FIELD: computer equipment.
SUBSTANCE: invention relates to the computer equipment. Image prediction method comprises steps of: obtaining a first reference unit for an image unit, wherein the same affine model is used for the image unit and the first reference unit; obtaining movement information of basic units of motion compensation in two or more preset positions in first reference unit; and obtaining movement information of the basic unit of motion compensation of the image unit in accordance with movement information of said basic motion compensation units in said two or more preset positions in the first reference unit.
EFFECT: high efficiency of encoding owing to improved accuracy of prediction.
