3D display system and 3D display method

A three dimensional (3D) display method adapted to a 3D system, comprising:

• when an application is executed by a processor, creating a virtual extend screen which is not displayed on a 3D display, and moving image content of the application to the virtual extend screen;
• obtaining a two-dimensional (2D) content frame of the application from the virtual extend screen by a screenshot function provided by an application programming interface (API) of an operating system;
• converting the 2D content frame into a 3D format frame that includes a left image and a right image by communicating with a third-party software development kit;
• and
• providing the 3D format frame to the 3D display for displaying the left image and the right image in a stereoscopic displaying effect,
• wherein the 3D display provides different images for a left eye and a right eye of a viewer at the same time,
• wherein the method further comprises:
• after the image content of the application executed by the processor is moved to the virtual extend screen, recording the 2D content frame in a frame buffer space corresponding to the virtual extend screen, recording the 3D format frame in a frame buffer space corresponding to the main display screen so that the 3D display served as the main display screen displays the 3D format frame,
• the method further comprising:
• determining whether the 2D content frame conforms to a side-by-side image format;
• and
• if not, converting the 2D content frame to conform to the side-by-side image format.

A three dimensional (3D) display system, comprising:

• a 3D display, providing different images for a left eye and a right eye of a viewer at the same time;
• a memory, recording a plurality of modules;
• and
• one or more processors, connected to the 3D memory and the memory to access and execute the modules recorded in the memory for:
• when an application is executed by a processor, creating a virtual extend screen which is not displayed on the 3D display, and moving image content of the application to the virtual extend screen;
• obtaining a 2D content frame of the application from the virtual extend screen by a screenshot function;
• obtaining a 3D display parameter associated with the 3D display;
• and
• converting the 2D content frame into a 3D format frame that includes a left image and a right image according to the 3D display parameter and an image weaving function and providing the 3D format frame to the 3D display for displaying the left image and the right image in a stereoscopic displaying effect,
• wherein the memory comprises a frame buffer space corresponding to the virtual extend screen and a frame buffer space corresponding to the main display screen, and after the image content of the application executed by the processor is moved to the virtual extend screen, the frame buffer space corresponding to the main display screen records the 3D format frame so that the 3D display served as the main display screen displays the 3D format frame,
• wherein the processor executes the modules for:
• determining whether the 2D content frame conforms to a side-by-side image format;
• if not, converting the 2D content frame to conform to the side-by-side image format.
