Main image processing apparatus, sub image processing apparatus and control method thereof

Abstract

Disclosed are a main image processing apparatus, a sub image processing apparatus and a control method thereof. The control method of the sub image processing apparatus includes receiving a user's touch input through the sub image processing apparatus; determining which contents correspond to a touched area where the touch input occurs; sensing change in location of the touch input; and transmitting a control command for the contents to the main image processing apparatus in response to the sensed change in the location of the touch input. With this, it is more convenient for a user to control the main image processing apparatus through the sub image processing apparatus supporting the touch input.

         8 . The control method of the sub image processing apparatus according to  claim 1 , further comprising:
 receiving information about a power-off state of the main image processing apparatus; and   transmitting a power-on command to the main image processing apparatus.   
     
     
         9 . The control method of the sub image processing apparatus according to  claim 1 , further comprising animating at least one of a menu item selected corresponding to the user touch input and the contents corresponding to the at least one of the menu item. 
     
     
         10 . A control method of a main image processing apparatus connectable with a sub image processing apparatus, the control method comprising:
 receiving a control command for at least one of contents from the sub image processing apparatus; and   displaying the at least one of the contents changed based on the received control command.   
     
     
         11 . The control method of the main image processing apparatus according to  claim 10 , wherein the displaying the at least one of the contents changed based on the control command comprises switching a channel to correspond to the at least one of the contents. 
     
     
         12 . The control method of the main image processing apparatus according to  claim 10 , further comprising turning on the main image processing apparatus if the image processing apparatus is off 
     
     
         13 . The control method of the main image processing apparatus according to  claim 10 , wherein the control command comprises information about rotation at a predetermined angle and in a predetermined direction for the at least one of the contents, and
 the displaying the at least one of the contents changed based on the control command comprises displaying the at least one of the contents rotated at the predetermined angle and in the predetermined direction.   
     
     
         14 . A sub image processing apparatus communicating with a main image processing apparatus, the sub image processing apparatus comprising:
 a communication unit which communicates with the main image processing apparatus;   an image processing unit which processes contents;   a display unit which displays the processed contents;   a user input unit which receives a user touch input; and   a controller which determines which at least one of contents corresponds to a touched area of the user touch input, senses a change in location of the user touch input, and controls the communication unit to transmit a control command for the at least one of the contents to the main image processing apparatus in response to the sensed change in the location of the user touch input.   
     
     
         15 . The sub image processing apparatus according to  claim 14 , wherein the display unit displays the at least one of the contents changed corresponding to the sensed change in the location of the user touch input.
