Abstract :
In today´s 100 Hz television sets, the display rate is doubled by displaying incoming fields twice. Moving objects are displayed at an incorrect position in the interpolated fields. In the new generation 100 Hz television sets, this artifact is solved by motion-compensated interpolation. Known algorithms for motion estimation and compensation require a huge number of computations. A 3D-recursive block matching algorithm makes possible a one-chip solution. The presented IC is also capable of jitter-free motion portrayal of movie material (25 Hz to 60 Hz upconversion), noise reduction, and vertical zoom.
