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.
Claims15
A frame rate conversion apparatus comprising:
- a motion vector detecting unit comparing previous and current video data and detecting a motion vector based on the compared result;
- a motion vector compensating unit compensating for an error in the detected motion vector based on adjacent motion vectors and generating a compensated motion vector;
- and
- a motion vector selecting unit selecting one of the detected motion vector and the compensated motion vector based on the error in the detected motion vector and an error in the compensated motion vector.
A frame rate conversion method comprising:
- comparing current and previous video data and detecting a motion vector based on the compared result;
- compensating an error in the detected motion vector based on adjacent motion vectors;
- and
- selecting one of the detected motion vector and a compensated motion vector as a final motion vector, based on errors in the detected and compensated motion vectors.
