Information processing apparatus and information processing method
View Patent ↗There is provided an information processing apparatus and an information processing method which are capable of reliably recognizing the position on a screen of an image made up of a plurality of divided images or the positions on the screen of divided images compatible with encoded streams.

5. The information processing apparatus according to claim 4 , wherein the position of the one continuous image on the screen is set in a management file for managing files of the encoded stream.
6. An information processing method, executed via at least one processor, the method comprising:
obtaining an image by dividing an entire celestial sphere image or a panoramic image into a plurality of partial images;
generating an encoded stream such that a first partial image of the plurality of partial images constituting a first end portion and a second partial image of the plurality of partial images opposite to the first partial image comprise one continuous image among the plurality of partial images; and
allocating the image obtained by decoding the encoded stream on a screen, on the basis of a position protruding out of the screen which is set as a position of the one continuous image with respect to the entire celestial sphere image or the panoramic image.
7. An information processing apparatus comprising:
an image obtaining section configured to obtain an image by dividing an entire celestial sphere image or a panoramic image into a plurality of partial images;
a generating section configured to generate an encoded stream such that a first partial image of the plurality of partial images constituting a first end portion and a second partial image of the plurality of partial images opposite to the first partial image comprise one continuous image among the plurality of partial images; and
a setting section configured to set positions on a screen of respective partial images of the plurality of partial images, including a position of the one continuous image with respect to the entire celestial sphere image or the panoramic image,
wherein the image obtaining section, the generating section, and the setting section are each implemented via at least one processor.
8. The information processing apparatus according to claim 7 , wherein the encoded stream comprises the plurality of partial images encoded as different tiles.
9. The information processing apparatus according to claim 7 , wherein the setting section sets the position of the one continuous image on the screen in a management file for managing files of the encoded stream.
10. An information processing method, executed via at least one processor, the method comprising:
