An apparatus and method for attenuating luminance of a plasma display panel (PDP) to prevent degradation of picture quality on a local area and an increase in power consumption are provided. The apparatus includes a motion detection unit for detecting whether input data has motion, a duration check unit for checking a duration time for which the input data has no motion when the input data is detected as having no motion in the motion detection unit, an attenuation constant generator for generating an attenuation constant corresponding to a luminance level of the input data when the input data continuously has no motion for at least a predetermined period of time, and a level attenuation unit for attenuating the luminance level of the input data using the attenuation constant generated from the attenuation constant generator. Accordingly, degradation of picture quality on a local area, which does not influence an average luminance level for a frame, and an increase in power consumption due to the degradation can be prevented. |
