High efficiency video coding device and method based on reference picture type |
摘要 |
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. |

1. An image processing device comprising:
circuitry configured to:
set a candidate of a predictive vector by setting a co-located vector as unavailable as the candidate of the predictive vector for a coding vector in a current block of a current picture where a reference picture of the coding vector is of a different type of two reference picture types than a reference picture of the co-located vector, wherein the co-located vector is in a co-located block included in a co-located picture of a time different from the current picture but of a same view as the current picture, and wherein the two reference picture types comprise a long-term reference picture type and a short-term reference picture type;generate the predictive vector in the current block according to the candidate of the predictive vector; andencode a difference vector between the coding vector and the generated predictive vector. |
