 based on the distance being identified to be greater than a predetermined threshold value, perform at least one first function of the user touches on each of the plurality of regions, and 
 based on the distance being identified to be less than the predetermined threshold value, perform a second function of the user touches on a single region including the plurality of regions. 
   
     
     
         2 . The electronic apparatus according to  claim 1 , wherein the at least one first function is at least one of a drawing function or a dragging function along a moving path of the user touches on each of the plurality of regions. 
     
     
         3 . The electronic apparatus according to  claim 1 , wherein the at least one first function comprises a plurality of functions which are different from one another, and
 the processor is configured to perform the plurality of functions on the plurality of regions, respectively.   
     
     
         4 . The electronic apparatus according to  claim 1 , wherein the second function is an erasing function along a moving path of the user touches on the single region. 
     
     
         5 . The electronic apparatus according to  claim 1 , wherein the controller is further configured to perform either the first function or the second function of the user touches based on a moving speed of the user touches. 
     
     
         6 . The electronic apparatus according to  claim 1 , wherein the controller is further configured to change the predetermined threshold value based on a user input. 
     
     
         7 . The electronic apparatus according to  claim 6 , wherein the controller is further configured to provide guide information for receiving the user input to change the predetermined threshold value. 
     
     
         8 . The electronic apparatus according to  claim 7 , wherein the controller is further configured to identify whether a plurality of test user touches is multiple touches or a single touch based on confirmation of the user input. 
     
     
         9 . The electronic apparatus according to  claim 8 , wherein the controller is further configured, based on the plurality of test user touches being identified to be the multiple touches or the single touch, to provide the guide information which comprises information recommending a distance between the plurality of test user touches to be adjusted. 
     
     
         10 . The electronic apparatus according to  claim 7 , wherein the controller is further configured to change the predetermined threshold value based on a direction of the plurality of test user touches. 
     
     
         11 . A method of controlling an electronic apparatus, the method comprising:
 displaying an image on a screen;   identifying a distance between a plurality of regions of the screen on which user touches are respectively sensed;   based on the distance being identified to be greater than a predetermined threshold value, performing at least one first function of the user touches on each of the plurality of regions, and   based on the distance being identified to be less than the predetermined threshold value, performing a second function of the user touches on a single region including the plurality of regions.   
     
     
         12 . The method according to  claim 11 , wherein the at least one first function is at least one of a drawing function or a dragging function along a moving path of the user touches on each of the plurality of regions. 
     
     
         13 . The method according to  claim 11 , wherein the at least one first function comprises a plurality of functions which are different from one another, and
 the performing the at least one first function comprises performing the plurality of functions on the plurality of regions, respectively.   
     
     
         14 . The method according to  claim 11 , wherein the second function is an erasing function along a moving path of the user touches on the single region. 
     
     
         15 . The method according to  claim 11 , wherein the performing comprises performing either the first function or the second function of the user touches based on a moving speed of the user touches. 
     
     
         16 . The method according to  claim 11 , further comprising changing the predetermined threshold value based on a user input. 
     
     
         17 . The method according to  claim 16 , wherein the changing comprises providing guide information for receiving the user input to change the predetermined threshold value. 
     
     
         18 . The method according to  claim 17 , wherein the changing comprises identifying whether a plurality of test user touches is multiple touches or a single touch based on confirmation of the user input. 
     
     
         19 . The method according to  claim 18 , wherein the providing comprises, based on the plurality of test user touches being identified to be the multiple touches or the single touch, providing the guide information which comprises information recommending a distance between the plurality of test user touches to be adjusted.
