ABSTRACT:
A method of converting and displaying scan lines for displaying interlace video signals permitting television or the like, represented by the NTSC standard, on a non-interlace display apparatus, including a reduction of images. Scan lines of a video signal are converted by a horizontal coordinate conversion circuit, a horizontal filtering circuit, a vertical coordinate conversion circuit, a vertical filtering circuit, and a one-scan line portion of line memory. The coordinates are converted on the basis of the coordinate system of the frame of the interlace video signal; and filtering in the vertical direction is performed in field units based on the coordinate conversion.
