ABSTRACT:
This document relates to a display apparatus, and more particularly, to an image processing apparatus and method of a plasma display panel. An image processing apparatus of a plasma display panel according to an embodiment of the present invention comprises an inverse gamma correction unit that gamma-corrects an image signal through previous stored gamma data, a half-toning unit that adds an error diffusion error value (Ei) of neighboring pixels to a noise value (n(i, j)) of a predetermined pattern and diffuses the added result into the inverse gamma corrected image signal, and a sub-field mapping unit that maps the half-toned image signal to a sub-field mapping table.
