Abstract
A line interpolation apparatus, which converts an interlaced scanning image signal into a progressive scanning image signal, wherein the interlaced scanning image signal is obtained by decoding a signal, for which image compression has been performed by using a motion vector that represents the direction and the distance moved in an image; and wherein, as a line interpolation section, a line interpolation method is determined by using both information obtained from the motion vector and information obtained from differences between a pixel to be interpolated and pixels that, in image fields aligned with the time axis of and preceding and succeeding the image field in which the pixel to be interpolated is located, spatially occupy positions corresponding to that of the pixel to be interpolated.
