    • Image display quality of a plasma display apparatus is enhanced. For this purpose, the plasma display apparatus includes a number-of-sustain-pulses corrector for controlling the number of sustain pulses to be generated. The number-of-sustain-pulses corrector includes an all-cell light-emitting rate detection circuit (46), a partial light-emitting rate detection circuit (47), and a lookup table. The number-of-sustain-pulses corrector sets a correction coefficient that is read out from the lookup table in response to an all-cell light-emitting rate and a partial light-emitting rate as a first correction coefficient, and a recorrection coefficient that is based on the first correction coefficient. The number-of-sustain-pulses corrector adjusts the first correction coefficient and the recorrection coefficient, using an adjustment gain preset for each subfield in response to the magnitude of the luminance weight. The number-of-sustain-pulses corrector corrects the number of sustain pulses, using the first correction coefficient and the recorrection coefficient adjusted with the adjustment gain.

    • The image display quality of the plasma display apparatus is improved. For this purpose, the plasma display apparatus corrects the number of generated sustain pulses in each subfield using a first correction coefficient that is read from look-up table (62) in response to the all-cell light-emitting rate and the partial light-emitting rates and a common correction coefficient. The apparatus adds preset offset value OFST to the all-cell light-emitting rate, multiplies the addition result by the number of sustain pulses in each subfield, and calculates the sum total of the multiplication results in one field period to calculate an estimated value of the power consumption in one field period. The apparatus sets the common correction coefficient so that the estimated value of the power consumption in one field period before the correction using the first correction coefficient and the common correction coefficient is equivalent to that after the correction.
