Patent ID: 8300145

Claim:
An apparatus of frame rate up-conversion configured to receive a current image and a previous image and generate at least one intermediate image, the apparatus comprising: a motion vector (MV) detecting circuit for performing forward motion estimation and backward motion estimation to generate a forward MV table, a backward MV table and at least one table of minimum motion estimation (ME) errors according to the current image and the previous image; a control circuit for generating a control signal according to the forward MV table, the backward MV table and the at least one table of minimum ME errors; and a motion compensation circuit for performing corresponding image interpolation in response to the control signal to generate the at least one intermediate image according to the forward MV table, the backward MV table, the current image and the previous image; wherein the control signal is related to one of a high quality mode, at least one intermediate mode and a repeat mode; wherein the sequence of the current image and the previous image corresponds to an original film sequence; wherein in each of the at least one intermediate mode, the at least one intermediate image comprises at least one interpolated image, and the at least one interpolated image is related to the current image and the previous image; and wherein in each of the at least one intermediate mode, an arrangement of the at least one interpolated image keeps an object in the images moving with substantially constant speed.
