Abstract
A motion estimation and motion compensation (MEMC) system with calibration function and a parameter calibration method thereof relate to a parameter calibration method for MEMC. The parameter calibration method is configured to calibrate an MEMC program. The parameter calibration method includes storing a default feature set; performing the MEMC program on a calibrated video to fetch a testing feature set; generating a calibration parameter according to a difference vale between the default feature set and the testing feature set; and adjusting a correction parameter of the MEMC calibration program in accordance with the calibration parameter.
Claims16
A motion estimation and motion compensation system with correction function, wherein
- the motion estimation and motion compensation system comprises:
- a storage unit, configured to store a default feature set of at least one specified pattern feature;
- a motion estimation and motion compensation system (MEMC) unit, configured to receive a calibrated video and perform an MEMC program on the calibrated video so as to fetch a testing feature set;
- and
- a processing unit, connected to the storage unit and the MEMC unit, and configured to generate a calibration parameter in accordance with a difference value between the default feature set and the testing feature set;
- wherein, the MEMC unit is further configured to correct an output result of the MEMC program in accordance with the calibration parameter.
