CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims the benefit under 35 U.S.C. §119 of Korean Patent Application No. 10-2009-0094755, filed Oct. 6, 2009, which is hereby incorporated by reference in its entirety. 
       BACKGROUND OF THE DISCLOSURE 
       [0002]    1. Field of the Invention 
         [0003]    The present disclosure relates to a microscope camera and a mobile terminal having the same. 
         [0004]    2. Description of Related Art 
         [0005]    Generally, a microscope is a kind of a magnifying glass capable of seeing a small object by enlarging the same. The microscope is generally equipped with a reflective minor configured to reflect light incident on an object from outside to a light collecting lens. The microscope is utilized for observing a microorganism that requires fine observation and a fine structure of a semiconductor integrated circuit that cannot be discerned with the naked eye. The microscope is also used for various other fields such as material engineering and medical fields. 
         [0006]    Recently, a microscope camera is provided to check an object (test object) with the naked eye and to check the object by connecting a display device such as, but not limited thereto, a computer monitor, a TV or a printer. 
         [0007]    The microscope camera can capture a still object or a living microorganism, observe a continuous operation change through a display device, and store/manage the captured object or microorganism in a data. 
         [0008]    However, the microscope camera is disadvantageous in that it is difficult to install a computer monitor or a TV set on which an image captured through the microscope camera is to be checked due to restraint on installation and bulkiness, and it is uncomfortable to carry the computer monitor or the TV set, leading to decreased mobility.

         [0057]    The synchronized signal generator  534  may generate a reference generating V-sync and H-sync of the image sensor  532 , and a synchronization signal for a serial communication of the slave controller  535 , and supply a reference clock during a serial storage in the memory  537 . 
         [0058]    The slave controller  535  is a controller configured to transmit a serial data which is an image data of the camera module  530 , from the camera module  530  to the mobile terminal  600 . The slave controller  535  may output a USB slave mode signal in a case the connection cable  700  is inserted into the mobile terminal  600 , and it is preferable that a USB slave controller configured to convert a parallel data to a serial data be used. 
         [0059]    The connector  536  may connect a signal line between the camera module  530  and the mobile terminal  600 . The memory  537  may store an image data digitalized by the image sensor  532 , or store a parallel data converted from the slave controller  535 .

Furthermore, the user may transmit the photo captured by the mobile terminal  600  to other mobile terminals. 
         [0061]      FIG. 3  is a flowchart illustrating an operation of a camera module connected to a mobile terminal according to an exemplary embodiment of the present invention. 
         [0062]    Referring to  FIG. 3 , the connection cable  700  is inserted into the mobile terminal  600  (S 110 ). The image sensor  532  is initialized by the slave controller  535  (S 120 ). At this time, the camera module  530  may transmit the USB slave mode signal to the mobile terminal  600 . 
         [0063]    The image signal from the image sensor  532  is converted to YUV data format to cater to USB protocol (S 130 ). The converted data is transmitted to the mobile terminal  600  connected via the USB cable  700  (S 140 ). 
         [0064]      FIG. 4  is a flowchart illustrating an operation of a mobile terminal connected to a camera module according to an exemplary embodiment of the present invention. 
         [0065]    Referring to  FIG. 4 , in a case the USB slave mode signal is received from the camera module  530 , the USB slave mode signal is converted to USB host mode (S 210 ). The USB host mode is a mode outputted by storing, manipulating the data received from the camera module  530  via the connection cable  700 , or outputting the data via the display unit  610 . The data received via the connection cable  700  is stored in the display memory (S 220 ). 
         [0066]    The data of the display memory is outputted to the display unit  610  using a JAVA application program (S 230 ). The user may capture a desired image using the JAVA application program for storage in the memory. Thereafter, the user may transmit the captured image to other mobile terminals or a computer. 
         [0067]    Although the present disclosure has used the JAVA application program for outputting an image data onto a display unit or capturing the image, the present exemplary embodiment is illustrative only, and it should be apparent to those in the skilled in the art that various programs other than the JAVA application program may be used. 
         [0068]    The above-mentioned microscope camera and mobile terminal using the same according to the present disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Thus, it is intended that embodiments of the present disclosure may cover the modifications and variations of this disclosure provided they come within the scope of the appended claims and their equivalents. 
         [0069]    While particular features or aspects may have been disclosed with respect to several embodiments, such features or aspects may be selectively combined with one or more other features and/or aspects of other embodiments as may be desired.
