In the figure, a screen 12 and an acoustic module 15 are displayed. Storage 椹 | 201122938 Station 4 information, for example, display panel information on screen 12 〗 4i, operating system and application %. The panel information (4) is obtained from the display extension display identification code (EDID) 121, and the panel information 乂 ^ 3 includes the panel size 142 of the panel length and width. The data computing module 11 executes the sequel to the user's device. After the system 16 is generated, a user interface image is generated, which is displayed on the screen 12 for the user to watch and further manipulate, for example, by The application interface executes the application W. The touch module 糸 detects whether there is a foreign object such as a stylus or a user's finger, and contacts the right side of the touch module 13 to output a touch signal 131 including the touch position 132. The judging module 15 determines whether to enlarge or display one of the images 111 displayed on the screen 12 according to the panel information 141 and the current system resolution 16. The operating system 16 can further set the display resolution by the user, and the operating system and system 16 are executed. A current system resolution 161 and a system maximum resolution 162 are recorded. In this embodiment, the determination module determines the current system resolution 161 from the operating system 16. Since the user can set the display resolution 自行, and the + display resolution is the same as the display of the graphic material on the display screen 12, the total area of the display 2 is displayed, so that the group 15 can be determined according to The panel information 141 and the current system resolution i6i are determined whether or not the image 111 needs to be enlarged. The judging module i 5 can calculate a panel per point value (DPI) 153 according to the board information 141 and the panel maximum resolution 143, for example, the length or width of the panel maximum resolution 143. Divided by the length or width corresponding to the panel size 142, as shown in Table 1 below, it includes a plurality of panel sizes 14; and a panel DPI value corresponding to the panel maximum resolution 143. In the same manner, the judging module 15 first calculates a system DPI 152 based on the panel information 141 and the current system resolution 161. Next, the determination module 15 compares the system DPI 152 with the panel DPI 153. The higher the DPI, the larger the touchable area on the panel. As shown in Table 2, it records the touchable size of different DPIs on different size panels. The larger the DPI value, the more touchable. The larger the area, so when the judging module 15 judges that the system DPI 152 is smaller than the panel DPI 153, it indicates that the image 111 needs to be enlarged. Therefore, the data operation module 11 enlarges the image 111 based on the determination result 151 of the determination module φ 15. Panel Size System Maximum Resolution Panel DPI 18 吋 Panel (16.1*9.07 inch) 1920x1080 (Default) 119 15 吋 Panel (13.5*7.6inch) 1366x768 (Default) 101 11 吋 Panel (10.1*5.7 inch) 1366x768 (Default) 135 DPI 11 11 panel 15 panel 18 panel 96 0.608cm 0.8 cm 0.704 cm 120 0.76 cm 1 cm 0.88 cm 144 0.912 cm 1.2 cm 1.056 cm 192 1.216 cm 201122938 In the implementation of the 'magnified image (1) is better to display the screen The image displayed in the corresponding area of the touch position is as shown in Fig. 2. In the figure (4), when the user touches the screen, the touch position of the touch signal (3) is £132. Therefore, if it is judged that the module needs to enlarge the image, the data operation module U enlarges the image 111 of a preset area around the touch position £132, and displays the enlarged image in the area 211, as shown in the figure ( B), so the user can see more clearly. Among them, the judgment module 15 can determine the magnification of the image in according to the system DPI and the panel DPI as needed. Wherein, the enlarged image area 2 ΐ ι can be added with a close button icon 22 for the user to manually end the image enlargement function. Referring to Figure 3, there is shown a block diagram of a second embodiment of the computer system of the present invention. In the figure, the second embodiment is different from the first embodiment in that 'when the user launches the application 37 in the operating system 16, the application 37 generates an operation interface to be displayed on the display screen 12' and The application 37 is information of one of the interface areas 371 of the recording operation interface and a zoom level 372 (ζ〇〇ιη leVel) within the operation interface. The interface area 371 preferably includes an interface position and an interface size. The application 37 is preferably a web browsing application. Most web browsing applications also let users scale the text or photos within the operating interface. Therefore, if the application 37 adjusts to enlarge the text or photos in its operation interface, the computer system of the present invention can eliminate the need for image enlargement to avoid user confusion. Therefore, the judging module 15 is configured to calculate the system DPI 152 and determine whether the touch position 132 is located in the interface area 371 of the application 37. When it is determined that the 201122938 touch position 132 is located in the interface area 371, the judging module 15 obtains the interface area 371. The level 372 is scaled and it is determined whether the image is enlarged based on the zoom level and the system DPI 152. In practice, the determination module 15 can perform the above comparison using a lookup table, as shown in the following table 3, which records the Dpi value corresponding to the different zoom level 372. The judging module 15 firstly finds the DPI corresponding to the zoom level 372 from the first table. When the DPI corresponding to the zoom level 372 is less than or equal to the system Dpi 152, the judging module 15 notifies the data computing module 11 to enlarge the image. _: zoom level DPI zoom level ΠΡΤ _______96 100% 144 XJ 125% ±U\J /0 a 200% Table 3 does not use ηί The judgment module in the embodiment makes the rhyme image of the 是 (4) amplification mechanism, as needed Can be combined to achieve the desired effect. (4) Clearing mechanism Please refer to Fig. 4, which is a private diagram of the present invention. In the figure, the method includes the following steps: the touch of the touched position is less than A1, and when the touch-touch is performed, the touch screen is produced by the touch screen == for example - foreign object touch No. for the back-end device to touch the detection board according to this touch ^, the system resolution and the display screen 11 201122938 曰 In step A3, judge according to the panel information and the current system resolution, or not Displays one of the images displayed on the screen, such as an image that touches the area adjacent to the location. The user only needs the function of image placement = when the face is too small, so the judgment is made in step A3. For example, the value per inch of the system can be calculated according to the panel $Xiantian system resolution and the maximum resolution of the system ( Dot per inch, DPI) and panel DPI, and judge whether to enlarge the image according to the two values; or, if the user touches the program interface with zoom function (Z00m jn/〇ut), it can be based on The system DPI and the zoom level of the interface (z〇〇m level) are used to determine. In step A4, the image is selectively enlarged according to the judgment result. If the result of the determination in step A3 is that magnification is required, the image of a specific position on the face is enlarged, for example, the image adjacent to the touch position is enlarged. In addition, the magnification may be determined according to the system DPI and the panel Dn; or the magnification may be determined according to the zoom level and the system DPI. Referring to Fig. 5, there is shown a flow chart of a first embodiment of the image enlargement method of the present invention. In the figure, this embodiment corresponds to the computer system shown in the figure, and includes the following steps. In step B1, a current system resolution 161 degrees and a system maximum resolution 162 are obtained from the operating system 16 in execution, and the panel size 142 is read from the extended display identification code 121 of the display screen 12. In step B2, a system Dpil 52 and a panel DPI 153 are calculated. In step B3, it is detected that there is a foreign object touching the touch module 13. In the implementation, whether the touch detection signal 131 or the touch detection signal 131 from the touch module 13 is included in the touch detection module 131 may be included in the above manner. When it is detected that a foreign object touches the touch module 13, step B4 is performed; otherwise, 12 201122938 'step B6 is executed. The system DPI 152 and the panel DPI 153 are compared at step B4, 'determining whether the system DPI 152 is smaller than the panel DPI 153. If yes, it means that you need to enlarge the image, go to step B5; if no, it means you don't need to enlarge the image, go to step B3. In step B5, the image of the area around the touch position 132 is enlarged, as shown in FIG. In step B6, when it is detected that no foreign object touches the touch module 13, it is determined whether or not the image is enlarged. If not, go to step B3; if there is, execute step B7 to delay the preset image and resume with the enlarged image. After the user touches the touch module 13 to enlarge the image and obtain the desired information, the user only needs to remove the foreign object touching the touch module 13, and the computer system will be after a preset time. Restore the image. Please refer to FIG. 6, which is a flow chart of the steps of the second embodiment of the image enlargement method of the present invention. In the figure, the present embodiment corresponds to the computer system shown in Fig. 3, and includes the following steps, which are performed from the initial steps. In step C1, it is detected whether a foreign object touches the touch module 13, and if so, step C2 is performed; if not, step C3 is performed. In step C2, the computer system executes a determination mechanism to determine whether to enlarge the image, and if so, enlarges the image of the area around the touch position in step C3; if not, returns to the start step. The detailed steps in step C2 will be explained later. After the image is enlarged, it is determined in step C41 whether the foreign object releases the touch module and then touches other positions of the touch module. If yes, step C42 is performed; if not, the process returns to the start step. When the foreign object touches the other position of the touch module, it means that the user may touch the button or the link in the enlarged image; or use 13 201122938 to operate the content of other areas, whether the button is touched Or the link, if yes, proceed to step J to disconnect the foreign object corresponding to the button % p V C5 to execute the phase picking program, and then return to the starting step; if not, the second step C43 determines whether the zoom is touched: 4 = :: Close button 22' If no, go back to the beginning. After the image is restored, the image is restored to the start step. Please refer to FIG. 7 for a flowchart of the implementation of the present judgment mechanism. In the picture:: Do not zoom in on the itch 铱T This step of the judgment mechanism D1 In Liu, Cl, in step D1 to determine whether the touch position is the zoom level of the program, the pass is enough to etch ίί, right 疋, indicating that the zoom level of the current browsing program needs to be enlarged, clearly viewed, and does not need to enlarge the image; the shirt indicates that the shirt image is to be enlarged, and step C3 in FIG. 6 is performed. In the step D1, the touch position is not in the interface area of the (4) program, + the execution step D4 is calculated - the system DPI and the panel DPI, = in step D5, it is judged whether the system DPI is smaller than the panel 〇ρι, if the step C3 is executed Zoom in on the image, and if not, go back to the start step. The above description is only for the purpose of the genus, and the material (4) ° is not removed from the spirit of the moon and the equivalent modifications or variations to be included in the scope of the appended patent application.
