Abstract
Disclosed is an image coding method and apparatus for preventing a coding quantity of coding data from being increased when a redundancy between image planes is low. A selector outputs either an optimum motion vector output from a motion vector detecting device or a motion vector output from a motion vector storing section to a real time image coding device for performing coding on the basis of an evaluation value output from the motion vector detecting device. If it is decided, according to the evaluation value, that a redundancy between a reference image plane and a coding object image plane is low, the motion vector is selected so that the coding quantity of the coding data can be prevented from being increased.
