An image displaying apparatus, for improving motion blur, in particular, on an image displaying apparatus of hold-type, such as, a liquid crystal display element, etc., comprising: sub-frame producing portions (5, 6) for producing a first sub-frame, a second sub-frame being lower in the gradation than the first sub-frame, from an image of one (1) frame of an image signal inputted; a histogram detection portion (2) for detecting brightness histogram of the image signal; an image determination portion (3) for determining on whether the image signal inputted is a high-gradation image or not, from that brightness histogram; and a level compensation portion (4) for lowering a gradation level of that image signal inputted. And, according to the present invention, lowering the gradation of the high-gradation image keeps the difference in brightness between the first and the second sub-frames, and thereby increasing an effect of improving the motion blur.

When a reproduction device and a display device are separated, there is the risk that it will not be possible to appropriately overly menu images or the like on a 3D video signal in the reproduction device. This reproduction method, which outputs a video signal generated in a reproduction device to a display device, has: a step for reproducing a video signal; a step for generating image information to be superimposed on the reproduced video signal; a step for superimposing the generated image information on the reproduced video signal; a step for outputting the video signal to which the image information has been superimposed; a step for reading information relating to the display device from the display device; and a step for acquiring information relating to the state of the display device from the display device. The configuration is such that the method of superimposing the image information on the video signal is altered on the basis of the acquired information relating to the state of the display device and the read information relating to the display device.

Image processing apparatus and image processing method including an image separation processing section for separating an inputted image signal into a transparent image portion having transparency and a background image by detecting a pixel data common among a plurality of frames within the inputted image signal; a frame interpolator that performs frame interpolation using the separated background image; and a composition processing section for combining the frame-interpolated background image with the separated transparent image portion, wherein the frame interpolation is performed only to the background image so that the influence on the frame interpolation of the transparent image portion is reduced.

An RGB signal from an input terminal is supplied to a triple over-sampling/sub-pixel control processing unit and a brightness signal generating circuit in which a brightness signal is generated. A brightness edge detection/judgment unit detects an edge from this brightness signal, judges the kind of the edge, fetches a coefficient select signal corresponding to the judgment result from a memory and supplies the signal to the control processing unit. A tap coefficient corresponding to this coefficient select signal is set in the control processing unit and a triple over-sampling processing is executed for each of RGB. For edge parts, R and B sub-pixels the timings of which are displaced by ±⅓ pixel from the input R and B sub-pixels and the pixel gravitys of which are displaced by ±⅓ or ±⅛ pixel in accordance with the kind of the edge are generated.

A picture signal processing apparatus includes a motion vector detecting unit for detecting information as to a motion vector of a picture from frames contained in an input picture signal; an interpolation frame producing unit for producing an interpolation frame by employing the motion vector; and a frame stream producing unit for producing a picture signal of a new frame stream by combining the interpolation frame produced with the frames of the input picture signal so as to output the produced picture signal of the new frame stream. When the picture signal processing apparatus performs a converting operation in such a manner that interpolation frames are continued between two frames of the input picture signal, at least one interpolation frame among the interpolation frames is formed as such an interpolation frame formed without employing the motion vector (namely, not depending upon motion of picture).

More accurate frame-rate conversion is carried out in a simpler circuit configuration. Search areas SA+1 and SA−1 in each of which the pixel facing the interpolation position P0 of a pixel in an interpolation frame is taken as a central pixel are set in the current frame and immediately previous frame of an image signal, a set of pixels point-symmetrical to the interpolation position P0 in each of the search areas SA+1 and SA−1 are defined as pixel pairs, and differential luminance values between the individual pixels in the pixel pairs are calculated for each pixel pair. Of all these pixel pairs, only that having the minimum absolute differential value is selected as interpolation pixel pair, an interpolation frame is generated from the current frame and the immediately previous frame on the basis of the interpolation pixel vector of that interpolation pixel pair.
摘要:
An MIS transistor fabricated in a manner that minimizes the occurrence of leak currents and that improves overall transistor performance by minimizing variation in location of the transistor source and drain during fabrication thereof. A gate electrode is first fabricated on a substrate. Next, a thermal oxide layer is formed on a side of the gate electrode. A masking process is then performed with the thermal oxide layer to form a source and a drain. A silicon oxide layer is then deposited over the gate electrode, the source and the drain. An etching process is performed on the silicon oxide to form a side wall oxide film over the thermal oxide layer on the side of the gate electrode and to expose surfaces of the gate electrode, the source and the drain. A metal film is then deposited over the gate electrode, the source and the drain and is heat treated to form a metal silicide film on the exposed surfaces of the gate electrode, the source and the drain. The side wall oxide film functions to disperse the metal silicide film as it is deposited to electrically separate the gate electrode, the source and the drain, thereby preventing a leakage current from occurring.
