<p>The present invention relates to a plasma display apparatus, and more particularly, to a plasma display apparatus for expressing images by processing input image signals and an image processing method thereof. The plasma display apparatus for expressing images by processing image signals comprises: an inverse gamma correction unit linearly transforming a luminance value depending on the gray scale of an image signal by inverse gamma correction of input image signal data; and a halftoning unit masking at least two dither mask patterns in random order with respect to the inverse gamma corrected image signal data.
