摘要： A first video signal generation circuit newly generates pixels between pixels in a first progressive video field signal outputted by a first progressive video generation circuit, and outputs a third progressive video field signal. A second video signal generation circuit newly generates pixels between pixels in a second progressive video field signal outputted by a second progressive video generation circuit, and outputs a fourth progressive video field signal. A comparison circuit compares the third progressive video field signal and the fourth progressive video field signal, and outputs the result of the comparison as motion amount information. An output circuit synthesizes an intra-field interpolation signal and a frame interfiled interpolation signal on the basis of the motion amount information, and outputs a composite signal as a progressive video signal.

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： 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.
