<p>The present invention relates to an image processing device and method with which decoding processing can be performed at the correct timing. A HRD-type setting unit determines, on the basis of a user instruction, a HRD-parameter type, i.e. parameters for managing a decoder buffer, and acquires, from a storage buffer and a storage buffer (subordinate tier) of a base-layer image encoder, information indicating a storage state, in accordance with the determined HRD-parameter type. The HRD-type setting unit calculates HRD parameters on the basis of the acquired information, and causes the HRD parameters and flags indicating the HRD-parameter type to be encoded in a reversible encoder. The present invention is application to image processing devices.</p> |
