Provided are a plasma display apparatus which performs error diffusion and an image processing method of a plasma display apparatus. The plasma display apparatus comprises an APL calculation block for calculating an APL upon receipt of an image signal, a displacement noise calculation block for calculating the intensity of overall displacement noise corresponding to the amount of displacement of an image of the image signal according to a displacement noise calculation value including the APL, a displacement noise supply block for supplying a displacement noise signal to the image signal according to the intensity of the overall displacement noise, a halftone block for performing halftoning for the image signal to which the displacement noise signal is applied and a plasma display panel for displaying an image corresponding to the signal output from the halftone block. Picture quality can be improved because noise caused by error diffusion can be reduced.
