Description of the Invention: [Technical Field] The present invention relates to an image scaling technique, and more particularly to an electronic device and a method for adjusting the aspect ratio thereof. [Previous technology with touch screen] At present, touch screen technology has become more and more popular, because its functions are diversified and the price is gradually decreasing. The job screen allows you to use the zoom-in or file browsing of the two-page webpage, for example, Ping 9 · The iPhone of the wood is used to realize the enlargement or reduction of the webpage or the file. It is necessary for people who are not comfortable with the finger. This function is difficult to operate. (10) The two fingers are solid. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide an electronic device with a touch screen. The operation of the μ is simpler. It is necessary to provide a method for adjusting the aspect ratio of the screen with simpler operation, including the following steps. : recording a circle track generated by the user's loop operation on the touch screen, detecting a circled area surrounded by the circled track; calculating a proportional relationship between the circle area and the preset area; and displaying the display according to the proportional relationship Proportional adjustment - A method for adjusting the proportion of the face, including the following steps: Recording the user's operation on the touch screen昼 轨迹 · 检测 检测 检测 检测 检测 检测 检测 检测 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 2010 The electronic device with a touch screen includes a sensing unit for sensing a touch operation of the user to generate corresponding trajectory data, and the electronic device further includes: processing unit for detecting that the trajectory data is a closed area Calculating the area information of the area surrounded by the trajectory data; ❹ executing unit for proportionally adjusting the display screen according to the proportional relationship between the area information and the preset area. When using the above screen zoom method and an electronic device with a touch screen The user can zoom in or out on the selected area with a single finger loop operation, and the operation is simple and convenient. [Embodiment] Hu Feng #_ 4 proposes a kind of picture zooming method, which can be used according to the size of the two areas. Appropriate enlargement or reduction of the display face. /Ha method is applicable to various (four) touch settings For example, a mobile phone, a portable player, a digital camera, etc. As shown in FIG. 1 , it is a flow chart of a preferred embodiment, including the following steps: that is, the party (4) on the touch screen _^ Generate a circle track. Please refer to _ 2 and Figure 3, the touch screen ^ clockwise and counterclockwise circle operation generated by the circle of the user step S303, detect the gold surrounded by the circle to mark the book And the area of the circle. The area can be calculated by the number of pixel points included in the circle & field or the number of touch matrices 201009661. Step S305, detecting the circle of the circle counterclockwise. The direction of the circle is included Clockwise and clockwise. The 4 o'clock (four) hour hand corresponds to the image enlargement and reduction step S307, respectively, the ratio of the preset area of the m|product in the embodiment. ; 2 = The area is the display area of the touch screen, with -❸. Because it is better to achieve user needs
