Abstract
An image reproduction apparatus which converts a sampling frequency from a first frequency to a second frequency, performs interfield interpolation at a third frequency, and converts the sampling frequency from the third frequency to the first frequency, wherein the interfield-interpolation is performed at the first frequency between signals one field apart from each other. The apparatus also converts a number of vertical scanning lines to convert a high definition TV signal of the MUSE format to a signal of NTSC format, sets a scanning period used in the vertical scanning line conversion, and generates a coefficient used in the vertical scanning line conversion.
