Information Processing Device and Information Processing Method

Abstract

Display of free viewpoint video content is switched so as to alleviate health hazard to viewers without impairing the reality. The omni window is a window integrating all windows, through each of which each sub-content is looked in from main content, and also serves as an entrance to a free viewpoint space of each sub-content. A viewer can go back and forth between different free viewpoint spaces by way of the omni window and the free viewpoint video is switched in accordance with such an exploring motion within the spaces. Furthermore, it is possible to impart a conversion function for a perceived size of the viewer to the omni window.

         6 . The information processing device according to  claim 3 , wherein the sub-content is selected based on attribute information of the viewer. 
     
     
         7 . The information processing device according to  claim 3 , wherein the sub-content is selected based on a viewing situation of the viewer. 
     
     
         8 . The information processing device according to  claim 3 , wherein sub-content is selected when operation of the viewer is detected. 
     
     
         9 . The information processing device according to  claim 2 , wherein the circuitry is configured to change the at least one window includes changing a size of the at least one window within the field of view of a viewer based on the distance between the viewer and the at least one window. 
     
     
         10 . The information processing device according to  claim 2 , wherein the circuitry is configured to change the at least one window includes changing video through the at least one window based on a viewing direction of the viewer and a viewing position of the viewer. 
     
     
         11 . The information processing device according to  claim 2 , wherein the circuitry is further configured to determine a position of the at least one window within the main content. 
     
     
         12 . The information processing device according to  claim 11 , wherein the position of the at least one window is determined based on a certain object within the main content. 
     
     
         13 . The information processing device according to  claim 2 , wherein the circuitry is to determine a display position within the sub-content based on a past viewing history of the viewer. 
     
     
         14 . A method comprising:
 displaying at least one window within a free viewpoint space of a main content, the at least one window related to sub-content;   changing the at least one window within a field of view of a viewer based on a distance between the viewer and the at least one window; and   switching the main content to the sub-content in response to passing through a window frame of the at least one window.   
     
     
         15 . The method according to  claim 14 , comprising selecting the sub-content as a candidate for a display by switching destination from the main content currently being displayed. 
     
     
         16 . The method according to  claim 15 , wherein the sub-content is selected based on information included in screen. 
     
     
         17 . The method according to  claim 16 , wherein the sub-content is selected based on whether or not a certain feature point or object is included. 
     
     
         18 . The method according to  claim 15 , wherein the sub-content is selected based on attribute information of the viewer. 
     
     
         19 . The method according to  claim 15 , wherein the sub-content is selected based on a viewing situation of the viewer. 
     
     
         20 . The method according to  claim 15 , wherein sub-content is selected when operation of the viewer is detected. 
     
     
         21 . The method according to  claim 14 , wherein changing the at least one window includes changing a size of the at least one window within the field of view of a viewer based on the distance between the viewer and the at least one window. 
     
     
         22 . The method according to  claim 14 , wherein changing the at least one window includes changing video through the at least one window based on a viewing direction of the viewer and a viewing position of the viewer. 
     
     
         23 . The method according to  claim 14 , comprising determining a position of the at least one window within the main content. 
     
     
         24 . The method according to  claim 23 , wherein the position of the at least one window is determined based on a certain object within the main content.
