摘要: Image quality deterioration resulting from a dither process is controlled by using a matrix like random pattern as a dither toggle pattern in signal processing for display such as a plasma display. A matrix like random pattern is generated for each frame in a pseudorandom code generator as a dither toggle pattern, or is reused after reversing bits.

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.
