Abstract
Official abstract text for this publication.
A method for reducing motion blur in a video signal of a head mounted display apparatus is provided. The method includes the following steps. Receive the video signal including a first frame and a second frame. Track an eye movement of a user to determine a user view area. Generate an intermediate frame between the first frame and the second frame. Provide the first frame, the intermediate frame, and the second frame for display. The step of generating the intermediate frame includes synthesizing pixel values only in the user view area of the intermediate frame.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for reducing motion blur in a video signal of a head mounted display apparatus, the method comprising: receiving the video signal comprising a first frame and a second frame by a display driver; tracking an eye movement of a user to determine a user view area, wherein the user view area is less than a complete frame; generating an intermediate frame between the first frame and the second frame; and providing the first frame, the intermediate frame, and the second frame for display; wherein the step of generating the intermediate frame comprises synthesizing pixel values only in the user view area of the intermediate frame based on the eye movement of the user and performing motion estimation and motion compensation only in the user view area of the intermediate frame based on the eye movement of the user. 2. The method according to claim 1 , wherein pixel values of the intermediate frame are the same as pixel values of the first frame except in the user view area. 3. The method according to claim 1 , wherein pixel values of the intermediate frame are the same as pixel values of the second frame except in the user view area. 4. The method according to claim 1 , wherein the user view area comprises a left eye view area and a right eye view area. 5. A head mounted display apparatus, comprising: a display driver receiving a video signal comprising a first frame and a second frame; an eye tracking device, configured to track an eye movement of a user to determine a user view area, wherein the user view area is less than a complete frame; wherein the display driver is further configured to synthesize pixel values only in the user view area of an intermediate frame based on the eye movement of the user and perform motion estimation and motion compensation only in the user view area of the intermediate frame based on the eye movement of the user, wherein the intermediate frame is inserted between the first frame and the second frame; and a display panel, driven by the display driver to display the first frame, the intermediate frame, and the second frame. 6. The head mounted display apparatus according to claim 5 , wherein the display driver is configured to duplicate pixel values of the first frame except in the user view area to generate the intermediate frame. 7. The head mounted display apparatus according to claim 5 , wherein the display driver is configured to duplicate pixel values of the second frame except in the user view area to generate the intermediate frame. 8. The head mounted display apparatus according to claim 5 , wherein the display driver is configured to modify pixel values in the user view area of the intermediate frame using frame interpolation. 9. The head mounted display apparatus according to claim 5 , wherein the user view area comprises a left eye view area and a right eye view area.
