehabilitation correction for the pronunciation learning and correction method uses a mirror 13 and a color photo 32. In the method of the present invention, a mirror 31 and a color camera 32 are also employed. The main differences are: (1) Mirror 13 is an ordinary mirror, and mirror 31 is a mirror that is coated. The two mirrors are produced differently and in different ways. (2) The color cameras 32 of the two are substantially the same, but the two are installed differently. The effect of capturing images is different. For the descriptions of (1) and (2) above, as shown in the third and third figures. Please refer to Figure 3 for the imaging diagram of the rehabilitation short positive method. Figure 3 includes a human body A, a mirror 13 and a color camera 32. In Fig. 3, the mirror 13 is an ordinary total reflection mirror, and the human eye A sees its own mirror image μ on the mirror surface through the mirror 13 to "reflect" the light Lb. The color camera 32 photographs the "reflected" light La of the human body toward the mirror 13, and after the image is taken (if an image display is connected), the image A1 of the human body A can be displayed. That is to say, the color camera 32 takes in the image gram, and the 〇 seen by the human body A is the mirror image A2. In Fig. 2, an angle 0 exists between the two lines of the reflected light La and the reflected light Lb at an angle. The larger the angle of the angle 0 is, the error that the color camera 32 picks up the "shadow" image A1 of the human body A and the "mirror" image A2 of the human body A, and the gap between the image Ai and the mirror image A2. It is bigger. Especially when observing small changes in the human body's 4-port type, a significantly different observation will result. Please refer to FIG. 3A for an imaging diagram of the present invention. Figure 3A includes a human body A, a mirror 31 and a color camera 32. In Fig. 3A, the mirror 31 is a mirror coated with an optical film, which partially reflects incident light on the mirror 31 (presenting a normal mirror 13) and a portion of the mirror 31 under the interference of the optical film. Penetrate the past in the mirror. This penetration of the past part of the incoming light enters the color camera 32 lens hiding behind the mirror 31, imaging the color camera 201039291 32.

Among the three people, the human body A sees its own mirror image A2 on the mirror surface through the mirror 31 to "reflect" the light Lb. The color camera 32 captures the "transmissive" light La of the human body A through the mirror 31, and the color camera 32 can output an image A1 of the human body a after taking the image. In Fig. 3A, the reflected light La and the reflected light Lb are parallel to each other, and are nearly close to each other. That is to say, the angle of this angle 0 is almost zero with respect to the third. The image A1 indicating that the color camera 32 has taken in the human body a is almost the same as the image A2 in which the human body A sees itself. It can be seen from the comparison between the above figure 3 and the third A; ❹ the method of pronunciation learning and correction of the present invention is similar to the structure of the second rehabilitation correction method (such as 囷B) in the prior art. However, the oral image taken in the pronunciation learning and correction method of the present invention is obviously larger than the oral image taken in the second rehabilitation correction method, compared with the actual oral movement of the human body. "correct. This correct image, in the practical application of pronunciation learning and correction, for example, "Why is it wrong?" "Where is it wrong?" and "I find the best way to correct it" is a short success. One of the conditions. The coating mirror 31 is formed by bonding a layer of optical Q-film to a flat transparent substrate. Due to the interference effect of the optical film after coating, the incident visible light is split in the coating mirror 31 into a reflected light which is specularly reflected by the coating mirror 31 and the other transmitted light penetrates the mirror surface of the coating mirror 31. Where the 'transparent substrate is coated with a metal film, such as aluminized (A1) or silver plated (Ag), the metal film will be "absorbed" from the incident visible light in the mirror surface of the coating mirror 31. Loss of light energy. If a plurality of dielectric film (muld_layer coatings) are plated on a transparent substrate, for example, a film coated with an oxide film such as TiCh or Si〇2 alternately coated is transparent in both visible and infrared domains. That is to say, the plated multi-layer dielectric film is almost free of "absorbed" light energy from the incident visible light in the coating mirror 31. If other complex optical calculations (such as scattering, birefringence, etc.) are ignored. 12 201039291 When the coated mirror 31 is a metallized film, the incident light is incident on the coating mirror 31 and is divided into a reflected light, a transmitted light and an absorbed light. When the key mirror 31 is a key dielectric film, the incident light is incident. After the coating mirror 31 is divided into a reflected light and a transmitted light. Obviously, the plated dielectric film is more efficient in light energy than the metallized film, but the metallized film is lower than the plated dielectric film in terms of manufacturing cost. Under different application environments and different application conditions, a forged metal film or a plated dielectric film' or a metal plated film and a plated dielectric film may be used alone as appropriate. The transparent substrate used in this embodiment can be roughly divided into optical grade transparent glass (clear glass has cyan, or whiteboard glass and BK-7, etc.) and transparent resin (such as pc, polycarbonate carbonate resin, PMMA acrylic). Big class.透明 Before the transparent substrate is coated, it must first have high transparency, and the surface quality must be strictly required. ‘There should be no defects such as streaks, pores, whitening, halo, black spots, discoloration, and poor luster. The transparency of visible light to a transparent substrate is generally affected by factors such as reflection, penetration, absorption, and scattering of "light." In the present embodiment, the scattering and absorption of incident light by the optical grade transparent substrate is almost negligible in comparison with the application of the present embodiment. In the coating mirror 31 of the embodiment of the present invention, there are many coating mirrors 31 using a plated dielectric film, and more than a metallized film coating mirror 31, mainly under the same transmittance, plating a dielectric film. The coated mirror 31 is more like a conventional mirror than the metallized coated mirror 31. For example, the coated mirror 31 coated with a dielectric film has a reflectance of up to 80%, but the coated mirror 31 of the metallized film is only 55%. In the coating mirror 31 of the embodiment of the present invention, the dielectric film coating technology on the coating mirror 31 is compared with the prior art "a double-layer shield device for monitoring photography" and the like. After a year of testing and improvement, it has made significant progress. For example, in the same spectrum (the transmittance T% in the visible light 4〇〇n|TW〇〇nm portion, the average is about 20%. In the infrared 780nm~1, the transmittance of the 〇〇〇nm portion T In the case of % 'average between 95% and 96%', the number of forged layers of the plated dielectric film 31 of the embodiment of the present invention is 12 layers, and the prior art "a double-layer shield device for monitoring photography" The number of layers of the plated dielectric film coating is about 18 to 42 layers. This technique for reducing the number of coating layers is an experience and improvement obtained in the prior art. In the mass production, the coating process time is reduced and the output is relatively increased. In the present embodiment, the reason why the coated mirror 31 using the dielectric film is replaced with the coated mirror 31 of the metallized film is more apparent in the present embodiment. However, the coated mirror 31 for the metallized film is not completely unusable. To avoid and reduce the chance of the design of the present invention in the practice of pronunciation practice and correction, the coated mirror 31 is defined as a plated dielectric film or Metallized film. The capsule mirror 31 in the embodiment of the present invention is applied to the characteristics of the metal film and the forged dielectric film, and does not describe the coating technique. Another feature of the plated dielectric film 31 in the embodiment of the present invention is that the plated film has a high transmittance in the face of infrared rays, and is suitable for a device having an operation of an infrared remote controller. The matching device of the coating mirror 31 and the color camera 32 in the embodiment of the present invention is to solve the problem that has existed in the prior art for a long time. The problems in the prior art are as shown in FIG. 1B and FIG. 3, that is, The problem that the color camera 32 is not easy or unable to capture the image of the correct position. Especially for the learner U "mouth error" action process and the images taken after correction, it is not easy or impossible to see the appropriate and correct image. In the embodiment of the present invention, the coating mirror 31 is further supplemented by a color camera 32 having a telescopic magnifying and movable displacement device, so that the present invention is applied to the method of pronunciation practice and correction, in addition to solving the long-term in the prior art. In addition to the existing problems, it is more likely to have the effect of language teaching and medical rehabilitation and the possibility of universal promotion. In summary, the coated mirror 31 of the present invention is supplemented by the color camera 32 and used in the matching practice, and is applied to the method of pronunciation practice and correction, in addition to each having a separate function (for example, the coated mirror 31 functions as a mirror, Other than color camera 32^^photo_function). In addition, the mirror 31 also functions as an auxiliary function for concealing and protecting the color camera 32. #巧前技术f通平 Listening to 13 lining line gambling and using it together, in the practice of pronunciation practice and correction, in addition to playing a separate master, such as ordinary plane mirror 13 to play the role of mirror, with color camera 32 m shadow The ordinary flat mirror 13 does not function as an auxiliary function for the color camera 32 except for the function). 14 201039291 The color camera 32 used in the embodiment of the present invention, more because of the application of the attached telescopic lens and the drivable device 331 (such as the six), makes the method of pronunciation practice and correction more clear in the present invention. Shoot more and more correct mouth shape. Image. These more correct lip images, when replayed at a "slow" speed, do play a very important corrective role in multiple experiments of practice and correction methods. The technical solution adopted by the present invention achieves the following effects: 1. After using the device in which both the coating mirror 31 and the color camera 32 are used together, the correct image capturing angle can be taken.

Second, let the learner 12 itself "see" his own "mirror" image like A2, and the "shadow" image 8: including the change from the wrong to the correct mouth shape, by mirroring the combination of A2 and image A1. Features, which enhance the fun of learning, is a better practice and correction method in one-on-one teaching. Third, the mouth image of the "wrong" and "green positive process" of the learner 12 can be easily preserved in the mind of the learner 12 after being corrected. =, the instructor 11-side gives the learner 12 the appropriate short-term on the spot, on the other hand, he will record and videotape the progress and process of the school, in order to grasp the learning error and the way for the teacher to Research _ positive treatment analysis has been referenced to develop a more effective correction method. 5. In the method of practicing f and correction, the axis gives the example of the Chinese national phonetic note with the =, but for other exercises in the field that involve changes in the mouth, such as corrective reading of color nerve damage. The practice f and so on also play the practice and touch ° & [Embodiment] Please refer to Figure 4 for the schematic circle of the device embodiment. FIG. 4 includes an imaging mirror 30, an audio-visual access device, a device 36, and a learner 12 and a viewer sitting in front of the imaging mirror 30. The imaging lens 30 further includes a coating mirror 31. Color ^^ opaque frame body 33, a control box 34. / and a 201039291 where both a learner 12 and a mentor u face the coated mirror 3 and can clearly see the mirror image reflected by the opponent and the other on the coated mirror 31. For example, in FIG. 4, the learner 12 sees his own image on the coated mirror 31 as 丨2a, and the instructor sees his own image on the coated mirror 31. That is, the learner 12 looks at the coated mirror 31. At the same time, the instructor ^ also sees his own mirror image Hb and the mirror image 12a of the learner 12 on the coating mirror 31. * The coated mirror 31 is formed by coating a planar transparent substrate with an optical film. The coating mirror 31 of this embodiment adopts a multi-layer dielectric film on a transparent substrate. The incident light of the coating mirror 31 is reflected a large amount on the surface of the coating mirror 31 to form a bright mirror effect under the interference phenomenon of the optical film. 〇 From the optical film interference phenomenon, when the light is perpendicularly incident on the single layer film, and the optical thickness Nd (which is the product of the film refractive index and the film thickness) is (2λ()/2), λ〇, (3 λ〇/2 )...the reflection intensity of the film is constant for the wavelength; if the optical thickness Nd is (in /4), (3 λ〇/4), (5 λ0/4)··· 'the reflectance will be the maximum or minimum The value, and its value is determined by whether the refractive index η of the film is larger or smaller than the refractive index of the substrate. When η > nS, the reflectance is a maximum value, and at η < ns, the reflectance is a minimum value. The optical thickness of one layer is an odd multiple of a quarter of the wavelength of the incident light, which causes the reflected wave to form destructive interference, which results in an anti-reflection effect of the reflectivity. However, the reflectance for other wavelengths is not zero, so in order to obtain a broad reflectance in the visible light range, it is generally a multilayer structure. The appropriate reflectance can be obtained by appropriately selecting the refractive index of the film layer and the film layer design. For example, a single layer of magnesium fluoride (MgF2, n = 1.38) is plated on the surface of glass (ΒΚ7, η=1·53), which is an antireflection film of a simple structure. In contrast, if a glass material is coated with a material having a sufficiently high refractive index, it will greatly increase the reflectivity of the glass surface, so that the film can be used as a simple beam splitter to split the incident light. A single layer of titanium dioxide (Ti〇2, η = 2.2) or zinc sulfide (ZnS, η = 2.35) film is often used for this purpose. The reflectance is about 30%. Basically, the superposition of a single layer film is a multi-layer film. When using multilayer films, we can use high and low refractive index thin film stacks according to our needs to make a variety of film designs to produce the optical properties we require. Common such as anti-reflecting mirrors, high-reflecting mirrors, cut-off filters, band-pass filters, band-stop filters, and spectroscopic effects corresponding to this embodiment. The emergence of computers, not 16 201039291 but makes the optical film design (computer-aided software) more convenient, and the related research of optical film is even more rapid. Up to now, the difficulty in the fabrication of optical films has been reported to be less than ever. As long as the characteristics are reasonable, for example, the use of the coated mirror 31 of the present embodiment, a suitable multilayer film structure can always be designed. Since the coated mirror 31 forms a low transmission phenomenon under the interference of the optical film, the transmitted light transmitted through the coated mirror 31 can be imaged by the color camera 32. Most color cameras 32 today have video and audio outputs for outputting images and pronunciations of learner 12 and instructor 11 via color camera 32. For a clearer sound, you can quote a high-sensitivity microphone and a stable audio amplifier.

〇The common color camera 32 is mainly divided into CCD (Charge-Coupled Device) or high-end CMOS (Complementary Metal Oxide Semiconductor) camera, which is mostly CCD camera. The resolution of imaging mainly refers to image sensing. The sensor's sensitivity quality is generally divided into high, medium and low resolution on the market. In this embodiment, a mid-resolution CCD camera is used. Currently, a commercially available color camera 32, such as Sony's Sony, Sharp digital processing circuit ( The DSP) has a Mirror function, which is referred to herein as the mirror function; the image captured by the color camera 32 is displayed by the image display 36, as shown by the mirror, left symmetrical left and right边 Edge symmetry right. According to the current commercially available color camera 32 specification, the minimum illuminance that can be imaged is about 1 to 标准 under standard lens. 5Lux, high-end products have 0·05Lux in color models, black and white models have 〇 · 〇〇〇5Lux. That is to say, the visible light transmittance of the coated mirror 31 of the present embodiment is about 2%, in the classroom or correction The general illumination of the room (for example, 200 to 400 Lux) is not problematic for the color camera 32 used in the present embodiment to penetrate the coating mirror 31. The opaque frame body 33' wherein the main function of the frame body 33 is three: Supporting the coating mirror 31 and the color camera 32, the coating mirror 31 and the color camera 32 are easily assembled or connected together. Second, blocking the interference of external incident light, so that the forging mirror 31 has a black (or deep) color background. It is easy to form a bright mirror surface. Otherwise, the interference light behind the coating mirror 31 causes the coating mirror 31 to appear as a semi-transparent lens, which cannot be formed like a mirror 17 201039291. It is especially easy to see and hide in the coating mirror S1. The color camera 32 behind. The third is to block the interference of the external human hair. 'The color camera 32 is not affected by the secondary reflection and affects the image quality. The inside of the frame body 33 is accommodated with a color camera 32 ^ the side of the frame 鳢 33 opening There is a coating mirror 31. A control box 34 can be disposed inside the base of the frame frame 33. The light transmission of the frame body 33 affects the quality of the color camera 32 inside the frame body 33. The definition of the frame body 33 is supplemented by: If the image mirror 3 of Figure 4 is placed on the wall by the decoration design (such as 囷 Β 不), the umbilical wall is either a cement wall or a timber wall, if there is a wall When the space lens 31 and the indwelling color camera 32 are excavated so that the space also has the above three functions of the mirror frame 33, the space in the wall is not a mirror frame 33, but in the present invention In the embodiment, it is also regarded as one of the opaque mirror frames 33. That is to say, the three functions of the mirror frame 33 are equally theoretically the same as the mirror frame 33. The control box 34 mainly controls the activation of the color camera 32 and the audio/video access device 35, and allows the learner 12 to have the right to activate the photography and video recording by the learner 12 when necessary. . That is, the control box 34 can display, store, and read the images taken by the color camera. In addition to the various indicators, the control box panel can also hide a microphone (mike) 341. The video access device 35 includes images captured by the color camera 32 for storage and playback (including playback at a speed that can be adjusted). It can also be read into the data input from the image memory or database external to the audio/video access device 35. An image display 36' can display an image taken by the color camera 32 and an image input by the video access device 35. In practical applications, the image display 36^ can be replaced by a projector. The 'one audio/video access device 35' and one image display unit 36 can be placed together inside the control box 34 or both together outside the control box 34. It is also possible to place the two independently inside or outside the control box 34. 77 See 囷5 for a schematic of reflective processing. 201039291 As shown in Fig. 5, visible light L1, when incident on the coating mirror 31, forms a reflected light Lla and a penetrating (or transmitting) light Lib. The reflected light Lla causes the coating mirror 31 to form a mirror. The transmitted light Lib enters the lens 32a of the color camera 32 for imaging. The other visible light L2, when incident on the coating mirror 31, forms a reflected light L2a and a transmitted (or transmitted) light L2b. The transmitted light L2b is incident on the inner surface 33a of the opaque mirror frame 33. Further, the surface 33a is reflected to the inner surface of the coating mirror 31 to form a re-reflected light L2c, and then the reflected light L2c is reflected again into the lens 32a of the color camera 32 for imaging. When the reflected light L2c after the two reflections enters the lens 32a of the color camera 32, the image of the color camera 32 is reflected (or ghosted), which affects the image quality of the color camera 32. To solve the reflection of the reflected light L2c, there are two reflective processing methods: First, an opaque black soft cover 32b can be placed around the lens 32a of the color camera 32, and the reflected light L2c can be blocked. The black soft cover 32b must be close to the back surface of the coating mirror 31, and there should be no light-transmitting gap as much as possible. Thus, the reflected light that is not directly in front of the lens 32a, such as the reflected light L2c, is softened by black. Set 32b blocked. The black soft cover 32b is preferably black or dark. If it is white, it will cause white reflection, which makes the white trap shadow appear on the surface of the coated mirror 31. Second, a black surface or a rough surface 〇33b' is formed on the inner surface of the mirror frame 33. Then, the reflected light L2b is absorbed by the "black" of the black surface, or is scattered by the "roughness" of the rough surface 33b, so that L2b Not easy to form. That is to say, indirectly makes L2c not easy (or impossible) to form. Therefore, the image of the color camera 32 is not reflected. When the color camera 32 in the imaging mirror 30 is far enough away from the learner 12 in front of the coating mirror 31, the range in which the color camera 32 can be photographed is insufficient to accommodate both the learner a, or the learner 12 and the instructor 11. In the case of images, there are three methods that can assist the range in which the color camera 32 can be photographed. The three methods of assisting the photographing range are: - a color camera % that can be added to the image mirror 30. For example, a special photographer, 12, and a special photographer. Second, the color camera lion _ _ has a color camera 32 lens with the function of stretching the col (extension and automatic 19 201039291 focus). In this embodiment, a 4mm~9mm electric (a micro DC motor drive) zoom lens (about three times of zoomable magnification) is used, and the user can be photographed in front of the coated mirror 31 (learner 12 and instructor 11). Clear image at the time. For example, in the case of the video recording of the "repeated error" mouth-type action, the preferred method is to give a magnified shooting to the mouth-shaped action that always makes a mistake, so as to more clearly see "wrong". Image. In addition to manual operation, the commercially available electric zoom-type zoom lens can be remotely controlled by an infrared remote control, and the infrared remote control receiver is usually placed around the telescopic lens. That is to say, if the keyhole mirror 31 of the present embodiment is plated with a multi-layer dielectric film, the infrared signal emitted by the hand-held infrared remote controller can easily pass through the coating mirror 31' to easily control the infrared receiving in the coating mirror 31. end. Third, a driveable device is added to the imaging mirror 30 for moving the color camera 32 for a more appropriate position. Please refer to the diagram of the application of the drive unit. Please refer to 囷六A as a schematic diagram of the drive unit. Please refer to Figure 6B for a schematic diagram of the front loading of the drive unit. When the use environment is not suitable for adjusting the positions of both the learner 12 and the instructor 11, or even if the seat positions of both the learner 12 and the instructor 11 are adjusted, the image to be taken cannot be photographed. The scope of the time. It can be attached to a driveable device 331 on the color camera 32, such as six, six, and six. As shown in FIG. 6 , FIG. 6A and FIG. 6B , the drivable device 331 includes a support frame 331 a , a horizontal rod 331 b , a horizontal sliding seat 331 c , and a pushing handle 331 d » as shown in FIG. It is fixed inside the frame boat 33 by a support frame 331a. A horizontal sample 331b is also fixed to the support frame 331a. The horizontal rod 331b is composed of two elongated rods. The two elongated rods of the horizontal rod 331b are provided with a horizontal horizontal sliding seat 331c, and two horizontal holes are formed beside the horizontal sliding seat 331c for passing through two elongated fixing rods, by two lengths The two fixing manners of the strip-shaped fixing rod can make the smooth seat 331c slide stably in the horizontal direction on the horizontal rod 331b. If a color camera 32 is provided on the horizontal slide 331c, the color camera can be made 20 201039291 32 free to horizontal displacement in the horizontal rod 331b±. A sliding handle 331d extends from the rear of the slider. The shifting handle is moved by a finger in an open slot behind the frame 33 so that the color camera 32 can be moved in such a manner that a more appropriate photographing position can be found before the learner 12 and the instructor 11. If it is inconvenient to manually push the handle 331d, a small DC motor may be attached to the horizontal sliding seat 33lc for electrically driving the horizontal sliding seat 331c. The power starting switch of the direct current motor may be disposed on the panel of the control box 34 for the instructor. u operation. From the application of the driveable device 331 of the sixth, and then look at the black soft cover 32b of Fig. 5, the U two instructions seem to be a problem. The black soft cover 32b of Fig. 5 must be close to the back surface of the coating mirror 31, and there should be no light transmission gap. However, it can be seen from the movable device 331 of FIG. 6 that the color camera 32 is movable, and after the black soft cover 32b of the color camera 32 lens 32a is placed, and then closely adjacent to the back surface of the coating mirror 31, When the color camera 32 moves, the back surface of the coating mirror 31 is scratched. Therefore, when the device has the driveable device 331, the black soft cover 32b must be kept at a small distance from the back surface of the coated mirror 31 to avoid scratching the back surface of the coated mirror 31. Thus, if a reflection phenomenon is found, another reflection of the reflected light L2c is taken, that is, a black surface or a rough surface 33b is formed on the inner surface of the sharp frame 33 (as shown in Fig. 5 and its description). The 12-layer dielectric film technology and the manufacturing method adopted by the coating mirror 31 in the embodiment of the present invention are as follows: Prepare a plurality of transparent PC plates having a thickness of 3 mm and a length of 40 cm and a width of 25 cm as a substrate, and after washing, the hot air is used. Dry quickly, no water left. Then follow the steps below. (a) Input process data: Input the following film and film thickness design data into the control computer of the coater. The selected membranes are Ti〇2 and Si〇2. The number of layers was 12, and the physical thickness was measured in nm. The first layer: the key Ti〇2. Coating thickness = 31. 04 nm Second layer: Si〇2 plating. Coating thickness = 68. 82 nm The third layer: Ti〇2. Coating thickness = 48.84 nm 21 201039291 Fourth layer: Bond Si〇2.

Film thickness = 141. 89 nm The eleventh layer: the bond Ti〇2. Coating thickness = 37.43 nm Twelfth layer: Si〇2 plating. The thickness of the film is 236. 03 nm where Ti 〇 2 : 折射率 The refractive index at a wavelength of 400 nm is 2.53. The refractive index at a wavelength of 450 nm is 2.449. The refractive index at a wavelength of 500 nm is 2.397. The refractive index at a wavelength of 550 nm is 2.362. The refractive index at a wavelength of 600 nm is 2.336. The refractive index at a wavelength of 650 nm is 2.318. The refractive index at a wavelength of 700 nm is 2.304. The refractive index at a wavelength of 750 nm is 2.293. The refractive index at a wavelength of 800 nm is 2.284. The refractive index at a wavelength of 850 nm is 2.277. °。 Si〇2: The refractive index at a wavelength of 422 nm is 1.49.

(b) Place the transparent substrate and the film to be plated; place several pieces of the transparent PC plate into the fixture, and place the film Ti〇2 and Si〇2 into the crucible in the coating machine. (c) Process condition setting; 22 201039291 The conditions for coatable conditions include vacuum pressure and temperature. For example, a chain film machine (LP-1300) made in Taiwan is used as an example of a chain film. The vacuum should be 2χ1〇—5 torr and the temperature should be adjusted to room temperature (cold treatment). (d) monitoring the film thickness and the film layer;

G

Whether the thickness of the plated film reaches the designed thickness is determined by a quartz film thickness meter or an optical film film meter. The thickness of each film is controlled at ±1%. The working gas of the ion source is properly filled with oxygen, and an appropriate amount of oxygen is also charged near the evaporation source. The automatic control system of the coating machine with spectral scanning of this embodiment can be compared at any time, and whether the optical effect of plating the film layer is consistent with the theoretical value, if not, it is necessary to quickly calculate the next layer or even other layers in the future. Corrected. And, whether the film layer is at the last layer (for example, whether the number of layers has reached the 12th film layer). After the coated PC substrate is taken out, it starts to deflate (injecting air into the vacuum chamber), waits for about ten minutes to cool down, and then opens the door to take out, forming a coating mirror 31. Please refer to FIG. 7 for the spectrum of the coated mirror 31 after completion. In Fig. 7, a spectrogram of the coating mirror 31 is taken out by a U-4100 spectrometer manufactured by Hitachi, Japan. The ordinate is the percentage of penetration T% (Transmittance %). The abscissa is the spectral wavelength (in nm). Other parameters are (1) white light environment, (2) incident angle (twist), and (3) reference wavelength is 55 〇 nm. The transmittance T% in the visible light (400 nm to 700 nm) portion is on average about 20%. The transmittance T% in the infrared (780 nm to 1,000 nm) portion is between 95% and 96% on average. In thin film optics, we can easily achieve a desired transmittance T% by multi-layer quarter-wave film stacks with high refractive index changes by optical method or admittance trajectory method on optical grade substrates. Please refer to the flowchart of the implementation method of the device. The implementation method of the device is exemplified by the learning of the Chinese phonetic symbols for Chinese and the green positive method: (1) An imaging mirror 30 is provided. The imaging mirror 30 includes the fabrication of the coating mirror 31 and the formation of an imaging mirror 30 after completion of the coating mirror 31, as shown in FIG. The ambient illuminance of the classroom or correction room is calculated by the illuminance meter to be about 3 〇〇 Lux. The reflectance of the coated mirror 31 is about 80% from the spectrum of Fig. 7 23 201039291. Therefore, about 24 〇Lux (300Lux*80%) illuminance is reflected, and the illuminance reflection of the 240Lux causes the surface of the chain mirror 31 to present a bright mirror surface like a normal plane mirror 13. The lens 32a of the color camera 32 in the imaging mirror 30 has a transmittance of about 20% in the coated mirror 31 from the spectrum of Fig. 7. Therefore, in the classroom, about 6 〇 Lux (300 Lux* 20%) of the amount of light entering, as described above, the minimum ambient illuminance of the color camera 32, such as the minimum illumination limit of lLux, the amount of light entering the 6 〇 Lux is sufficient for the color camera 32. It can be imaged (a clear image of the former learner 12 and a mentor u can be taken to the coated mirror 31). (2) First, a learner 12 and an instructor 11 sit in front of the chain mirror 31, and both face the coated mirror 31 and a microphone 341 together. This is a one-to-one teaching method. Both the learner 12 and the instructor 11 face the coated mirror 31 to avoid face-to-face embarrassment. Through the reflection of the bright mirror surface on the coating mirror 31, both the learner 12 and the instructor can see the mirror images of both sides or the other party, and adjust the position of both the seats or the imaging mirror 30 if they are not completely visible. The coating mirror 31 in the embodiment is formed in a rectangular parallelepiped shape to at least display a mirror image of both sides. For example, a surface area of 40 cm in width and 25 cm in length, the mirror surface should be planar, and the plane shape is similar to that of the general plane mirror 13. If the curvature is too large, the mirror will affect the relative deformation of the lip. If the imaging mirror 30 is not placed on the tabletop but suspended from the wall, the seat with adjustable seat height should be purchased to accommodate other learners 121 of different body shapes. (3) As shown in 囷4: First, the instructor 11 speaks “丫”, and the learner 12 follows the opening and says “丫”. At this time, the learner 12 can see the instructor 11 a through the reflection of the coating mirror 31. The mouth shape action, followed by the opening imitation. The instructor also sees through the reflection of the coating mirror 31 whether the mouth shape of the learner 12b is correct or not? Because of the 丫, I, 廿, 廿 pronunciation features of Chinese national phonetic symbols, it is necessary to first locate the mouth and then pronounce it, and then stop the vocalization and then combine the mouth shape. You can't read your mouth while you are talking. (4) The instructor 11 looks through the reflection of the coating mirror 31 to see if the learner 12's mouth shape 12a has the first positioning mouth shape and then pronounces it? If you see that the learner's 12 mouth type 12a is 24 201039291 "When you read one side and put your mouth together," the instructor 11 should correct the situation on the spot and ask the learner 12 to face the coated mirror 31 and practice again. If the correction result is correct, continue to be followed by the instructor 11 for I, death, and gan, and also through the reflection of the coating mirror 31, to see if the image 12a of the learner 12 has the first macro-type re-pronunciation.疋 再 再 再 再 再 再 再 再 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Then accept the "one" sound. At this time, the learner 12 sees through the reflection of the keyhole mirror 31, and sees that the instructor 1 la mouth is opened and flat, and then receives a "one" sound, so that the mouth is pronounced, and the mouth shape is also opened and flat, and then the "recharge" One sound. At the same time, the instructor 11 also sees that the learner 12 changes the mirror image 12a of the mouth shape through the reflection of the coating mirror 31, and if there is an error in the pronunciation process, the correction is given again. The word 'Qiao' is more difficult to pronounce than the word "丫". The instructor 11 should observe the mouth shape of the learner 12 and also listen to the pitch of the pronunciation. If there is an error, correct it until the corrected pronunciation is correct. If the class ends, the class ends, otherwise continue. In order to reduce the burden of learner 12 learning, give appropriate rest. Furthermore, the pronunciation of the words "4" and "厶" is a Chinese phonetic symbol that learners 12 (especially children) are not easy to learn. In general, it is easier for learners to read "V" than to read "厶". This is mainly because: the southerner's pronunciation habit is that the "oral" is less open, so the mouth is smaller when the sound is "b". It is not difficult to read the nasal sound beforehand. However, the difficulty of the hair is getting louder, because the sound of the sound of "厶" is to be opened, and the "snap" is the post-nasal sound, which is close to the throat, because the Minnan language has a small tongue and a small mouth, and It is more difficult to use the voice of the South to make the sound of "skull". The instructor 11 can first transmit a "4" sound through the mirror reflection of the coating mirror 31. When teaching "Bu", tell the learner that the "Bu" looks like the mouth is "opened". When we read it, we must also open our mouths, that is, when we read 4, the mouth is open. Don't put it together, so you can learn it. Then try it again (open it, read it, and then finish it), and then practice immediately. 25 201039291 Xi Pin, Nüwa, 厶, 匚厶, 厶, 六厶's Pinyin practice. The foregoing flow (1) to (4) can be said to "display" the user's "reflection" image on the coated mirror 31. The latter (5) to (8) belong to the method of "ingesting" the user to "penetrate" the image on the color camera 32. (5) Next, if there is some difficulty in the follow-up and repetition of the learner 12, or if there is a difficult learning and correction method in the Chinese phonetic symbols of Chinese, then it is necessary to increase the color camera 32. Photography and recording functions are used to assist. Before the instructor 11 activates the color camera 32, it is often necessary to pass the consent of the learner 12 to avoid unnecessary trouble. For example, if there are 12 foreign learners in the language center of the university, the issue of whether the photography involves privacy rights should be respected. However, facial nerve treatment and correction, or language barriers for medical research centers are often subject to discretion. The instructor 11 can utilize the control box 34 to control the activation of the color camera 32, at which time the indicator light having the color camera 32 enabled in the control box 34 is illuminated (informing that the color camera 32 is enabled). In the control box 34, when the color camera 32 is enabled, the microphone 341 and its recording function can be simultaneously activated to achieve synchronization of video and audio. Ο After the color camera 32 is enabled, 'If you can't judge whether the mouth shape you want to ingest (for example, the learner 12, the learner 12 and the instructor 11, or the instructor 13) is all in the image capturing range, then The instructor 11 can view it from the image display 36. The image display 36 can be a palm-sized type (for example, a display having a 5-inch LCD screen) to facilitate the instructor 11 to view first, or a larger type (for example, a display having a 7-inch LCD screen) to facilitate the instructor; The learner 12 and two people look at it. If necessary, you can also project a projector to project the image, so that more learners can learn. The instructor 11 looks at the image display 36. If it is necessary to make a clearer view of the movement and position of the tongue in the mouth, the lens of the telescopic focusing function attached to the color camera 32 can be used to give the enlarged image to the part to be viewed. . (6) Check whether the mouth-shaped movements to be ingested fall into the image capturing range, and avoid the necessary images of 26 201039291. Then, the video access device 35 is enabled to store the "ingested" image and the recorded sound on the computer 32. It is difficult to learn Chinese phonetic symbols in Chinese, for example: 勹3 (the neck of the child) will be pronounced as a long sound of 勹t-one stone. Such "pinyin" has always been the hardest part of teaching the phonetic. Children (Learner 12) Pinyin often occurs in two ways: The first is to read the above sounds, and also to read the following rhymes, but read the sounds that are not put together. The second is to read the initials of the initials (that is, the rhymes of the pronunciation of the accent), in fact, the straight spelling method is straight) and 3 spells, there will be no dead sounds. The instructor 11 passes through the mirror reflection of the coating mirror 31, and the instructor "teaches the learner 12 to read the sound. The mouth is to be opened and rounded. If there are other learners in the classroom, 121 in the same course, the instructor 1; It is possible to compare the learner 12 with the short-term process, by externally connecting a large image display 36 or by projecting the projector's image output (AV output) onto the large screen to make more Other learners 121 use it to study while watching, so that his learner 121 is like learning in the same class. (7) Some pronunciation sounds are the function of blocking gas, mainly by blocking the air flow by lips, teeth and tongue. It is important to make learners 12 more aware of the correct pronunciation of a single word by clear and correct pronunciation. In particular, let the learner 12 know "what is wrong?" and "how to correct?" In the teaching process, if the learner 12 was found to follow up many times of opening, reading pronunciation and imitation, he always made a repeated mistake, and no significant improvement was found. Or the mentor 11 thinks it is necessary. At this time, the instructor U can enable the video access device 35 to record the video that is always repeating the mistake. The video access device 35 has two functions: one is to image the image captured by the color camera 32, including the instructor 11 teaching the progress and correction process of the learner', and then can be repeated and played at different speeds. Among them, 'slow speed playback is a step for observing "Where is the error?" and finding out "how to correct it." 27 201039291 The second is to read the image data stored in the image memory (for example, other schools or foreign countries also use the practice and correction of the image files stored in the home database);

(8) After the video of the repeated error is always recorded, the video playback device 35 is used for slow speed replay, for example, at a speed of 1/2 or 1/4. If necessary, a certain stage of slow speed playback is given to Pause or paused play, so that the instructor 11 clearly indicates on the video display display 36 that the learner 12 has the above two types of pinyin errors. Point out the wrong mouth shape and then teach the corrective method to indicate the appropriate steps, and then ask the learner to learn until the correction result is satisfactory. The above-mentioned mouth shape displayed by the image display unit 36 can be gradually compared with the standard pronunciation 发行 (such as 囷二B) issued by the educational unit or the expert system. (9) The above-mentioned captured audio and video is given to the video recording archive through the audio-visual access device 35 for additional value added to the method. For the final analysis and correction results, store them in the database of the expert system, so that those who need it from all over the world can learn and correct this kind of “display” and “record” through the remote end (for example, the upper cut technology network).
