Abstract:
The present disclosure relates to an image processing apparatus and a method that enable efficient change of reference relationship of views in multi-view coding. In the present technology, as for inter-view reference images, a used_by_curr flag is also set to an image having a possibility of being referred, in a slice header or syntax of an SPS. Only an image with the used_by_curr flag of 1 is added to a temporal list used in generating a reference list. Therefore, the temporal list (RefPicListTemp0[rIdx]) of L0 is generated in an order of a short-term (before) reference image of an index 0, a short-term (after) reference image of an index 1, and inter-view reference images of indexes 2 and 3. The present disclosure can be applied to an image processing apparatus, for example.

Claim (Index 1):
An image processing apparatus, comprising:\n a decoding unit configured to decode a bit stream, and generate a first image based on the bit stream; a reference list generating unit configured to generate a default reference list based on identification information that identifies layer reference images of layers, which are set in a video parameter set (VPS), and which are referable, wherein the layer reference images are added to the default reference list, wherein the identification information is set in at least one of a slice parameter set (SPS) or a slice header, and wherein the slice header is at a lower level relative to the VPS; and a prediction unit configured to predict the first image by reference to the default reference list.
