RELATED APPLICATIONS  
       [0001]    This application claims the benefit of Taiwan Patent Application No. 091111400, filed May 29, 2002, which is hereby incorporated by reference in its entirety. 
     
    
     
       FIELD OF INVENTION  
         [0002]    This invention is related to the means for displaying, especially related to the displaying means equipped with pluralities of memory card slots.  
         BACKGROUND  
         [0003]    As the popularity of digital image device increasing, it has become the trend to digitalize various images by using the digital camera or scanner. Moreover, users could share their photos or pictures through file transmission or Internet. Unlike usual camera or picture, the ordinary media is no longer necessary, and the limitation of space and time would not exist in the currency of images.  
           [0004]    However, since the digital image spreads quickly for the convenience of duplication and preservation, in general case, users still need personal computer (PC) or personal digital assistant (PDA) to display these images for appreciation. Otherwise, the images should be print on the papers or ordinary media. In this way, it is inconvenient.  
           [0005]    Besides, people like to place their beloved pictures in the frame and paste various paintings and posters on the wall as decorations. If users want to take the same disposition on any digital image, they must print it on papers. Moreover, if users want to mount some picture or painting with paste and hang it on the wall, they must print it on papers. Thus, there is nothing different from the situation before the digitalization of images. To such an innovative technology, it is indeed sarcasm and waste. This invention provides a means for displaying having pluralities of memory card slots, and has the capability to promote the convenience of the usage of digital images.  
           [0006]    The common storage device of digital images is the memory card. Its standards comprise not only the early compact flash card (CF card), smart media card (SM card), and multi media card (MM card), but also the newly memory stick card (MS card) and smart digital card (SD card). The memory card is mainly applied to cooperate with the digital camera or other digital image device. The digital camera is usually equipped with some kind of slot, and the users could store the picture in the memory card therein as soon as they take it. Besides, the users can employ the card reader to interchange the file between the memory card and the hard disc of PC. Comparing to common floppy disc, the memory has much more capacity and faster speed, so the latter became the main stream now. This invention provides one or more slots supporting various types of memory card, displays the digital images in the memory card on the display by using the signal process controller of this invention, and reaches the same effect of printing the digital images out on papers.  
           [0007]    Besides the memory card, the micro drive is one of the popular devices, too. Its I/O means usually adopts the interface of Personal Computer Memory Card International Association. This invention also provides a slot for this interface. The micro drive is a hard disc with the size equal to one coin, but everything needed is there. Hence, besides the interface they use, there is nothing different between the ordinary hard disc and the micro drive. However, the capacity of the micro drive is beyond comparison to the memory card. Ordinary high-capacity memory cards have 128 MB to 256 MB, but the micro drive could equip with several gigabytes. Hence, the micro drive can store high quality multimedia file with huge size. Nevertheless, the micro drive has some defects. It consumes more electricity and its price is higher. Therefore, there are not many supporting device, and the popularity is far away.  
           [0008]    In addition to the storage means above, this invention also provides the interface of USB, RS232, PS/2, IEEE1394, VGA, etc. Consequently, the apparatus of this invention can link to various devices with the ability of operation or storage, such as PC, PDA, digital camera, digital video camera, scanner, VCD player, or DVD player. The images in the storage device of them can be withdrawn and displayed on the display of this invention directly.  
           [0009]    As the data are transferred in various ways mentioned above, they would be handed over to the signal process controller and further disposed, and then deliver to the liquid crystal display of liquid crystal module for displaying. In this way, the effect is the same as that of printing images on papers and the contents displayed can be modified anytime. Besides, the display can be set to change automatically in regular time interval, and the richness of decoration would increase greatly.  
           [0010]    In order to reach foregoing purpose. The present invention disclose a means for displaying having pluralities of memory card slots.  
         SUMMARY  
         [0011]    The main goal of this invention is to display the digital images stored in the memory card on the liquid crystal display (LCD) directly for appreciation without the aid of PC, PDA, or other device capable of operation.  
           [0012]    A means for displaying having pluralities of memory card slots, which supports most types of available memory cards, is disclosed. Users could apply various digital image devices, such as digital camera or digital video camera, to store the images in the memory card therein directly, and use this invention to process them and display them on the LCD.

     DETAILED DESCRIPTION  
       [0017]    This invention discloses a means for displaying with pluralities of memory card slots. In more detail, this invention provides a means for displaying which uses the memory card as the main input device of digital images. The detailed description is presented as follows for illustration instead of limitation.  
         [0018]    As shown in FIG. 1, it is the block diagram of the structure of the means for displaying. The essential components include signal process controller  113 , various memory card slots  101 ˜ 106 , transmission ports of various interfaces  107 ˜ 110 , power source  112 , liquid crystal module (LCM)  114 , and liquid crystal display (LCD)  115 . The signal process controller  113  is the core of this invention, and capable of recognizing whether the input data is the format that can be displayed and processing the data according to their property to let them be displayed on the LCD  115  through LCM  114 . General digital image formats comprise bitmaps (BMP), graphics interchange format (GIF), joint photographic experts group (JPEG), JPG, portable network graphics (PNG), and tag image file format (TIF) The signal process controller  113  employs the software therein to encode the digital image in the format that can be processed by LCM  114 , and displays them on the LCD  115 .  
         [0019]    The main feature of the means disclosed by this invention is that the memory card storing digital images can be inserted into the various slots  101 ˜ 106  of this invention, and the digital images are displayed on the LCD  115  directly. The means of this invention provides various popular memory card slots, which comprise the SD card slot  101  for Smart Digital Card, the PCMCIA slot  102  for devices using PCMCIA interface, CF card slot  103  for Compact Flash card, MS slot  104  for Memory Stick, SM card slot  105  for Smart Media card, and MM card slot  106  for Multi Media card.  
         [0020]    Among them, the PCMCIA slot  102  is mainly provided for Micro Drive, but also for other devices using PCMCIA interface, such as the external CD-ROM drive.  
         [0021]    Through the foregoing interface of memory cards, the various digital images can be transmitted to the signal process controller  113  for further handling and displayed on the LCD  115 . Thus, the purpose of fully utilizing the digital images and the usage of decoration are achieved without printing them on papers or ordinary media. Moreover, since the interfaces provided in this invention embrace almost all those available, this invention is highly compatible.  
         [0022]    Besides, the signal process controller  113  could recognize that the input data is in the formation of either the animation or the video, such as MPEG, AVI, etc. They mainly come from video transmission port  110 , port of IEEE1394 111, or port of USB2.0 109, because these ports have broader bandwidth for huge video file. Similarly, the signal process controller  113  uses the software therein to encode foregoing video file becoming the format that can be processed by the LCM  114  and display it on the LCD  115  immediately.  
         [0023]    The foregoing video transmission port  110  is usually the VGA port of PC and laptop, or the port of audio-visual terminal, and can be applied to connect PC, laptop, VCD player, DVD player, etc. The ports of IEEE1394 111 and of USB2.0 109 are used to link the digital camera, digital video camera, PDA, PC, laptop, external CD-ROM drive, external Hard Discs, etc.  
         [0024]    Moreover, there are ports of RS232 107 and of PS/2 108, and both of them possess narrower bandwidth, hence they are only suitable for general images. The primary linkups include PC, laptop, PDA, etc.  
         [0025]    Therefore, besides the digital images like pictures and photos, this invention can play the digital videos in various formats coming through foregoing transmission ports. Thus, the abundance of the means of this invention further increases.  
         [0026]    Moreover, users can set the display mode through the digital process controller  113 .  
         [0027]    As shown in FIG. 2, it is the flowchart of the setting procedure of the display mode by the digital process controller. First, the input data type is recognized as either digital image or video file  200 . If the recognized type is static digital image  201 , the number of the images therein is recognized  202 . If there exists only one digital image, it would be presented on the LCD  115  directly  207 . Otherwise, if there exist two or more images, it would be determined whether the images are changed dynamically  203 . If it is determined not to change the images dynamically, one digital image would be selected from plural digital images to be displayed  206  and the selected one is presented on the LCD  115  directly  207 . If it is determined to change the images dynamically, two or more digital images have to be selected to be displayed  204 , and the changing time interval is set sequentially  205 . Finally, one of the selected digital images is demonstrated on the LCD  115 ,  207 . For example, if four images are selected and the time interval is set as one hour, the LCM  114  would replace the displaying image by another selected digital image.  
         [0028]    In addition, when the input data are video file  211 , it would be determined whether there exist two or more files or data sources  212 . If there exists only a single file or data source, it would be displayed on the LCD  115  immediately Otherwise, if there exist two or more video files or data sources, it is determined whether they are played in circles  213 . If not, one file or source would be selected  215  and played by the LCD  115  immediately  216 . If so, two or more video files or data sources are selected  214  and played on the LCD  115  in circles immediately  216 . For instance, if there exist three video files in the micro drive in the slot of PCMCIA and one video source of digital video camera connected to the port of USB2.0, and it is decided to play them in circles, some files or sources would be selected to be played. In this situation, we choose two files and the source of digital video camera to play them in circles. They are going to be demonstrated on the LCD  115  one after one, and the diversity is highly increased.  
         [0029]    The display method mentioned-above can make the boring static picture more entertaining, and the setting of playing in circles is able to reach the goal of fully utilizing.  
         [0030]    Hence, because of this invention, the digital images can be easily presented without the aid of papers or traditional media. In addition, the goal of browsing, appreciating, and presenting digital images can be reached without the help of PC or other computing devices. The convenience and practicability is highly provided.  
         [0031]    The preferred example of this invention is illustrated above, and those who are familiar with ordinary skills in this field will appreciate that some modifications can be taken without any divergence from the spirit and scope of this invention. The protection range of this invention should obey the following claims as well as its equal domain.
