Abstract
A method and an apparatus for interpolating a scanning line of a TV signal in a TV, wherein a diagonal component of a video signal of the TV signal is considered and there can be prevented a line structure, a line flicker and a vertical resolution insufficiency due to shortage in the number of the scanning lines. The apparatus of the invention comprises a scanning line interpolator for obtaining vertical, horizontal and diagonal variations of a received video signal of the TV signal and considering a weight with respect to a signal of the smallest variation, so as to obtain an interpolation signal, a first time compressor for compressing the time of an output signal from the scanning line interpolator by 2 to 1, a second time compressor for compressing the time of the received video signal by 2 to 1, and a switch for selecting an output signal from the second time compressor with respect to a position of the original signal and selecting an output signal from the first time compressor with respect to a position to be interpolated.
