<p>A decoding method generates a rectangular residual image by performing an inverse quantization and inverse frequency conversion processes based on coefficient data, a rectangular predicted image by reading a reference image based on motion vector data, and a decoded image by adding the residual image and the predicted image. The predicted images with respect to at least two or more rectangular regions are stored when generating the rectangular predicted image, and a predicted image ready signal notifies that the predicted image with respect to the at least two or more rectangular regions has been generated. The timings to store the coefficient data and the motion vector data are controlled in response to the predicted image ready signal.</p> |
