Claim 4:
5. The method of claim 1, wherein:
determining the group of control point motion vectors includes:
scanning left neighboring blocks of the current image block according to a first scanning order, and, in response to reaching a first left neighboring block, determining one or more control point motion vectors of the first left neighboring block using the affine transformation mode for prediction; and
scanning upper neighboring blocks of the current image block according to a second scanning order, and, in response to reaching a first upper neighboring block, determining one or more control point motion vectors of the first upper neighboring block using the affine transformation mode for prediction; and

adding the group of control point motion vectors to the motion vector candidate list includes:
adding the one or more control point motion vectors of the first left neighboring block and the one or more control point motion vectors of the first upper neighboring block into the motion vector candidate list of the current image block as candidates.
