摘要： A pseudo-contour noise detecting device for detecting pseudo-contour noise is provided. The pseudo-contour noise is embodied as contour lines appearing spuriously in a motion picture displayed such that a gradation display is performed by using a plurality of weighted subfields into which one field of an input image, including a plurality of pixels, is divided. The device includes a pseudo-contour noise calculating unit in which, a logic operation is performed, for each subfield, on each pixel of at least a portion of the input image using a value of the each pixel and values of at least one of the pixels surrounding the each pixel. Further, a value corresponding to an amount of pseudo-contour noise is calculated according to a number of subfields in which a difference is detected between the value of the each pixel and the values of the at least one of the pixels surrounding the each pixel.

摘要： A display apparatus creates, for each image, a number of subfields Z from a first subfield to a Zth subfield in accordance with a Z bit representation of each pixel, a weighing value for each subfield, and a number of gradation display points. The display apparatus detects a peak image brightness level and an average image brightness level. A weighing multiple including a positive integer part and a fractional part is determined based on the peak image brightness level and the average image brightness level. The weighing multiple is multiplied by the weighing value of each subfield to obtain a product capable of having a positive integer part and a fractional part. An integer value near the product is defined as a number of drive pulses for each subfield. The weighing multiple is increased as the average image brightness level decreases and as the peak image brightness level increases.

摘要： A display apparatus has an adjusting device, which acquires image brightness data, and adjusts a weighting multiplier N on the basis of brightness data. The weighting multiplier N takes not only a positive integer, but also a decimal fraction numeral. In accordance with this, even if weighting multiplier N changes, an abrupt change in brightness does not occur, and a person watching the screen is not left with a sense of incongruousness.
