Abstract
A video-image-interpolation apparatus is provided, which includes at least three image-layering circuits, at least three motion-estimation circuits, a motion-estimation-filtering circuit, a motion-compensated frame-interpolation circuit, and a display-control circuit. Each motion-estimation circuit performs motion estimation on a reference image-layer sequence and a reference subtitle-layer sequence that are generated from an input video signal by each image-layering circuit. The motion-estimation-filtering circuit adaptively determines the motion-estimation circuit having the smallest motion error. The motion-compensated frame-interpolation circuit performs motion compensation to generate one or more interpolated image-layer images and one or more interpolated subtitle-layer images according to the motion vectors calculated by the motion-estimation circuit having the smallest motion error, and superimposes the one or more interpolated image-layer images and the one or more interpolated subtitle-layer images to generate interpolated images. The display-control circuit performs frame-rate conversion on the reference images and the interpolated images to obtain an output video signal.
