         2 . The digital image processing apparatus of  claim 1 , wherein the digital signal processor comprises:
 a connection detector which detects whether the digital image processing apparatus and the external display apparatus are connected to each other;   a display selector which selects one of the digital image processing apparatus and the external display apparatus to display the screens obtained by performing the first and second display commands; and   a controller which performs the first and second display commands.   
     
     
         3 . The digital image processing apparatus of  claim 1 , wherein the first display command displays an image selected from among images stored in the digital image processing apparatus in a full screen, and the second display command displays an enlarged or reduced image of a partial area selected from the full screen on the external display apparatus. 
     
     
         4 . The digital image processing apparatus of  claim 3 , wherein an on-screen display (OSD) image, which displays a window on the selected partial area on the full screen, is further displayed. 
     
     
         5 . The digital image processing apparatus of  claim 1 , wherein the first display command displays an image selected from among images stored in the digital image processing apparatus on the digital image processing apparatus in a full screen, and the second display command displays an image, on which a special effect is performed on the selected image, on the external display apparatus. 
     
     
         6 . The digital image processing apparatus of  claim 5 , wherein options of the special effect are displayed on the digital image processing apparatus in an on screen display (OSD) image. 
     
     
         7 . The digital image processing apparatus of  claim 5 , wherein the second display command displays the selected image and the image, on which the special effect is performed, on the external display apparatus by dividing a screen of the external display apparatus. 
     
     
         8 . The digital image processing apparatus of  claim 1 , wherein the first display command displays images stored in the digital image processing apparatus in a continuous reproduction mode at a predetermined speed on the digital image processing apparatus, and the second display command displays the images on the external display apparatus at a speed different from the predetermined speed of the continuous reproduction mode. 
     
     
         9 . A method of operating a digital image processing apparatus that supports multi-display to reproduce images on an external display apparatus connectable to the digital image processing, the method comprising:
 inputting a signal of a first display command to the digital image processing apparatus;   inputting a signal of a second display command to the digital image processing apparatus;   selecting any one of the digital image processing apparatus and the external display apparatus to display screens obtained by performing the first and second display commands; and   displaying the screens obtained by performing the first and second display commands.   
     
     
         10 . The method of  claim 9 , wherein the selecting comprises detecting whether the digital image processing apparatus and the external display apparatus are connected to each other. 
     
     
         11 . The method of  claim 9 , further comprising:
 displaying, by the first display command, an image selected from among images stored in the digital image processing apparatus in a full screen; and   displaying, by the second display command, an enlarged or reduced image of a partial area selected from the full screen on the external display apparatus.   
     
     
         12 . The method of  claim 11 , wherein the first display command further displays an on-screen display (OSD) image, which displays a window around the selected partial area on the full screen. 
     
     
         13 . The method of  claim 9 , further comprising:
 displaying, by the first display command, an image selected from among images stored in the digital image processing apparatus on the digital image processing apparatus in a full screen; and   displaying, by the second display command, an image on which a special effect is performed on the selected image on the external display apparatus.   
     
     
         14 . The method of  claim 13 , wherein the first display command further displays options of the special effect on the digital image processing apparatus in an on screen display (OSD) image. 
     
     
         15 . The method of  claim 13 , wherein the second display command displays the selected image and the image, on which the special effect is performed, on the external display apparatus by dividing a screen of the external display apparatus. 
     
     
         16 . The method of  claim 9 , further comprising:
 displaying, by the first display command, images stored in the digital image processing apparatus in a continuous reproduction mode at a predetermined speed on the digital image processing apparatus; and   displaying, by the second display command, images on the external display apparatus at a speed different from the predetermined speed of the continuous reproduction mode.   
     
     
         17 . A computer program product, comprising a computer usable medium having a computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a method for operating a digital image processing apparatus that supports multi-display to reproduce images on an external display apparatus connectable to the digital image processing, the method comprising:
 inputting a signal of a first display command to the digital image processing apparatus;   inputting a signal of a second display command to the digital image processing apparatus;   selecting any one of the digital image processing apparatus and the external display apparatus to display screens obtained by performing the first and second display commands; and   displaying the screens obtained by performing the first and second display commands.
