Abstract:
Systems and methods for converting a picture frame rate from a source video at a first rate to a target video at a second rate via interpolation of an intermediate frame. In one implementation, the system includes a phase plane correlation calculator including a low pass filter and a high pass filter for receiving previous frame data and current frame data where the phase plane correlation calculator is configured to generate a first motion vector based upon low pass representations and high pass representations. The system may also include a motion compensated interpolator that receives the first motion vector and an additional input motion vector and determines a final motion vector for use in interpolation. The system may further include an intermediate frame generator configured to generate the intermediate frame utilizing the final motion vector.
