Claim Text:
1. A display apparatus comprising: an image processor which processes a non-photorealistic rendering (NPR) with respect to an image; and a display unit which displays the NPR-processed image, wherein pixels of the image have respective brightness values, and wherein the image processor processes the NPR by reducing a brightness value of each pixel, among pixels of the image, having a brightness value less than a predetermined brightness value and increasing a brightness value of each pixel, among the pixels of the image, having a brightness value greater than the predetermined brightness value, wherein the image processor performs quantization so that the image is made up of a plurality of brightness levels for generating the NPR-processed image, and wherein the quantization comprises quantizing the image by using a first gamma curve corresponding to a first level section of the plurality of brightness levels and a second gamma curve corresponding to a second level section of the plurality of brightness levels.
