An image processing method, an image processing circuit, and a display apparatus using the same are discussed. The image processing method can include sensing a viewing distance of a user and determining a predetermined viewing distance mode, upon determining that the viewing distance corresponds to a short distance mode, performing blurring processing on four-color data of each pixel of an input image for each color channel by applying a predetermined blurring mask to reduce data of an edge portion of the input image and to output the image, and upon determining that the viewing distance corresponds to a long distance mode, performing sharpening processing on white data of four-color data of each pixel of the input image by applying a predetermined sharpness mask to increase the white data of the edge portion of the input image and to output the image.
