Abstract:
With an image coding method which allows reduction of processing loads, when pictures included in a video signal are classified into layers so as to belong to their respective layers, a picture that belongs to the second layer that is located in a range restricted according to the first layer to which a current picture to be coded that is one of the pictures belongs, is referred to as a reference picture for the current picture, and the current picture is coded based on the reference picture.
