Image processing device and display device including the same

Abstract

An image processing device includes an image determiner which determines whether an image data is a still image or a motion picture image, a first compensator which gradually changes a scaling ratio of the image data of which a center part is fixed and a second compensator which divides the image data into a plurality of sub-image data and change a scaling ratio of the sub-image data.

         3 . The image processing device of  claim 2 , wherein the first compensator gradually expands or reduces the image data of which the center part is fixed in response to the first compensating signal. 
     
     
         4 . The image processing device of  claim 2 , wherein the first compensator expands or reduces the image data based on the scaling ratio. 
     
     
         5 . The image processing device of  claim 2 , wherein the first compensator restores the image data by gradually expanding the image data of which the center part is fixed in response to the second compensating signal. 
     
     
         6 . The image processing device of  claim 2 , wherein the second compensator reduces one of the plurality of sub-image data in response to the first compensating signal. 
     
     
         7 . The image processing device of  claim 6 , wherein the second compensator controls the scaling ratio of the plurality of sub-image data which is not reduced. 
     
     
         8 . The image processing device of  claim 2 , wherein the second compensator restores the plurality of sub-image data of which the scaling ratio is changed in response to the second compensating signal. 
     
     
         9 . The image processing device of  claim 1 , the image determiner alternately provides a first compensating signal to the first compensator and a second compensator when the image data is the still image. 
     
     
         10 . A display device comprising:
 a display panel including a plurality of pixels;   an image processor which gradually changes a scaling ratio of an image data of which a center part is fixed or change the scaling ratio of sub-image data into which the image data is divided based on whether the image data is a still image or a motion picture image;   a scan driver which provides a scan signal to the plurality of pixels;   a data driver which provides a data signal to the plurality of pixels; and   a timing controller which generates a control signal which controls the scan driver and the data driver.   
     
     
         11 . The display device of  claim 10 , wherein the image processor includes:
 an image determiner which determines whether the image data is the still image or the motion picture image;   a first compensator which gradually changes the scaling ratio of the image data of which the center part is fixed; and   a second compensator which divides the imaged data into the sub-image data and change the scaling ratio of the sub-image data different from each other.   
     
     
         12 . The display device of  claim 11 , wherein the image determiner provides a first compensating signal to the first compensator or the second compensator when the image data is the still image, and
 wherein the image determiner provides a second compensating signal to the first compensator or the second compensator when the image data is the motion picture image.   
     
     
         13 . The display device of  claim 12 , wherein the first compensator gradually expands or reduces the image data of which the center part is fixed in response to the first compensating signal. 
     
     
         14 . The display device of  claim 12 , wherein the first compensator expands or reduces the image data based on the scaling ratio. 
     
     
         15 . The display device of  claim 12 , wherein the first compensator restores the image data by gradually expanding the image data of which the center part is fixed in response to the second compensating signal. 
     
     
         16 . The display device of  claim 12 , wherein the second compensator reduces one of the sub-image data in response to the first compensating signal. 
     
     
         17 . The display device of  claim 16 , wherein the second compensator controls the scaling ratio of the sub-image data which is not reduced. 
     
     
         18 . The display device of  claim 12 , wherein the second compensator restores the sub-image data of which the scaling ratio is changed in response to the second compensating signal. 
     
     
         19 . The display device of  claim 11 , wherein the image determiner alternately provides a first compensating signal to the first compensator and the second compensator in a predetermined cycle when the image data is the still image.
