Abstract
A system to interpolate between a number of images for the purpose of frame rate conversion may include a motion vector interpolator, a motion compensation module, and a protector. The motion vector interpolator may segment a motion vector into portions based on temporal distances of a target image from each of the number of images. The motion compensation module may generate at least two motion compensated values for a pixel in the target image based on the portions of the motion vector. The protector may choose a motion compensated value for the pixel in the target image when the motion vector is accurate and may choose a pixel value from one of the number of images when the motion vector is not accurate.
