摘要： 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.

摘要： 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 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.
