摘要： In an image signal processing unit in a PDP device, a noise reducer unit is provided at a former stage of an error diffusion processing unit. The noise reducer unit has an LPF to input display data and an edge determining unit and a level determining unit to the LPF. Switching between an output which has passed through the LPF and an output which has not passed through the LPF is performed in a data selecting unit according to a pixel region in display data based upon respective determination results, and the selected signal is outputted as output display data. Noise contained in the input display data is reduced by the noise reducer unit while maintaining the fineness of an image. Accordingly, a technology capable of eliminating or reducing noise in display data while maintaining fineness of a display image is provided for digital display.

摘要： In a plasma display apparatus with power consumption control, a control method is provided that eliminates unnaturalness of images during power control and that holds power consumption to within a target value regardless of the type of image pattern displayed. Differences between power consumption PSA and target value PSET are summed to calculate power consumption sum value PSUM, and if PSUM is negative, brightness set value MCBC is set to its maximum value MCBCMAX. If PSUM is positive, the value calculated by the equation “MCBCMAX−PSUM×MCBCMAX/PSUM,MAX” is set as the MCBC.

摘要： The plasma display device has a plasma display panel and a driving part for driving the plasma display panel in a subframe mode. The driving part has a circuit for calculating the length of one frame based on one period of a vertical synchronizing signal introduced along with an image signal from an external device, a circuit for calculating the total number of sustaining pulses contained in one frame based on a brightness information contained in the image signal, and a circuit for calculating the length of one driving period required for displaying one frame. The length of one frame and the length of one driving period thus obtained are then compared in a comparing circuit. If the one frame length is found to be shorter than the one driving length, the total number of sustaining pulses or the number of scan lines will be reduced so that the one frame length becomes shorter than the length of one driving period, thus avoiding an extraordinary display.

摘要： According to the present invention, a plasma display apparatus, which represents the luminance of one frame in accordance with a combination of plural sub-frames having luminance levels corresponding to a plurality of weighted values, additionally includes a sub-frame having a luminance level lower than the minimum gray scale level of luminance which can be represented by the number of bits in the input video data. Such plasma display apparatus turns on a desired combination of the sub-frames so as to increase the resolution of the luminance without increasing the conventional number of gray scale levels included in the input video data. In a preferred embodiment, especially when the added smaller luminance sub-frame is included in a combination of sub-frames for a low luminance area, the resolution of the gray scale of the low luminance area can be increased, and the representation of gray scale can be enhanced in a low luminance area to which the sight of a person is more sensitive.
