摘要： 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.

摘要： 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).
