Abstract: There is provided an encoding apparatus, an encoding method, a decoding apparatus, and a decoding method that make it possible to acquire two-dimensional image data of a viewpoint corresponding to a predetermined display image generation method and depth image data without depending upon the viewpoint upon image pickup. A conversion unit generates, from three-dimensional data of an image pickup object, two-dimensional image data of a plurality of viewpoints corresponding to a predetermined display image generation method and depth image data indicative of a position of each of pixels in a depthwise direction of the image pickup object. An encoding unit encodes the two-dimensional image data and the depth image data generated by the conversion unit. A transmission unit transmits the two-dimensional image data and the depth image data encoded by the encoding unit. 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 make it possible to generate a high picture quality texture image of a predetermined viewpoint using an omnidirectional image. A reception section receives a texture image and a depth image as well as a guide image to be referred to upon generation of a display image in which the texture image and the depth image are used. A drawing section compares a pixel value of the display image generated using the texture image and the depth image and a corresponding pixel value of the guide image with each other and executes a process for changing the pixel value in response to a result of the comparison. The present disclosure can be applied, for example, to a home server or the like that generates a display image of a predetermined viewpoint from an omnidirectional image.

Abstract: The present invention relates to an image processing device and method enabling deterioration in encoding efficiency to be suppressed.
A control information adding unit 184 embeds one picture worth of control information held in a control information holding unit 183 into a slice header of a predetermined slice, in encoded data held in an encoded data holding unit 182. For example, the control information adding unit 184 embeds one picture worth of control information in the slice header of the first-transmitted slice in the frame to be processed in the encoded data. The control information adding unit 184 outputs encoded data to which the control information has been added, in a predetermined order. The present invention can be applied to, for example, an image processing device.
