Abstract
A motion vector estimator includes an object data input and sorting unit and a reference data input and sorting unit for sorting packed input picture data to separate first picture data used for estimating the motion vector from second picture data that is not used for estimating the motion vector and pack the picture data again respectively, an object data storing unit and a reference data storing unit for storing the repacked first picture data and the second picture data, and a motion vector calculating unit for reading the first picture data from the object data storing unit and the reference data storing unit to perform a calculation for estimating the motion vector.
Claims23
A motion vector estimating method applying a sub-sampling method to a picture of an object frame and a picture of a reference frame in a motion picture compressing and encoding process, the method comprising:
- sorting the picture of the object frame and the picture of the reference frame in accordance with the sub-sampling method to separate first picture data used for estimating a motion vector from second picture data that is not used for estimating the motion vector and pack the data;
- and
- estimating the motion vector by using the packed first picture data.
A motion picture processor having a motion vector estimator that applies a sub-sampling method to a picture of an object frame and a picture of a reference frame to estimate a motion vector and performs a motion picture compressing and encoding process, the motion picture processor comprising:
- an object data input and sorting unit for sorting the picture of the object frame in accordance with the sub-sampling method to separate first object picture data used for estimating the motion vector from second object picture data that is not used for estimating the motion vector and pack the data respectively;
- a reference data input and sorting unit for sorting the picture of the reference frame in accordance with the sub-sampling method to separate first reference picture data used for estimating the motion vector from second reference picture data that is not used for estimating the motion vector and pack the data respectively;
- an object data storing unit for storing the packed first object picture data and the second object picture data;
- a reference data storing unit for storing the packed first reference picture data and the second reference picture data;
- and
- a motion vector calculating unit for reading the first object picture data from the object data storing unit and reading the first reference picture data from the reference data storing unit to perform a calculation for estimating the motion vector.
