Claim 11:
12. A method for driving a display device, the method comprising:
detecting a logo area including a logo image and a logo background image at a periphery of the logo image, based on input image data;
calculating a binary-coded logo map that distinguishes the logo image and the logo background image;
calculating a preliminary blurring map having blurring candidate values by averaging binary data of pixels included in the logo map, the preliminary blurring map including both binary values and non-binary values;
determining a blurring area of the logo image by comparing each of the blurring candidate values included in the preliminary blurring map and a preset blurring threshold value, wherein the blurring area is smaller than the preliminary blurring map such that the blurring area includes pixels of which the blurring candidate values are larger than the preset blurring threshold value establishing a threshold value for blurring the logo image; and
blurring input image data of pixels included in the blurring area, except input image data of pixels outside the blurring area.
