ABSTRACT:
Provided are a method and apparatus for performing frame rate conversion. With the apparatus, current video data and previous video data are compared with each other and a motion vector is detected based on the compared result; an error in the detected motion vector is compensated for based on adjacent motion vectors; and one of the detected motion vector and a compensated motion vector is selected as a final motion vector, based on errors in the detected and compensated motion vectors. Accordingly, a more reliable motion vector can be selected to perform frame rate conversion, thereby more naturally depicting an image.
