Abstract:
A line interpolation apparatus, which converts an interlaced scanning image signal into a progressive scanning image signal, comprising:a signal obtaining section adapted to obtain the interlaced scanning image signal by decoding a signal, for which image compression has been performed, using a motion vector that represents the direction and distance moved in an image; and a process determining section adapted to determine a line interpolation process by using both information obtained using the motion vector and information obtained by calculating 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; and a line interpolation section adapted to apply the line interpolation process determined by the process determining section to the interlaced scanning image signal obtained by the signal obtaining section.
