Abstract
A method and apparatus for motion estimation in which the amount of computation can be reduced are provided. The method for motion estimation includes storing an interblock match difference calculated for a previous matching block to be motion estimated, calculating an interblock match difference for a current matching block to be motion estimated using the stored interblock match difference, and performing motion estimation on the current matching block using the interblock match difference calculated for the current matching block.
Claims18
A method for motion estimation, the method comprising:
- storing an interblock match difference calculated for a portion of a previous matching block to be motion estimated which is overlapped with a current matching block to be motion estimated;
- calculating an interblock match difference for the current matching block to be motion estimated by adding the interblock match difference which is stored and an interblock match difference calculated for a portion of the current matching block which is not overlapped with the previous matching block;
- and
- performing motion estimation on the current matching block using the interblock match difference calculated for the current matching block.
A method for motion estimation, the method comprising:
- reading a half of an interblock match difference for a previous matching block from a memory;
- calculating a half of an interblock match difference for a current matching block to be motion estimated;
- adding the read half and the calculated half to determine the interblock match difference for the current matching block;
- and
- performing motion estimation on the current matching block using the interblock match difference.
An apparatus for motion estimation, the apparatus comprising:
- a storing unit which stores an interblock match difference calculated for a portion of a previous matching block to be motion estimated which is overlapped with a current matching block to be motion estimated;
- a predicting unit which calculates an interblock match difference for the current matching block to be motion estimated by adding the interblock match difference which is stored and an interblock match difference calculated for a portion of the current matching block which is not overlapped with the previous matching block;
- and
- a motion vector determining unit which performs motion estimation on the current matching block using the interblock match difference calculated for the current matching block.
An apparatus for motion estimation, the apparatus comprising:
- a match difference storing unit which stores a half of an interblock match difference for a previous matching block;
- a predicting unit which calculates a half of an interblock match difference for a current matching block to be motion estimated and adds the stored half and the calculated half to determine the interblock match difference for the current matching block;
- and
- a motion vector determining unit which performs motion estimation on the current matching block using the interblock match difference.
