Action Ranged In the preferred embodiment, the moving block calculation unit 131 transmits a motion estimation and motion compensation (MEMC) algorithm according to the first Each image plane in the image frame group and an image adjacent to the image plane are written to obtain at least one pair of moving blocks corresponding to the image frame, and the teaching activity range is calculated from the moving block; Each teaching activity ranges from a set of the moving blocks corresponding to one of the image frames of the first image group, and each teaching activity range has a plurality of pixels (Pixel). The motion estimation and motion compensation algorithm can be easily understood by those skilled in the art, and therefore will not be described here. The mobile block calculation unit has m~μ布-彩1豕ϊ, melon - an image frame, at least - a moving block corresponding to the image plane, and a user activity range obtained according to the moving block of each image frame. In the preferred embodiment, the moving block calculation unit 131 And the motion estimation algorithm and the motion compensation algorithm are further configured to obtain, according to each image frame in the second image mask group and an image plane adjacent to the image frame, at least a moving block corresponding to the image frame, And calculating the user activity from the mobile block to Ge. Ganzi. Leganwei, wherein the parent-user activity range is 9 201227632, and the image frames of the first image group of S Hai are One of the set of moving blocks' and each user activity range has a plurality of pixels. The analyzing unit 132 is configured to obtain a majority according to the range of teaching activities and the user/tongue range a difference range (Difference Range) for generating a multimedia output signal reflecting the degree of difference between the teaching video and the instant activity video according to the difference range; in the preferred embodiment The multimedia output signal has at least one of a visual effect and an audible effect. wherein the difference ranges are the pixels and the user activity of the teaching activity range on the same time axis by the analyzing unit 132. The result of the comparison is performed by the pixels of the range. The analysis unit 132 further generates a corresponding teaching activity signal and a user activity signal according to the range of the teaching activities and the range of the user activities. The multimedia output signal includes the teaching activity signal and the user activity signal, wherein the teaching activity signal corresponds to a teaching activity range, and the user activity signal corresponds to a user activity range, and the content of the user activity may reflect the teaching video and the instant activity video I Different degrees. When the teaching activity signal and the user activity signal φ are output by the video output module 151, the user can see the corresponding teaching activity range and the user activity range. When the user selects the "second mode" through the user operation interface 14, the output unit 15 is configured to receive and output the teaching video, and 誃 > media output signal. ° Continuing the above example, as shown in item 3, in the second mode, the user can simultaneously see the 10 201227632 P image of the teaching video through the video output module 151, corresponding to the image plane 6 The scope of the teaching activity 8, '" user activity range 82, and the range of the difference 81. Therefore, in addition to being able to learn according to the teaching video, the user can clearly see what is not the result of the recording video. The teaching 'gluent range 8' overlaps with the user activity range 82 at least partially. The continuation of the above example, in the second mode, the analysis unit 132 may/are for each of the teaching activity range 8, the user movement range 82' and the difference range 81 corresponding to the image frame 6. The pixels are given different primary color (RGB c〇1〇r) values. For example, the primary color values of all the pixels of the teaching activity range 8 are red. The three primary color values of all the pixels of the user activity (four) are green. The three primary color values of all the pixels of the difference range 81 are blue. The visual effect includes the three primary color values of the difference range. Therefore, the user can easily distinguish between the wrong actions and the different parts through different colors. In addition, the multimedia output signal has an audible effect produced by the analysis list & 132 in addition to the visual effect reflecting the degree of difference between the teaching video and the instant activity video. The audible effect indicates that the user has an error (4). That is to say, the user can also realize that it is necessary to adjust his own motion through the audible effect output by the audio output module 152. Continuing the above example, in the second mode, if the teaching activity range 8 is completely equal to the user activity range 82, the analysis sheet a 132 does not generate the auditory effect.

In other words, the analyzing unit 132 analyzes the range of the teaching activity generated at the same time point and the range of the user activity to obtain the corresponding difference information, wherein the analyzing unit 132 determines the difference. The range has a ratio of the total number of the pixels to the total pixels of the teaching activity range as the difference information; the analyzing unit 132 generates an evaluation value according to each difference information and referring to a preset threshold value. And the evaluation value is π to record; "The analysis #& 132 then averages the evaluation values to obtain a comprehensive value, wherein the comprehensive value represents the evaluation of the performance of the user during the learning process. fraction. The multimedia output signal also includes a picture for the integrated value display. Finally, the user can output the multimedia signal by the video output module 151 to know the learning status of the user, wherein the evaluation value and the comprehensive value range from 1 to 1 and up to 100. . In the preferred embodiment, the threshold value may be preset by the user through the user operation interface 14, and may be a first threshold value, a second threshold value, and an - i th threshold value. A trip. For example, assume that the first threshold, the second threshold, and the third threshold respectively represent a ratio of 4〇%, 2〇%, 〇%. If the threshold is the first threshold of 2012 201232 (40%), the evaluation value generated when the difference information is less than 40% is "100 points". If the threshold is the second threshold (20%), the evaluation value produced when the difference information is less than 20% is "100 points". If the threshold is the third threshold (〇%) ′, then the total range of the pixels that the difference range has must be 0, and the generated evaluation value will be “10〇”. Further, in the third mode, if the analysis unit 132 refers to the first critical value, and when the difference information is 27%, the generated evaluation value is "100 points" (ie, 100_27+). 40). If the analysis unit 132 refers to the second threshold, and when the difference information is 27%, the resulting evaluation value is "93 points" (i.e., 100-27+20). If the analysis unit U2 refers to the third critical value, and when the difference information is 27%, the evaluation value produced is "73 points" (i.e., ioo-27+o). Continuing the above example, as shown in FIG. 4, it is assumed that the second threshold value is referenced by the analyzing unit 132, and five sets of evaluation values are generated as "6 points", "7 points", "80 points", "90 points" and "1 points", finally the user sees through the video output module 丨5丨 a picture 9 showing the integrated value (ie, "80 points"). In summary, the interactive multimedia teaching device of the present invention not only allows the user to simultaneously view the teaching video and the live event video, but further proceeds to 'produce the output generated by the video analysis system 13 The multimedia output signal enables the user to clearly know whether his or her actions are related to the teaching video, and even to further understand why the part is not being improved, and to improve the learning (four) quantity and efficiency. It is indeed possible to achieve the object of the invention. 13 201227632 The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent change of the patent application scope and the description of the invention is Modifications are still within the scope of the invention.
