For the viewer's eyes, the color of the background needs to be calculated, so the electronic device needs to be. Furthermore, the color of the text changes with the background color is quite uncomfortable. Therefore, how to correct and correct the subtitles of the new money, so that the text month has a more obvious and clear presentation, has become one of the problems that R & D personnel to solve. [Summary of the Invention] In addition to the above, the main purpose of this is to provide a subtitle text display device system, by knowing the average brightness value of a plurality of pixel points in the subtitle text display area to select the color of the subtitle. In order to make the text more sleek and clear, and through the shift processing of the text subtitles, two kinds of non-colors are used to display the text subtitles. a thief reveals the road - a subtitle text display method, which is a number of pixels corresponding to the subtitle text display in the background image of Na, the pixels are 'closed to display the text to be displayed in the subtitle file, including the following steps : Firstly, the '^ degree table' is created. This exemption table stores a plurality of brightness level intervals, and each brightness level interval corresponds to the first color and the second color. Then, the _ subtitle text shows the brightness scale of the pixel, and then the average brightness level is obtained according to each brightness level. The first color and the second color of the brightness quasi-health domain to which the average brightness level belongs are obtained from the brightness table. Wherein the first color and the second color are selected from different and high contrast colors. After that, the text to be displayed is based on the acquired first color and the second color, and the first color is displayed to generate the first color to be displayed and the second color to be displayed. And displaying a second color to be displayed; a position 'where the first position and the second position have a directional displacement (eg, upper, lower, upper left, upper right, lower left, or lower right) In the image of the outline scene: the screen text shows a number of images like the pro, these pixels are shown in the subtitles = waiting = text, _:, _ yuan, saki units and processing early including this unit (4) The measuring unit is used to calculate the brightness level table, and the brightness table stores a plurality of brightness level intervals, and the mother-level brightness level intervals correspond to the first color and the second color. After measuring the brightness level of the subtitle text display point, the average brightness level of the pixel points is calculated. The first color and the second color of the average brightness area of the button are said to be the first time and the second color. The unit will touch the text and follow the instructions. The color and the second color perform η to generate the first-color text to be displayed and the second color to display the text, the color to be displayed is displayed in the first position, and the second color is displayed in the second position. Where the first position and the second position have a directional displacement such as upper, lower, upper left, upper right, lower left or lower right.., etc.). The detailed features and advantages of the present invention are described in detail in the following detailed description of the embodiments of the present invention. The related objects and advantages of the present invention are readily understood by those skilled in the art. [Embodiment] In general, when playing multimedia videos using electronic devices (such as computers, TVs, mobile phones, electronic vocabulary, etc.), the screens that are played include image information, subtitles = inner valleys (for example, text symbols, English letters, etc.) and music sounds, while the inside of the subtitles and the display of the music sounds are based on the image information. However, the background image 2 疋 is formed by several pixels to form an image, and the content of the subtitle is displayed in the background image 2 the bottom. For example, when the background image 2 can be formed by pixels of 1 column to 3 columns, the content of the subtitle can be displayed at the pixel position of the column to column ' as shown in FIG. 1 The county's manual towel, the pixel point of the content display of the subtitle, is called the subtitle text display area 3. The specific embodiments are described below in order to explain the details of the present invention, and are illustrated by the accompanying drawings. The symbols mentioned in the description are referenced to the schematic symbols. Referring to "Pic 2" and "3", there is a brightness table in the database. The brightness table stores several exemptions. Each brightness level is like - the average brightness in the predetermined range is The specification has a corresponding first color and a second color (step 100). The first color and the second color need to be different colors, but are not limited to which color. The meaning of the color includes black, white, gray, red, blue or other kinds of colors. Then, the operation unit 30 randomly obtains the brightness level 28 (10) presented by the number of image points of the background image in the caption text display area 3 through the detecting unit 2, so that the unit 3〇 calculates the frequency point. Quiet level (transfer 8 1284291 m). The comparison unit 4G then queries the brightness table in the database 10 according to the average brightness level calculated by the operation unit 3G to obtain the brightness level interval corresponding to the brightness level, and the first color and the corresponding color brightness interval. b: color (step 120). Wherein, /, the processing unit 50 can further display the processing to be displayed in the subtitle text display area 3 according to the first color and the second color obtained by the comparing unit 4 to generate the first color to be displayed and The second color (step 130). Thereafter, the character to be displayed of the first color is displayed in the first position (step 140), the character to be displayed of the second color is displayed in the second position 1 (step 15〇), and the first position and the second position in the direction have the direction Displacement (eg upper, lower, upper left ^ upper right, lower left, lower right, etc.). Referring to Fig. 4, in the embodiment of the present invention, the money and brightness table includes a first-lighting solution and a second brightness level. The second system represents the average brightness level from "〇" to "127", which corresponds to the first color; ^ the first color is white; the second brightness threshold _ represents the average brightness level is "128" to 255", The corresponding first color is white and the second color is black. When the electronic device plays the button audio and video on the display unit (not shown), the brightness of the image is displayed on the background image 2 played by the random _ display unit in the early 20th. After the level is calculated, by calculating the average brightness level of the C3 image number, if the fine three image points are "2", "57" and "(10)", the average brightness level is "57". The unit 40 is queried from the brightness table according to the average brightness level "57" calculated by the operation unit 30, and is obtained from the brightness table to obtain the black (first color) and white (second color) corresponding to the first brightness level interval. . When the text to be displayed in the sub-screen text display area 3 is "dog to Wang", the processing unit 50 generates the black (first color) and white (second color) characters to be displayed after the "dog is coming". , the black "dog Wang Lai" is displayed to the position, and the white "dog Wang Lai" is to be displayed to the second position. In this embodiment, the second position is displaced to the upper right of the first position, as shown by the "figure 5". If the brightness level of the background image in the caption text display area 3 is calculated, the first color corresponding to the average brightness level is in the second brightness level interval, and the second color is black, such as The result shown in r Figure 6 shows 22〇. In addition, when the background image is a background of other colors in the caption text display area 3, for example, having a pattern or a twill or any background, the average brightness county can be calculated to fall within the first-light scale room or It is a second brightness level interval, which is a subtitle text method and a device provided by the invention according to the display result of "Fig. 7" and "Fig. 8", respectively. The average brightness value of several turns of several points selects the color of the text, and the text can be more simplified and clear through the movement of the Wencun screen, especially when it is seen from the distance.
