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 operate as:
a predictive motion vector generating unit that sets a co-located block to be not available when a type of a reference picture of a current block is different from a type of the reference picture of a co-located block included in a co-located picture when encoding a current motion vector of the current block used in prediction using correlation in a temporal direction and generates a predictive motion vector of the current motion vector using a reference motion vector referred when generating a predictive motion vector; anda difference motion vector generating unit that generates a difference motion vector between the current motion vector and the predictive motion vector generated by the predictive motion vector generating unit.
