Abstract
A frame interpolation apparatus generates a pixel value at an interpolation position by examining pairs of pixel blocks, one from a preceding reference frame and one from a following reference frame, located in positions that are point-symmetric or nearly point-symmetric with respect to the interpolation position. The pair of pixel blocks showing the greatest mutual similarity is selected, the central pixels in the selected pair of pixel blocks are taken as reference pixels, and the interpolated pixel value is generated from the reference pixel values. By routinely examining a large number of pairs of pixel blocks for each interpolation position, the frame interpolation apparatus can detect image motion accurately and generate accurate interpolated values.
