Abstract: There is provided an encoding apparatus and an encoding method that make it possible to generate an encoded stream from which an image of a low load and high picture quality can be decoded. An arithmetic operation section or the like divides an image into a plurality of AUs and encodes the AUs to generate encoded streams of the plurality of AUs. A setting section sets 0 as pic_output_flag indicating that a decoded image obtained by decoding an encoded stream of an AU other than the last division AU from among the encoded streams of the plurality of AUs generated by the arithmetic operation section or the like is not to be displayed. The present disclosure can be applied, for example, to an encoding apparatus and so forth.

Abstract: The present disclosure relates to an image processing apparatus and an image processing method that enable generation of only a 3D model of a foreground. A reconstruction unit generates a 3D model of the foreground, on the basis of depth images of a plurality of viewpoints and foreground images of the plurality of viewpoints. The present disclosure can be applied to a decoding apparatus or the like that decodes an encoded stream of depth-related images and color images of a 3D model of a plurality of viewpoints, and generates a 3D model of the foreground on the basis of the resultant depth-related images and color images, and virtual viewpoint information including internal parameters and external parameters for virtual cameras of the respective viewpoints, for example.

Abstract: There is provided a video reproduction apparatus, a reproduction method, and a program that can suppress a decline in the degree of immersion of a viewer. A video generation apparatus of the present disclosure acquires a first 3D shape video generated from a plurality of viewpoint videos obtained by capturing images of a subject from different viewpoints, and a second 3D shape video being a video different from the first 3D shape video, and switches a frame to be reproduced, from a frame of the first 3D shape video to a frame of the second 3D shape video on the basis of a state of a viewer viewing the first 3D shape video. The present disclosure may be applied, for example, to a video generation apparatus, a video processing apparatus, a video reproduction apparatus, or the like.

Abstract: There is provided an image processing apparatus and an image processing method that enable selection of viewpoints of depth images suitable for creation of a 3D model. A viewpoint determination unit determines that a candidate viewpoint be a viewpoint of a depth image of a 3D model on the basis of the 3D model projected on a screen from the candidate viewpoint. The present disclosure can be applied to, for example, an encoding device or the like that generates and encodes color images and depth images from predetermined viewpoints, from color images and depth images from a plurality of viewpoints of a 3D model of a subject.
