Description

  The present disclosure relates to an information processing apparatus and an information processing method.

  In recent years, an apparatus capable of displaying content including a three-dimensional (hereinafter sometimes referred to as “3D”) image such as content transmitted in stereoscopic television broadcasting or a stereoscopic movie has been widely used. Here, the image data indicating the content as described above is not limited to image data indicating an image composed of only a 3D image, and for example, a two-dimensional (hereinafter sometimes referred to as “2D”) image and a 3D image. In some cases, the image data indicates a mixed image.

  Under such circumstances, techniques for processing images including 3D images have been developed. As a technique for separating input data into image data and control data and generating image data consisting of only a 2D image and image data consisting of only a 3D image based on the control data, for example, described in Patent Document 1 Technology.

  Also, for example, a usage mode in which image data such as image data indicating content transmitted in a television broadcast is recorded on a recording medium, and the image data stored in the recording medium is reproduced to enjoy the content is generalized.

  Under such circumstances, techniques relating to reproduction processing of image data stored in a recording medium have been developed. As a technique for reproducing a summary of the content by extracting a specific portion from the content indicated by the data stored in the recording medium and connecting the extracted portions for reproduction, for example, Patent Document 2 The technique described in is mentioned.

JP 2005-094145 A JP 2008-206076 A

  For example, the technique described in Patent Document 1 separates control data from input data to be processed, and generates image data consisting of only a 2D image and image data consisting of only a 3D image based on the control data. However, for example, when the technique described in Patent Document 1 is used, when the user desires to reproduce content including only 2D images, the user reproduces image data including only 2D images, and reproduces content including only 3D images. It is necessary to reproduce image data consisting only of 3D images. Therefore, for example, even if the technique described in Patent Document 1 is used, based on image data in which a two-dimensional image section (2D image portion) and a three-dimensional image section (3D image portion) are mixed, for example, a two-dimensional image There is no way to realize reproduction of only a section, reproduction of only a three-dimensional image section, or the like.

  Further, for example, by using the technique described in Patent Document 2, it is possible to extract a specific portion from the content indicated by the data stored in the recording medium and reproduce the content summary. However, for example, in the technique described in Patent Document 2, no consideration is given to extracting a two-dimensional image section and a three-dimensional image section from data stored in a recording medium. Therefore, for example, even if the technique described in Patent Document 2 is used, it is not desired to realize reproduction of only a two-dimensional image section, reproduction of only a three-dimensional image section, or the like.

  The present disclosure proposes a new and improved information processing apparatus and information processing method capable of generating a reproduction list that defines a reproduction section of image data in which two-dimensional image sections and three-dimensional image sections are mixed. To do.
