     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to a computer device and, more particularly, to a computer device for providing a stereoscopic image. 
     2. Description of the Related Art 
     In recent years, a display technology gradually becomes mature. At the same time, a rapid developing display technology is a stereoscopic image display technology. The stereoscopic image display technology is a display technology which can provide stereoscopic images with a three dimensional (3D) effect. 
     The stereoscopic image display technology utilizes a binocular disparity property of human eyes to allow a user to have a 3D feel when he or she watches a processed stereoscopic image. For example, the user can wear a pair of special two-color glasses to watch the stereoscopic image composing of a green image and a red image to feel the stereoscopic image with the stereoscopic effect. Furthermore, a user can utilize a projector to project two images on a screen and stack two polarizers in front of the projector. Consequently, once the user wear a pair of polarizing stereoscopic glasses whose left and right glasses have different angles, the user can see a stereoscopic image with the stereoscopic effect. 
     However, if the stereoscopic image with the stereoscopic effect is provided in the above ways, the user needs to wear a pair of special stereoscopic glasses. Additionally, the cost of the polarizing stereoscopic glasses and the projector is expensive, the user needs to go to a special place (such as a cinema) to watch the stereoscopic image with the stereoscopic effect. As a result, it is not convenience for the user.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
       FIG. 1  is a block diagram showing a computer device  100  for providing a stereoscopic image according to a first embodiment of the invention. The computer device  100  can be used for providing a stereoscopic image Im 3 D. The computer device  100  includes a host  120 , a display  140 , and a stereoscopic display film  160 . 
     The host  120  is used for reading the image data D 3   d  having 3D information. The display  140  is connected with the host  120 . The display  140  is used for displaying an image Im converted from the image data D 3   d.  The display  140  has a fixing element  142 . 
     The stereoscopic display film  160  is detachably fixed at a front side of the display  140  via the fixing element  142 . The front side of the display  140  is a side used for displaying the image Im. The stereoscopic display film  160  disposed at the front side of the display  140  can be attached on the display  140 . Consequently, the image Im can be converted to the stereoscopic image Im 3 D with the stereoscopic effect via the stereoscopic display film  160 . 
     Additionally, a processing system  122  is provided in the host  120 . The processing system  122  is used for converting two-dimensional (2D) image data to the image data D 3   d  having the 3D information. In this usage, the image data D 3   d  converted by the processing system  122  is corresponding to the stereoscopic display film  160 . As a result, the image Im can be converted to the stereoscopic image Im 3 D having the stereoscopic effect via the stereoscopic display film  160 . 
     The disposition of components of the computer device  100  and how the image data D 3   d  is corresponding to the stereoscopic display film  160  are explained in the following example.  FIG. 2  is a schematic diagram showing the computer device  100  in  FIG. 1  from a view angle according to an embodiment of the invention. In this embodiment, the host  120  can directly read a multiple-view stereoscopic image data from an external device or utilize the processing system  122  to convert the 2D image data to the multiple-view stereoscopic image data as the image data D 3   d  having the 3D information. Afterwards, the host  120  transmits the image data D 3   d  to the display  140  to allow the display  140  to display the image Im converted from the image data D 3   d.    
     In this embodiment, the stereoscopic display film  160  may be a lenticular lens. In practical usage, the thickness of the lenticular lens is about 0.3 microns to 3 microns. The image data D 3   d  having the 3D information is corresponding to the stereoscopic display film  160 , which means that the processing system  122  determines a converting mode to covert the 2D image data to the image data D 3   d  having the 3D information according to a property of the stereoscopic display film  160  (a structure of the lenticular lens such as a grid line number, a grid line distance, or a grid line direction). As a result, the processing system  122  can provide the image data D 3   d having the  3D information and corresponding to the stereoscopic display film  160  to allow the display  140  to display the image Im at a front side SD 0 . Afterwards, the image Im becomes the stereoscopic image Im 3 D via the stereoscopic display film  160 . Consequently, the user can see the stereoscopic image Im 3 D with the stereoscopic effect. 
     How the stereoscopic display film  160  is detachably fixed to the display  140  via the fixing element  142  is explained in the following example. In  FIG. 2 , when the multiple fixing element  142  are provided, that is, the display  140  includes multiple fasteners, such as fasteners A 1  and A 2 .

In this embodiment, since the computer device  100  has the fasteners A 1  and A 2 , when the stereoscopic display film  160  is at the front side SD 0  of the display  140 , the fasteners A 1  and A 2  are moved to the positions as shown in  FIG. 3A  to fix the stereoscopic display film  160  on the display  140 . Reversely, when the stereoscopic display film  160  needs to be detached, the fasteners A 1  and A 2  are moved to the positions as shown in  FIG. 3B . Afterwards, as shown in  FIG. 3C , the stereoscopic display film  160  can be detached from the display  140 . As a result, the stereoscopic display film  160  can be detachably fixed at the front side SD 0  of the display  140  via the fasteners A 1  and A 2 . 
     In the above embodiments, the stereoscopic display film  160  is detachably fixed at the front side SD 0  of the display  140  via the fasteners A 1  and A 2 . It is just for explaining the embodiment of the invention, but not for limiting the scope of the invention. Other fixing ways also may be used. For example, the stereoscopic display film  160  can be adhered on the display  140 , or the stereoscopic display film  160  can be suspended on the display  140 . As long as the stereoscopic display film  160  can be detachably fixed at the front side SD 0  of the display  140  via the fixing element  142  to produce the stereoscopic image Im 3 D with the stereoscopic effect, the fixing way is in the scope of the invention. 
     Additionally, after the stereoscopic display film  160  is detached form the display  140 , the stereoscopic display film  160  can be collected into the computer device  100 .  FIG. 4A  is a schematic diagram showing the computer device  100  in  FIG. 1  from another view angle according to another embodiment of the invention.

The back cover  144  is used for containing the stereoscopic display film  160  detached from the display  140 . Two runners are disposed at two sides of the back cover  144 , respectively. The two sides of the back cover  144  may be two sides SD 1  and SD 2  of the back cover  144  as shown in  FIG. 4A . The runner may be a runner SL as shown in  FIG. 4B . Consequently, the stereoscopic display film  160  can be contained in the back cover  144  via the runners SL at two sides SD 1  and SD 2  of the back cover  144 . 
     A cover plate A 3  may be disposed at the back of the display  140 . The cover plate A 3  is disposed at the back cover  144  and close to a side of the back cover such as a base side BL  144  in  FIG. 4A  and  FIG. 4B . The cover plate A 3  is used for fixing the stereoscopic display film  160  contained in the back cover  144  via the base side BL of the runner SL. As a result, after the stereoscopic display film  160  is detached from the front of the display  140 , it can be contained in the back cover  144  at the back of the display  140 . Thus, the stereoscopic display film  160  is collected in the computer device  100 . 
       FIGS. 5A˜5C  are exploded diagrams showing a process of containing the stereoscopic display film  160  into the back cover  144  of the display  140  according to an embodiment of the invention. The cover plate A 3  is moved to a position in which the stereoscopic display film  160  can be fastened to the runner SL. In the position of the cover plate A 3  as shown in  FIG. 5A , the stereoscopic display film  160  can be put in the back cover  144  via the runner SL. 
     Afterwards, as shown in  FIG. 5B , the stereoscopic display film  160  is put in the back cover  144  via the runners SL. After the stereoscopic display film  160  is all contained in the back cover  144 , the cover plate A 3  is moved to a position, such as the position of the cover plate A 3  as shown in  FIG. 5C , in which the stereoscopic display film  160  can be fixed. As a result, via the runner SL of the back cover  144  and the cover plate A 3 , the stereoscopic display film  160  can be contained in the back cover  144  of the display  140  and fixed. 
     Additionally, the stereoscopic display film  160  is contained in the display  140  via the back cover at back of the display  140 . It is just an example for explaining, but not for limiting the invention. In other usages, the stereoscopic display film  160  may be contained in other parts of the computer device  100 . For example, a back cover may be disposed at the back of the host  120  to contain the stereoscopic display film  160  detached from the display  140 . As long as the stereoscopic display film  160  can be detached from the front of the display  140  and contained in the computer device  100 , the way is in the scope of the invention. 
     The computer device  100  in the embodiments of the invention may be a notebook. When a user uses the computer device  100 , the stereoscopic image Im 3 D with the stereoscopic effect can be obtained by utilizing the host  120  to read the image data D 3   d  having the 3D information or executing software which can make the stereoscopic image data D 3   d  in the processing system  122 , and disposing the stereoscopic display film  160  at the front side SD 0  of the display  140 . As a result, via the computer device  100  which can provide the stereoscopic image, users may obtain the stereoscopic image with the stereoscopic effect conveniently and do not need to wear a pair of the special stereoscopic glasses, or go to a special place (such as a cinema) providing the stereoscopic images. Consequently, users may obtain the stereoscopic images more conveniently. Additionally, since they may obtain them more conveniently, the invention helps to popularize the computer device which can provide the stereoscopic image. 
     Via the stereoscopic display film detachably fixed to front of the display, when the host reads the image data having the 3D information, the computer device which can provide the stereoscopic image makes the display produce the stereoscopic image with the stereoscopic effect.
