Pixel-intensity modulation technique for frame-sequential stereo-3D displays

摘要

Discloses herein are methods, apparatuses, and systems for preparing and displaying images in frame-sequential stereoscopic 3D. Frame-sequential stereoscopic display includes an alternating sequence of left- and right-perspective images for display. Disclosed methods include identifying pixels that modulate due to the alternating sequence of left- and right-perspective images of the frame-sequential stereoscopic display. The disclosed methods also include processing the pixels to reduce one or more residual images caused by the alternating sequence of left- and right-perspective images of the frame-sequential stereoscopic display. The disclosed methods may be implemented by a processing unit and the processing unit may be included in a system (such as, a computer or video-game console).

主权项

1. A method, comprising:
arranging alternating first-perspective and second-perspective images for frame-sequential stereoscopic display into a sequence comprising a first string of multiple first-perspective images and a second string of multiple second-perspective images for display; altering a pixel intensity of a first boundary image in the first string, wherein the first boundary image is next to a boundary between the first string and the second string, such that the pixel intensity of the first boundary image is closer to a pixel intensity of a second boundary image in the second string, wherein the second boundary image is next to the boundary between the first string and the second string; and adjusting a pixel intensity of a second image in the first string such that an average pixel intensity of images in the first string remains substantially the same.
