摘要： According to the invention, by forming at least every two frames having video contents corresponding to each frame of a video signal, for example, a frame rate of movie contents whose frame rate is equal to 24 Hz is converted into 48 Hz. A plurality of subfields (SFs) corresponding to each frame of the conversion signal are divided into first and second division SF groups. Each division SF group is further classified into an upper SF group on the large weight side and a lower SF group on the small weight side. The weights of the upper SF groups are made symmetrical between the first and second division SF groups. The weight of each SF belonging to the lower SF group in the first division SF is set to be larger than that in the second division SF.

摘要： A display method of a plasma display apparatus to which primary color video signals are inputted and which carries out color display by letting phosphors for primary colors emit light is provided. The display method displays the primary color video signals by changing a gray level of an output primary color video signal in accordance with a gray level of an input primary color video signal. When each gray level of the inputted primary color video signals changes from a first value to a second value which is larger than the first value, a gray level of a primary color video signal for a phosphor having the largest influence of luminance saturation properties among the phosphors is increased relative to a gray level of the other primary color video signal.

摘要： A display apparatus, which displays a color image by controlling the number of emissions or the intensity thereof in accordance with primary color video signals input thereto, has a detection portion and a white balance correction portion. The detection portion is used to detect the number of emissions or the intensity, and the white balance correction portion is used to correct white balance by adjusting the amplitudes of the primary color video signals in accordance with the detected number of emissions or the detected intensity. Therefore, correct white balance can be maintained regardless of the number of emissions or the intensity of emission.
