Abstract
A display frequency boosting system for increasing image display frequency includes a buffer to receive a first frame, a second frame, and a third frame of image data and store the frames in a form of zero to fifth fields, a motion estimation device to perform a motion estimation on the fields to produce a motion vector, an interpolator connected to the buffer to perform an interpolation on the fields to produce an interpolated field, a motion compensation device to perform a motion compensation according to the motion vector, the fields and the interpolated field to produce sixth and seventh fields, and a controller to control read and write operations of the buffer, wherein each frame is composed of an odd field and an even field, and a fourth frame corresponding to the sixth and the seventh fields locates between the first and second frames in a display time axis.
