Abstract
A sketch image is generated based on a brightness of a pixel block that includes a pixel and at least one pixel surrounding the pixel. An output gray scale of the specific pixel is adjusted based on whether an input gray scale of the specific pixel is higher than the representative value. Accordingly, the display apparatus may generate a clear sketch image.
