  • Patent number: 7586540
    Abstract: 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.

  • Publication number: 20090059067
    Abstract: A motion vector detection apparatus is disclosed capable of detecting accurate motion vectors from between a previous frame of image and the presently displayed frame of image even in edge regions of the frames where inaccurate motion vectors would normally tend to be detected. A motion vector-detecting portion reads in an image signal from the signal input portion as well as image signals entered through first through third frame memories. Processing for detecting motion vectors is performed, based on four frames entered in synchronism to the motion vector-detecting portion out of the frames forming the image signals. Vectors produced between the image signal from the first frame memory delayed by one frame relative to the image signal from the signal input portion and the image signal from the second frame memory delayed by two frames relative to the image signal from the signal input portion are detected as motion vectors.

  • Publication number: 20080240562
    Abstract: 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.

  • Publication number: 20080180455
    Abstract: 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 ±1/3 pixel from the input R and B sub-pixels and the pixel gravitys of which are displaced by ±1/3 or ±1/8 pixel in accordance with the kind of the edge are generated.

  • Publication number: 20080170161
    Abstract: A picture signal processing apparatus is provided with: a motion vector detecting unit for detecting information as to a motion vector of a picture from a plurality of 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 a plurality of interpolation frames are continued between two frames of the input picture signal, at least one interpolation frame among the plurality of interpolation frames is formed as such an interpolation frame formed without employing the motion vector (namely, not depending upon motion of picture).

    Abstract: 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.
