Abstract
For encoding and decoding images of the luminance and the opacity which constitute the layer images divided by the front and back relations in the direction of eyes at high efficiency, the apparatus has a deformation analyzer to take the correlation of plane expressing the luminance plane and the opacity, and extract a deformation parameter which is expressed by the affine transformation and the block movement, and a deformation synthesizer which forms a predicted image from the decoding result of the previous frame and the result of the deformation analyzer, the predicted image being composed of the luminance plane and plane, respective difference being subjected to the error coding, and the output bit stream including the affine transformation parameter, the block movement parameter, the luminance plane error code and the plane error code.
