     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0013]    Some embodiments of the present invention are described in details below. However, in addition to the descriptions given below, the present invention can be applicable to other embodiments, and the scope of the present invention is not limited by such, rather by the scope of the claims. Moreover, for better understanding and clarity of the description, some components in the drawings may not necessary be drawn to scale, in which some may be exaggerated relative to others, and irrelevant parts are omitted. 
         [0014]    Please refer to  FIG. 1 , the present invention discloses an electronic device  100  for zooming in image, including a touch screen  110  and a processor  120 , wherein the touch screen  110  displays an image. The processor  120  identifies the proximity or the touch of an object  150  to generate the pointer  140  on the touch screen  110 . When single object  150  touch the touch screen  110  so as to generate a touch signal, the pointer  140  is placed at the position of the wave crest of the touch signal, but it is unnecessary to display the pointer  140  on the touch screen  110  (as shown in  FIG. 3 , FIG,  4  and  FIG. 5 ). 
         [0015]    Please refer to  FIG. 2 , while another one object  152  approaches the previous object  150 , and the adjacent two objects  150 ,  152  touch the touch screen together to generate a touch signal, the pointer  140  is still placed at the position of the wave crest of the touch signal. It is unnecessary to display the pointer  140  on the touch screen  110  (as shown in  FIG. 3 , FIG,  4  and  FIG. 5 ). 
         [0016]    Please refer to  FIG. 3 , when the processor  120  identifies the another one object  152  approaching the object  150 , the processor  120  controls that the touch screen  110  zooms in a partial image  132 , which is the image  130  placed partially within a predetermined range  142  around the pointer  140 . In other words, the processor  120  identifies the proximity or the touch of the object  150  to generate the pointer  140  on the touch screen  110 . Then, the processor  120  controls the touch screen  110  to zoom in the partial image  132  while identifying the another one object  152  approaching the object  150 . The pointer  140  is located at the center of the predetermined range  142 , and the circumference of the predetermined range is formed by a predetermined radius. 
         [0017]    Please refer to  FIG. 3  again, when the adjacent two objects  150 ,  152  touch or the object (one of the adjacent two objects  150 ,  152 ) touches the partial image  132  on the touch screen  110  to generate a touch signal after the partial image  132  appears, the processor  120  generates a command of clicking on a clicked position (such as the position of the pointer  140  as shown in  FIG. 1 ) on the partial image  132 , wherein the clicked position on the partial image  132  is mapping to a position on the image  130  partially within the predetermined range  142 . For example, when the pointer  140  is located at a scroll bar of a window, and the partial image  132  is generated, the partial image  132  is the partial scrollbar of the window. When the adjacent two objects  150 ,  152  touch or one of the adjacent two objects  150 ,  152  touches the position of scrolling down the window on the partially magnifying image to generate a touch signal, the processor generates a command of clicking on the clicked position (the command of scrolling down the window), wherein the actually clicked position of the touch screen  110  is a position of the real image  130 , which is partially within the predetermined range  142 , mapping to the position of the pointer  140  on the partially magnifying image of the scrollbar of the window. 
         [0018]    Furthermore, please refer to  FIG. 3 , when the adjacent two objects  150 ,  152  touch or the object (one of the adjacent two objects  150 ,  152 ) touches the partial image  132  on the touch screen  110  to generate a touch signal after the partial image  132  appears, the processor  120  generates a command of clicking on a clicked icon on the partial image  132 , wherein the clicked icon on the partial image  132  is mapping to an icon on the image  130  partially within the predetermined range  142 . For example, when the pointer  140  is located at a dialing icon (upper section of the image  130  or the lower section of the image  130 ), and the partial image  132  is generated simultaneously, the partial image  132  is the dialing icon. When the adjacent two objects  150 ,  152  touch or one of the adjacent two objects  150 ,  152  touches the dialing icon on the partially magnifying image to generate a touch signal, the processor  120  generates a command of clicking on the clicked icon (the command of dialing), wherein the actually clicked icon of the touch screen  110  is the real dialing icon, which is partially within the predetermined range  142 , mapping to the partially magnifying image of dialing icon. 
         [0019]    Please refer to  FIG. 3  and  FIG. 4 , when the pointer  140  (or the objects  150 ,  152 ) is moving, the predetermined range  142  is moving with the pointer  140  to simultaneously zoom in the image partially within the moving predetermined range  142 . 
         [0020]    Please refer to  FIG. 5 , when the touch screen  110  detects the disappear of at least one of the two objects  150 ,  152 , for example, the object  152  leaves the touch screen  110 , the partial image  132  is still zoomed in through a predetermined duration. Please refer to  FIG. 6 , when the pointer disappears, for example, both objects  150 ,  152  leave the touch screen  110 , the partial image  132  is still zoomed in through a predetermined duration. In other words, when one or both of the objects  150 ,  152  disappear, the partial image  132  is still zoomed in so that a user could still click on the partial image  132 . 
         [0021]    Accordingly, the present invention discloses a method for zooming in image, including the following steps. Please refer to  FIG. 7 , at first, in step  200 , the proximity or the touch of an object on a touch screen is identified to generate a pointer on the touch screen. Next, in step  210 , after identifying another object approaching the object, a partial image, which is an image placed partially within a predetermined range around the pointer, is zoomed in. While the adjacent two objects touch the touch screen to generate the touch signal, the object is located at the position of the wave crest of a touch signal. The center of the predetermined range is the position of the pointer, and the circumference of the predetermined range is formed by a predetermined radius. 
         [0022]    Then, in step  220 , when the adjacent two objects touch or the object touches the partial image on the touch screen to generate a touch signal, a command of clicking on a clicked position on the partial image is generated, wherein the clicked position on the partial image is mapping to a position on the image partially within the predetermined range. 
         [0023]    Or, in step  230 , when the adjacent two objects touch or the object touches the partial image on the touch screen to generate a touch signal, a command of clicking on a clicked icon on the partial image is generated, wherein the clicked icon on the partial image is mapping to an icon on the image partially within the predetermined range. 
         [0024]    After step  210 , when the touch screen detects the disappear of at least one of the two objects, the partial image is still zoomed in through a predetermined duration, as shown in step  240 . Or, after step  210 , when the touch screen detects the disappear of the object, the partial image is still zoomed in through a predetermined duration, as shown in step  250 . 
         [0025]    After step  210 , when the pointer is moving, the predetermined range is moving with the pointer to simultaneously zoom in the image partially within the moving predetermined range, as shown in step  260 . 
         [0026]    The above embodiments are only used to illustrate the principles of the present invention, and they should not be construed as to limit the present invention in any way. The above embodiments can be modified by those with ordinary skill in the art without departing from the scope of the present invention as defined in the following appended claims.
