In an error diffusion method and an apparatus thereof for a display system capable of preventing errors of pixels of a certain display region for being affected by pixels of other display regions on a PDP (plasma display panel) device or other display devices, the apparatus includes a boundary region recognition unit for recognizing boundaries of displayed regions by a RGB (red, green, blue) input signal and outputting a boundary recognition signal and an error diffusion processing unit for outputting a RGB output signal by computing an error value between a present pixel and surrounding pixels or outputting a RGB output signal by computing only an error value of the present pixel according to the boundary region recognition signal. |
