The present invention relates to a plasma display apparatus and an image processing method thereof, and more particularly, the present invention relates to an improved plasma display apparatus and an image processing method thereof which can enhance a gray level representation capability. The plasma display apparatus according to one embodiment of the present invention comprises a plasma display panel including a plurality of address electrodes; an inverse gamma correction section for inverse gamma-correcting an image signal inputted from an exterior; a halftone section in which a subordinate bit of a fraction bit of the image signal which is inverse gamma-corrected divides a plurality of pixels adjacent to each other into at least two or more types, an error diffusion is performed among the pixels corresponding to any one type, and a superior bit of the fraction bit performs a dithering using at least two or more dither mask patterns; and a subfield mapping section for mapping the image signal which is halftone processed on the corresponding subfield. The present invention is advantageous in that the flicker phenomenon is suppressed when the plasma display apparatus is operated and a distortion of the embodied image can be prevented.
