Graphics processing method for three-dimensional images applied to first buffer for storing right-view contents and second buffer for storing left-view contents and related graphics processing apparatus thereof

A graphics processing apparatus for three-dimensional images, comprising:

• a first buffer, arranged to store right-view contents in a single-buffer mode;
• a second buffer, arranged to store left-view contents in the single-buffer mode;
• a display engine, coupled to the first buffer and the second buffer, arranged to display the right-view contents stored in the first buffer during a right Vsync period of a right-view frame, and arranged to display the left-view contents stored in the second buffer during a left Vsync period of a left-view frame;
• and
• a drawing engine, coupled to the first buffer, the second buffer, and the display engine, arranged to draw the right-view contents stored in the first buffer only when a Vsync status indicates that the display engine is not operating within the right Vsync period of the right-view frame, and arranged to draw the left-view contents stored in the second buffer only when the Vsync status indicates that the display engine is not operating within the left Vsync period of the left-view frame.

A graphics processing method for three-dimensional images, applied to a first buffer for storing first-view contents and a second buffer for storing second-view contents in a single-buffer mode, the method comprising:

• when a vertical synchronization (Vsync) status indicates that a display engine is not operating within a first Vsync period of a first-view frame, the drawing engine drawing the first-view contents stored in the first buffer;
• when the Vsync status indicates that the display engine is not operating within a second Vsync period of a second-view frame, the drawing engine drawing the second-view contents stored in the second buffer;
• during the first Vsync period of the first-view frame, the display engine displaying the first-view contents stored in the first buffer;
• and
• during the second Vsync period of the second-view frame, the display engine displaying the second-view contents stored in the second buffer.
