Playback device that can play stereoscopic video, integrated circuit, playback method and program

A playback method that is used in a computer that includes a platform that activates and executes a bytecode application, the bytecode application issuing a request for rendering graphics, and a left-view graphics plane and a right-view graphics plane, the method comprising:

• receiving the request from the bytecode application;
• and
• switching a current plane setting between a one-plane setting and a two-plane setting, the one-plane setting being a setting with which one of the left-view graphics plane and the right-view graphics plane is used for rendering the graphics at a time of monoscopic playback and stereoscopic playback of the graphics, the two-plane setting being a setting with which both of the left-view graphics plane and the right-view graphics plane are used for rendering the graphics at a time of stereoscopic playback of the graphics, wherein
• the request is either a request for rendering 2D graphics or a request for rendering 3D graphics, and
• when the switching switches the current plane setting from the one-plane setting to the two-plane setting and the request for rendering the 2D graphics has been issued before the switching switches the current plane setting from the one-plane setting to the two-plane setting, before the request for rendering the 3D graphics is accepted, first processing is performed of invalidating the request for rendering the 2D graphics, second processing is performed of copying the 2D graphics stored in the one of the left-view graphics plane and the right-view graphics plane having been used for rendering the 2D graphics to the other of the left-view graphics plane and the right-view graphics plane, and third processing is performed of outputting the 2D graphics stored in each of the left-view graphics plane and the right-view graphics plane.

A non-transitory computer readable recording medium storing a program that operates on a computer that includes a platform that activates and executes a bytecode application, the bytecode application issuing a request for rendering graphics, and a left-view graphics plane and a right-view graphics plane, the program causing the computer to perform:

• receiving the request from the bytecode application;
• and
• switching a current plane setting between a one-plane setting and a two-plane setting, the one-plane setting being a setting with which one of the left-view graphics plane and the right-view graphics plane is used for rendering the graphics at a time of monoscopic playback and stereoscopic playback of the graphics, the two-plane setting being a setting with which both of the left-view graphics plane and the right-view graphics plane are used for rendering the graphics at a time of stereoscopic playback of the graphics, wherein
• the request is either a request for rendering 2D graphics or a request for rendering 3D graphics, and
• when the switching switches the current plane setting from the one-plane setting to the two-plane setting and the request for rendering the 2D graphics has been issued before the switching switches the current plane setting from the one-plane setting to the two-plane setting, before the request for rendering the 3D graphics is accepted, first processing is performed of invalidating the request for rendering the 2D graphics, second processing is performed of copying the 2D graphics stored in the one of the left-view graphics plane and the right-view graphics plane having been used for rendering the 2D graphics to the other of the left-view graphics plane and the right-view graphics plane, and third processing is performed of outputting the 2D graphics stored in each of the left-view graphics plane and the right-view graphics plane.
