Abstract

The present technique relates to an image processing device and method capable of suppressing a decrease in encoding efficiency. The image processing device includes: a predictive vector generating unit that generates a predictive vector of a current parallax vector of a current block used in prediction using correlation in a parallax direction using a reference parallax vector referred when generating a predictive motion vector, when encoding the current parallax vector; and a difference vector generating unit that generates a difference vector between the current parallax vector and the predictive vector generated by the predictive vector generating unit. The present disclosure can be applied to an image processing device.

Claims6

Dependent claims

An image processing device comprising:

circuitry configured to operate as:
a predictive motion vector generating unit that:
sets a co-located vector to be available and to be scaled in a candidate list as a condition that both a type of a reference picture of a current block and a type of a reference picture of a co-located block are short-term reference pictures;
sets the co-located vector to be available and to be not scaled in the candidate list as a condition that both the type of the reference picture of the current block and the type of the reference picture of the co-located block are long-term reference pictures;
generates a predictive motion vector of a coding vector of the current block using the candidate list;
and
a reconstructing unit that reconstructs the coding vector by using the predictive motion vector generated by the predictive motion vector generating unit;
and
a decoding unit that decodes the current block using the coding vector reconstructed by the reconstructing unit.
