Method and apparatus to interpolate video frames

A data processing device comprising:

• a processor;
• a machine-readable storage medium coupled to the processor by way of a bus, the storage medium storing a sequence of instructions which, when executed by the processor, cause the data processing device to:
• for a plurality of interpolated pixels in an interpolated video frame:
• classify an interpolated pixel of the plurality as one of stationary, moving, covered, and uncovered;
• and
• if the interpolated pixel is classified as moving, set the interpolated pixel to a weighted sum of a current pixel from a current video frame, the current pixel corresponding to the interpolated pixel in the interpolated video frame, and a previous pixel from a previous video frame, the previous pixel corresponding to the interpolated pixel in the interpolated video frame.

• classifying the interpolated video frame as a bad frame if the interpolated video frame significantly departs from the current video frame and the previous video frame;
• and
• performing error correction on the bad frame.
