Patent ID: 8300146

Claim:
A display frequency boosting system, for increasing image display frequency, comprising: a buffer having an input terminal and six field buffers to receive image data from a first frame, a second frame, and a third frame respectively, and store the frames in a form of zero to fifth fields, wherein each of the frames is composed of an odd field and an even field; a motion estimation device, connected to the buffer, for performing a motion estimation on the fields to produce a motion vector; an interpolator, connected to the buffer, for performing an interpolation on the fields to produce an interpolated field; a motion compensation device, connected to the buffer, the motion estimation device and the interpolator, for performing a motion compensation according to the fields stored in the buffer, the interpolated field and the motion vector so as to produce a sixth field and a seventh field; and a controller, connected to the buffer, for controlling read and write operations of the buffer, wherein the controller controls the buffer in a first time interval in order to write the fourth field in the buffer, read the zero field and the first field out of the buffer and output the first frame corresponding to the zero field and the first field, and the controller controls the buffer in a second time interval in order to write the fifth field in the buffer and read the zero field, the first field and the second field out of the buffer; wherein a fourth frame corresponding to the sixth field and the seventh field locates between the first frame and the second frame in a display time axis; wherein the motion estimation device performs the motion estimation on the zero field and the second field in the second time interval to produce the motion vector; wherein the interpolator performs the interpolation on the second field in the second time interval to produce the interpolated field; and wherein the motion compensation device is based on the motion vector, the zero field and the second field to perform the motion compensation in the second time interval so as to produce the sixth field.
