<p>A plasma display apparatus includes an object division unit for detecting an edge from a received m-bit image signal and dividing an object surrounded by the edge, and an image signal conversion unit for dividing between-gray levels of pixels constituting the divided object and converting the m-bit image signal into a n-bit image signal (where n is a natural number greater than m). By finely dividing between-gray levels allocated to pixels corresponding to a divided object, the gray linearity can be improved.</p> |
