IMAGE-PROCESSING CIRCUIT AND DISPLAY DEVICE HAVING THE SAME

Disclosed are an image-processing circuit capable of improving the ability to express a high-resolution image and a display device having the same and a method of driving a display device. The image-processing circuit determines whether input image data represents one or more of a forward diagonal line edge, a backward diagonal line edge, and a horizontal line edge, and then determines arrangement of a center unit pixel, and thereafter renders data of the center unit pixel into data of a peripheral unit pixel based on edge information and the arrangement of the center unit pixel. 本发明公开了能够提高表示高分辨率图像的能力的图像处理电路以及具有该图像处理电路的显示装置。该图像处理电路判断输入图像数据是否表示正向对角线边缘、反向对角线边缘和水平线边缘中的至少个，并且然后判断中心单元像素的布置，并且此后基于边缘信息和中心单元像素的布置使得中心单元像素的数据渲染为周边单元像素的数据。
