Image processing device and method

An image processing method implemented in an image processing device, the image processing method comprising:

• generating an image by decoding a bit stream;
• setting a reference list being referred to when the generated image is predicted by inserting a reference image that can be referred to in a layer direction between a plurality of reference images that can be referred to in a time direction;
• and
• predicting the generated image by referring to the set reference list.

An image processing device comprising:

• a reference list setting unit that sets a reference list being referred to when an image is predicted by inserting a reference image that can be referred to in a layer direction between a plurality of reference images that can be referred to in a time direction;
• a prediction unit that predicts the image by referring to the reference list set by the reference list setting unit;
• and
• an encoding unit that generates a bit stream by performing coding using the image predicted by the prediction unit.
