Kind Code:
A1
Abstract:
The embodiments of the present application disclose a motion vector acquiring method, comprising: determining a reference block of a block to be processed, the reference block and the block to be processed having a preset time domain or spatial domain correlation, the reference block having an initial motion vector and one or more preset motion vector offsets, the initial motion vector of the reference block being obtained on the basis of a predicted motion vector of the reference block, and a predicted block of the reference block being obtained on the basis of the initial motion vector and the one or more preset motion vector offsets; and using the initial motion vector of the reference block as a predicted motion vector of the block to be processed.
