Abstract
For spatial resolution conversion of an image signal, a magnitude of a motion vector is compared to a threshold value. Single channel interpolation is performed if the magnitude of the motion vector is greater than a threshold value, and multi-channel interpolation is performed otherwise. In addition, single channel interpolation is performed for spatial resolution conversion of any frame that does not refer to another frame.
