Abstract: The technique of the present invention adjustably sets an image area on a center of an image display area of an image display device for displaying an image expressed by an input image signal and a mask display area surrounding the image area for displaying a black image, based on a user's setting of a parameter representing a projection size. The technique contracts or expands the image expressed by the input image signal to make a size of the image expressed by the input image signal fit a size of the image area in the process of generating a display image signal from the input image signal, while generating the display image signal to make the black image displayed in the mask display area. The projection size is thus adjustable according to the size of the image area and the size of the mask display area, which are set based on the parameter representing the projection size. This arrangement ensures simple adjustment of the projection size of the image by the projector.

Abstract: A 525i (interlace) signal can be converted into a 1050i signal or a 525p (progressive) signal. A calculating circuit generates pixels of an output picture signal with a linear estimation expression of predictive taps received from a tap selecting circuit and a coefficient received from a coefficient memory. The coefficient memory stores coefficients pre-obtained for individual classes. A class is determined by combining a spatial class corresponding to spatial class taps received from a tap selecting circuit and motion class taps received from a tap selecting circuit. A line sequential converting circuit converts a scanning line structure of an output signal of the calculating circuit 34 and obtains an output picture signal. The output picture signal is designated with a conversion method selection signal. Information corresponding to the selection signal is loaded from an information memory bank to the coefficient memory and registers.

Abstract: A first motion vector is estimated by using a first frame and a second frame that follows the first frame. A support frame is generated from at least either the first or the second frame by using the first motion vector. The support frame is divided into a plurality of small blocks. Motion vector candidates are estimated by using the first and second frames, in relation to each of the small blocks. A small block on the first frame, a small block on the second frame and the small blocks on the support frame are examined. The small block on the first frame and the small block on the second frame correspond to each of the motion vector candidates. A second motion vector is selected from the motion vector candidates, and points the small block on the first frame and the small block on the second frame which have the highest correlation with each of the small blocks on the support frame. An interpolated frame is generated from at least either the first or the second frame by using the second motion vector.

Abstract: The present invention is related to a video signal processing apparatus and method, a recording medium, and a program which are suitably for use in determining whether an input video signal is standard or nonstandard. In synchronization with the edge of an advance vertical sync signal xAVD, a free-running vertical sync edge counter 31 increments by 1 the count value which cycles between 0 through 7 and outputs the count value to a free-running field ID edge counter 32 and a comparator 33. In synchronization with the rising and falling edges of a field ID signal AFD, the free-running field ID edge counter 32 increments the count value by 1. The comparator 33 generates a nonstandard signal detection signal in correspondence with the FD edge count value with the V count value being 7 and a vertical sync signal xVD being at L level. The present invention is applicable to TV receivers for example.

Abstract: The present invention provides an adaptive Y/C separation circuit for video signal processing that is capable of correcting previous color discrepancy in separating the luminance (Y) and chrominance (C) signals from the color video signals. In the process, the correlation of video signals on referencing scanning lines is analyzed by transposing the chrominance signals onto a two-dimensional UV plane. A correlation coefficient is obtained through the analysis for adjusting the video signals in the direction of the actual chrominance level, thus separating the luminance and chrominance signals with relatively low cost circuit implementation.
