Problems solved by technology

[0003] However, in such a two-viewpoint mode, the viewer needs to purchase glasses in addition to the 3D image display device, and therefore, the viewer's willingness to purchase decreases.
Also, this annoys the viewer as the viewer needs to wear glasses for viewing

[0116] [Configuration Example of Encoding Device According to First Embodiment]

[0117] Figure 5 is a block diagram showing a configuration example of an encoding device according to the first embodiment of the present technology.

[0118] Figure 5 The illustrated encoding device 50 is composed of imaging units 51A to 51C, an image converting unit 52, a parallax image generating unit 53, an image information generating unit 54, a compatibility information generating unit 55, an inter-viewpoint distance information generating unit 56, a parallax image information generating unit 57 , an encoder 58 and a multiplexing unit 59 constitute.

[0119] The encoding device 50 encodes an image of one view included in a multi-view image as a 2D image according to an existing encoding mode, thereby ensuring compatibility with an existing encoding device that encodes a 2D image.

[0120] Hereinafter, among multi-viewpoint images, an image encoded in an existing encoding mode so as to ...

[0260] [Configuration Example of Encoding Device According to Third Embodiment]

[0261] Figure 19 is a block diagram showing a configuration example of an encoding device according to a third embodiment of the present technology.

[0262] exist Figure 19 In the configuration shown, the same reference numerals have been given to the Figure 5 or the same configuration as shown in 14. Duplicate descriptions will be appropriately omitted.

[0263] Figure 19 The configuration of encoding device 180 is shown with Figure 14 The main difference of the illustrated configuration is that an image conversion unit 181 and an encoder 182 are arranged instead of the image conversion unit 142 and the encoder 145 . The encoding device 180 ensures compatibility with existing encoding devices that encode 3D images in two-viewpoint mode by encoding images of two viewpoints among multi-viewpoint images as compatible images according to the MVC mode.

Abstract

The present invention pertains to an encoding device, an encoding method, a decoding device, and a decoding method which enable encoding and decoding of multi-view images using a method compatible with current methods. A compatibility encoder encodes an image (A1) that is a compatible image and generates a compatible stream. An image converter converts the resolution of an image (B1) that is an auxiliary image and an image (C1). An auxiliary encoder encodes an auxiliary image for which the resolution has been converted and generates an encoded auxiliary image stream. A compatibility data generation unit generates, as compatibility data, data specifying the image (A1) as the compatible image. A multiplexing unit transmits the compatible stream, the encoded auxiliary image stream, and the compatibility data. The present invention can be applied, for example, to an encoding device that encodes multi-view 3D images.

Description

technical field [0001] The present technology relates to an encoding device, an encoding method, a decoding device, and a decoding method, and more particularly, to an encoding device, an encoding method, and a decoding device capable of encoding and decoding multi-viewpoint images according to a mode compatible with existing modes and decoding methods. Background technique [0002] Currently, as a 3D image viewing mode, generally, there is a view of two-viewpoint images displayed alternately by wearing glasses in which the shutter for the left eye is opened when one of the two-viewpoint images is displayed and the shutter for the right eye is opened when the other image is displayed. mode (hereinafter referred to as the two-viewpoint mode). [0003] However, in such a two-viewpoint mode, the viewer needs to purchase glasses in addition to the 3D image display device, and therefore, the viewer's willingness to purchase decreases. In addition, this annoys the viewer since t...
