摘要： A drive pulse controller creates a driving signal for a display device that produces a gradation display. Each field of an input image signal is divided into a plurality of Z weighted subfields. The drive pulse controller determines a number of subfields Z for each field of the input image signal, changes the input image signal into a Z-bit brightness signal, specifies a number of sustain pulses for each subfield within a field, creates a driving signal for each field based on the Z-bit brightness signal and the number of sustain pulses, selects one of light emission time data stored in a time data source based on the determined Z, and calculates a delay time based on the selected light emission time data, such that the most-weighted subfields of consecutive fields having different numbers of subfields Z are positioned substantially at the same time.

摘要： An image display device includes: an interpolation phase generator that generates an interpolation phase on the basis of downsampling frame information representing a downsampling timing at which at least one frame image of the image signal is thinned, and an interpolation frame generator that generates an interpolation frame image corresponding to the interpolation phase. The interpolation phase generator generates the interpolation phase such that a phase distance between a first interpolation frame image from among a plurality of interpolation frame images within one period of downsampling periods, and a second interpolation frame image that follows the first interpolation frame image becomes equal to a phase distance between mutually adjacent interpolation frame images obtained when phase distances between a plurality of interpolation frame images are equalized within one period of the downsampling periods.

摘要： The invention provides an apparatus and a method applied to a plasma display panel or other display panel, achieving a gray scale display by using a plurality of weighted subfields. The apparatus comprises a gray scale limiting/difference diffusion circuit (17) for converting gray scale levels in a supplied image signal to specific gray scale levels that do not easily create pseudo contours in moving picture areas and to intermediate gray scale levels between the specific gray scale levels, and diffusing the difference between the converted gray scale level and the original gray scale level to adjacent pixels, and a dither circuit (19) for generating a video signal to display the converted gray scale level from the circuit (17) alternately in even and odd fields. The dither circuit (19) generates the video signal in which the gray scale levels offset the dither level above and below the dithered gray scale are alternately presented when the converted gray scale level is a dithered gray scale.

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.
